Renewable Energy Percentage at 36% renewable electricity target for the period: a worked example

This worked example runs the renewable energy percentage numbers for a tougher week than the baseline: 36% renewable electricity target for the period instead of the typical 50%. Calculate renewable electricity share from renewable kWh, total electricity use, and a target percentage.

The inputs for this scenario

  • Renewable electricity supplied (contracts plus on-site generation): 920,000 kWh (held at the documented default)
  • Total site electricity consumption: 2,500,000 kWh (held at the documented default)
  • Renewable electricity target for the period: 36 % (the input this scenario stresses; the baseline uses 50)

Working through the calculation

  • The calculation starts from the formula this tool documents: Renewable energy percentage = renewable electricity supplied ÷ total electricity consumption × 100.
  • Renewable electricity share works out to 36.8 % at these inputs, and this is the headline figure for the scenario.
  • Gap to renewable electricity target works out to -0.8 points at these inputs.
  • Renewable electricity supplied works out to 920,000 kWh at these inputs.
  • Total electricity consumption works out to 2,500,000 kWh at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where renewable electricity target for the period sits at 50% and the headline result is 36.8 %, this scenario lands almost exactly on the baseline at 36.8 %.
  • Use it for quarterly or annual ESG reporting, RE100 progress tracking, or sizing the next PPA or REC purchase needed to hit a goal. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Renewable electricity share: 36.8 % (headline result)
