ratio of energy output to energy input.
Energy efficiency is typically determined by the ratio of useful energy output to total energy input in a system. It can be quantified by calculating the efficiency percentage, which is the amount of useful energy produced divided by the total energy input multiplied by 100. The higher the percentage, the more energy efficient a system is.
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
The ratio of useful energy output to total energy input is known as the energy efficiency. It is calculated by dividing the useful energy output by the total energy input and multiplying by 100 to express it as a percentage. A higher energy efficiency percentage indicates a more effective use of energy resources.

The ratio of brake power output to power input
The efficiency of a machine is the ratio of its useful energy output to the total energy input. A higher efficiency value indicates that the machine is converting more of the input energy into useful work output. Efficient machines help minimize energy wastage and improve performance.

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.
When calculating efficiency, work input is compared to the work output. Efficiency is the ratio of the work output to the work input, expressed as a percentage. It shows how effectively a system converts input energy into useful output energy.
The ratio of energy output to energy input is the efficiency of a system, and is typically less than 100% due to energy losses. Work input is the amount of energy needed to perform a specific task or operation, and it is dependent on the efficiency of the system.
