heat and light (if it's an AC lamp, there is also some mechanical energy which can sometimes be heard as a hum-especially with big flourescent tubes).

Turning an electric lamp on sends electrons through a filament made of a conductor that has a slight resistance. This resistance causes the energy of the electron to be converted into heat and, once the filament has heated to incandescence, light. The light is comprised of photons emitted by atoms in the filament (mostly tungsten in traditional electric bulbs) which have adsorbed enough energy to cause the outer electron shell of the atom to expand, then rebound to their original orbital diameter. On the return to the original orbit, the electron shell sheds energy in the form of photons, which we see as visible light, and infrared heat.

Light and heat. An incandescent bulb converts more electricity to heat than to light. A flourescent bulb is more efficient. It converts less energy to heat than an incandescent bulb does.

First, you should come to a decision what the that technique of 'clean' and 'organic' are. the most organic source of power is the solar; an huge nuclear reactor. image voltaic must be switched over to electrical energy (through image voltaic panels) with out any direct byproducts, even with the indisputable fact that the byproducts of the picture voltaic panel manufacture are as undesirable as the different production procedure. 2d organic source ought to probable be wind; back, no direct byproducts (except slightly noise and seen pollutants) even with the indisputable fact that the manufacture of the windmills is back, wasteful and pollutant generating. Geothermal is solid, yet in reality works in an fairly small portion of the international, and has an analogous intrinsic fault because the first 2. Hydro-electric powered is the former standby.....and also you should continually take the region that BEAVERS make dams, and no one ought to argue that beavers are not organic....
