What is not on the title:
For an entire year, that year being 2025.
Also, yes, absolute generation from fossil fuels is declining quickly. The total generation is changing way more slowly than that share.
Part of this is about a new way to store energy. In the Netherlands, they have started storing heat energy with sand, in Germany, they are using bricks. This has some advantages. It allows the direct use of heat for industrial processes and heating industrial and commercial facilities. They can either convert energy into electricity or use the heat directly. This technology can be used with a wide variety of energy sources. This includes nuclear because it allows thermal storage of excess heat from nuclear energy. This kind of setup is supposed to be more stable for the grid and more reliable for storing energy.
I think I have read that heat is hard to convert to useful energy. Can someone confirm? But the, if that's true, why use heat as energy storage?
It's a good news and a milestone to celebrate but if we count all energy and not only electricity and not only developed world then the progress is not as fast unfortunately [1].
Not a long time ago I've seen a post arguing based on the data [1] that renewables are irrelevant and should not be taken seriously and fossils will the main source for the lifetime.

When looking at hat kind of graphs, it's good to keep in mind that burning hydrocarbons is relatively inefficient: only ~20-30% of the energy in the fuel turns into useful work, while electricity is much, much more efficient. So, we need much less of it.
Still a long ways to go regardless, but much less bleak. And also, exponentially growing deployments of wind and solar are harder to spot on this 2-year old graph which goes only up to 2024.
Imagine how much better carbon emissions would be in Germany if they hadn't dismantled nuclear!

Germany has 15.4 GW of hard coal generation, and 14.7 GW of lignite, for a total of 30.1 GW:

In 2010, before the shutdowns started, it had 21.5 GW of nuclear.
So if all the other rollouts (renewables, etc) had stayed the same, but the shutdown of nuclear and coal was swapped, Germany could have reduced its emission generation capacity by an extra 66%. (Focusing mainly on coal, since that is (AIUI) the worst of the carbon emitters.)
Thanks Greens.
(Meta: I understand some folks aren't a fan of nuclear. I disagree, but recognize people have different values and weighing of priorities. But I just find it fucking stupid that coal was left to keep running by people who claim that climate change is a priority. Certainly a discussion can be had about pros/cons of new nuclear, but why the fuck would you prioritize closing current nuclear over coal?)
Those carbon emissions are tuition. Germany is now ramping battery storage, as most of Europe is, to push out more expensive fossil gas.
Ember Energy: Batteries and demand flexibility are ready to scale across the EU - https://ember-energy.org/latest-insights/batteries-and-deman... - June 24th, 2026 ("The EU battery fleet is projected to grow fourfold, from 37 GW in 2025 to 178 GW by 2030. As this growth unfolds, batteries reduce the need for regular gas backup. By 2030, EU batteries could deliver in a single hour over 80% of the power that all EU gas power plants combined can generate in the same period, up from about 20% in 2025.")

They could have done all this without dismantling nuclear power and emitting more carbon than they otherwise would have.

i love the "but nuclear" crowd as they seem to gloss over that a nuke is a steam engine and needs water. water we don't have anymore. if you follow the news in europe you'll see every summer that country X (normally france) has to drastically reduce or switch off their nukes because no water.
I live in France, and the nuclear power is working perfectly fine. France has about half the carbon emissions of Germany per capita entirely because of German neuroses about nuclear power. While occasionally, they have to turn off one or two reactors so the fish in a given river aren't too hot, it's hardly causing rolling blackouts or energy shortages.
Renewables also occasionally don't work as well, whether during the night or when the wind isn't blowing (before you retort with oh, but what about batteries, well, those would equally apply to reactors, in which case your original point is irrelevant).
>commercial nuclear generation is incompatible with a rapidly warming planet due to cooling demands
Well it's good that Germans chose coal over nuclear!
They could've, but people and politics are hard and they didn't. It is what it is, can't change the past. We win or we learn.
You think voters had no role there? I don't see nuclear power enjoying some constitutional protection as such, so choosing against it seems ok.
"You can't change the past" really isn't fatalism

But so is German industry - every day in the news either insolvency or workforce reduction and moving production to Eastern Europe - main reason often stated "expensive Energy". I wonder what are the stats for industrial production in 2025 or total energy consumption in Germany?
You make it sound like there is a causality Herr. I would be careful. Herman GDP is declining for other reasons, not for their commitment to renwables. Also, by all measures, living in Germany is still one of the most comfortable lives you can geht in earth.
