Online Extra: Congress must act on energy efficiency

In this mention

Guest columnist Dr. James B. Atkins argues that energy efficiency is the quickest and least-costly path to meeting South Carolina's future electricity demand while addressing climate change. He cites studies showing energy-efficiency programs could reduce U.S. energy demand by 38-65 percent by 2030 at a cost of 3-4 cents per kilowatt-hour, compared to 7-10 cents for new generation. Atkins calls on Congress to pass meaningful energy-efficiency standards and urges South Carolina's General Assembly and Public Service Commission to require utilities to implement robust efficiency programs.
