Replace Incandescent Light Bulbs and Save!

Compact fluorescent light bulbs can replace the incandescent light bulbs in most light fixtures in your home, and they are now widely available. Compact fluorescent lights use one-fourth the amount of electricity that incandescent lamps use, and they last seven times longer. Because compact fluorescents use less electricity, they reduce carbon emissions, which is good for the environment!
