Question

Question 1 If the energy returned from a resource is 20 MW and the energy invested for the same is 5 MW, the EROI of the process will be O 100 5 4 O 0.25

Answer 1

4

Step-by-step explanation:

The formula for calculation of EROI is :

`EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}`

Thus,

Energy returned = 20 MW

Energy invested = 5 MW

So,

`EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}=\frac {20\ MW}{5\ MW}=4`

The EROI of the process will be 4.
