More than half of the UK's electricity was generated from low-carbon sources in 2018, government statistics show.
The share of power generation from low-carbon technology including renewables and nuclear reactors rose to a record 52.6% last year, up 2.6 percentage points on 2017, the figures show.
Renewables such as on and offshore wind, solar and biomass generated a record one-third of power, up from 29.2% in 2017, the Digest of UK Energy Statistics (Dukes) reveals.
The rise in renewables is down to extra capacity such as wind farms being installed, while nuclear generation dropped to 19.5% of the mix due to outages and ongoing maintenance. Imports were up to 5.4% of total supply, up from 4.2% in 2017.
Industry body RenewableUK said the figures showed wind provided a record 17.1% of the UK's electricity in 2018.
