Repair Your World: Solving the electricity crisis at no tax cost to the treasury

My latest letter to the Cape Times editor. Melanie Gosling's articles this week and NERSA today (24th February 2010) approving 25% increases (95% over 3 years) refer. My company has a number of clients who wish to provide their own energy. We don't believe that we can rely on Eskom energy. It isn't sustainable. It isn't clean. Not only is coal polluting the air, mining it is polluting our water resources and destroying our roads. If we weren't in a recession Eskom energy wouldn't be enough for our requirements, so there is no true security of supply, especially as Eskom has not got the increase they wanted. Lastly, in the medium to long term, Eskom's energy is not affordable for our clients and there are already affordable alternatives. However, most of the clients we consult to are too small to fit into the 1 Megawatt bracket which gets the feed in tariff (REFIT). And the REFIT itself is a farce because the government has implemented a tender system w...

Preventing Load Shedding (Power Failures)

Dear all There are a few very simple ways of preventing load sheeting and potentially preventing the building of any more power stations in South Africa: 1) Switch off all appliances at the plug including computers, tv's, etc, when they are not being used. If it is inconvenient to get to the plug, use an extension cord from the wall and plug the plug in the wall into the extension cord. You can then unplug the plug at any time. 2) Don't run more than one of the following appliances at the same time: washing machine, dish washer, iron, lawnmower, kettle, microwave, kitchen mixer, oven/stove. 3) Switch off your playstation when it is not in use; same with your DSTV decoder. Both draw almost as much power when they are on standby as when they are on, so if you only watch 3 hours of TV a day, you are wasting electricity for the other 21 hours. 4) Try to use a laptop instead of a PC. Laptop's can save up to 95% of the electricity that PC's use. 5) If you use air-conditio...

Designing your own electricity system - part 7 (fridges)

Here are some specifications regarding energy saving fridges. Tafelberg sell some of the Ardo range of fridges. The Ardo rating is: 130KWH rating per year. Even if it really uses 165KWH per year, that will be amazing as an A++ energy star fridge is rated at 380KWH per year and a normal fridge much higher than that. My normal fridge (which I still need to replace) uses approximately 660 kwh per year which at 70 cents per kwh (my rate) is about R40 per month. Note that this is only based on one day's usage. After a few months, I will have a more accurate number. The Ardo fridge uses about 40Watts when it is on and is so quiet that a friend on mind has it in his passage outside two of the bedrooms. At 165kwh per year , the Ardo fridge costs R10 per month. A normal fridge is about R2000 and an Ardo fridge is about R8000. The difference is R6000, so R6000 / R30 (saving) = 200 months = 17 years. Not a very good payback period, but remember what I said in an earlier part of this blog s...
