The UK's use of gas and coal for electricity generation declined significantly last year, reaching its lowest level since 1957.
Gas power plants produced 31% of the country's electricity, while coal power contributed to just 1%, according to an industry journal called Carbon Brief that was cited by the Guardian.
This reduction in fossil fuel usage was influenced by increased renewable energy generation and higher electricity imports from France and Norway, the research revealed.
Renewables, including wind, solar, hydro, and biomass, surpassed fossil fuels for the third time this decade, providing 42% of the UK's electricity. Nuclear power, contributing 13%, also played a role in this shift towards low-carbon electricity, which comprised 55% of the UK's electricity mix.
The decline in fossil fuel electricity, which was two-thirds lower in 2023 compared with 2008, is part of a broader trend of increasing renewable energy sources and energy efficiency improvements in homes and appliances.
The UK's electricity demand is expected to double by 2050 as the country aims for net-zero emissions, with significant developments in offshore wind farms and other renewable projects underway.
