Corey yes thats a great tip. We are in the middle of switching all our bulbs right now. I can't believe how much better they are than regular old bulbs.
Some other ideas are replacing old appliances...obviously this is more costly but you will save HUGE with newer models. We are trying to get a new fridge right now since ours is eons old! lol.
We also have eliminated a few lights in our house. Once they are gone for a couple weeks, you no longer miss them.
