GreenTips Home (Index): Let There Be (Fluorescent) Light "A provision in the 2007 energy bill requires lightbulbs to be 30 percent more energy-efficient starting in 2012—a standard that will effectively phase out traditional incandescent bulbs. But why wait? Today’s compact fluorescent light bulbs (CFLs) already use 50 to 80 percent less energy than incandescent bulbs. If every U.S. household replaced just one incandescent bulb with a CFL, the Environmental Protection Agency estimates we would reduce global warming pollution by an amount equivalent to taking more than 800,000 cars off the road." --from Union of Concerned Scientists
