Get paid for using less energy

EarthAid.net is a Washington-based start-up that keeps track of how much electricity, water and natural gas you use. It works sort of like Quicken for your finances--you plug in your online utility account information and EarthAid pulls in updates from the utility companies. The free site then shows you what you're using and when. If you reduce your energy use, you get points that you can redeem for rewards and discounts from local businesses.

This is an interesting way for utilities to promote energy efficiency. It adds another incentive to get people to use less energy.
