Use Energy-Efficient Appliances TO CUT pOWER COSTS Eskom’s 8% average power tariff increase for the next five years granted by the National Energy Regulator (Nersa) recently,may have detrimental effects on many businesses in the country.
on your electricity bill every month. The most efficient refrigerators are over and under fridge-freezer combinations. Manual defrost freezers are generally more efficient than automatic defrost models if they are properly maintained.

Choose appliances that run on natural gas rather than electricity.
The 8% electricity price hike which is part of Eskom’s Third Multi-Year Price Determination (MYPD3) will see the average cost of electricity being increased to 65.51 cents a kilowatt hour in 2013/2014 up to 89.13c/kWh in 2018.
Eskom’s MYPD3 covers a five-year period from 1 April 2013 to 31 March 2018 and the total revenue approved by Nersa for this period amounts to R906 553 million. As part of its MYPD3 application to Nersa, the power utility included the proposal to restructure its retail tariffs which are applicable to various customer categories in urban, rural, residential and local authorities.
The small businesses within the hospitality industry, and particularly tavern owners, could feel the pinch of the high price of electricity more than other sectors. This is mainly because of the nature of their businesses where beer and all other beverages have to be kept in the refrigerators and coolers in order to be served chilled.
Refrigerators and freezers consume about a sixth of all electricity in a typical home - using more electricity than any other single household appliance. And, if your refrigerator or washing machine is more than a decade old, you’re spending a lot more on energy than you need to.
Today’s major appliances don’t consume energy the way older models do because they must meet minimum required energy efficiency standards. These standards have been tightened over the years, so any new appliance you buy today has to use less energy than the model you’re replacing. For instance, if you buy one of today’s most energyefficient refrigerators, it will use less than half the energy of a model that’s more than 12 years older. Buying a modern or energy-efficient refrigerator could give you huge savings
Tips to Save Energy:
• The freezer should be defrosted if ice build-up is thicker than 5mm. • Vacuum the coils in the back of your refrigerator twice a year to maximize efficiency. • Make sure the fridge is not positioned next to the stove, dishwasher or exposed to direct sunlight, which will make the appliance work harder. • If your refrigerator has an energysaver (anti-sweat) switch, it should be on during the summer and off during the winter. • Make sure the seals around the doors are not cracked or torn, which will mean the cold air leaks out. • Freezers work best if they are full – if yours is on the empty side, put a building brick or two inside. These will become very cold and act like a cool box brick meaning the freezer won’t have to work as hard.
Water Usage
Geysers account for approximately 40% of the household energy bill. But if you can set the geyser temperature to 60 degrees, you will see a noticeable drop in the electricity bill, but no noticeable difference in temperature. This is how you can Save Energy through Water Usage: • If you can afford it, install a solar water heater. • Insulate both the geyser and pipes to keep the water warm – the savings in electricity make it a good investment. • Allowing hot water to pour out of taps and down the drain is wasteful. • Take a shower instead of a bath to save on hot water and use an aerated (low-flow) showerhead to control the amount of water used.
• If you have an old cistern, put a brick in it. This will mean you use less water that has gone through a very energy intensive process before it gets into the cistern.
Gas Equipment
Whenever possible choose appliances that run on natural gas rather than electricity. Look for dryers, stoves and water heaters that run on natural gas. If you have a gas furnace for home heating, change the filter monthly to save money and be sure that all cooking burners are burning with a blue, coneshaped flame. A yellow flame indicates clogged air inlets or burners that need adjustment or the valves need cleaning. Check the seal on your gas oven door. Gaps or tears in the seal will let heat escape and waste energy. Keep the hobs and the reflectors on stove tops clean and debris-free - they will reflect the heat better, and you will save energy.
Dishwashers
Modern dishwashers are almost always more energy efficient than doing the dishes by hand if they are used responsibly. • Only start the dishwasher when it is full and loaded correctly. • Scrape leftovers into the bin before loading plates. • There is no need to pre-rinse under running water – the high temperature and pressure will remove stubborn stains during the cycle. • Use the economy setting wherever possible. • Use rinse aids to ensure the dishwasher works at maximum efficiency.
Home equipment
If a device is plugged into an outlet, it is consuming energy, whether it is being used or not. Unplug DVD players and TVs at night. Or plug them all into a power strip which can be switched on and off conveniently. Sixty percent of electricity consumed by such appliances is done so while they’re idle, powering light displays or utilizing “instant on” features. Unplug ‘wall warts’ - plugs attached to a black transformer box, like cell phone chargers.
