Mercury, lead and other heavy metals all have the potential to be hazardous wastes. Using CFLs also results in reductions of other air emissions from power plants, including carbon dioxide, a greenhouse gas. The EPA estimates that standard coal-fired power plants emit 5.5 milligrams (mg) of mercury to power an incandescent bulb over its lifetime, in comparison with 1.2 mg of mercury to power a CFL over the same period of time. Certified by the EPA's Energy Star Program, CFLs use up to 75 percent less energy than a standard incandescent bulb, can last up to 10 times longer and save $30 or more in electricity costs over the life of the bulb.
