Last month, coal power made its lowest contribution to the UK’s electricity grid in 135 years.
That’s according to new data from Aurora Research, which suggests the carbon-intensive fuel contributed only 2% to the total energy mix during July.
Meanwhile, gas-fired power made up 40% of Britain’s energy, with nuclear power accounting for 32% and renewables making up around 18%.
During the same period last year, coal made up 4% of all generation and in July 2015, its share was as high as 22%.
The analysts suggest its current steep decline could continue by falling further still in August.
Across the whole of 2016 the energy source made up an average 9% of electricity generation, down heavily from an average of 23% across 2015.
Richard Howard, Aurora Energy’s Head of Research, said: “The decline in coal in recent years is partly as a result of higher carbon prices and partly the growth in renewables.
“In August, coal load factors have been even lower than in July and the trend is continuing.”
