WASHINGTON — The U.S. Environmental Protection Agency (EPA) has released its annual list of United States metropolitan areas with the most Energy Star certified buildings for 2011. The list of 25 cities is headed by Los Angeles, Washington, D.C., Atlanta, Chicago, San Francisco, New York, Houston, Dallas, Riverside, Calif., and Boston. By the end of 2011, said EPA, the nearly 16,500 Energy Star certified buildings across America have helped save nearly $2.3 billion in annual utility bills.

“More and more organizations are discovering the value of Energy Star as they work to cut costs and reduce their energy use,” said EPA Administrator Lisa P. Jackson.
