UK Low-Carbon Renewable Power Set To Overtake Fossil Fuels For First Time

Rising renewables, low demand and cheaper power imports all helped reduce fossil fuel use in the UK power system to record lows. From a report: For the first full year wind, solar, and hydropower will generate more electricity than all fossil fuels combined. Homegrown UK renewable power will cross a significant threshold in 2024, overtaking fossil fuel generation for the first full year. Wind, solar and hydropower are set to generate a combined 37% of UK electricity in 2024 (103 TWh), compared to 35% from fossil fuels (97 TWh). Just 3 years ago, in 2021, fossil fuels generated 46% of UK electricity, while low-carbon renewables generated 27%.

Including biomass, renewables overtook fossil fuels in the UK in 2020, fell below fossil power the following year as biomass production fell, and again overtook in 2023. However, Ember's analysis raises concerns about biomass being categorised as clean power in the UK, given the significant emissions risks and lack of domestic pellet production. Bioenergy, which includes biomass and biogas power, is set to provide 14% of UK electricity in 2024.

Fossil generation in 2024 has fallen by two-thirds since 2000, with the long awaited phase-out of coal power, and gas increasingly displaced by cheaper, cleaner power sources. Coal started to decline rapidly from 2012 and since 2020, coal power has made up only 2% of generation in the UK, dropping to zero by October 2024. Gas has seen a gradual decline since 2016. Across 2024 there has been a large decrease in fossil gas power, which provided 30% of electricity in 2024 (85 TWh), down from 34% in 2023 (98 TWh).
