The development of energy-saving lamps is the way of mankind, although it will produce a certain degree of mercury pollution, but it is much smaller than the more power consumption leads to the generation of electricity in the process of generating mercury pollution is much smaller than the short life of the lighting produced by the pollution is much smaller than the short life of the lamps, and energy-saving lamps produced by the pollution can be avoided by lowering the content of mercury in the lamps and effective recycling.
Electronic powders, argon atoms, and ultraviolet light do not cause pollution.
