Top Green Power Purchasers in USA

The U.S. Environmental Protection Agency lists the top 25 largest purchasers of green power -- from solar, wind, geothermal, low-impact hydropower, biomass and biogas generation -- among EPA Green Power Partners. Combined, these purchases amount to 6.2 billion kilowatt-hours (kWh) annually, which is more than 60 percent of the green power commitments made by all EPA Green Power Partners.
