56 percent of the average U.S. home’s energy use. During winter, turning the thermostat down 10 to 15 degrees for eight hours a day can save 5 to 15 percent in annual heating costs. In the summer, do the opposite and turn the temperature up 10 to 15 degrees.
Lighting Try to complete tasks that require plenty of light during the day, when the sun is shining and the light is free. Otherwise, install efficient fixtures;, like compact fluorescent lights.
Water heating Some manufacturer’s set water heater thermostats to 140 degrees, but most homes can get by with the heater set at 120 degrees. Each 10-degree reduction in water temperature saves 3 to 5 percent on energy costs.
