Western Washington University has been ranked 18th on the U.S. Environmental Protection Agency’s list of the nation’s top 20 green energy purchasers in higher education.

The university uses 40 million kilowatt-hours of green energy annually from wind power sources. That amount accounts for all of WWU’s energy consumption, according to the EPA.

After a 2010 student-body initiative, WWU became the first university in the nation to implement a student fee for the purchase of green energy. The fee also funds student renewable energy projects such as: a 5 kW solar array, high-efficiency hand dryers, LED conversion for parking lot lights, water bottle refilling stations and hand-towel composting.

WWU was the only college or university in Washington state on the EPA’s list.
