Take Charge Tip of the Month: Switch to compact fluorescent bulbs

August 10, 2009

Compared to incandescent bulbs, compact fluorescent light bulbs (CFLs) emit the same amount of light, last eight to 10 years longer and consume 75 percent less electricity. Today's modern CFLs don't have the flicker and humming of the first generation of curled bulbs, so you get the same light for less electricity. According to the Environmental Protection Agency's Energy Star Program, the most savings will result from using CFLs where they will be on for longer periods of time — at least 15 minutes per usage. So use at a desk is better than in a closet.
