When I move the last things out of this house, I'm also taking out the light bulbs. When I moved in, there were none in here and since then I've put in all compact fluorescent bulbs to save electricity. They aren't cheap, I can tell you, but they paid for themselves the first month after I put them in.
My electric bill dropped by a good 30% just using these bulbs. I had no idea just how much power regular incandescent bulbs could pull, and I am consistent in turning lights off in rooms that aren't in use.
