The quality of energy decreases when you use it due to the second law of thermodynamics. Essentially, the energy spent from various reactions is processed, which reduces the amount of work needed to extract it.

The energy pyramid shows how the amount of useful energy, food, decreases as organisms in that level use it. Even though a lot of energy may be taken in at any level, more energy in the form of food that is available to the next level, is stored on the bottom level and decreases at each level as you move to the top of the pyramid. Thus, there is much less energy to support organisms at the top, so there are fewer in most communities.
Using this equation will help you understand what is going on: E=hc/wavelength h and c are constants. As wavelength increases, energy decreases. This is why UV radiation (which has a very small wavelength) has more energy than visible radiation, and this is also why UV radiation causes damage to living things
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.

When the amount of energy that a sound carries decreases, its amplitude decreases as well. This results in the sound being quieter and potentially harder to hear.
The amount of kinetic energy increases.
As the temperature of a gas decreases, the average kinetic energy of the gas particles also decreases. This is because temperature is a measure of the average kinetic energy of the particles in a substance.
The energy of the photons decreases as the wavelength increases
the amount of energy decreases the further up the food chain you go
Total energy is always conserved. However, it is possible to convert one type of energy to another. With some limitations, you can usually convert many types of energy to many other types. Whenever this happens, the amount of one type of energy decreases, while the amount of another energy increases. For example: if an object falls down, its potential energy decreases; its kinetic energy increases. Once it crashes to the floor, its kinetic energy is converted into heat - in other words, kinetic energy decreases, while heat energy increases.
The energy efficiency of the light bulb is 30%. It is calculated by dividing the useable energy output by the energy input, and multiplying by 100 to get the percentage. In this case, 30 units of useable energy divided by 100 units of energy input equals 0.3, or 30%, efficiency.

The idea is that when you convert energy from one form to another (for example, from form "A" to form "B"), the amount of energy of form "A" decreases; the amount of energy of form "B" increases; but the total of both doesn't change.
It decreases. This is because the same amount of energy is distributed over a larger area (wavelength increases, so fringe spacing also increases). Energy per unit area decreases and this is why intensity decreases.
