US grocer Safeway has announced that it will purchase 100% renewable energy to power the company’s 270 fuel stations in the United States, its 15 stores in San Francisco, and the Safeway corporate campuses in Pleasanton and Walnut Creek, California.

Through a partnership with the US Environmental Protection Agency (EPA), Safeway becomes one of the largest buyers of green energy in the United States and California’s largest buyer of renewable energy. Safeway is now the only retailer to purchase enough renewable energy to power 100% of its US fuel stations.

“Protecting the environment and conserving our nation’s valuable energy resources is something that Safeway and our customers care deeply about,” said executive vice president Larree Renda. “By powering our fuel stations, stores and corporate offices with wind energy, we are taking a leadership role in using cleaner sources of electricity.”
