Home Depot - Eco Options Home Page
Home Depot has set up a section called Eco Options on their website for Earth Day 2007. (Note that it uses Flash extensively.) Sub-sections include Sustainable Forestry, Energy Efficiency, and Water Conservation. Several of the pages have calculators to help quantify the benefits of eco-friendliness, which are often more tangible (and financial) than people may think. Give it a look-see.
