There's a fun animation on Silk's web site that offers a tour through a virtual house and offers tips to improve energy efficiency. To get it to the animation, register a product UPC (they have some for you to copy and paste if you don't have one handy) then click the 'Virtual Green House' link.
Each time you visit the Silk Sweepstakes site and enter a UPC from a green-capped carton of Silk Soymilk, the company will make a donation to The Bonneville Environmental Foundation, the organization that provides Green Tags.
In addition, when you register a UPC at the site, you enter a sweepstakes to win a green home makeover, including energy-efficient appliances, Gaiam® products and Green Tags.
