What is the environmental impact of CFL bulbs?
Using compact fluorescent lighting instead of regular incandescent lights has a positive environmental impact. Because CFLs are more efficient than regular bulbs, they reduce the amount of fossil fuels burned at power plants that generate electricity. By doing this, they prevent the emission of air pollutants such as mercury, sulfur dioxide (which can cause acid rain), nitrogen oxides, and carbon dioxide (which contributes to global warming).
