The EPA announced, in Pollution Engineering, that it was the first federal agency to buy 100 percent of its power from renewable sources. The agency signed a contact with 3 Phases Energy Services to purchase over 100 million kilowatt hours in renewable energy certificates. The agreement extends green-power purchases to over 190 EPA facilities across the country.

This recent agreement brings the agency’s total purchases to nearly 300 million kWh per year, which is equivalent to its annual usage. This is the same as powering 27,970 average American homes each year.

“At EPA, we don’t just talk the talk, we walk the walk,” said EPA Administrator Stephen L. Johnson. “For 35 years, EPA has been greening our nation’s landscape. By committing to alternative, renewable power sources, the agency is meeting the president’s call to green our nation’s energy.”
