they take the waves of energy from light and run the waves though a energy transporter then therefor you have energy

Because when you rub your hands together, it causes the molecules on your hand to move in random motion, which is thermal energy.
"the energy in moving things is mechanical energy. wind, moving water, and falling rocks all have mechanical energy. when you walk, run, or ride a bicyle, you are using mechanical energy. sound is a form of mechanical energy."-Concepts and Challenges in Physical Science
Move a conductor through a changing magnetic field and run a light off the current generated.

Yes, solar light gets energy from the sun which uses less energy than artificial light. Also, solar lights don't run out of energy.
Energy is made when you are running and then you burn off the fat that you ate if you were to eat and then go for a run or light jog
There is nothing - absolutely nothing - that can never run out of energy.
what happens when a fuel is burnt?A. Gasoline (or any petroleum fuel) is mostly carbon that when burned releases energy from the form of heat energy makes the engine run and allows objects to move
Because w/o a generator, if you wanted a light on your bike you had to carry the energy with you. Either as batteries (which can run down) or as fuel for some sort of burning torch, which also can run out. With a generator OTOH you'd always have a light as long as you were able to keep moving.
A light bulb converts energy from one form to another: from electrical energy to thermal energy in the form of light and heat. Most light bulbs which have an incandescent filament convert electricity into some light energy plus a lot more heat energy, whilst the type of light bulbs which use fluorescent tubes create much less heat and thus require much less electrical energy to run. Typically, to produce the same amount of light energy, compact fluorescent light bulbs require only 20% of the electrical power drawn by incandescents.
