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 is the amount of unusable energy in a system called?
The amount of unusable energy in a system is called entropy. Entropy measures the level of disorder or randomness in a system and represents the energy that cannot be converted into useful work.
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 machines that create unusable energy?
Perpetual motion machines are theoretical machines that aim to create unlimited energy without an external source but violate the laws of thermodynamics, making them impossible to create in reality. Other examples of machines that create unusable energy could include inefficient or poorly designed machines that waste energy in the form of heat, noise, or other non-usable forms.
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.
Is heat a unusable energy?
Heat energy is not necessarily unusable, but it can be challenging to harness efficiently. While some forms of energy, like heat generated by friction or waste heat, may be difficult to convert into useful work, technologies such as heat engines, thermoelectric generators, and heat pumps can help capture and utilize heat energy effectively.
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.
An airplane changes energy into different forms The total amount of energy does not?

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.

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 happens to energy that is not available to be passed from one level to another?
It becomes unusable energy, for example heat.

When energy is transformed some is usedbut most is released as unusable heat energy according to the law of what thermodynamics?
According to the Second Law of Thermodynamics, when energy is transformed, some is used to do work while the majority is released as unusable heat energy. This principle states that in any energy transformation, there is an increase in entropy, resulting in the dissipation of energy as heat.
