The CFL was invented in 1976 by Edward Hammer, an engineer with General Electric. It was created to respond to 1973 oil crisis.
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Replace it, but take the old one to the correct place for disposal
A greater percentage of light, and a smaller percentage of infrared radiation and heat.
If you're using it to generate light, 10 percent efficient. If you're using it to generate heat, 90 percent efficient.
Bob the builder!
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.

An example of an energy efficient device includes an energy efficient light bulb.
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
It is the Incandescent light bulb. Most of the energy are lost as heat

The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
The energy efficient light bulb costs several times as much as the normal (incandescent) light bulb. The exact prices may vary from region to region. In any case, the extra cost will be more than compensated by savings in electrical energy, over the lifetime of the bulb.
