Low-carbon sources of energy provided 42.9% of the UK’s electricity generation during 2015, according to figures from the UK Government’s Department of Energy & Climate Change (DECC).

The total rose from 35.6% in 2014 thanks to increased generation from nuclear power stations and from renewable energy sources, such as hydro, solar and wind.

Gas accounted for 31.3% of the electricity supplied in 2015, up from 30.9% in 2014.

Coal’s share of power generation dropped to 25.9% from 33.6% following a rise in the carbon floor price and the conversion of a third unit at Drax power station to burn biomass.

Nuclear output increases

Nuclear output rose to 23% from 20.5% after plants that had been offline towards the end of 2014 were brought back into service.

Gas extraction from the UK continental shelf rose thanks to the Breagh and Jasmine fields coming online and less maintenance work.

But the UK still imported more gas than it extracted.
