From MSNBC.com:

"Soon after eco-conscious Western students voted to tax themselves to make their school the 22nd largest green-power purchaser in the nation, students at The Evergreen State College in Olympia took similar action. School initiatives like these are now under way across the Northwest -- a movement that has implications not only for campus politics, but also for the energy industry.

'We see a trend in university purchases across the country,' said Rob Harmon, vice president for renewable energy programs at the Seattle office of Bonneville Environmental Foundation, which markets green power to public utilities.

Beginning this academic year, all power purchased through Puget Sound Energy at Western's and Evergreen's campuses comes from renewable energy sources, which include wind, solar, landfill gases, and biomass. Hydroelectric power is renewable but is typically not classified as green because hydropower is considered more damaging to the environment.
