Once dismissed as buzzing tubes in offices, fluorescent lights have gone compact and upscale. Energy-saving compact fluorescents (CFs) now rival the cozy, warm light of traditional bulbs. They use a fraction of the electricity, which means lower electricity bills and millions of tons less global warming pollution. And in the summer, because they don't burn as hot as incandescent bulbs, they'll lower your cooling bills. If every household replaced just three 60-watt incandescent bulbs with CF bulbs, the pollution savings would be like taking 3.5 million cars off the road!
