So far it's an industry supported initiative to help consumers migrate to the newer energy efficient bulbs and not a total ban on the old technology.
They estimated that if all inefficient traditional incandescent bulbs sold in Europe were to be replaced with more efficient bulbs — such as compact fluorescent lamps or CFLs — the continent would need 27 fewer power plants.
Most power plants are fueled by coal, which releases carbon dioxide on being burned. Those and other manmade CO2 emissions, in turn, are thought by most scientists to be warming Earth.
