Every time you change a light bulb, replace it with a compact fluorescent
Compact Fluorescents
These light bulbs, which use about 75 percent less energy than incandescent bulbs, have been around since the early 1980s. But in the past few years they've gotten better, smaller -- and cheaper. How cheap? Try five bucks, with a five-year guarantee. The reason, says Wilson, is simple: competition. "When California had its power crisis there was a huge upsurge in compact fluorescent, and Chinese companies began making them inexpensively. Now they're being made by dozens of companies, plus some utilities offer rebates." Today's compact fluorescents have electronic ballasts that switch on quickly and don't buzz. And the colors are much warmer than the ghostly white models of the past. (Wilson recommends compacts with a color temperature of 3,000 degrees Kelvin.) Visit
