Department of Energy - Change a Light, Change the World
The U.S. Department of Energy has launched it's "2007 Change a Light, Change the World campaign" wherein it encourages "... every American to change at least one light at home to an ENERGY STAR® Compact Fluorescent Light bulb (CFL). These bulbs are estimated to use 75 percent less energy than standard bulbs and last up to ten times longer, resulting in fewer greenhouse gas emissions and substantial energy savings. This national call to action encourages all Americans to help change the world, one light — one energy-saving step — at a time."
You can make a difference ... one bulb at a time!
