New light bulb energy efficiency standards proposed by the U. S. Department of Energy (DOE) completed the gradual phase-out of inefficient everyday incandescent bulbs required under a 2007 law passed by a bipartisan Congress with industry support. And once all of America's approximately 4 billion lighting sockets contain energy-saving bulbs that meet the standards, U.S. consumers and businesses will save about $12.5 billion every year--and gain cleaner air and a healthier environment.
