The university is a founding EPA Green Power Partner and a recipient of a 2001 Green Power Leadership Award for making, what was at the time, the largest single retail purchase of wind energy in the nation. The university supplies 15 percent of its energy needs with a mixed portfolio of Pennsylvania wind, national wind, low-impact hydro, and landfill gas. By 2008, 20 percent of the school’s energy will come from renewable sources. Housing and dining installed 75 vendor misers on campus to reduce the power used by vending machines by 46 percent. Although the university has shown a commitment to emissions reductions through its actions, it has not signed a formal agreement.
