This power-outlet adapter could save you a wad of cash

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. That's the idea behind the new Belkin Conserve Insight, a $30 power-outlet adapter with a small screen that tells you just how much the item plugged into it is costing you.

The small digital display is able to tell you just how much juice is being used by any device in watts, dollars or carbon dioxide. 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.
