Turn your computer off while not in use.
Switch to Compact Fluorescent Light bulbs.

Turn the TV off if you're not really gonna watch it.
Don't leave the door open long. (I hope you weren't actually born in a barn. lol)
Don't have the refrigerator door open long. (The light actually does go off when you close it. :p )
