Concern over mercury in the environment is actually another reason to choose to use compact fluorescent bulbs rather than incandescent bulbs. One of the largest sources for mercury in the environment is from trace amounts in coal that become airborne when that coal is burned for generating electricity. >From TreeHugger.com: "Ironically, compact fluorescent bulbs are responsible for less mercury contamination than the incandescent bulbs they replaced, even though incandescents don't contain any mercury. The highest source of mercury in America?s air and water results from the burning of fossil fuels, such as coal, at utilities that supply electricity. Since a compact fluorescent bulb uses 75 percent less energy than an incandescent bulb, and lasts at least six times longer, it is responsible for far less mercury pollution in the long run. A coal-burning power plant will emit four times more mercury to produce the electricity for an incandescent bulb than for a compact fluorescent." http://www.treehugger.com/files/2005/06/what_about_merc.php See also: http://www.nema.org/lamprecycle/epafactsheet-cfl.pdf http://en.wikipedia.org/wiki/Compact_fluorescent_lamp#Environmental_issues Philip Proefrock quoting "LK Dingeldein" <lkdingeldein1 [at] msn.com>: > ...
