But they were cancelled for similar reasons based on fears fueled by Russian propaganda.

So the Fukushima disaster and US polluted ground water are Russian propaganda for you?

The Fukushima where there has been one death attributed to radiation exposure (lung cancer that happened years later)? And 20,000 people died as a result of the earthquake and tsunami?

I have always wondered about the origins of the anti nuclear opinion of Germans. It has Cold War origins to be sure, but what kind? I suspect American intelligence has been supporting the anti nuclear movement for some time, for non-proliferation reasons - and not just in Germany. I certainly would be, if I ran the State Department.

The Soviets are a more likely culprit, as then just like now most of their revenues came from oil and gas exports. They secretly supported the Rote Armee Fraktion (Baader-Meinhof) terrorists via the Stasi, so funding the Greens to stymie intermediate range ballistic missile deployments in Germany, with securing hydrocarbon sales as a cherry on top, would not at all be out of character.

Back when I was in high school in France in the 1980s (before Chernobyl), I was already very aware of global warming and deeply resentful of the various Green parties sabotaging the one solution we had at the time.

I'm still very pro-nuclear, including Thorium and fast-neutron breeder reactors (but not small modular reactors, that are a boondoggle outside nuclear submarines), but I recognize solar or renewables combined with grid scale storage are more economical.

Once I had a discussion with a German that is a strong supporter of the green party and his argument against nuclear power was the nuclear waste and no proper was of disposing it and also building new nuclear power plants are expensive and take a long time. Then I did a deep research and created a PDF and pointed out that there has been many advances of re-using spent-nuclear fuel and minimize the environmental impac…

The "nuclear waste" argument is so weird to me. We take radioactive rocks from the ground. Make them less radioactive. Put them back in the ground. There is no output that wasn't dug up out of the ground originally. It would have been polluting the original location already.

Isn't solar the fastest energy source to spin up? Just take them out of the crate, put them on racks, tie them to the grid.

Not to sound like an ass but that's your typical HNer hot take on a topic they don't know anything about (which is 99% of topics outside of tech). I know that I don't know jack shit about the topic, but I can already tell you that if you do what you describe you'll quickly learn about why grids have frequencies, what generate these frequencies, and what happens when they drift.

Yeah that's what an inverter does, the "tie them to the grid" part. Every solar system has them, and they can islanding or not.

I guess it is, but solar can only be part of the answer: You need a solid plan (and all the infrastructure that implementing this plan involves) for when the sun does not shine, because in the more northern parts of Europe especially, energy consumption is highest during seasons in which sunlight is (relatively) scarce. Also, "the grid" cannot absorb any amount of solar energy - so if you choose to address (at least…

Iron air batteries.

Gas/Hydrogen are Germany's answer to you last point. You can store energy created by renewables this way easily and use it when needed. Right now we can't produce enough hydrogen though, so gas can be used in the meantime, but in the future the entire infrastructure, such as power plants, pipelines or port terminals can be switched to hydrogen: https://www.bundesnetzagentur.de/EN/Areas/Energy/HydrogenCor... You could…

Hydrogen is a bad idea because it is dangerous (highly explosive) and also leaky, due to the size of the atom

To transport hydrogen, you need complex infrastructure (real cold trunk or whatever) and you still leak, so the overall efficiency is bad

It's a matter of concentration

If nuclear would be cheap in the western world I'd be all for it but we just can't do large projects in our ccurrent system. Solar + wind + battery is much less of an headache.

Help from an industrial country would be required

Sad to read that Germany, that was once an industrial power, is now an empty shell :(

>Russia openly declares willingness to destroy europe There is not a scintilla of evidence for this. They're trying to keep the same violent and aggressive American dominated military alliance that is currently and actively trying to destroy Iran far away from their most vulnerable border. They also tried to pursue the diplomatic route multiple times before invading and after invading and were always rebuffed.

They started the largest war in Europe since 1945 and I fervently hope that Putin will pay for that in a way similar to Hitler. That entire war is a massive, futile attempt to revive their glorious imperial days by annexing lands that they consider their alienated property. Fuck them and their bombs and their disgusting oscillations between paranoia and megalomania. Contemporary Russia has fewer people than Pakistan…

What largest war in Europe since 1945 ?

Ha, you speak about the war between Russia and the US and friends

You are correct. Perhaps deal with all these people in the same way ? It starts with Biden and ends with countless others, all of which are equally guilty, all of which are fuelling a war needlessly.
