The term "unused" is difficult to define in this contest.
- May forms of energy such as potential energy and chemical energy can be stored against use
- We do not have the technical knowledge to tap some energy
- Some energy fro large sources like the sun radiates away from us and cannot be tapped
- In industry there is some energy that is produced but wasted due to equipment inefficiency. As an example a car uses only about 30% of the energy provided.
- Some energy is of too low a value to collect and use

What machines that create unusable energy?
Is the question 'What machines create unusable energy?' All machines create unusable energy because entropy increases; 'You can't break even. '(C P Snow).
Is heat a unusable energy?
Heat, by itself, is unusable. It is the heat difference that makes it usable.
What is the difference between usable energy and total energy?
The difference is the unusable energy.
Is Energy can be change completely from one form to another?
Usually not; some energy is usually wasted. Although energy can't really be destroyed, part of the energy is converted to an unusable form.Usually not; some energy is usually wasted.

What happens to the energy not passed on to the next level?
It is lost, in the sense that it is converted into unusable 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.

Does the second Law of Thermodynamics contradict the First Law?
Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

An airplane changes energy into different forms The total amount of energy does not?
The total amount of energy doesn't change. However, some useful energy will be converted into unusable energy.The total amount of energy doesn't change.

Can energy be regenerated?
According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.

What is a quantity measuring energy unusable because of disorder?
Entropy
What does mechanical energy transform to?
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
Friction doesnt convert energy it actually destroys?
Friction converts movement into unusable energy.
