What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as heat
What light bulb is most energy efficient and why?

How do you know a light bulb transforms 100 percent of its electricity into light?
You don't. A light bulb transforms only a fraction of its energy into light, and most of it into heat. For an incandescent bulb about 3% is transformed into light, while for a compact fluorescent (low-energy light) about 15% is transformed into light.
Does a light bulb use more energy when in the dark?
For most light bulbs, they consume equal amounts of energy regardless of bright or dark environments. This is because a light bulb is simply lit up by a power source, and is unable to control brightness, producing the same amount of light. That is why most people say we should not waste energy by switching on a light bulb in the day.
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
What light bulb uses the most energy?
not the squiggly ones they are good for the enviornment! :-)
What is most energy given off as?
It depends what it is... if you were talking about a light bulb for instance.. more heat energy is given off than light.
What causes the bulb to light in closed circuit?
Energy flowing through the filament. In a traditional incandescent bulb most of the energy is radiated as heat which is why they are viewed as inefficient.

Why is the power of a light bulb large?
Most light bulbs waste energy as heat. Even LEDs. Large light bulbs require more power.
What can electical energy convert into?
Electric Energy can be converted into many different forms of energy. The most common type of energy electricity is converted into is light energy - as with a light bulb. Another form of energy electricity can be converted into would be kinetic (motion) energy.
Does a 60 watt light bulb evaporate water faster than the sun?
Faster than ambient left alone? If compare to open air then it is faster with extra heat source of 100 Watt. If it had twice the bulb then it is faster than 1 bulb. Light bulb is the energy source and evaporation require energy. Provide extra energy help speed up evaporation.
