How does a CFL benefit the environment?
Each 13-watt CFL, over the expected 10,000 hour life of the bulbs, will save 470 kilowatt-hours (kWh) of electricity as compared to a 60-watt incandescent bulb. This translates to a reduction of over 730 pounds of carbon dioxide. It also means a reduction of 1.6 pounds of nitrogen oxides and 4.3 pounds of sulfur dioxide, and makes significant reductions in other impacts of coal-produced power such as mercury pollution and destruction of forest and stream habitats.
