While PepsiCo bought slightly less green power, their 1.1 million megawatt-hours represents 100% of the company’s total electricity purchase for the year. Intel’s purchase amounts to 47% of their total electricity purchases.
Overall, U.S. businesses purchased record amounts of green power in 2008, with large commercial purchases driving the growth, according to the Center for Resource Solutions. Other top purchasers include Dell, Whole Foods, Johnson & Johnson, and Cisco.
While purchasing clean electricity is still voluntary in the U.S., green power sales increased by over half in 2007 from the previous year, the Department of Energy’s National Renewable Energy Laboratory (NREL) reported in the latest edition of Green Power Marketing in the United States, a Status Report (pdf).
