EPA Publishes List of Top 20 Campus Purchasers of 'Green Power'

Four universities in Pennsylvania are among the 10 postsecondary institutions in the United States that bought the most "green power," according to a list published by the U.S. Environmental Protection Agency. The University of Pennsylvania topped the list, purchasing about 200 million kilowatt hours -- nearly half of its total electricity -- in the form of solar and wind power. Penn's Philadelphia neighbor, Drexel University, appears fifth on the list, Carnegie Mellon University in Pittsburgh is listed third, and Pennsylvania State University is sixth.
