Following in the footsteps of College of the Atlantic, Bates College announced recently it will purchase all of its electricity from renewable energy sources in Maine, specifically biomass generating plants and small hydroelectric producers, according to Renewable Energy Access. An Augusta-based nonprofit purchasing consortium, according to the article, pooled the college's resources with hospitals, other nonprofit organizations and local governments to leverage a good price. The shift to greener power will reduce the college's greenhouse gas emissions almost to their 1990 levels.
