|  | | Compact Fluorescent (CFL) Light Bulbs |  | Compact Fluorescent (CFL) Light Bulbs are four times more efficient and last up to 10 times longer than incandescents. Although initially more expensive, you save money in the long run because CFLs use 1/3 the electricity and last up to 10 times as long as incandescents. Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb. If everyone in the U.S. used energy-efficient lighting, we could retire 90 average size power plants.
