A power plant will emit 10mg of mercury to make the electricity to an incandescent bulb whenever compared with only some.4mg of mercury to managed a CFL for that same a chance. The net benefit of utilizing the more energy efficient lamp is positive, and this is very true if the mercury your market fluorescent lamp is driven out of the waste stream when the lamp increased.
