• Use twisty compact fluorescent lightbulbs. They are more energy efficient and can save up to 75% of electricity and last up to 10 times longer than traditional incandescents. They are now come in a covered style that resembles a regular bulb.
  • Use a dimmer. The lower the lights, the less electricity used.
  • Install motion sensors  in stairways, halls, and garages that turn lights on when you walk in and off when otion is no longer detected.(Source:Good Housekeeping March 2008)
