Useful and non-useful energy transfers for coal?
Useful: Energy Light Sound Non-Useful: Electricity C02
What are non examples of solar energy?
Nuclear energy
What is the name of the non useful energy?
That would be "heat", except that sometimes heat can be quite useful.
What does NADH contain that is useful to a cell?
high-energy electrons
Will energy last forever?
Energy will, but "useful" energy will not, as the available energy gets dissipated through expanding space. This is referred to as the heat death of the universe.
List several examples of how electrical energy and light energy are useful to you?
Electrical energy and light energy are useful to me in a variety of ways from the machines used to make the food you eat to the energy used to purify the water you drink. The clothes you wear are even dyed different colors from the light energy alone.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful

Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
What we energy that is not useful?
Waste energy
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.
What examples of alternative energy?
Some examples are solar energy, wind energy, tidal energy.
Is gold useful in energy production?
Currently, gold is not useful in any form of energy production.
What W is the energy that is not useful?
Waste energy.
What w is energy that is not useful?
Waste energy.
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
