I know this sounds incredibly easy and almost silly, but turning off the lights when you are not using them, as well as putting your computers, TV's, etc. on a power strip and turning them off nightly.
I have a home that I'm trying to sell which is currently empty. Turns out that one light left on used 4 kw of electricity per day, which translated into approximately $10 for one week. (The light was inadvertently left on.) Quite shocking to think that one light could use so much electricity.
Also, computers, TV's, DVD players, and other electronics that are plugged in 24/7 are considered "energy vampires". They use energy even when we are not using them.
