Lighting
The wattage rating tells how much electricity a bulb uses, not how bright it is. Compact fluorescent light bulbs are a bright idea. They use less electricity and last up to 10 times longer than incandescent bulbs. Standard incandescent bulbs use only 5 to 8 percent of their energy to produce light. The rest is dissipated as heat. There are many other devices that can help save energy on lighting such as automatic timers, motion sensors and dimmers.
