PUBLISHEr's VIEW SG 6
'Foolhardy'. That's how SA Public Enterprises Minister Malusi Gigaba has described any rushing into new nuclear power station builds, before dealing with a number of concerns, not least being safety. And that's not even to mention the cost, conservatively estimated at R300bn but more likely to run to the higher-end estimation of R1tn or more, once all is said and done. South Africa simply doesn't have the money for this sort of infrastructural capital expenditure, regardless of the additional power demands that are not only troubling the country's power producer Eskom currently, but will become extremely acute by 2017. So, foolhardy indeed, we would say in full agreement with the minister, regarding SA's current plans to install several new-generation nuclear power stations. And these plants take a long time to build, so even if we were to start building tomorrow, the 2017 power bottleneck will have come and gone by the time any more power comes from nuclear sources for our national grid. Conservatively-minded folk like to say that we cannot provide for our base-load energy needs without resorting to coal and nuclear. The latter is preferable, such people say, since when it's working and not dangerously broken, like the six reactors at Fukushima – some of which are currently spewing radioactive particles and radiation all over the place – nuclear is actually 'cleaner' than coal. These people are both right and wrong. Nuclear is clearly a cleaner source of power – and more cost-effective – than coal, when it's working. The problem is that when nuclear goes bad, things become very serious indeed. It may be that the exclusion zone around Fukushima ends up at around 50km, perhaps 100km say some experts, depending on whether Tepco, its owners, can get things under control, which is a pretty big assumption at this point. And that still leaves the unsolved problem of high-level nuclear waste which plagues the entire industry worldwide, accidents notwithstanding. Coal is just plain 'bad'. It's really dirty and our coal still remaining for exploitation is becoming increasingly costly to get at and move around. It is also filled with sulphur, toxic heavy metals and contaminants. So coal as a medium- or long-term energy solution, to be blunt, is not only 'bad', it's also just plain senseless. It will, in short order, become increasingly cost-ineffective and you don't need to be an actuarial scientist or statistical economist to work that out. That's the direct economic downside, let alone counting the enormous eco-cost of a coal-fired future. So what's the alternative? The answer, as we have said in the past, is the sun. There are large swathes of this country – right across the Karoo and into the Drakensburg – where we have 320+ days of full sunshine a year. There are large sections of the western and north-western areas of the country which are semi-desert and which receive even more sunshine than that – around 340-345 days of full sunshine each year on average. While huge strides have been made in photovoltaic (PV) energy-production, it is still expensive, relatively speaking, and difficult to build in large scale. So PV will play a role but more as a fill-in and add-on, than a base-load contributor. And, say critics, what happens on cloudy days? The answer to that is that on such days the wind is inevitably blowing (in those parts of the country where the sun shines the greater portion of the year). So wind-power has a role to play filling in where PV can't contribute. That still leaves us short of base-load power supply. But there is an answer for that too – and it's still the sun. The key in the last few years has been the breakthrough in concentrated solar power (CSP), of which there are three facilities either in development or awaiting construction in this part of the world. Many people, when they talk about solar, are thinking primarily of solar water heaters and/or PV. CSP is a newish idea in this part of the world – indeed, anywhere. But in Seville in Spain, two CSP plants are up and operating. One, a trough array, with much-reduced building costs and rapid construction time, is routinely producing 24 hours worth of energy from 12 hours worth of sunshine. The energy supply debate is bound to go on for some time, but we are confident that a combination of continuing development in the CSP arena particularly, in combo with progress on other renewable fronts, might not only kick the nuclear option into permanent touch, but also the coal option along with it. If nothing else, the economics of our power needs and their costs in kW/h terms may eventually win the day with a sensible and long-term, sustainable and low-cost, low-carbon future energy supply mix emerging.
So, in this our fifth digital issue, we revisit the 'sun is the answer' conclusion we have long since already reached – and which was well received when in late 2011 our title was widely distributed among global delegates at the COP17 climate conference in Durban. Also in this edition we look at the sudden surge in electric vehicles and at other mobility options which may be more ‘conventional' in terms of energy source (hydrocarbon fuels) but highly innovative in terms of consumption, emissions and overall efficiency. Another major feature of this issue is a focus on clean-ups and recycling, both as specific initiatives in the month of September, but also in an ongoing way that will help reduce the amount of junk floating around in our rivers, dams and oceans. The aftermath of the Fukushima disaster Recycling also contributes to building a secondary value stream utilising the – an ongoing testament to the danger and embedded value of a wide range of things, especially those made of plastic but also unpredictability of nuclear power. including paper, glass and aluminium, which many people still don't realise can be converted into profitable businesses, producing useful products and providing much-needed jobs. Between these features, we have a look at another carbon-based hi-tech material, carbyne, which like its cousin graphene (see Simply Green, Issue 1, 2013, pages 23-28) is set to change our technology as much as semiconductors and carbon fibres have done, or more. We have our usual range of business and consumer tips and hints for greener living, like vertical gardening, and selections from our broad palette of topics on how to live more sustainably on this one and only planet which we call home. Read, enjoy – and remember that Simply Green is free to everyone, so share, share, share. Without the information that we and our partners carry, we will not be able to empower ourselves and one another sufficiently to make the changes to the way we live, and do business, in time to avoid the worst and looming prospects of an unsustainable way of being.

Nests for humans

The Tree Shrew addict
The pen-tailed tree-shrew (Ptilocercus lowii) spends its days sleeping, but by night, this little creature indulges its taste for naturally fermented palm wine – a lot of it. In fact, booze is pretty much what they live on. So what can we learn from them and many fruit-eaters like bats and birds? They spend several hours each night sipping the equivalent of up to 12 glasses of wine. They are the only known wild mammal with such a regular drinking habit. Their drink of choice is served in the tops of the Southeast Asian bertram palm. A rich yeast community flourishes in the flowers of this palm, producing a heady brew of fermented nectar. With up to 3.8% alcohol content, the palm wine is one of the most alcohol-rich foods found in the wild. It seems that the wine is made especially for the tree-shrew, which finds itself unable to resist the opportunity to pollinate the palm. The flowers ferment all year round, and the treetop bar never closes. Madame Tree-Shrew’s rich source of calories allows her to nurse her young somewhat infrequently, and once the babies are full and drowsy, mom leaves them alone in the nest for up to two days while she goes on her next bender. It seems they metabolise the alcohol differently than we do, neutralising its effect. Which is probably a good thing. Wandering alone drunkenly through the nighttime trees would be a poor choice for such a delectable morsel, if not for this useful adaptation.

Mangrove forest reclaims coal ship
Artists, designers, filmmakers, and writers often imagine what a post-apocalyptic world will look like – and we think this wrecked ship offers a hopeful clue. Originally built in 1911, the SS Ayrfield had many functions before it was decommissioned in the '70s, but now it sits in Sydney’s Homebush Bay, where it is protected by heritage laws – and a mini mangrove forest has reclaimed it as its own. The floating mangrove forest is a key attraction at this site near Olympic Park.
Hungary destroys GMO corn fields
Hungary has taken a bold stand against biotech giant Monsanto and genetic modification by destroying 1 000 acres of maize found to have been grown with GM seeds, according to Hungary deputy state secretary of the Ministry of Rural Development, Lajos Bognar. Unlike some EU countries, Hungary is a nation where GM seeds are banned. In a similar stance against GM ingredients, Peru has also passed a 10 year ban on GM foods.

Choose your weapon – squirt gun, Evian spray bottle, wet sponge, paintbrush or even a bucket of water. All of these tools can be used to paint on Water Light Graffiti - a new interactive LED installation by Antonin Fourneau in Poitiers, France. Working in collaboration with Parisian Digitalarti Artlab, Fourneau experimented to create a wall of LEDs that lights up when hit with water. The result is an addictive night-time art installation that is totally legal (unlike tagging) and fades away in a few minutes. Antonin worked for weeks in residence at Digitalarti Artlab to create the Water Light Graffiti project. The wall is made up of thousands of LED lights that were engineered to turn on when water hit them. Anything that is wet, your finger, spray bottle, brush, or water atomiser can be used to 'paint' the surface – abstract shapes and words, for example, with a result that is glowing, ephemeral and temporary.

Announcing
simply N E W o n l i ne d i r e c t o r y FREQUENCY The Simply Green Online Directory will be a digimag that goes out once a month alongside Simply Green digimag, beginning with our next edition, Issue 6, 2013.
WHAT WILL IT LOOK LIKE? The Simply Green Online Directory will be filled with short descriptive editorials, business listings and all the usual directory entries. This will replace the directories section in the actual digimag. It will be independent (freely available on Issuu.com) but regularly promoted, and cross-referenced, in our digimag as well as promoted through our regular mailers and website.
HOW IT WORKS You can enter your details under one of the separate categories – click on each category for full alphabetical list of options – which will be continuously expanded: Babies and Children, Business Services, Causes to Support, Eco Homes and Buildings, Ethical Economy, Gardening, Growing, Greening, Green Lifestyle, Green Transport, Holidays and Recreation, Kindred Spirits, Media, Information, Events, Organic Body Care & Health, Organic Food and Drink.
EVENTS Events-related matters – will now appear exclusively in the front of the Simply Green digimag. We will charge R7.50 ex Vat per word, with a minimum of 20 words, including a free image or logo. Classified advertisers can have the option of being in the Simply Green digimag, the Online Directory or both. Email or call below for rates.
WHAT IT ENTAILS Online Directory details Advertisers need to commit to a minimum of a 6 month period. Changes can be made on a monthly basis – if need be. Payment must be upfront or in two parts – one upfront and one in the next three months – as and when agreed to beforehand. We will use a standard template; which means that clients supply us with 50-60 words for R100 ex Vat per month. Logo or image for free. We do not create or source images – material has to be complete and correct when supplied. We do not edit – no revisions allowed after submission. If you choose, your directories entry can have live hyperlinks. If we do an article on solar water heaters in the Simply Green digimag, for example, then the solar water heater suppliers listings will be in the online directory and strongly cross-referenced and promoted.

BUILDING THE WORLD OF TOMORROW
Welcome to our city. We look forward to explaining what we have done to make cities more attractive. In Sustainia, we know that successful cities generate economic prosperity and an improved quality of life for their citizens31. Sustainia is the urban age. The world’s cities – from capitals and metropolises to new, innovative urban areas and old, cultural epicenters – are home to the majority of the global population, and have regained their historic role as drivers of economic progress. They are the champions of the low-carbon age, platforms for
experiments,
innovation,
and
systemic
solutions. Cities are innovative production hubs; as metropolitan engines, they drive economic growth32. Cities are, by many measures, greener than suburbs. City dwellers produce much less CO2 than their suburban counterparts. They live closer to work and to each other, and are more likely to use public transport. And many people love living in the city. The cultural diversity and endless possibilities in cities has attracted billions of people in recent decades. Cities offer better access to jobs, education, sanitation, health care, recreation, and social mobility33. Cities attract young people seeking to learn, artists looking to perform, and migrants looking for work. In this chapter, we share

arguments for change In the past, cities grew too quickly, and were simply not able to sustain themselves. Something had to be done. Pollution increased with population. In Mumbai, for example, breathing the air was the same as smoking 2½ packets of cigarettes a day34. Had changes not been made, demand for resources would have outstripped supply as cities added evermore inhabitants. In 1900, 11 cities were home to more than 1mn residents; in 2020, there are 600 such cities35. The number is sure to rise.

More people now live in cities than in rural areas. As more people migrate to urban centers, the role of cities on the global agenda increases. Urbanisation is not bad if done sustainably – when cities grow, so does GDP. Every time the share of people living in cities increases by 10%, GDP in the country increases by 30%36. In Sustainia, we have come a long way in making cities more sustainable. By reducing pollution, we have reduced healthcare costs; by improving

By retrofitting our lovely cities, we have improved the quality of life for citizens, reduced negative enviro-impacts, and saved money. Another bonus is one that mayors often stress: Retrofitting cities creates jobs. Here is what we have done to make cities in Sustainia more attractive and sustainable: 1.

carbyne nanomaterial A new research paper published on Arxiv describes in detail the properties of carbyne, a supermaterial that is stronger than graphene (which we covered in Simply Green, Issue 1, 2013) and diamond, which can be synthesised and stabilised at room temperature. Carbyne is stiffer than anything that scientists have seen before, and it could potentially have a wide variety of applications in nanotech applications and electro-mechanical devices. We report.

It’s torsional stiffness can be zero but can be ‘switched on’ by appropriate functional groups at the ends, according to the paper. Carbyne could have an impressively wide application.

Tesla Model S Beats Crash Tests to Achieve Highest NHTSA Safety Rating of Any Car Ever Tested After a series of crash tests the US National Highway Traffic Safety Administration recently awarded the Tesla Model S with the highest safety score of any car ever tested. The electric vehicle fared exceptionally well in a range of crash situations, and it even broke the testing gear at an independent testing facility. The NHTSA's overall 'Vehicle Safety Score' for the Model S is a new record of 5.4 stars. Of all vehicles tested, including every vehicle approved for sale in the US, the Model S set a new record for the lowest likelihood of injury to occupants. The NHTSA safety rating takes into account the probability of injury from front, side, rear and rollover accidents. Some of the reasons that the Model S was able to achieve such a high rating are due to its electric car platform. The lack of an engine in the front of the vehicle, the battery pack being located below the floor and the placement of the electric motor near the rear axle helped the Tesla Model S achieve top ratings in all of the safety tests conducted.

More choices for fuel-efficient power The EcoSport will also be available with the global 1.5l four-cylinder petrol engine, which delivers peak power of 82kW at 6 300rpm and peak torque of 138Nm at 4 400rpm. It uses an average of 6.5l/100km on a combined cycle. For customers who prefer diesel, the 1.5l TDCi intercooled and turbocharged diesel engine fits the bill perfectly. With power rated at 66kW at 3 750rpm, the engine also delivers an outstanding 205Nm of torque from 2 000rpm to 2 750rpm. The result is strong acceleration from standstill together with the flexibility that can reduce the need for gearshifts. Fuel efficiency is a standout feature with this model which boasts a combined cycle figure of just 4.6l/100km ensuring the EcoSport is kind on the pocket. To further improve fuel efficiency, the five-speed manual transmission is standard on all models bar the 1.5l Petrol Titanium, which utilises the six-speed Ford PowerShift transmission. The advanced six-speed PowerShift transmission combines the efficiency, optimised gear ratios and responsive performance of a traditional manual

Unlike passenger sedans, an SUV does not naturally lend itself to an aerodynamic shape. That's why the design and engineering teams spent a year and a half shaping the body of the EcoSport to make it more efficient when slicing through the air.
Safety & driver assistance The EcoSport has been designed to provide high levels of protection and driver support through a range of advanced features. About half of the urban SUV's body structure is made up of high-strength
steel and ultra-high-strength steel, such as boron steel, making the EcoSport's frame especially strong yet lightweight too. The SUV's array of airbags include protection for the driver and front passenger, as well as side airbags and curtain airbags. To take the stress out of driving, the EcoSport comes with an array of driver-assist systems. Anti-Lock Brake System (ABS) is available on all models helps prevent the wheels from locking up and helps the vehicle to stop quickly on slippery road surfaces. Other advanced safety technologies such as Electronic Stability Control, which is available on some high-series models, also helps customers remain in control at all times, especially on slippery roads. When it detects that the car is potentially losing control, it automatically reduces engine power and selectively brakes individual wheels to stabilise the vehicle and keep it travelling on track. 'The

Toyota's Yaris Hybrid-R
To say that the Yaris Hybrid-R looks different from its bread-and-butter siblings is an understatement. This radical concept adopts newly designed headlights, a wider front grille and black and blue details that contrast with the white body colour. The front bumper incorporates two large air intakes and blue LED daytime running lights. The intakes greatly contribute to the front brake cooling, while the shape of the lower lip is designed to centrally channel underbody air flow. The flared fenders house bespoke 18-inch TRD wheels fitted with 225/40 R18 Michelin Pilot Sport Cup tyres featuring an asymmetrical tread design that is ideally suited for mixed use on the road and on the track. Grooved and perforated brake discs are gripped by six-piston callipers in the front and four-piston callipers in the rear. Located on the rear pillar, a quick-opening fuel cap allows for quick refuelling in the pits. At the rear, a spoiler is mounted on the roof and the bumper incorporates a large diffuser with an exhaust pipe framed by two air extractors. Matching the colours outside, the dual-tone Recaro bucket seats feature black leather side bolsters and blue Alcantara. Ideally located high and close to the driver's right hand, the shift lever of the sequential gearbox is set up to quickly change down gears by pushing the lever forwards, and to change up by pulling it back. The driving position is completed by a set of sport pedals from the 86 sports coupÊ. Here are some of the Yaris Hybrid-R Concept’s more salient performance features: The car's hybrid powertrain combines a highly tuned 1.6l four-cylinder turbo engine and two powerful electric motors to provide total output of 313kW. The Yaris Hybrid-R driver can push a button on the steering wheel to select 'road' mode for day-to-day driving or 'track' mode for competition. 'Track' mode makes full use of available performance, with the rear electric motors able to reach a combined maximum power peak of 90kW for up to five seconds. A third 45kW electric motor, located between the engine and the six-gear sequential transmission, can operate as an advanced traction-control system.

Lexus unveils LF-NX SUV Concept
Lexus debuts the LF-NX compact crossover concept at the 2013 Frankfurt Motor Show, 10-22 September. Powered by Lexus' unique hybrid powertrain technology, the LF-NX delivers a mix of power and economy while being tuned for SUV performance. The LF-NX concept's exterior design reflects a further evolution of the Lexus L-finesse design language – with highly sculpted exterior panels and a powerful, low stance. The front is dominated by the now signature Lexus spindle grille and arrowhead independent Daytime Running Lights (DRLs), while unique corner styling separates the bumper from the front wing with an aggressive vertical cut. In profile, the LF-NX features a pronounced diamond-shaped belt line, while the glasshouse creates a coupé-like silhouette. Rounding out the profile are muscular black-trimmed wheel arches. The rear features stylised lamp clusters that are detailed to project downwards to the full depth of the bumper, creating a sharp, aerodynamic trailing edge. The Lexus LF-NX concept is finished in a new brushed metal silver exterior colour which gives the striking impression that the body shell has been carved from a solid piece of metal. The interior mirrors the LF-NX's highly detailed exterior with bold, powerful forms creating a driver-focused cockpit within an ergonomic environment. In a continuation of the 'Human Oriented' L-finesse design concept, the cabin dash is divided into an upper display zone and lower operation zone – a design honed over successive Lexus generations. The design allows for intuitive interaction with the vehicle's next generation technology, which includes touch-sensitive electrostatic switches, and a new touch pad Remote Touch Interface (RTI) design. Reinforcing the LF-NX crossover credentials, the strength and refinement of the interior's carved metal surfacing is complemented throughout by sunrise yellow/black leather accented upholstery with contrast stitching, and sophisticated blue instrument lighting.

The sudden rise in food prices over recent years has significantly impacted on the food security of millions of vulnerable people across the globe. The FAO (Food and Agriculture Organisation of the United Nations) estimates that the recent rise in global food prices has negatively affected at least 3 billion people worldwide and has forced over 100 million people below the poverty line, with serious implications for nutritional well-being, economic stability, political security, as well as a host of other humanitarian and developmental challenges.

N ews Solar power accounted for 100% of new energy on US grid, RECENTLY According to the latest data from the US Federal Energy Regulatory Commission (FERC), March 2013 was a very special month for the US power grid. For the first time ever, all of the new capacity added during the month came from solar power. Granted, it wasn't quite an ordinary month for the grid: no other sources added any capacity, and solar officially grew by 44mW, a respectable amount for a single month (that's more than half a gigawatt annualised). Since 2008, the amount of solar energy powering US homes, businesses and military bases has grown by more than 600% according to the Solar Energy Industries Association. In 2012 alone, the US brought more new solar capacity online than in the three prior years combined, underscoring projections that solar will be the nation's largest new source of energy over the next four years.
Fluorescent dye boosts solar cell efficiency
Yale researchers recently discovered a way to boost the efficiency of solar cells by a whopping 38% by coating them with a fluorescent dye. Polymer solar cells are popular for their low cost, low weight, large area and mechanical flexibility, according to Physorg, but they only convert roughly 50% of the solar energy absorbed into usable electricity. The organic squaraine dye improves light absorption and recycles electrons, thereby hastening the light-to-energy conversion process.
Solar costs headed for parity with coal & gas
Since '75, there have been a number of significant solar efficiency breakthroughs which shows just how much progress has been made in all the various types of solar cells. But what truly matters in the end is how much it costs to produce clean electricity from the sun, and how that compares to the price of dirty sources like coal and gas. The graph above tells the tale. Since the early 1980s, solar went from over $16/ Watt (in constant 2012 dollars) to about $1/Watt, and, like Moore's Law for micro-electronics, there's no indication that the pace is slowing down. In fact, as you can see in the graph above, it has actually accelerated in recent years (in good part due to massive solar investments in China). We may or may not keep that new rate of progress, but what is certain is that we're headed for parity with fossil fuels (the gray area in the graph), and then solar will beat them on a cost per unit of production basis.

SOLARWORLD POWERS TIMBERLEA FARMING TRUST
SolarWorld Africa, together with its distribution partner enerGWorx supplied a 127kW, roof-mounted solar system to Timberlea Farming Trust, a group most well-known internationally for their blueJay branded fruit, as well as its production of the much-loved locally distributed blueJay fresh juices. The group, comprised of nine farms across the Western Cape, produces in the region of 13 000 tons of stone, pome and citrus fruit per annum and are suppliers to well-known local retailers Woolworths as well as Marks & Spencer’s, Sainsbury’s and Waitrose internationally. The farming consortium which trades under the brand, blueJay, has made considerable upgrades to their infrastructure as part of a firm commitment to sustainable business. In an effort to reduce energy consumption and save costs across all of their agricultural assets, Timberlea Farming Trust opted for the solar system installation at their farm just outside Stellenbosch. SolarWorld supplied its polycrystalline solar panels for the array spanning the multiple rooftops of the farm’s cold storage and packhouse facilities. The installation is expected to subsidise 30% of the farm’s total electrical output. 'The blueJay Group is already involved in a number of empowering initiatives for its stakeholders, from staff equity ownership to providing education for the children of staff. We are proud to add to their sustainability approach, enabling them to meet their ambitious environmental and commercial targets through the use of solar energy,' says Gregor Küpper, SolarWorld Africa Managing Director. Apart from subsidising its electricity bill quite significantly, Timberlea Farming Trust is also able to fix the costs of the electricity generated by the solar installation and address a growing demand by end consumers for products with a lowered carbon footprint. Through this 127kW installation, Timberlea Farming Trust saves 213 tons of carbon per annum.

Despite the long and dark winter, solar panels keep lining Germany’s residential rooftops. According to SMA Solar Technology, the country has just set another world record in solar energy production. Its solar power output climbed from already impressive record of 22.4gW in June to a whopping 23.9gW during peak times yesterday. The data is based on the output of thousands of SMA solar power system spread across the country. SMA’s interactive PV performance monitoring tool shows that Germany’s photovoltaic electricity production hit a record 23.4gW on June 6 and with a full 0.5gW increase peaked yesterday at 23.9gW. The massive solar electricity output is attributed to approximately 1.3-1.4 million solar power systems installed across the country, with about 8.5 million people living in buildings which incorporate solar systems to produce electricity. Germany has been the world’s solar power leader for some time now, although Bulgaria and the Czech Republic take the lead concerning solar power per GDP. According to the Federal Network Agency, Germany installed a total of 33.5gW of PV by the end of April 2013. The record-breaking amount of solar power shows one of the world’s leading industrial nations was able to produce impressive amounts of clean energy through a simple, strong policy and feed-in tariff incentives for stimulating solar power installation on private homes and businesses.
Greenpeace COMMENDS Gauteng Provincial Government
spinach nearly triples efficiency OF solar panels
Scientists in Tennessee discovered that combining spinach with silicon produced a much stronger electrical current in solar cells than present methods, and it could eventually lead to a much more efficient form of using the sun’s rays for sustainable energy in the future. A team of biomolecular engineers and chemists from Vanderbilt University in Tennessee used the photosynthetic protein in spinach – the vital ingredient that converts light into energy to make plants grow. They then combined it with silicon, which is already used in solar cells, in a way that produced an electrical current 2.5 times more powerful that existing solar cells. The team reported their findings to the journal Advanced Materials and have now applied for a patent for their process. Lead researcher, chemistry professor David Cliffel, said the new discovery could lead to the production of a new wave of solar cells within three years. Previous experiments had them using the photosynthetic protein (PS1) of plants, the team also reckon to have found a way of making the combination last for much longer with no decline in performance. Cliffel said: 'Nature knows how to do this extremely well. In evergreen trees, for example, PS1 lasts for years. We just have to figure out how to do it ourselves.' To build their cell, the protein was extracted from spinach into an aqueous solution and poured onto the surface of a specially treated wafer of silicon.This was then put into a vacuum chamber so the water in the solution evaporated but left behind the protein as a tiny, thin, film on the wafer. The protein, when exposed to light, absorbs the energy contained within the light (photons). These free electrons huddle together and create an area of positive charge which is the electrical current produced by solar cells. The process increases the amount of energy produced by the cells but researchers believe there is yet more energy that could be produced by the protein and are working to try and improve it further.
Reacting to the recent announcement of an R11bn investment in solar energy by the Gauteng provincial government, Greenpeace climate and energy campaigner Ruth Mhlanga has said: 'The decision by the provincial government to invest in renewable energy is a step in the right direction and needs to be backed by greater commitment at the national level in order to reassure investors and increase electricity access to the poor. Greenpeace strongly recommends clear and supportive legislation for small-scale renewable energy to support a roof-top revolution in the country.' Greater renewable energy investments are required to protect the environment and provide the energy security South Africans need.
Brazil's Mineirão Stadium unveils new solar roof

As the tournament approaches in just under a year (tickets are already on sale), officials recently cut the ribbon on the Minas Gerais stadium’s newly minted array, which ushers in an era of greener World Cup events. The stadium joins Mané Garrincha stadium, which will have a 2.5mW solar array that will provide enough solar energy to power nearly half of the stadium.
N ews Australian & Japanese Researchers Develop Non-Toxic Solar Panels
Solar panels provide one of the cleanest forms of green energy by converting sunlight into electricity, but the photovoltaic panels we use are made with toxic elements including cadmium and lead elements. Researchers from Australia and Japan are now working together to advance the next generation of non-toxic solar panels. The new RMIT University-led research collaboration is working to develop cheaper and less toxic solar cells using nanotech. In a mission to create non-toxic, printable nanocrystals the team of researchers from RMIT, CSIRO, and the Japan Science and Technology Agency have been trying to incorporate elements like copper and antimony – two elements that have low-toxicity and are abundant according to the researchers. In the course of the research, the team discovered it could synthesise tetrahedrite and famatinite copper antimony sulphide into nanocrystals. The resulting nanocrystals have a brown-blackish color that has a strong absorption rate of visible and near-infrared light. 'The focus of photovoltaic industries has been to reduce material and production costs for PV panels,' Professor Yasuhiro Tachibana, from RMIT’s School of Aerospace, said in a statement. 'Research into next generation solar cells concentrates on developing novel low-cost and low-toxicity colloidal nanomaterials in order to meet industry requirements.' Best of all, these new lower toxicity semiconductor nanocrystal inks can be cheaply printed into thin nanocrystal films. And the team has already confirmed the nanocrystalline film generates electricity under light, making it suitable as a future light absorber in solar cells.

How Nuroof Cool Works The sun’s radiation is made up of ultra violet light, visible light and invisible infra-red wavelengths. Roof surfaces capture enormous amounts of the sun’s energy because of their large surface area and angle of exposure. Nuroof Cool’s Enviroshield™ formulation reflects at least 30% of the invisible infra-red light off the roof’s surface, resulting in cooler roof surfaces.
TM
Reflecting the sun’s energy keeps the roof surface cooler.
Lower roof temperatures translate into cooler interior spaces – less air conditioning and potential lower energy consumption or increased comfort. The sun’s heating energy is scattered harmlessly back into space through the greenhouse gases – helping our planet stay cool.

Energy-efficient water heating solutions require us to weigh up the options. With your electrical element geyser, the biggest consumer of electricity in your home, and responsible for 30-50% of your energy cost, hot water is expensive and can account for up to R500 of a monthly energy bill of R1 000. But if you are financially savvy, this doesn't have to be the case. A solar water heating system can cut your electricity costs by up to 24%, while heat pumps can be up to three times more energy-efficient than electrical element geysers.

And such water heating systems should also be installed as close as possible to the source where the heated water will be needed.
How they work Heat pumps work on the same principle as an air-conditioner, but in reverse. Heat from air that
The gas is compressed (put under increased pressure) which causes its temperature to rise. The hot gas moves through a heat exchange device, depending on the type of system that is used. The two systems are: 'Split heat pump', where the heat exchange device is inside the heat pump; cold water from a separate water storage tank (like the geyser) is heated in the heat exchanger and transported to the tank. The water does not mix with the refrigerant as they are in two separate loops; 'Integrated heat pump', where the heat exchanger is in the form of tubes wrapped around the outside of the water storage tank – unlike the 'split heat pump', this system is equipped with a water storage tank. As a result of either system's functioning is that cool air – as a by-product – is released into the atmosphere by a heat pump fan; and it is only released when the heat pump is in operation. The temperature of the gas then drops because it has transferred its heat to the water. As the gas continues on its journey, passing through an 'expansion device', it returns to liquid form. This cycle is repeated continuously until the water in the storage tank has reached the set temperature. Solar technology is somewhat more advanced – it captures the sun's energy and transfers it efficiently to heat water. Pressurised systems have back-up elements that heat the water during

inclement weather, while low-pressure systems are ideal for unsophisticated plumbing installations and have no back-up elements. Two types of systems are available – active and passive: Active systems: electrical pumps and controls move water around the system; the two main categories of active systems are 'direct', where water moves through solar collectors, gets heated, and collects in a storage tank with the help of electrical pumps and controls; and 'indirect', where instead of heating water, the solar collectors heat a 'heat transfer' fluid. The water picks up the heat from the fluid (but never mixes with it), and gets pumped into a storage tank. Passive systems: Nothing is used but the forces of nature. There are two main categories of passive systems, 'batch' and 'thermo-siphon'. Batch is where a storage tank is situated inside the solar collector – the water gets heated inside the tank, and either gravity or natural convection moves water from the tank to your home's pipes. 'Thermo-siphon' refers to a system whereby the storage tank is separate from the solar collector. Cold water moves through the tubes of the solar

options: solar water heating and heat pumps.
SOLAR WATER HEATING Water heating using a traditional geyser powered by Eskom is costly. In an average single geyser home, water heating alone can make up roughly half your total electricity bill. If a house has two or more geysers this comprises most of your electricity bill.
Cost breakdown for the average home Installing a solar water heating system will, in one fell swoop, virtually eliminate your hot water bill, and halve your total electricity bill. If your home has more than one geyser, savings can be even more dramatic. Payback period is around two years and improving with each Eskom increase. Thereafter for the next 15 to 20 years your hot water will be virtually free. (There is a small 2kW back-up element to keep the system going on those cloudy days). Key requirements for solar water heating include a flat or north-facing pitched roof with no shade. Failing this, the next option is a heat pump, discussed below. Either system immediately and dramatically reduces your hot water bill.

This is because solar geysers have much higher thermal efficiencies (more insulation), are generally more durable and are covered by the manufacturer's warranty. Aesthetically there are two installation options, one is with tank and water panels mounted on the roof and the other is to install the tank in the roof.

Global wind energy capacity grows in 2012
Earth Hour City Challenge in SA
For the first time, South African municipalities will compete with cities around the world for the title of Global Earth Hour Capital by registering their data on the carbon Cities Climate Registry, an internationally recognised reporting platform managed by ICLEI. The challenge builds on WWF’s Earth Hour campaign, which asks citizens across the world to switch off their lights for an hour in support of global efforts to mitigate climate change. The EHCC asks cities to take Earth Hour beyond the hour by demonstrating their plans and actions for low-carbon development and for increasing the use of sustainable renewable energy and energy-efficiency solutions in the future.
S G 76
The Global Wind Energy Council (GWEC) recently released its 2012 market statistics, showing continued expansion of the market, with global installed wind energy capacity increasing by 19% in 2012 to 282 000mW. Canada remains a global wind energy leader as it experienced the 9th largest increase in installed capacity in 2012 (936mW). Both China and the US, the world's wind energy leaders, installed more than 13 000mW of new capacity in 2012.
World's 1 st Wave-Powered Desalination Plant
Carnegie Wave Energy (Australia) will be using its CETO (Greek ocean goddess) technology in this project. The 2mW pilot project will operate with multiple submerged buoys tethered to pumps that funnel pressurised water to turbines onshore. There the water can either be harnessed to create electricity or to run and supply water for a reverse osmosis desalination plant.

First Few Days backpack
When disaster strikes water sources are often contaminated and the electric grid is down, meaning no clean water and no power. To get by until relief arrives, victims need drinkable water and a little bit of electricity to recharge phones, flashlights and other small devices like radios. First Few Days (FFD) is a Singapore-based concept humanitarian backpack that filters water and charges small devices with a pumping action. The backpack allows for easy portability in case victims are on the move or off helping during recovery. First Few Days is a backpack that can be worn during travel, evacuation or rescue missions and be used to filter water for drinking. Very portable, the FFD backpack is designed also for comfort and ease of use. It is intended for victims of natural disasters as well as rescue workers, volunteers and even the military. The water filtration concept was developed to include electricity generation after watching victims of Hurricane Sandy search for outlets to charge their cell phones. Worn as either a backpack or a chestpack, FFD contains a water filtration system operated with a hand-held pump. A tube with a float is placed in a water source, and a lever on the outside of the pack is pumped to move water through an activated carbon filter. Water is stored in external bottles and filled via a port on the outside of the pack. The pump action of the lever generates electricity with the help of a dynamo, which is stored in a lithium-ion battery.
Breakthrough in power density
Researchers at the University of Illinois at Urbana-Champaign have created a new lithium-ion battery that has incredible power characteristics, at least in the lab. It can be charged and discharged about 1 000 faster than current lithium-ion batteries, even beating many supercapacitors. But before we uncork the champagne and imagine driving electric cars with 2 000km of range, what's incredible about this battery is the power density. It's an important breakthrough that could help improve batteries, especially if it can be combined with other new tech to improve energy density. Or maybe this type of battery can be used in parallel with more energy-dense batteries to offer more flexibility. Also, charging faster than the reputed Tesla's Supercharger might be hard for this technology (but not impossible).
1st pilot plant to convert CO2 into bricks
A new pilot plant recently launched in Australia aims to combat global warming by converting CO2 into bricks. The culmination of over six years’ effort by The University of Newcastle, the chemical company Orica, and GreenMag Group, the groundbreaking new facility could close carbon loops and divert the greenhouse gas from the atmosphere. The plant will be located at The University of Newcastle, and Mineral Carbonation International (MCi) is expected to spend $9m over a period of four years to establish the facility. The bricks can be used as construction materials, and they act as physical carbon sinks. Ian Smith, the chief executive of Orica, told ABC News that he believes the technology could be used by power plants across the world.

The Farming Kindergarten
S G 82
When brilliant design transforms the way children think about the playground, the entire world takes note. Perhaps this is what Vo Trong Nghia Architects had in mind when they designed The Farming Kindergarten, which is a prototype for sustainable school design where children of factory workers in Vietnam can learn how to grow their own food. Set to be complete later this year, the school building will house 500 children and feature a knot-shaped rooftop, which will be used as a vegetable garden. The roof’s surface pours into a continuous loop around three courtyard playgrounds and slopes from the ground to the peak of two stories, making an easy climb to the vegetable garden a fun adventure for teachers and their pupils. 'While these internal courtyards provide safety and comfortable playgrounds for children, the roof makes a landing to the courtyards at both sides, allowing children to enter a very special eco-friendly experience when they walk up and go through it,' say the architects. The design of the new Farming Kindergarten also presents an exploration in education – visible energy-saving architectural elements of the building design include: water recycling, solar water heating, pc-concrete louvre for shading and more, to help children see their role in sustainable and responsible living. The Vo Trong Nghia team is no stranger to receiving accolades for their innovative, and earth-friendly designs. Nghia was awarded last year at the World Architecture Festival for his naturally ventilated Binh Dunong School that made use of vertical louvres and perforated screens instead of air conditioning to keep buildings cool in the tropical weather.

World's 1st 3 D Printed Architectural Structure
Echoviren 3D-printed pavilion
WATCH THIS!
A team of California-based architects has built the world’s first architectural structure using only 3D printing technology. The 3m x 3m x 2.5m pavilion, which is named Echoviren after a special type of coastal redwood, was completed recently. Architecture studio Smith|Allen designed a total of 585 individual biodegradable plastic components which were 3D printed over the course of two months, and assembled onsite in just four days. Architects across the world have been racing to build the world’s first 3D printed architectural structure. Many of the designs, like the 'endless' Möbius-inspired house by Dutch studio Universe Architecture, are close to being built. What is different about Echoviren is the system itself – instead of using huge printers, the architects looked at aggregation as the most efficient construction system. Echoviren is located in a redwood forest at Project 387, an arts residency program near San Francisco. The designers pictured it as a structure that will integrate with the forest over time and become a micro-habitat for insects, moss and birds. In an interview for Dezeen, Bryan Allen called it 'a technological echo, a reflection, and spectre of life and of the forest'. Each of the structure’s components was made from the PLA bio-plastic that takes 30-50 years to fully decompose. The pyramidal sections make up the self-supporting circular wall that has the top part functioning as a compression ring. The pattern used for the structure was inspired by and based on cellular forms of sequoia cells, which allows for a great amount of strength while maintaining minimal volume. The team used seven of the Type A Machines Series 1 printers and worked with Ron Rael at Emerging Objects and at Berkeley to develop new materials. All attempts to build the structure using ZCorp, BFBs or Makerbots failed or were too costly. According to Allen, the Series 1 enabled the designers to 3D print large pieces reliably and at an acceptable price.

I encourage mothers to bring their little ones in as early as two and a half, just for 5-10 minutes to 'play' in the chair and get used to the sights and smells.

ynthetic household products contain harmful chemicals that react with ozone from the air, and containing toxins like formaldehyde.
According to the US Environmental Protection Agency, the inside of homes contain around two to five times more common chemical pollutants than areas outside of homes. And considering people spend around 90% of their time inside, the denser concentration of chemicals indoors is significant. It has been found that these types of pollutants can cause headaches, flu-like symptoms, neurological issues and even increase of respiratory conditions such as asthma and allergic reactions of all kinds. Just do some quick and easy research and you will be horrified at the facts, that most of these products' manufacturers would not want you to know about. It is no surprise therefore that shoppers have started reaching for so-called 'green' products, which they expect to contain significantly less amounts of these toxic substances. Many products even carry labels stating that the item is non-toxic, biodegradable, natural or organic, non-hazardous, non-flammable, and non-corrosive. These are words that require repeated defining, considering the fact that there are many natural or organic chemicals that

A natural disinfectant can be made by mixing: 4 tablespoons vinegar, two teaspoons borax, ¼ teaspoon liquid castile soap and three cups hot water. 5. Homemade cleaners for floors are also simple. To clean linoleum or vinyl, combine: 1 cup vinegar, 3 drops of baby oil and 2.5l of warm water. People can still get tough jobs done and stick to natural cleaning solutions by adding ¼ cup of borax to the floor cleaner. Wooden floors are easy to clean with a mixture of equal parts vinegar and vegetable oil. 6. Homemade cleaners for bathrooms. To clean a toilet, add 10 drops tea tree oil and three cups white vinegar into the toilet bowl and let sit for 15 minutes.

With over 20 years’ experience in the manufacture of consumer toiletry products, Earthsap applied that expertise to the manufacture of non-toxic, biodegradable, naturederived cleaners. Earthsap is formulated and tested together with their micro-biologists, and is based on pure simple ingredients including coconut, palm, citrus and other plant oils. Only pure essential oils are used, no synthetic fragrances which can be made up of over 200 different chemicals, and often cause skin irritation and allergies. Earthsap cleaners are safe for your family, pets and the environment and are completely biodegradable. They do not harm aquatic life or affect marine plant growth. Enjoy your product knowing it is good for the environment and good for you. www.earthsap.co.za
Each e-cloth has 480 000 fibres/cm2. Each tiny e-cloth fibre is split into 16 fibre strands. This is an extremely high density and means performance is exceptional. Unlike conventional cloths, as you draw an e-cloth across a surface, the fibres clean by breaking up, trapping and absorbing dirt, grease and bacteria into the material – all this with just water. No need for expensive and time-consuming chemical sprays – just move from surface to surface with a water spray in one hand an e-cloth in the other. For more info click here.

Two decades ago, a special education teacher in the US named Margery Gaffin noticed how many students were walking around with heavy, badly structured backpacks that put untold strain on their bodies and spines. Margery decided to ask her husband, a leather craftsman, to create the most comfortable bag in the world. A bag that could be worn by anyone, to go anywhere and do anything. A bag that would not give you neck-ache or a sore lower back. A bag that would be of the highest quality in terms of craftsmanship and material. Under the guidance of doctors and chiropractors, The Healthy Back Bag was born a few months later, and today it is an established brand in 26 countries around the world. Healthy Back Bags retail from R150.00 to R799.00 dependant on size and variation, and are now available in Wellness Warehouse stores and online: www.wellnesswarehouse.com.

ith 87% of the world's fish stocks either overexploited or fully fished (2012 UN's Food and Agricultural Organisation report); the state of the ocean's fish stocks is a worldwide concern. Unless action is taken, overfishing will continue to affect our marine life, livelihoods and favourite seafood choices. Woolworths has, for a number of years, shared this concern. We remain deeply committed to procuring all our seafood from sustainable fisheries and responsible farming operations and are working with local and international seafood sustainability awareness and certification programs, including the Marine Stewardship Council (MSC), the WWF-SA's Southern African Sustainable Seafood Initiative (WWF-SASSI) and the Aquaculture Stewardship Council (ASC) to ensure that all our seafood is responsibly sourced and traceable back to the ship that caught it or the farm that raised it. We are continually working to raise awareness of the issues and help our customers make informed choices.
Sustainability milestones
Since introducing our sustainable seafood policy in 2008, we have achieved a number of significant milestones, which include: 2008 – Introducing our Sustainable Seafood Policy; Becoming the first retailer to sign the WWF-SASSI Retail Charter; and we began our sustainable seafood journey by compiling Wild Caught and Aquaculture questionnaires; 2010 – Introduced random DNA testing to ensure that species are correctly identified; Stopped selling Cape Salmon as a result of depleted stock status; 2011 – Facilitated the process of getting South African farmed rainbow trout on the WWF-SASSI Green list; 2012 – Stopped selling longline Yellowfin Tuna due to sustainability concerns; Established a business-wide Fishing for the Future working group; Offered widest range of Marine Stewardship Council (MSC) certified species in South African retail; and all our seafood counters are MSC chain-of-custody certified; 2013 – Announced new time-bound retail seafood sustainability commitments.
Woolworths is committed to Fishing for the Future, and preserving seafood stocks for future generations. This is their report.

What Can You Do? When you buy responsibly sourced seafood, you're doing your part to ensure there will be plenty of fish in the sea for future generations to enjoy. Choose wisely Check for credible eco-labels when buying seafood, like the MSC blue fish-with-a-tick eco-label which indicates that the product is certified to have come from a well-managed and sustainable fishery. Check packaging information. Not only will our seafood products carry our Woolworths 'Fishing for the Future' logo as a guarantee of our commitment to responsible sourcing, but we have labelled our packs so that you can be sure the fish you are buying is what we say it is. We will also display, where we have space on pack, the SASSI FishMS number so that you can verify the sustainability status of the species you are buying.
WATCH THIS!
Check the sustainability status of the species you're buying. SMS the name of the fish you're buying to the SASSI FishMS number: 079 499 8795. You can also download a full list of Green-, Orange- and Red-listed seafood species as well as the handy consumer seafood pocket guide from the WWF-SASSI website. Choose from WWF-SASSI's Green-list when you buy seafood. The Red-listed seafood species include both illegal and over-exploited species – never buy these.

Future Commitments
Having accomplished our milestones, we have now set ourselves some equally challenging but achievable goals for the next few years:
By end 2015, all our wild-caught seafood will be: Sourced from fisheries that are undertaking a credible, time-bound improvement project*; WWF-SASSI Green-listed, or caught from MSC (or equivalent) certified fisheries.
All species produced by aquaculture will be: From aquaculture operations that are engaged in a credible, time-bound improvement project*, or, where applicable WWF-SASSI Green-listed, or formally committed to achieving the Aquaculture Stewardship Council (ASC) certification or have other credible standards in place such as Certified as Global GAP, Best Aquaculture Practise (BAP), Quality Trout UK (QTUK).
By end 2020, all aquaculture species sold will be: From aquaculture operations that are engaged in a credible, time-bound Improvement Project*, or will be WWF-SASSI Green-listed, or where applicable, are ASC** (or equivalent) certified. You can partner with us on our sustainable seafood journey. Click here to find out what you can do.

Visit www.woolworths.co.za *Woolworths, with the assistance of WWF, will determine the credibility of these Improvement Projects on a case-by-case basis and will provide guidance to fisheries/aquaculture facilities as to what constitutes a credible, time-bound improvement project. **These are source aquaculture operations for which there are relevant ASC standards to be certified against.

Our Partners Here's some more information on the local and international seafood sustainability awareness and certification programs that we're working with to ensure that all our seafood is responsibly sourced and traceable back to the ship that caught it or the farm that raised it. The Southern African Sustainable Seafood Initiative (WWF-SASSI) WWF-SASSI was launched to inform the seafood industry, from wholesalers and retailers to restauranteurs and seafood lovers, about the threats facing SA's marine ecosystems. It aims to shift consumer demands from overexploited species to more sustainable options. WWF-SASSI compiles a colour-coded list of seafood species, indicating those that are plentiful (green), those that are overexploited or illegal (red), or caught in a way that have associated enviro-concerns (orange) and encourages consumers to use this list to check the sustainability status of species.
The Marine Stewardship Council (MSC) MSC is a leading global certification and
eco-labelling program for sustainably caught seafood. Fisheries are assessed against standards by independently accredited certifiers, and products from certified fisheries carry the blue MSC eco-label as a guarantee of their sustainability. The Aquaculture Stewardship Council (ASC) The Aquaculture Stewardship Council (ASC) was co-founded by WWF and the Dutch Sustainable Trade Initiative (IDH). It aims to be the world's leading certification and labelling programme for responsibly farmed seafood. Seafood farming operations may be audited against the standards to achieve certification.

OUR FISH IS BEST ENJOYED WITH A SIDE OF SUSTAINABILITY. When you buy your fish from Woolies, you join us in working to make sure there will be fish in the sea for future generations to enjoy. We’re working with the Marine Stewardship Council (MSC) and WWFSouthern African Sustainable Seafood Initiative (WWF-SASSI) to ensure that all our seafood is responsibly sourced, and have labelled our packs so that you can be sure the fish you are buying is what we say it is. Responsible sourcing is all about asking the right questions and choosing the most sustainable option. You can check the status of seafood by SMSing the name of the fish to WWF-SASSI on 079 499 8795.

Green mustard is not as hot or as rampant as its red cousin. It is as quick to reach harvesting size, but doesn't grow as tall. Different varieties have varying leaf shapes, from flat and pointed to bright green and frilly. It can be steamed, stir fried or eaten raw. Gai lan, also known as Chinese broccoli, bears succulent buds on long, edible stalks. If you continue to cut the buds before they flower it will provide a harvest for longer. The stems add a crunchy texture to stir fries. It only needs to be cooked for a short time and is delicious with oyster sauce and garlic. Tat soi has flavoursome dark green leaves and grows in a flat rosette shape. It is very nutritious and can be eaten raw or cooked. Mizuna has a mild peppery flavour with spiky green or purple leaves. It adds texture to both the garden and a salad plate. Chinese cabbage forms a dense head with overlapping pale green and white leaves. It needs regular water and forms better heads in colder weather.

Circles of Life Simply Green's garden at this year's Garden World Spring Festival was designed by Sharon Catterick and entitled 'Circles of Life', with landscaping and construction done by Garden Girlz. Says Catterick: 'This garden was a challenge as it has a peculiar shape and had an existing patio. The goal was to show that small gardens can be beautiful and practical, without being a huge amount of work. Entertaining is a huge part of our lives, so the patio was very important and just an extension of the garden. The design is slightly retro, with the chosen colours and wallpaper. The design starts with the organic log path leading you through bursts of vibrant plant colour and small circles of manicured lawn to the patio where the circular theme is continued on the walls. The overall effect is simplistic modern and manageable for a busy couple or a small family. Gardens have become a lot smaller and we are demanding a lot more out of our small spaces. The design has to be a lot more accommodating to small spaces and using the patio as an extension is essential. Practical designs, but yet still beautiful living.'

the walls S G 128
Living walls have transformed concrete buildings and living spaces into tropical wonders the world over. A growing desire to incorporate nature into unusual and urban areas has led to a blurring of the traditional uses of space and plants are no longer confined solely to designated garden areas. With the dream of bringing lush greenery to urban spaces, we take a look at this 'creeping' trend.

ometimes called vertical gardens, green façades or bio walls, living walls are a dynamic way to green a vertically-built surface. They
refer to vegetation that grows directly onto a building's façade or to vegetation that is grown on a separate structural system that can be freestanding and adjacent or attached to the wall. Although Patrick Blanc (a botanist at the French National Centre for Scientific Research) is sometimes credited as having developed the idea of vertical gardens in the late '80s, we can trace the concept back to 600 BCE with the Hanging Gardens of Babylon, but the version we see today was actually invented by Stanley Hart White at the University of Illinois in the '30s. White holds the first known patent for a vertical garden conceptualising this new garden type as a solution to the problem that a lot of modern garden designs had, namely running out of space. The plants in vertical gardens help absorb toxins in the air, regulate moisture, reduce reflection of light and heat, and also add beauty and interest, bringing a calming effect on spaces. There are typically two main categories of green walls: green façades and living walls. Green façades are made up of climbing plants either growing directly on a wall or, more recently, specially designed supporting structures. The plant shoot system grows up the side of the building while being rooted in the ground. With a living wall, the modular panels are often made of stainless steel containers, geotextiles, irrigation systems, a growing medium and vegetation. Green walls are found most often in urban environments where the plants reduce overall temperatures of the building. A primary cause of heat build-up in cities is 'insolation' (the absorption of solar radiation by roads and buildings in the city and the storage of this heat in the building material and its subsequent re-radiation). Plant surfaces, however, as a result of transpiration, do not rise more than 4-5°C above the ambient and are sometimes cooler. Living walls may also be a means for water re-use, as the plants can purify slightly polluted water (such as greywater) by absorbing the dissolved nutrients. They are particularly suitable for cities, as they allow good use of available vertical surface areas, as well as arid regions, because the circulating water on a vertical wall is less likely to evaporate than in

Cape Town city bowl residents were treated with a dash of greenery on the busy Kloof Street with the addition of a new kind of advertising banner. Looking lusher than ever, the Emirates Air wall garden depicts the world map and was erected last year and has been growing before the Mother City’s eyes. An innovative form of advertising by Tractor Outdoor for Emirates Airlines, the wall is the first of its kind in South Africa. 'We've admired the work of French vertical garden supremo Patrick Blanc for many years,' says Simon Wall of Tractor Outdoor, 'and we had been looking at ways to erect similar gardens in Cape Town. With this concept we're able to convert normal, dreary, bland and blank façades into green, breathing spaces. We don't have to rely on traditional soil-growing methods and can effectively brighten and bring life to any wall, anywhere.' This project also supports Cape Town’s bid for World Design Capital 2014 by actively integrating art with public and private spaces.

17-year-old Cape Town student Hannah Allderman is mad about going green. Recently, she did a geography project that she designed and made with a friend. They got involved in the community, taught people about sustainable gardening and made many living walls for the community. Since they completed and handed in their project, they have continued the work, expanded it and are now making even more living walls, educating locals and taking their project further in every way possible. The accompanying pictures are just a glimpse into what they did. They have made a short film in the hope that people will see how to make these walls and what to plant in them. They would appreciate any advice or feedback, so check out the video (below)

SPIN-2-ZERO WITH FOOD & TREES FOR AFRICA Attention all cyclists – professionals and amateurs – mother nature is calling upon you! It’s time to hit those pedals and save the planet, one stride at a time! By joining the Spin-2-Zero Team your cycling will enable us to plant trees in poor communities across South Africa while offsetting your carbon footprint. Be ahead of the pack for the Momentum 94.7 Cycle Challenge. If you choose to cycle for the Spin-2-Zero Team you will be included in the charity start time and start in the front! Together we will all win by spreading awareness and responding to climate change. Once you have registered for the Momentum 94.7 Cycle Challenge, you can begin fundraising! Each cyclist will need to either raise or donate R500 to Food & Trees for Africa. Some of this money will cover the costs of your t-shirt (designed and part sponsored by Pure Imagination),a biodegradable water bottle and a certificate acknowledging the planting of your first tree. The remaining balance will go towards planting more trees for poor communities in dusty, barren townships. For more info click here.

PACKAGING Organic isn’t just a word, it’s a holistic mindset, and Afmine use 100% organic hemp bags to make sure that once you’ve used their product, other plants and animals don’t have to pay the price. Even the ink used on their bags is eco-friendly. Throw it in the ground or trash; these bags will turn into compost themselves. The bags are so durable that you could simply roll-down the edges of one and turn it into a pot for some fresh basil, baby tomatoes, spinach, chillies, or anything you like. Hemp has great properties and you may find that after washing your empty bag, it will start a brand new life. Why make a mess when there’s a 'soilution'? Overall, Afmine are committed to provide the best solutions for agricultural and gardening needs while keeping the environment’s best interests at heart. They believe in a sustainable future, but to get there, we all have to start today. See ad, right, for more.

he details of life's origins are ineffable, but soon after the first forms of life appeared on Earth, organisms must have learned to use
the premium energy of sunlight to grow and sustain themselves. Earth's atmosphere is the result of life's processes over billions of years. Photosynthesis by green plants, algae and photosynthetic bacteria removes CO2 from the
atmosphere and adds oxygen. Oxygen is a highly reactive gas that rapidly combines with many other chemical elements and so does not remain in its free form for a long time. To counteract the removal of oxygen by chemical reactions, life acts as an oxygen pump, continuously returning oxygen to the atmosphere. Free oxygen in the Earth's atmosphere is the result of three billion years of photosynthesis and is therefore a product of life. The reactions of photosynthesis take place within chloroplasts in leaf cells. In each chloroplast are pigment molecules called chlorophyll. Each chlorophyll
molecule
is
capable
of
capturing
photons, which are packets of energy. The plant converts this light energy into chemical energy in the form of glucose.
The energy used by most living cells comes ultimately from the sun, captured by plants, algae and bacteria through the process of photosynthesis. In this issue, educator Sharon Levy investigates how life is powered by sunshine.
THESIS
The
following
experiments
demonstrate
that plants need chlorophyll, light and CO2 for photosynthesis and that the plants produce oxygen and glucose (which is changed into starch) as the products of photosynthesis.
IS STARCH PRODUCED IN PHOTOSYNTHESIS? Sugars produced by photosynthesis are converted to starch for storage. So the presence of starch indicates that photosynthesis has taken place.
WHAT TO DO
Dip a leaf in boiling water for about a minute to soften it.
Put the leaf in a test tube of ethanol and stand in hot water for 10 minutes (to remove the colour).
Remove and wash the leaf. Lay the leaf flat on a white tile and add iodine. WHAT YOU HAVE DISCOVERED If starch is present, the leaf should go blue/black. If you use a variegated leaf (which has some white parts as well as green parts, you will notice that only the green parts go blue/black) which is evidence that

photosynthesis only takes place in the presence of chlorophyll.
DOES A PLANT NEED LIGHT?
The plant for testing must first be de-starched, by placing it in the dark for 1-2 days.
Cover part of the leaf with some foil and leave in the sun for a few hours.
Test the leaf for starch; only the uncovered part of the leaf will contain starch.

Leave the plants for 24 hours. Prepare one leaf from each plant by putting it in hot ethanol, rinsing it in cold water, and testing it for starch.
DID YOU KNOW?
Melvin Calvin, who unlocked the secrets of photosynthesis, discovered that plant chlorophyll under the influence of the sun's rays can give up electrons to a semiconductor such as zinc oxide thereby creating a 'green photoelement' which produced a current of about 0.1 micro-amperes/cm2. Calvin calculated that a chlorophyll photoelement with an area of ten square centimeters could yield a kilowatt of power.

Pest-free Green
For many the default response to a pest problem is to reach for the bug spray – or, in a
commercial context, call the pest control guys. The problem with both those reactions is that it's certain that the bug spray will contain harmful chemical and all but one pest control outfit operating in South Africa at present will also be using at least some potentially harmful chemicals. We take a look at being pest-free and green, all at the same time.

no planet B" – and we are rapidly polluting it to death. Our oceans, as food sources and stabilisers of our planetary eco-systems, are critical to our survival as a species. People often don't understand the linkage between casually throwing away a plastic bottle, bag or something else which eventually ends up in the oceans, causing damage and toxicity and contributing to the decline of many food species numbers, as well as a general deterioration of the oceans as a whole. 'One of the reasons that Plastics SA is so involved with this program is that plastics of various kinds have become central to the way we live in the 21st century – and around 70% of the waste picked up on our clean-up drives is made of a variety of plastics. We, who work in the plastics industry, are therefore acutely aware of both the benefits of plastics – we simply couldn't live as we do without them, and they are found in almost every sector and in almost everything we own, including our clothes. But we are also very aware of the damage that plastics can do and of their inherent value even as waste products. 'Many forms of plastics are recyclable, and have value in and of themselves, even as waste products. This is what we are educating school children, communities and the public in general about.' Steyn has become something of a hub around which the plastics industry's sustainability efforts now revolve. The local plastics industry has signed on with 57 plastics associations from around the world to the marine Debris Declaration which was instituted at the 5th International Marine Debris Conference held in Hawaii in 2011. A Global Action Team (GAT) was established to initiate worldwide activities aimed at the prevention and reduction of the impact of marine plastics with more than 100 related projects identified for action last year by 32 countries. With Steyn being one of the players in this global drive, the SA plastics industry has found itself on the GAT steering committee; once again a single individual has shown how inspiration and perspiration can combine to make for a powerful formula for change. Plastics SA has, with Steyn playing the key role, made significant strides in bringing an ever-widening group of organisations

and institutions into the clean-up program as sponsors and active participants. Within the industry itself, there are efforts to reduce waste, support clean-up day in practical ways, establish a technical and advisory panel to deal with marine litter along

SA's coasts, support and manage plastics recycling and education campaigns for educators, students and enviro-organisations, as well as encourage best practice in SA's fishing industry, and to support research activities into the status of our troubled marine environments, among other activities. That the clean-up program is working is clear from the global 2012 results which numbered a hair under 600 000 volunteers who picked up over 4.165m kgs of litter along some 33 435km of beaches.
161 S G
That having been said, Steyn is quick to add that as impressive as these numbers are – given the starting point of a single person on a Texas beach some years ago – there is as yet a great deal more to do. Every year the global plastics waste burden grows, especially as countries like China and India, with their massive populations that together come to over 2.5bn people, become ever-more developed. The same applies throughout other developing countries and especially SA where plastic waste in particular has for some time been recognised as a national scourge. His call goes out, this clean-up month, to all South Africans and to everyone anywhere else on our precious planet, to realise that we are all connected, that every eco-system depends and interacts with every other eco-system at some point, and that we simply cannot go on tossing our waste about as if it will magically go away somehow. Ideally, the end-point of a campaign to clean up our mountains, veld, cities, suburbs, rivers, dams, beaches and ocean will only be successful when there are too many volunteers trying to clean up a diminishing amount of waste. That's not likely to happen this year or next or even the one after that. But, just like the global campaign started by a single concerned person, there is no limit to how far such social initiatives can go, especially when backed by an increasingly aware and concerned collective of corporates and other organisations. We can, indeed, change the world. Working
National Recycling Day Friday 20 September this year will mark National Recycling Day. Schools, businesses and communities are encouraged to recycle that Friday – and then as much as possible every other day of the year thereafter. 'Although recycling has become second nature to many people, research shows that the majority of our population still don't recycle despite the various awareness campaigns. There are still not enough collection points in many of our major cities, while many consumers still claim to be unsure about what materials can be recycled or how to go about it,' Steyn says. 'This is one day of the year that we are making an appeal to South Africans to consciously recycle their plastics, cans, glass, paper, oil and e-waste in order to reduce the pressure on our country's landfills. Support the recycling industry by taking your recyclables to a recycling facility near you (visit www.mywaste.co.za) or by separating your recyclables from your wet waste for curbside collection. Communities should appeal to their local municipalities and leaders if they live in communities where their waste is not collected and recycled,' Steyn goes on to say.

Africa's western black rhino now extinct Africa's western black rhino is now officially extinct according the latest review of animals and plants by the world's largest conservation network. The subspecies of the black rhino -- which is classified as 'critically endangered' by the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species -- was last seen in western Africa in 2006. The IUCN warns that other rhinos could follow saying Africa's northern white rhino is 'teetering on the brink of extinction' while Asia's Javan rhino is 'making its last stand' due to continued poaching and lack of conservation. 'In the case of the western black rhino and the northern white rhino the situation could have had very different results if the suggested conservation measures had been implemented,' Simon Stuart, chair of the IUCN species survival commission said in a statement. 'These measures must be strengthened now, specifically managing habitats in order to improve performance, preventing other rhinos from fading into extinction,' Stuart added.

Paarl nursery donates 4000 trees
Based in Paarl, Just Trees is the largest wholesale tree nursery in SA. Recently, the nursery took their core competencies, as well as their passion for environmental and social entrepreneurism, to a new level by donating 4 000 trees to the Drakenstein Municipality. With a 90-95% success rate of trees planted by Albert van der Merwe, head of the Drakenstein Municipality’s Parks, Sport and Recreation and his team taking root, and carbon footprint calculations based on only 40% of trees surviving, the trees donated by Just Trees in fact doubly offset their carbon footprint – and, by association, that of the municipality too. What can’t be calculated or price-tagged however is the positive social impact the trees have on the people who receive them. The playgrounds, homes, parks, churches, NGOs, schools, spaces and streets – especially in Drakenstein’s disadvantaged communities – are not only greened and beautified but the trees provide shelter, shade, play, and, above all else, a sense of pride. Three hundred of the trees donated have already been planted in the parking lot of the Dal Josaphat stadium and will one day provide a shady car park for all members of the Paarl public to enjoy. Another 100 trees have been planted in the streets of new housing developments and, in years from now, will transform dusty sidewalks into leafy, tree-lined lanes. The remainder of the trees will be planted during Arbor Week, with Drakenstein Municipality Executive Mayor, Councillor Gesie van Deventer, kicking off the ceremony by planting trees with the community and teaching them how to care for them.
WWF graduate intern program
Nedbank is investing R2.4m to help talented young university graduates gain the skills they need to become tomorrow’s sustainability leaders who can help the country’s transition to a green economy. The investment forms part of the WWF Graduate Intern Programme (the programme) through the funding of 10 WWF Nedbank Green Trust Interns, which, according to Maseda Ratshikuni, Head of Cause Marketing at Nedbank Group, has been developed to ensure that the valuable qualifications of SA’s young graduates in the environmental and social sciences are put to the best possible use. Once all the internship positions have been filled the young graduates will undergo an intensive 18-month training and development programme where they will be exposed to both office and field work under the mentorship of leading experts in their respective fields.
Shell vs the Arctic
Recenty, millions of people around the globe watched live, when Greenpeace exposed Shell's dirty Arctic drilling plans in the most public way possible at its biggest sponsor event of the year: the Formula 1 Shell Belgian Grand Prix. 'We've got the world's attention, but we need to show there's real people power behind this action. Add your name now to stop Shell from drilling in the Arctic. Arctic ice is melting fast, and polar bears are starving to death as their habitat disappears. Shell is leading the insane race to drill for the fuels that caused the melting in the first place, putting this uniquely vulnerable region in grave danger. Shell was hoping to ride on the glory of the racing drivers and pretend it's worthy of a spot on the podium. We took action to make sure the truth of Shell's shady Arctic oil business gets out – and to stop them from getting away with it. By sponsoring an event like Formula 1, known for its cutting edge engineering and innovation, Shell is hoping to draw attention away from its disaster-prone Arctic drilling program and total lack of experience operating in some of the most extreme conditions on Earth. Our campaign to save the Arctic continues on land and at sea. Right now the Greenpeace ship Arctic Sunrise is being forced out of Russian Arctic waters by the Russian Coast Guard because they don't want us bearing witness and taking action against the reckless oil companies racing to drill there. We are doing everything we can to make sure no oil spills pollute the pristine Arctic this year,' says Greenpeace. Visit here to support.
Teen invents device to retrieve ocean plastic
Boyan Slat, a 19 year-old Dutch inventor, has invented a way to collect +-20bn tons of plastic from the oceans in a few years. His invention is called the Ocean Cleanup Array, a platform that would use a series of floating booms and processing platforms anchored to the seabed to suck plastic from the seas like a giant funnel, leaving marine life behind. The platform is thought to be self-powered by clean energy from the sun and the ocean. Slat and his friend came up with the idea during their last year of secondary education where they performed experiments on concentration of particles, separation of plastic from plankton and on plastic depth measurement devices.

Beyond Smoke and Mirrors: Climate Change and Energy in the 21st Century Burton Richter Cambridge University Press • 978 0 5217 4781 3 Although written by a professor of physics and published by CUP, this one is meant to be readable by all interested parties, from concerned citizens through to corporate and government leaders. There's plenty of science behind the clear, straightforward writing – and there's very little axe-grinding or polemical argumentation. But the author does reveal a good deal about the various fallacies doing the rounds, both in the camp of the anti-greens, as Richter calls them, and the ultra-greens, who he says are proclaiming a global emergency to be dealt with at any cost and immediately. Starting with the anti-greens, Richter dissects their arguments (and, as he points out, hardly anyone with a brain cell to spare still tries to argue that global warming and climate change aren't real), showing them devoid of scientific support worthy of the name, or even any real logic. How, for example, can people admit that the greenhouse gas effect is real, that the planet is warming up and then not make a connection to our increasingly volatile, unpredictable and extreme weather patterns as an expression of planetary climate change? It's beyond the author of that book and ourselves, yet some people adamantly hold to this irrational position. On the other end of the spectrum, we have the ultra-greens, some of whose near-term predictions the author says are exaggerated not in terms of how bad things will get (if, for instance, the planet warms to around 6°C, as it likely will if we do not begin to deeply cut back on GHG emissions like CO2, and quickly at that), but how soon all this will take place. The planet isn't likely to become several degrees warmer on average in the next few years and so the ultra-greens are doing themselves and their cause a disservice, he argues, by such exaggeration. He carefully analyses current and potential future sources of energy and energy production, as well as ways to mitigate what we've already more or less irreversibly done to the climate in terms of what seems likely to happen by the end of the 21st century. He also looks at governmental and international aspects of dealing with the set of issues now confronting us. Our only issue with this author is that, if anything, he steers closer to the anti-greens than is wise in terms of timing around global climate change. The point here is that an average 1°C warming does not express itself equally everywhere – and even though relatively recently written (2010), this book is already slightly dated because some of the changes the author expects to see years out from now are already with us just a few years after his book was printed. If you want to know what's going on, in real terms and based on solid evidence, this is a key book. The only warning – and it's a pretty big one – is that if a scientist as close to the subject as this author is can be out of date on key issues such as the speed of ice cap loss in places like Greenland after just a few years, how much quicker will what he predicts be upon us? The answer seems to be sooner than later, in which case the arguments of his 'ultra-greens' may be rather more uncomfortably true, or at least will be true sooner, than this author and many others believe. And if you know a climate change denialist, do everyone a favour and buy this book, read it and pass it on to them, because with silencing of the naysayers, something might get done sooner than later, and that's really what's the bottom line for every human being.

This is indeed the story of a dream as the subtitle declares. It is the dream of a man who has a deep passion for farming and living close to and off the land. It is personal, touching, inspiring and deeply revealing of the thinking and attitudes of someone who simply loves what farming is all about – the animals, the land and the relationships of the people who live on it, to the greater forces of nature on which they depend and which in effect rule their lives. It's a good read, well enough written to be easy to consume and will perhaps engage many a townie with some of the more (and some of the less) appealing aspects of this type of lifestyle. For all those urban commuters stuck in traffic, stressed to the back teeth and dreaming of a life beyond the madding crowd in the serenity of nature, they should have a good read and perhaps reconsider if they are suited for the demands and rigours of farm life before selling off and heading for the hills.

Although published locally, this book takes us on a visual tour of some great succulent gardens in various parts of the world. In a water-stressed country like SA, going the natural route and using water-wise plants is the obvious thing to do. And few plants are more water-wise than succulents. If you are into plants, and obviously succulents in particular, then this one will really be of interest. If not, there are plenty of great pictures to be enjoyed in what amounts to a great little coffee-table book with some potentially interesting and useful info between the images.
Getaway: 21 Years of African Travel Writing Edited by Cameron Ewart-Smith Jacana • 978 1 7700 9886 2 Almost every South African will be familiar with Getaway magazine which has spent 21 years regaling its readers with stories of amazing places – and often the journeys that get us to these places. There are, consequently, some real gems among the 45 features which form this book, those having been chosen from over 1 000 possible articles published in that time. If you like travel literature, and especially travel and destinations in Africa, then this one will amuse, entertain, amaze and engage you. Well worth it if you are into travel – or are looking for a fascinating getaway destination of your dreams.
An Arid Eden: A Personal Account of Conservation on the Koakoveld Gareth Owen-Smith Jonathan Ball • 978 1 8684 2363 7 This is the story, mainly of the early years in the life of conservationist Owen-Smith, back in the dark old bad days of apartheid and a very limited grasp by the authorities of that time on how conservation really ought to work. The author's then ground-breaking and revolutionary insight was that for any such enterprise to work, it must first be communitybased, or it is doomed ultimately to failure. Without the involvement, extensive buy-in and ultimately ownership of such undertakings by local communities, they literally have little to no chance of success, as many examples across Africa demonstrate. That there has been such a success in the Koakoveld lies largely with this man and his boundless energy to make happen what needed to happen, regardless of problems, official obstructionism and the many other issues with which conservation programs in Africa are fraught. Ultimately, this is a highly rewarding book because it offers an insight into how things can, and arguably should, be done right across the continent to ensure that we hand on to succeeding generations a landscape full of life and rich on in natural wonders.

It is not, for example, the fatty nodules that some people (usually women, but not exclusively) complain of and which are the subject of a great deal of time, money and trouble to get rid of. That would be cellulite. Cellulose is essentially what is left of the wood fibre when the other natural substances found in wood have been removed. It is usually found in long strings, called polymers, which is a technical term that only means that it is composed of many parts strung together. It is the most abundant natural organic polymer on earth and is found in all plant materials. Learning how to use it for a bewildering variety of modern products has been the key to unlocking a value

chain of which the great majority of people are simply unaware. In Sappi's case, their cellulose is obtained from wood from certified forests or plantations which is then processed and purified by applying specialised chemistry to extract the cellulose polymers from the wood. The purified natural wood cellulose fibres are further dissolved by other manufacturers and re-generated or reformed for a host of applications. The 'raw material' which Sappi and other pulp manufacturers produce for further conversion is called dissolving wood pulp or specialised cellulose for those in the industry. While the manufacturing of this form of wood pulp

We've looked previously at the issues around paper. Now we turn out attention to dissolving pulp, not least because Sappi, as a global player in this industry, has
involves various chemical processes, primarily the use of magnesium sulphite and calcium, this does not mean that the process itself results in major negative environmental impacts. If kept in-plant, there is no reason for significant effluent to result from the process and Sappi says it has gone out of its way to ensure that existing plants and new plants designed to produce this product do not contribute to enviro-toxicity in any meaningful way.

Process & product complexity Cellulose is an extremely versatile polymer which can be chemically converted into numerous products. However, it is a natural polymer and therefore subject to significant natural variation depending on the source. Many factors have an influence on the functionality of dissolving wood pulps, including: Wood source (softwood/ hardwood/ species; age, season, climate) Process type (chemistry of cooking and bleaching) Sheet structure (delivery package) Every dissolving wood pulp (DWP) type has unique performance characteristics based on the manufacturing 'history' of that type and a technical understanding of process influences on pulp reactivity is critical for DWP applications. Sappi says that the pulp from its largest DWP mill, Saiccor, is particularly reactive, with the expectation that the DWP produced at its recently commissioned mills, Ngodwana and Cloquet, will also have good reactivity, which makes it ideal for some end products and less so for others.

What it's used for All that info is perhaps of some relevance, but things really become interesting when we look at what the pulp all those trees have been grown to produce is used for. Indeed, you may find along most supermarket aisles one or more products using DWP. Included in this line-up would be yoghurt, toothpaste, wet-wipes, washing powder, ice cream, clothing and other apparel and a range of other items, including, weirdly, the screens on computers and cell phones, run-flat tyres and a whole spectrum of other seemingly unrelated consumer products.

applications, including making fibre garments produced from synthetic fibres, such as polyester, much more wearable by making them softer and more breathable on the skin. Although you may not usually use such synthetic fibres by preference, you are almost certain to own clothing which includes them.

So will cellulose harm you if you consume some in your ice cream, yoghurt or toothpaste (in which the pulp helps bulk out the product, keeping it stiff, not too runny and more easily handled)? The answer is no. Cellulose is completely inert as far as the human digestive system is concerned.

t is perturbing that we are embarking on a new coal fired power plant as it seems that there are different government strategies being developed
in contradication to each other. With one arm of government pushing for a low-carbon future while the other seems to be against it. 'The construction of the power station itself is reported to be estimated at a staggering R200bn which is an enormous amount to fork out given what has happened with Medupi. The public will have legitimate concerns of whether we will have a repeat of Medupi and these plants cost more than what has been originally projected,' says Fakir. 'This does not even begin to take into account the knock-on costs to the consumer or the delays in dealing with existing power plants that need to meet the requirements of higher air pollution standards.' Electricity prices have tripled over the past five years and Eskom has been given the go-ahead to increase prices by a further 8% per annum for the next five. Coal mining costs are increasing, and along with them, the cost of coal-fired power. In any case, future coal plants will have to rely on coal supplies that are less desirable – from poor quality coal in the Waterberg. Eskom has already warned of 25% cost overruns in the building of Medupi and Kusile, along with a projected 10% per year increase in the price of coal over the next five years. At the same time, renewable energy prices have fallen by 25% for solar photovoltaic power, 6.5% for concentrated solar power and 11% for wind power. Where coal costs are going up renewables are coming down. Coal-3 will, in essence, trap consumers into higher
'Cabinet's go-ahead for Coal-3 last week has been met with condemnation from various enviro-groups, but even if we set aside the extensive enviro-fallout from such a project (which would include huge water costs, air pollution and increased carbon emissions), the project makes no sense from an economic perspective,' says Saliem Fakir, Head of WWF South Africa's Living Planet Unit.

and higher electricity bills while also increasing the country's carbon emissions. 'The estimated R200bn to be used on Coal-3 could better be used to fast-track the renewable energy build program which would result in a faster increase of energy supply, resulting in immediate growth in our energy supply-base and kickstarting our economy. Furthermore, such an investment would prove cost-effective over the long term as mining costs increase. It would also reduce end costs to the consumer given that the carbon tax is likely to come through in 2015.
