What is all the energy involved in the incandescent light bulbs?

Most of the energy goes into heat, but, fortunately, some it goes into light. A few bulbs may buzz and emit some energy as sound. The white light that comes out includes some infrared, which doesn't help you to see, but it does transmit heat, so you could think of that as another energy. The filament is heated by an electric current flowing through it, which encounters resistance in the filament which makes it heat the filament. It gets so hot it glows in the visible spectrum -- just as your body glows in the infrared spectrum (so infrared goggles can see you in the dark.) The tungsten atoms on the filament's surface are often boiling hot and would like to jump off and fly to the glass bulb, and some do, but many are bounced back by the small amount of gas in the bulb, which lengthens the life of the filament. These fast atoms have kinetic energy (energy of motion). When they're not flying away, they jiggle in place, which is vibrational energy, like a ball on a spring. Of course, that's how heat usually exists anywhere: as vibrations at the atomic or molecular level. The light from the hot filament inside goes in all directions, so usually there is some reflector to make it shine where you need it. That reflectance isn't perfect, so some of the light turns into heat.

DO incandescent light bulbs waste less energy than compact energy than compact fluorescent bulbs?
no
What is the difference between halogen and incandescent bulbs?
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
Give you two sources of light energy?
Two sources of light energy include the sun and incandescent light bulbs.
Are energy saving light bulbs brighter than regular light bulbs?
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
Which save more energy incandescent light bulbs or fluorescent?
Fluorescent light bulbs use less electricity for the amount of light produced.
Do incandescent light bulbs waste less energy than compact fluorescent bulbs?
Incandescente light bulbs waste quite a bit more energy than most alternatives.
What makes LED light fixtures energy efficient?
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
Which type of light bulbs use ¼ of the energy used by incandescent bulbs?
Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.
10 disadvantages of incandescent light bulbs?

What is an example of common technology that does not efficiently convert energy?
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.

Where can one purchase energy efficient incandescent light bulbs?
Energy efficient incandescent light bulbs can be purchased from most lighting stores and major supermarkets. They can also be purchased online at places like Home Depot, Amazon and Earth Easy.
