Energy Saving Lightbulbs

Compact fluorescent lightbulbs, known more affectionately as the energy-saving bulbs, have actually been available in the U.S. for a number of years, but Americans have been slow adapters. That's about to change as G.E. (who owns 60% of this market) and Wal-Mart team up to push these products on the public.

One bulb can last 6-10 years, saves you $30-35/year in energy costs and reduces carbon emissions. (Coal plants provide 50% of the country's electricity.)

While they are 6-8 times more expensive than ordinary bulbs, with Wal-Mart buying in bulk, look for those prices to fall, as competitors try to keep up with the retailing giant.
