Motoring - Electric Vehicles: Are they so green?

Use Locally - Issue 83 March 2020 Electric Vehicles: ARE THEY SO GREEN?

The car was designed to dissipate heat from an internal combustion engine running on fossil fuels. Made of metal construction with little insulation, certainly no double glazing with heating from the engine in the winter and air conditioning for the summer. Most will know this if you have ever sat in a car in the winter without the engine running; it soon gets cold. E-cars of any manufacture built this way are not electric vehicles (EV) but a car that has been electrified as a consequence of the manufacturer's supply chain being set up for this type of construction. Electric Vehicles on the other hand will eventually be constructed out of polymers, with insulation and most probably double glazed in order to keep the heat in in winter and cool in summer. This is because any heating or cooling drains the battery and reduces the available mileage. The new 'stress' now identified for drivers of electric cars is Range Anxiety, the stress of worrying about being able to get to the destination or home before the battery runs out. To avoid this stress the drivers 'top up' the battery at every opportunity and with as higher charge

current as possible, this is not conducive to extended battery life. Now, mobile phone users who do this soon start to notice that the usage per charge reduces - electric cars are no different except that replacement batteries are very expensive around £7000 -£10,000, significantly reducing the second hand resale value. Electric cars are greener with no CO2 emissions... or are they? The assumption that electric cars do not produce CO2 whatsoever is just wrong. By 2030 European carmakers must have achieved average vehicle emissions of just 59 grams of CO2 per km, which corresponds to fuel consumption of 2.2 litres of diesel equivalent per 100 km (107 miles per gallon). This simply will not be possible, not withstanding the recent government announcement that the government intends to prohibit petrol and diesel sale from 2035. Currently electric cars emit a substantial amount of CO2 not from the car but from the gas/coal powered generating plant from which they are indirectly connected. Solar/wind power generation is only effective when the wind blows and the sun shines, coal or gas powered power

Use Locally - Issue 83 March 2020 generators are required to supply the energy during the dark doldrums when green energy is not available. According to Hans-Werner Sinn, professor of economic research at the University of Munich, the Austrian thinktank Joanneum Research has published a large scale study has found that a mid sized electric car (in Germany – less in France) must drive 219,000 miles before it out performs a similar diesel car in CO2 emissions. Batteries will not last that long, nor will the electric car. Very large amounts fossil fuels are used to manufacture the lithium batteries in China. A report from Reuters, published a year or so ago, concluded that by 2040 (the original timetable) that the UK will have to generate some 50 Terrawatts of additional power in order the charge the 20 million electric cars. To bring this into prospective the average power station produces say 10GW (Gigawatts) of power and so 50 Terrawatts is the equivalent of 5,000 power stations, or 16million wind turbines. Solar farms produce a 500 KW/acre so you can work out that is over 1,000 million acres! Fantasy, it will never happen. Our government is closing coal fired power stations, whereas France has nuclear power stations with little or no CO2 emissions, and so the power outages are a real possibility although the distribution network thinks that it manageable. As the ownership of electric cars increases the numbers being 'plugged in' to charge increases and so does the probability of local power outages due to the heavy load and owners will be encouraged to constrain the charging period to overnight when there is less demand. The loss of fuel tax revenue from fossil fuels will no doubt be applied to the cost of electricity used to charge the car and network loading will be managed by area power reductions.
