Free "going green" Download

Came across this site via a link in my morning mail, and found some ideas I hadn't known about.

The site is all about "going green"... and the free download gives the return on investment of a long list of changes we can make in our homes to reduce our energy usage. The exciting part is that they give the "Return on investment." How much we'll save per year if we make the change, contrasted to the initial investment.

Hope you find it helpful!
