Calculate the percentage of total energy supplied by renewable sources.

How it works

Enter values that use compatible units and boundaries. The calculator validates the numerical inputs and applies Renewable energy share (%) = Renewable energy / Total energy × 100.

The formula

Renewable energy share (%) = Renewable energy / Total energy × 100

Variables: Renewable energy = Renewable energy; Total energy = Total energy.

Worked example

Example: 450 renewable-energy units from 1000 total-energy units gives a 45% share.
