Cooling puts the greatest stress on your family's energy bill and the power grid. Maintain your air conditioning equipment with a professional "tune-up" to save you the cost and inconvenience of a breakdown during the hottest days! Clean or replace filters monthly. For central air conditioning systems, make sure the Seasonal Energy Efficiency Ratio (SEER) is 12 or higher.

"4 for the Planet." Just replace your four most used 100-watt incandescent bulbs with four comparable 23-watt compact fluorescent bulbs to save $108 over three years. If all U.S. households did the same, we'd save as much energy as is produced by 30 power plants annually.

About 15 percent of an average home energy bill goes to heating water. To save hot water, take five-minute showers instead of baths. Do only full loads when using the clothes washer or dishwasher. Use cold water for laundry and save up to $63 a year—detergents formulated for cold water get clothes just as clean.
