Chart: Solar leads EU’s power mix for first time ever

June was a monumental month in the European Union: For the first time ever, it got more electricity from solar power than any other source.

Solar provided 22.2% of the region’s electricity, per clean-energy think tank Ember, unseating nuclear and beating out gas and coal combined. Between nuclear, wind, hydropower, and solar, nearly three-quarters of the EU’s power came from completely carbon-free sources.

It’s a striking illustration of how far solar power, and clean energy as a whole, have come in the EU.

A decade ago, solar contributed just 3.5% of the region’s power while coal supplied 24.6%. Those energy sources are now on pace to essentially trade places. Across all of last year, solar beat out coal for the first time as more and more EU member states shutter their polluting coal-fired power plants. The results speak for themselves: Power sector emissions declined by 41% between 2015 and the end of last year.

Europe has been in hyperdrive with clean energy since Russia invaded Ukraine in 2022, destabilizing the region’s main supply of affordable natural gas and sending gas prices soaring. Since then, for reasons of energy security as much as climate consciousness, the EU has made a concerted effort to ditch fossil fuels even faster and rely more on carbon-free energy sources that can be controlled locally.

That push has helped drive fossil-fueled generation to record lows on the region’s power grid. June was coal-fired power’s worst month ever in the EU, accounting for just 6.1% of electricity, largely thanks to Germany and Poland, the bloc’s two biggest coal consumers, burning comparatively small amounts of the fossil fuel. Meanwhile, solar smashed records in at least 13 of the EU’s 27 member states last month.

The milestone comes as the U.S. under the Trump administration moves backward on clean energy. Earlier this month, President Donald Trump signed into law the One Big, Beautiful Bill Act, which will rapidly phase out subsidies for solar and wind energy. Last week, his Energy Department released a controversial report that experts say will likely be used to justify extending the life of aging, uneconomical coal-fired power plants.

While the Trump administration seeks to tether the U.S. to fossil fuels, Europe and much of the world continue accelerating toward cleaner options.
