Home Energy Conservation

The majority of energy used in homes goes toward heating, cooling, and lighting. Use the tips below to save money on your energy bills.

Lights, Water Heaters, & Appliances

  • Turn off lights when you leave a room.
  • Switch to compact fluorescent (CFL) bulbs — or other efficient bulbs — in lighting fixtures.
  • Run dishwashers and washing machines with full loads. Use the appropriate load settings.
  • If you're buying new appliances, look for ones with the ENERGY STAR® logo.
  • Set your water heater thermostat to 120°F.
  • Clean your dryer's lint screen before running a new load.

More details on appliances are in the Energy Efficient Homes series of publications:

HVAC System

Heating, ventilation, and air conditioning (HVAC) systems can account for more than 40% of home energy use—and that means more than 40% of the energy bill.

  • Clean or change your air filters once a month.
  • Make sure your home is properly insulated and has good ventilation.
  • Make sure your furniture isn't blocking vents or air outlets.
  • Weather-strip any cracks or openings around your windows and doors.
  • Install a programmable thermostat to better regulate your home's temperature.

More details on HVACs are in the Energy Efficient Homes series of publications:


  • Set the thermostat at 78°F or higher. Wear light clothing to be more comfortable.
  • Seal gaps between window AC units and the window frame.
  • Use ceiling fans to make the room feel cooler, but turn them off when you leave the room.
  • Shade bright windows to prevent heating from sunlight.


  • Instead of turning on heat during cooler weather, put on a sweater and an extra pair of socks.
  • During the day, open your curtains to let in the sun. Close them at night to keep heat inside.
