the sun maintain its energy output by nucler fusion
pie
Input energy = output energy + losses
Output force
Watts is energy output. Watts is joules per second. Joules is energy.
The Efficiency of a system is the ratio (Input Energy / Output Energy). The fraction is usually expressed as a percentage.
The energy input is always greater than energy output.

Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
Output force
Watts is energy output. Watts is joules per second. Joules is energy.
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
First of all its clean energy. I mean at the end of the energy production there is no harmfull output. Second one is we have huge source at the air why not we benefit from it.
Efficiency = ( useful energy output / total energy input ) x 100
