Many constructive steps can be taken to conserve energy atprices ranging from a few cents to a few hundred dollars: Shade windows that get the most sun to ease the burden on the airconditioner. In the winter, open the curtains of south-facingwindows to capture free solar heat. Lower the hot water heater temperature to between "low" and "medium"(120 to 140 degrees). But if you have a dishwasher it will need aheat booster to bring the dish-washing water to 140 degrees. Install low-flow shower heads to reduce the amount of water that hasto be heated for each shower. Clean the refrigerator's heat exchanger coils frequently, and leavespace behind the unit to allow air to circulate around the coils. Use small appliances for cooking when possible. Toaster ovens,crock-pots and microwaves use much less energy than an electric rangeor gas oven. Substitute compact fluorescent bulbs for incandescent ones. Theylast 10 times longer and use one-quarter as much electricity. Install a "setback" thermostat to adjust the temperature of thehouse automatically according to the hours people will be there.
