In yet another step aimed at enhancing its image as an eco-friendly grocer to the world, Whole Foods is set to have its energy needs met by Colorado-based Renewable Choice Energy, a purveyor of wind-generated energy. This leap into “green” power makes Whole Foods the largest user of renewable energy in the United States, and upholds the company’s position as a leading food supplier to the environment-minded metrospiritual set.

But Whole Foods isn’t the only corporate heavyweight reliant on an earth-friendly energy source. According to the Environmental Protection Agency, the U.S. Air Force and home products giant Johnson & Johnson are also two of the country’s largest consumers of renewable energy.
