Keep cool and save energy!

Easy Ways to Conserve

  • Close draperies or shades during the day to block the sun especially on windows that face south or west. Open them in the evening to let cool air in.
  • Keep cool air in by installing insulation and weather-stripping.
  • Turn off lights when not in use. Switch incandescent bulbs to cooler compact fluorescent ones.
  • Cook on the grill to keep cooking heat outside. When using the stove, vent cooking heat outside with a range hood.
  • Turn the air conditioner thermostat up to at least 80° or higher or use a programmable thermostat. Close doors to unused rooms. Turn air conditioners off when no one is home.


Appliance Use

  • Use a microwave instead of an oven. Microwaves use less than half the power of a conventional oven and cook food in about one-fourth the time. Ovens also heat up the kitchen, making your cooling system and refrigerator work harder.
  • Postpone doing laundry and dishwashing until nighttime to avoid peak-electric use hours. Hang laundry outside to dry.
  • Use the air-dry feature on dishwashers.
  • Service air conditioners annually and be sure the air conditioner is the right size for the area. Change the filter regularly. Choose an air conditioner with the Energy Star label when buying a new one.
  • Use an attic fan to draw hot air out of the attic. Use a whole-house fan to draw fresh air in through windows and exhaust it out roof vents. Insulate attic doors as well as attic.

According to the US Department of Energy, a well-planned landscape may reduce an unshaded home's summer air-conditioning costs by 15%-50%. Download the Landscaping for Energy Efficiency Tip Sheet. Landscaping for Energy Efficiency Tip Sheet pdf format of    landscapeee.pdf
