On August 12th, Washington, D.C. Mayor Muriel Bowser announced a new power purchase agreement (PPA) for wind energy from an Iberdrola Renewables wind farm in southwestern Pennsylvania. Wind power will supply the District of Columbia’s government buildings with 35 percent of their electricity, all while saving $45 million for D.C. taxpayers over the next 20 years. This agreement is the largest purchase of wind energy by a US city to-date.
