Designing your own electricity system - part 6 (energy efficiency)

See http://repairyourworld.blogspot.com/2008/12/preventing-load-shedding-power-failures.html for my initial efficiency saving list.

Here are some more notes:

1) Turn off everything at the wall when the appliances are off so that nothing runs on standby.
2) Don't leave computers on when they aren't needed.
3) Try to use laptops where possible.
4) Playstations use a lot of electricity and should not be left on standby.
5) Is your house properly insulated. Are there gaps between windows and doors where hot or cold air can escape?
6) Use CFL lights instead of incandescent (normal) lights. Incandescent lights were designed 100 years ago by Edison and Tesla. CFL globes do contain mercury, but so do fluorescent globes. And the fillings in our teeth. All need to be disposed of properly.
7) If you have an airconditioner on and you need to put on a jersey, then you are wasting resources. Turn up the airconditioner. A minimum setting of 21 degrees should be cold enough.
8) If it is a very hot day, set the airconditioner temperature to less than 10 degrees below the outside temperature. You will feel the cool air and will save a lot of electricity; eg outside air temperature is 35 degrees celsius; minimum air conditioner temperature should be 25 degrees celsius. This excludes data centres and computer rooms and other rooms which need to be kept at a constant and lower temperature than this.

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...

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...

Jewish people have some secrets. Here are two of them.

One of these secrets is that we have one day off a week. Another of these secrets is that we welcome dissenting and opposite views. We  welcome Outliers. The Zohar and Talmud are full of opposing opinions and views, even opposing legal  views. I’m studying The Zohar, the Ancient Book of Kabbalah, which dissects the Tanach  and shows why things have been said the way they’ve been said and why things  happened the way they happened. There are many times when I read something, and I  don’t agree with it. I know that if I wait then at some point I will get an opposing view,  which I may or may not agree with. There are even discussions about why a word might  have an extra vav, or why a word doesn’t have a vav. Unfortunately, this internal strength in Judaism is used by our enemies to undermine us  as they will find a Jew who is against Zionism or who uses words like Occupation or  Genocide to say that this is how Jews feel generally. Yet if they...
