Lighting and Mercury
California's lighting produces significant sources of mercury emissions and some lighting even contains mercury. The state's coal-fired energy providers are responsible for more than 1,600 lbs of mercury emissions annually.
Mercury pollution Mercury levels vary significantly by lamp manufacturer, and range from a low of 2.2 mgs to as much as 15 mgs in 12 foot tubes. But the amount in CFLs is gradually decreasing as manufacturers work on lowering levels of mercury in their products. Also, using CFLs instead of incandescents actually reduces the amount of mercury as we will not need to mine coal for electricity. Because incandescents use much more electricity, using CFLs actually reduces mercury pollution because they use less electricity.
