Very, very, lean.

But at least it’s clean. Whatever that should mean.

Clean energy sources generated the smallest amount of Germany’s electricity in over a decade so far in 2025, dealing a blow to the energy transition momentum of Europe’s largest economy.

Electricity generation from clean power sources totalled just under 80 terawatt hours (TWh) during the first four months of the year, according to data from energy think tank Ember.

That clean energy volume is down 16% from the same months in 2024 and is the lowest for that period since at least 2015.
