Introduced in the mid 1990s, CFLs (compact fluorescent lamps) are one of the easiest ways to save energy in the household. Designed to be compatible with lamps originally designed to hold standard incandescent lightbulbs, CFLs emit the same amount of visible light as incandescent bulbs, but use a fraction of the energy and have longer lifespans. Don’t let the higher price tag fool you- these bulbs will more than make up for the initial investment in energy savings. CFLs do contain mercury and require very careful disposal, especially if they break and release harmful mercury vapors into the air. See ecomii's CFL Disposal tip. In December 2007, President George W. Bush signed the Energy Independence and Security Act of 2007, which set efficiency standards for electric lights and provides for the elimination of incandescent bulbs starting in 2012.

CFLs are widely available in the same commercial outlets where incandescent bulbs can be found. Stocking up on these bulbs can save you money on your next energy bill and can also save tons of carbon dioxide from being released into the atmosphere. CFLs come in different shapes, strengths, and shades (much like incandescent bulbs) for many of your lighting needs. Try to get a EnergyStar certified bulb - you’ll have the satisfaction of knowing the bulb was approved by both the U.S. Environmental Protection Agency and the U.S. Department of Energy.
