Renewable energy generated 52.1% of the UK’s electricity in 2025, exceeding half of total generation for the second consecutive year, according to government statistics.
The Department for Energy Security and Net Zero said renewables produced a record 153 TWh of electricity in 2025, up from 144.5 TWh in 2024, with the increase driven by additional wind and solar capacity, higher-than-average wind speeds, and record levels of sunshine.
Statistics show that offshore wind generated a record 17.7% of the UK’s power during the year, while wind overall remained the largest source of renewable generation, producing 29.5% of electricity supply.
RenewableUK chief executive Tara Singh said, “It’s great to see that renewables have generated over half the UK’s electricity for the second year running, outperforming fossil fuels significantly and proving once more that clean power is right at the heart of our modern energy system, consistently providing most of the electricity we need to keep British homes and businesses up and running.
“We can build on today’s milestone by attracting record levels of investment in new wind and solar projects in this year’s clean energy auction, which opened this month.”
