Lower the temperature setting on your water heater. In an average home, it should be set to 120 degrees.
Set thermostats between 65 and 70 degrees during the winter, and at 58 degrees when away from home more than a few hours.
Install a programmable thermostat. These electronic thermostats can automatically lower the temperature while you’re at work and at night when you’re sleeping.
Run washing machines and dryers with a full load.
Open draperies and blinds on sunny winter days to let the sun’s warmth in. Close them at night to help retain the heat.
Use kitchen and bath ventilating fans sparingly in cold weather. These fans can remove all the warm air in your house in an hour.
