Green Power Champion Three-peat



For the third year the U.S. Environmental Protection Agency named Colby its Green Power Challenge conference champion in NESCAC. Colby makes 10 percent of its electricity through cogeneration and buys only green power—electricity from 100-percent renewable sources.

Colby’s move to 100-percent renewable electricity sources, in 2003, helped establish a market for green power in Maine and led to national recognition for green power use. Purchased electricity has come from hydro, wind, and biomass. The on-campus cogeneration turbine uses steam-plant exhaust, and the College buys Green-E certified renewable energy credits for specific projects. Taking those credits into account, the EPA reports that 103 percent of Colby’s electricity is green power.

In the EPA’s Green Power Challenge, Colby had the highest percentage among participating colleges and universities nationwide in the first two years and the second-highest percentage in 2009-10.
