End-Use Consumption of Electricity 2001

You can implement an austerity and awareness program for your household. Turn off lights, replace them with fluorescent or LED forms, and add timers where appropriate. Examine your fridge and decide what to do with it as regards replacement, cleaning, added insulation on the top and sides, etc.
A/C is a huge issue. People are using it like never before, and they are relying on it when older methods should have been used ... methods like an attic fan, strategic placement of trees, awnings and shades, etc.
The water heater is another issue. It can be given added insulation, and so can the pipes. It should be turned down. A more comprehensive change can be made by replacing such a large heater with a smaller one, supplemented by spot (electric) water heaters for sinks.
The larger problem is that our lifestyles are designed to waste energy, so everything that a person does at home tends to be wasteful, everything he buys is wasteful, etc. Dare to break out of that trap.
