Solar is great but so is nuclear. They have different use cases, we need both.

Nukes are very expensive to build, but easily the cheapest energy is that you have a nuclear power plant up already and you keep it running. Germany royally fucked that one up.

Nuclear is not there when you need it. It's prohibitively expensive to build, it takes decades to finish. If we wait for nuclear power to replace coal, we'll be at 4°C.

Better stop complaining about that fantastical technology and use the tools that are there. They're quite good already, we can do it.

You’ve got some valid points in your criticism of nuclear. They are also points that could be addressed - we built lots of nuclear power plants within budget and timelines, once. Like solar, and like everything, nuclear benefits from scale.

Similarly, there are valid points of criticism that solar gushing ignores: Power is needed 24/7, solar doesn’t deliver power 24/7 and batteries (pumped hydro, chemical, heat etc) are nowhere near large enough to see the whole of society powered through the winter. If we built renewables like we built traditional power plants we would say “I’d like 1 GW, 95% availability, steerable down to 0.6 GW”. Solar right now goes “weeell, not really my problem what you want - I can give you power sometimes and sometimes not”.

So like coal power socialises the cost of pollution, renewables socialises the cost of consistency.

We could instead say “storage is the solar field operators’ concern” and then you’d be able to see what solar really costs”.

And hear me right; I’m ALL in on renewables. I’m also ALL in on nuclear. We need everything that can deliver power with low carbon output. If nuclear goes away, you’ll have to start a tonne of gas peaker plants when there’s not enough wind and not enough sun to power everything.

It’s a mix, not a battle. Kill nuclear and you pretty much kill decarbonisation.

The underlying issue with energy is always storage. That has always been the appeal of fossil fuels and now nuclear.

Shelf stable energy ready to be unlocked in a rock or liquid that nature provides right out of the ground.

fantastical technology

Ah, the "fantastical technology" of the 1950s.

It's only prohibitively expensive the way that we're currently doing it in the US, there are better ways.

Unless you're in Epstein Land of America where coal is now the golden standard for the predator administration

Coal is for cowards, burn whale blubber and trees

I have solar power at home in the USA. I just set it up by myself without asking permission.

Turns out the sun has a few competitive advantages over nuclear: free fuel, no radioactive waste, and it doesn’t need a decade of permits before it starts shining. The real bottleneck now is grids and storage. Imagine losing the energy race to a giant fusion reactor 93 million miles away. 😎

It has its issues, but yeah currently it is the cheapest source of power, it got so cheep that individuals can build their personal power plant for their home.

And we still have idiots fighting it. Even if you don't care about environment (you are "drill baby drill" kind of person) it still makes sense economically.
