Earth Aid let you track your energy and water usage

Earth Aid tracks your utility usage and provides a quick comparison to previous months/years, lets you see how your friends/family are doing, and offers tangible local rewards for cutting your electrical, gas, and water use. Sign up for the Fan Earth Aid group to see how your electric/gas/water use compares to others in the area.

The green on the graph below is my electrical use for all of 2009, the blue is July and August 2010.
