Renewable Energy Percentage Calculator

Calculate what share of total energy use comes from renewable sources.

About Renewable Energy Percentage Calculator

The renewable share is the share of total energy consumed that renewable energy generated or purchased represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

Formula

Renewable Energy Percentage

Renewable Share = Renewable energy generated or purchased ÷ Total energy consumed × 100

Renewable energy generated or purchased
The subset being measured
Total energy consumed
The full population it is drawn from

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Renewable Energy Percentage calculated?

Renewable Share = Renewable energy generated or purchased ÷ Total energy consumed × 100 The renewable share is the share of total energy consumed that renewable energy generated or purchased represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small.

Why does Renewable Energy Percentage matter?

Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

What values do I need to enter?

This calculator takes 2 inputs: Renewable energy generated or purchased, Total energy consumed. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
