If you replace all the incandescent light bulbs in your home with Compact Fluorescent bulbs there will be a nice reduction in your energy bill. The CLF bulbs give the same light but uses 2/3 less energy. They last up to ten times longer than ordinary light bulbs plus eliminate 70% of the heat. It is said, if everyone replaced an ordinary light bulb with a CLF bulb there would be enough energy to light more than 2,500,000 home for one year and eliminate greenhouse gases equivalent to the emissions of nearly 800,000 cars.
