Our fuel mix
Each year, every UK energy company has to publish where its electricity supply comes from. While the industry average for renewable energy is around 40%, Ecotricity supplies 100% green electricity to its customers.
The chart to the right demonstrates where our electricity came from during 2025/26, with the mix including offshore wind, onshore wind, solar and hydro.

|---|---|---|
| Coal | 0% | 4.7% |
| Natural Gas | 0% | 31.4% |
| Nuclear | 0% | 13.7% |
| Renewables | 100% | 48% |
| Other | 0% | 2.2% |
| Total | 100% | 100% |
| Environmental Impact | Electricity Supplied by Ecotricity Ltd. | UK Average |
|---|---|---|
| CO2 Emissions | 0g per kWh | 147g per kWh |
| Radioactive Waste | 0g per kWh | 0.006g per kWh |
UK Fuel Mix disclosure information, published by Government Department for Energy Security and Net Zero, recognises electricity from renewable sources such as the wind and sun produce zero carbon dioxide emissions at the point of generation.
The green energy purchased by Ecotricity customers is supplied to the National Grid network. Our domestic and business customers receive electricity via the National Grid and Distribution Network and not directly from our green energy generators.
