I'm surprised at how trendy this is becoming, but certainly pleased.

Aspen, Colorado [RenewableEnergyAccess.com] -- Aspen Skiing Company (ASC), operator of four ski mountains and two hotels in Colorado, has made a landmark purchase of renewable energy certificates from wind farms to offset 100 percent of its electricity use. The purchase is the largest in the history of the U.S. ski industry, according to the company.

With the purchase, ASC joins other leading businesses like Whole Foods, Fedex Kinkos, Starbucks, Nike and Patagonia in purchasing large amounts of renewable energy. The 21,000-megawatt hours (MWh) purchase keeps 20,000 tons of carbon dioxide, the primary greenhouse gas that contributes to global warming, out of the atmosphere each year. Most of these businesses are members of the U.S. Environmental Protection Agency's (EPA's) Green Power Partnership, a voluntary program seeking to increase the use of green power among leading U.S. organizations.

A significant number of businesses are now buying renewable energy certificates to offset their electricity use and to demonstrate their commitment to supporting clean energy; companies like Johnson & Johnson, Herman Miller and Staples.
