Power generation from fossil fuels on Britain’s electricity grid fell to an all-time low, delivering what is described as the UK’s greenest Christmas.
Data from Drax Electric Insights shows that just before midnight on 29th December fossil fuels generated 1.7GWh of electricity – just 6% of the power on Britain’s electricity grid at the time.
That compares to an estimated 24.1GWh generated by renewable sources, including biomass, wind and hydro.
The report says that a decade ago, on the same time on 30th December 2011, fossil fuels generated 18.7GWh, totalling 58.7% of the country’s power needs.
The carbon intensity of the power system fell to just 125g/KWh during the seven days from Christmas Eve 2021 – almost 75% lower than a decade earlier, according to the authors of the study.
