Enter the total energy captured (J) and the total possible energy (J) into the Calculator. The calculator will evaluate the Energy Yield. 

Energy Yield Formula

EY = EC / PE * 100


  • EY is the Energy Yield (%)
  • EC is the total energy captured (J)
  • PE is the total possible energy (J)

To calculate Energy Yield,

How to Calculate Energy Yield?

The following steps outline how to calculate the Energy Yield.

  1. First, determine the total energy captured (J). 
  2. Next, determine the total possible energy (J). 
  3. Next, gather the formula from above = EY = EC / PE * 100.
  4. Finally, calculate the Energy Yield.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total energy captured (J) = 40

total possible energy (J) = 75
