Buy an Energy Star -certified fan. These models are more than 50% more energy efficient than conventional models. That’s money in your pocket every time you use it.
Turn it off when you leave the room. Remember how fans work? They don’t cool air, they cool people. So unless you’re in the room, you won’t get that wind chill effect and you’re wasting energy.
Make sure your install a CFL or LED lightbulb in the light fixture if your fan has one: incandescent lightbulbs add heat to a room, and CFLs and LEDs burn cooler and use about one-quarter of the energy.
