Green Power

• December 2005: Bates signed a five year contract to use 100% renewable electricity (small hydro and biomass) to power its main buildings which account for 94% of the College's electrical consumption.
• 2006: Bates was inducted into the EPA'S Green Power Leadership Club for its role in using renewable power.
• Bates is currently investigating green contracts for its small houses (the remaining 6% of the College's electrical consumption).

Biodiesel

• Physical Plant uses a five percent biodiesel blend (B5) in the heating oil tanks in all wood structure houses and the Village Complex, reducing the greenhouse gases emitted from burning fossil fuels.
• During the 2007/2008 season the biodiesel blend was increased to twenty percent (B20) in the two Environmental Houses on Frye Street as a pilot for a campus wide increase.
