because partly will be emissed to the environment, which cant be reused. For more information refer to sustainability studies, which are looking, among other things, how heat directed to the environment can be minimised
energy is released in exothermic reactions and energy is absorbed in endothermic reactions if that helps any.
This is related to the Second Law of Thermodynamics.
That would be the second law of thermodynamics.
Because the second law of thermodynamics states that any use of energy always results in a decrease in the amount of "useful" energy.
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
Since energy can't be created nor destroyed (First Law of Thermodynamics), a loss or waste of energy really means that useful energy is converted into unusable energy (Second Law of Thermodynamics).
The total energy of course won't change - you won't "gain" or "lose" energy (First Law of Thermodynamics). However, note that you are basically converting useful energy into unusable energy (Second Law of Thermodynamics).

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.

You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.

The way that the question is worded it is impossible to be sure exactly what you are looking for, but as a reasonable guess, you are looking for what happens to energy that is not producing useful work. The second law of thermodynamics generally tells us that we can never get 100% efficiency, i.e. we can never convert all the energy we are using into useful work. Some of the energy will just go into increasing the entropy of the universe.
The useful energy will be gone eventually, one way or another. As a result of the Second Law of Thermodynamics, it is unavoidable that we will eventually run out of useful energy.
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
The 2nd law of thermodynamics can yield predictions on the maximum efficiency of a process that seeks to extract useful energy. An example would be the Carnot cycle which gives the maximum percent of energy that can be harvested and turned into useful work as heat moves from a heat source to a heat sink.
No, it won't increase nor decrease. Energy can't be created or destroyed (First Law of Thermodynamics). On the other hand, the amount of USEFUL energy will usually decrease in energy transformations (Second Law of Thermodynamics).
Yes,burning fuel is a useful chemical reaction as energy is released and can be converted into different forms to do useful work
