How do you calculate energy efficiency?

  • Efficiency is essentially a measurement of the amount of labor or energy that may be saved throughout a process. In other words, it's similar to comparing the energy intake and output in any particular system.
  • For instance, we see that many processes result in the loss of effort or energy like vibration or waste heat.
  • The energy efficiency is calculated by dividing the energy output by the energy input, then expressing the result in percentage form. In a similar vein, a perfect process is said to have a 100% efficiency.
  • By dividing the energy input and output by 100%, we can determine anything's efficiency. This equation is typically used to represent energy that takes the form of heat or power.

Given details :

Qinn - 12,000 j

Qout - 9000 j

By applying formula

η = W/Qinn

= (Qinn-Qut)/Qinn

= = (12000-9000)/12000

= 1/4 = 25%
