> You claim some hypothetical event with china to cross the plans of global low tech solar/wind energy but ignore the impact on constructions of nuclear power plants, which, as previous comment noted, take much longer to build.
Why should I respond to someone who proposes to build renewable in parallel, while omitting in the same sentence the possibility of building multiple reactors in parallel?
It's a rhetorical game that says enough about the user's goals. I do not intend to stoop to such a level.
> You claim some hypothetical event with china to cross the plans of global low tech solar/wind energy but ignore the impact on constructions of nuclear power plants.
I am not ignoring anything, I repeat, going only renewable implies not diversifying.
That a geopolitical problem could destroy decarbonization goals is a real risk. Or do you want to deny China's total monopoly in the industry?
No energy source is perfect, including nuclear and solar, so stop adding arguments just to overshadow the problems we're talking about.
> "Green" is a perfect propaganda pitch btw.
Well, we can define and use the word that you prefer.
By green I mean a technology whose emissions are low enough to help in decarbonization. Is it better?
Decarbonization is the main issue here.
> The actual problems we try to solve are energy source and waste products. Nuclear energy looses on both aspects, which is why its much more expensive (also including risk/complexity).
As I wrote earlier, the main problem is decarbonization. Secondary problems exist in any kind of energy source.
That the IPCC predicts nuclear growth in most scenarios is quite indicative of its relevance to decarbonization.
So nuclear power is important for decarbonization. And it has been shown over the decades to be a viable option for providing electricity with low emissions. Do you deny this?
Once we accept that, we can discuss how slow and expensive it is, but before then I don't see it possible to engage in an intellectually honest discourse :)
Well, technologically, maybe, but not in terms of location. Previous commenter called it "democratized".
> do you want to deny China's total monopoly in the industry?
No, but that could change. As china did, we can orient towards an electrical future too and there are generator designs without rare earth elements. So chinese dominance is not a given.
> By green I mean a technology whose emissions are low enough to help in decarbonization. Is it better?
I prefer the term "sustainable" and by framing it with energy sources and waste products i am giving you the higher order problem at hand.
> Decarbonization is the main issue
I disagree because my scope is broader. I agree with your statement that NE is "cleaner" than fossil based power plants for now, because as with carbon, its just a matter of scale too.
In an inverted scenario where nuclear waste is the main concern, i could, like you, argue in favor of fossil power.
The path ahead is quite clear, our focus should heavily be on renewables and only tolerate finite energy source as temporary in our transition strategy ... which is something you would deny, i guess.
> No, but that could change. As china did, we can orient towards an electrical future too and there are generator designs without rare earth elements. So chinese dominance is not a given.
True. But looking at the problems we are experiencing in the silicon world, a transition could bring a generalized crisis and quite a long time to return to "current" production levels. We're already struggling now with decarbonization, and China's is just one possible problem that we can't afford on the roadmap. So the priority should be to diversify to minimize these problems
> I prefer the term "sustainable" and by framing it with energy sources and waste products i am giving you the higher order problem at hand.
That's fine, but "sustainable" is a very subjective term. What is the threshold of sustainable? And I bet we have different views and different priorities.

But somehow it seems contradictory to me in some places.
The materials and rare earths from which panels, wind blades and batteries are made are finite. Recyclable, but finished.
Uranium is recyclable from spent fuel, and renewable from the sea.
Then in addition to uranium other types of elements can be used such as fuel, Thorium, Plutonium, etc. (CANDU reactors for example can go with Thorium)
Also this basic argument seems a bit lacking to me, all these energy sources have a finite life, a panel a few decades, a power plant 60-80 years. When new more efficient ways to generate clean energy are discovered they will be used and replaced, we have this now, and it would be better to use them.
Plus, regarding the term "sustainable," and its subjectivity, I find it a priority to minimize the materials required. Because having billions of tons of waste to recycle, it's much harder to control, do it effectively, and in a sustainable way in every corner of the earth.
So I much prefer very small amounts of hazardous material (highly controlled and localized) over endless amounts of inorganic material everywhere.
Plastic, even for noble uses, has already demonstrated the worst of man's carelessness. So nice democratization, but one must also recognize its problems and limitations.
Regarding the word "democratization," however, I see a lot of propaganda in it. Whenever it's used it almost seems like people are naming a divine entity. And all kinds of issues, accountability, feasibility, etc. are omitted. And conversely, any kind of "centrality," is intrensically a problem. I really have a hard time seeing past something of the rhetoric of the "mighty and evil."
