There are many ways to lower home energy consumption. Many are low cost and some simply take your action without spending money. Here are some helpful tips that apply to most homes:
1. Adjust your thermostat to 78°F in the summer and 68°F or lower in the winter. For non-water systems, re-adjust settings when away for at least 8-hours, but be aware that pipes may freeze if the temperatures near the pipes reach 32° F or below. Consider installing a programmable thermostat and save energy by adjusting your thermostat to energy-saving temperatures.
2. Make sure airflow to and from the heating and air conditioning system is unobstructed. Keep window treatments and household furnishings from blocking air vents. Seal duct leaks at seams and any holes with mastic or foil duct tape.
3. Check heating, ventilation, and air conditioning (HVAC) filters monthly and replace or clean as recommended by the manufacturer or every month. For maximum efficiency, have a professional check and service your system annually.
4. When replacing HVAC and appliances, look for the ENERGY STAR® rating and read EnergyGuide labels.
5. Vacuum refrigerator and freezer coils periodically and remove frost from freezers.
6. Turn off lights when not needed—keep light covers clean for maximum brightness.
7. Add sealants or foam gaskets behind electrical outlets and light switch plates, especially on outer walls.
8. When incandescent bulbs burn out, replace with compact fluorescent lamps/lightbulbs (CFLs)—they use less energy and last years longer. Read the label and fine print to ensure selection of the correct CFL for the light fixture and situation.
9. Warm air rises, so use ceiling fans for circulation and reverse direction seasonally. When the space is unoccupied, save energy by turning the fans off.
10. Lower your water heater thermostat to 120°F. Your household may have need for hotter temperatures for very soiled clothing, diapers, if someone is ill or if the dishwasher does not have a water temperature booster.
11. Install a water heater jacket or blanket to insulate the water heater - especially older water heaters.
12. Insulate hot water pipes to retain heat.
13. To cut water heating costs, adjust water levels to match the load size; take baths with less water or take shorter showers; install low flow shower heads, faucet aerators, and high efficiency toilets; do not leave water running while washing hands, shaving, or washing dishes; and repair water leaks. Wash laundry in cold water or warm water when possible.
14. In the winter, open south window coverings to allow the sun to heat surfaces. Close window coverings when outside temperatures are cold and when the hot summer sun is heating surfaces.
15. Limit standby power by unplugging chargers, computer equipment, power conversion packs, and electronics with LED display. Be aware that any base unit communicating with a portable unit (such as a cordless phone) is drawing power. Using a power strip will make powering down electronic equipment easier.
