Knowledge is power, or so they say. So if you're trying to take control over your energy usage, you've gotta know just how and where you're using it.

Seeing it in straight-up dollars and cents has got to be a good way to put things in proper perspective and to get you to stop leaving the air conditioning on at 65 degrees while you're at work all day. I mean, come on.
