Once again -- for the fifth year in a row -- the University of Pennsylvania has emerged at the top of the U.S. Environmental Protection Agency's list of green power champions at colleges and universities.
Penn beat 72 other schools across the country by purchasing more than 200 million kilowatt hours of green power -- power from renewable sources -- during the current academic year.
Penn is a big place with a lot of research and a lot of power needs, so this amount turned out to be 48 percent of the school's overall power usage.
Other schools that purchased less green power -- but that made it 100 percent of their usage - include Drexel, Carnegie Mellon, Allegheny, Oregon State, Dickinson, Catholic University, American University, Hobart and William Smith Colleges, Santa Clara University, Southwestern and more.
Pennsylvania overall is looking mighty fine. Pennsylvania has more colleges and universities participating in the challenge than any other state. OF the 73 schools, 17 are in Pennsylvania.
EPA officials said Penn's power purchase is equivalent to avoiding the greenhouse gas emissions of about 27,000 passenger vehicles each year.
"By purchasing green power from renewable sources, these 17 Pennsylvania institutions are spurring the development of the nation's green power market and reducing harmful air pollution," said EPA's mid-Atlantic Regional Administrator Shawn M. Garvin in a press release. "Their commitment to renewable energy, especially at the University of Pennsylvania, is contributing to the growth in green jobs and a green economy."
