Harvard University Purchases Renewable Energy from Maine Wind Farm Harvard University reached an agreement with First Wind to purchase half of the power and associated renewable energy certificates (RECs) generated by the Stetson Wind II project near Danforth, Maine. The project will use 17 General Electric, 1.5 MW turbines. Harvard's purchase will equate to approximately 24 million kilowatt-hours per year, which represents more than 10 percent of the electricity used by Harvard's Cambridge and Allston campuses. According to the U.S. Environmental Protection Agency (EPA), the purchase makes Harvard the largest purchaser of wind power by a university or college in New England.
