If you're interested in saving the environment along with your money, there are numerous websites that can help you in your goals. Try Tech Forward if you want money back for your tech purchases. Choose your product from their list, pay the fee and they'll guarantee a buy-back price for you and they'll provide packaging and then recycle or resell it. A new magazine and website, AllGreen or www.allgreen.com contains articles on living a green life in all areas. We know that green has caught on in this country when there are reality TV shows and an entire channel devoted to the topic!
If you're interested in investing in green stocks, you could consider the New Alternatives fund or the Spectra Green fund. Both had returns of over 25% in 2007. Keep your eye on them!
