Fight the Light!
Don't leave lights on when no one is in the room. If you are going to be out of the room for more than five minutes, turn off the light.
If you know of a light that everyone forgets to turn off, make a sticker or a sign to hang next to the switch that says "Lights Out!" or "Don't Forget!"
Where possible, use compact fluorescent light bulbs. Those funny-looking bulbs produce the same amount of light by using 1/4 of the electricity. Plus, they last for years and years without burning out.
There's one light bulb that firefighters in Livermore, California, never turn off. It uses very little energy and has been burning for 101 years! Find out more about the Centennial Bulb,
