Mercury is an element found naturally in the environment and emissions are both natural and man made. CFL light bulbs contain 4 milligrams (mg) of mercury, but by comparison, the older home-use thermometers contained 500 mg of mercury! The majority of mercury released in the U.S. actually comes from coal-fired power plants (51%).
Burning coal to provide electricity creates large mercury emissions we might overlook — but using CFL bulbs helps reduce the draw of electricity, thus creating a WIN-WIN, which we love around here.
Do you wonder about the mercury in these bulbs?
