Last year saw supply of both renewable energy and natural gas increase across the European Union, while coal and petroleum product supply continued to decline, according to Eurostat data.
In 2025, natural gas supply increased by 2.3% to approximately 13.1 million terajoules (TJ), marking the second consecutive year of growth following the sharp decline recorded in 2023.
Renewable energy supply also increased, rising 1.4% year-on-year to 11.5 million TJ. Elsewhere, supply of nuclear energy edged up by 0.2%, reaching 650,648 gigawatt-hours (GWh).
The data highlights the continued shift in Europe’s energy mix, with renewable energy remaining the EU’s largest source of electricity generation despite a slight fall in renewable electricity output caused by weaker hydropower production.
Coal continues to decline
As regards coal, meanwhile, last year saw a continuation of its long-term decline – brown coal supply fell by 7.7% to 184.7 million tonnes, while hard coal supply dropped by 3.2% to 107.1 million tonnes.
‘Both figures are the lowest recorded since the data series began in 1990,’ Eurostat noted.
Petroleum products also declined, with supply falling by 2.8% to 448.7 million tonnes, the data showed.
Renewable energy
Amidst the changing energy landscape, renewable energy retained its position as the EU’s leading source of electricity generation last year, accounting for 47.2% of total electricity production, Eurostat noted.
Renewables generated approximately 1.33 million GWh of electricity, although output declined marginally by 0.5% compared with 2024, primarily because of reduced hydroelectric generation.
Electricity produced from fossil fuels increased by 3.2% year-on-year to around 830,000 GWh, representing 29.6% of total EU electricity generation.
Finally, nuclear power contributed 650,648 GWh, accounting for 23.2% of electricity production, with output increasing slightly by 0.2%. Read more here.
