I discovered the Low Impact Living website a while back. It has an easy to use Environmental Impact Calculator that you can use to figure out how much of an impact on the world you have and how to make your household more environmentally friendly. They are now running a contest to find the household with the lowest impact. The winner receives $500 to use on low impact living stuff. They are also picking one random person who uses the calculator to win $250 of low impact stuff. Even if you don’t win, by doing some of the things they suggest for you, you can easily safe money and resources. So everyone wins!
Check it out at Low Impact Living.
