It depends. If you are going to leave a light on for an extended period, fluorescents are more efficient at converting electricity into light than an incandescent bulb. The circuit that ignites the plasma uses quite a bit of electricity so, if the light will be turned on and off frequently, the fluorescent may not be much more efficient. The most efficient is LED technology, light emitting diodes. LEDs generate very little heat (which is where the "wasted" energy goes.

yes they do. A 100 watt bulb can run on only 13 watts--using 400 percent less electricity that the standard bulb. And that's just for a single bulb. Imagine if you had those bulbs in every lamp in the house?!!
