Energy efficiency should be integral to reducing our energy needs.

A 13-watt compact fluorescent light (CFL) bulb produces the same amount of light as a 60-watt incandescent bulb and lasts 10 times as long - consuming less than 1/3 of electricity.

If every U.S. home replaces one incandescent with a CFL bulb, the energy saved can light 3 million homes and prevent release of greenhouse gases of 800,000 cars.
