If you need the power to remove carbon dioxide from the air, you do that where the power is. (And there is also chemical storage if you had to transport energy long distance - but a moot point).
The problem is that solar capacity just grows too slowly. We’re growing solar manufacturing capacity as quickly as possible and still fossil fuels remains stubbornly the dominant fuel type for grid energy production in America and barely shifts regardless of how many renewables we add. So from the perspective of “we tried something maybe it’s not working” I’d rather look at the impact scaling up an energy source has on fossil fuels and all evidence suggest that solar has trouble taking over (fossil fuel use and solar energy generated seems uncorrelated whereas it is inversely correlated with nuclear which is what you want).
Why are you so focused on solar, other things like wind are cheap, too? I couldn't care less about what particular energy source is used, I am just making a cost argument. No goal posts are being shifted by me. If you now want to discuss industrial capacity, then, sure, let's discuss how we can somehow build a few hundred nuclear power plants quickly but not expand wind, solar, geothermal or other things quickly.
If there already are cheap technologies, pushing for another one that isn't but might be is a tough proposition.
China built more wind and solar in the first nine months of 2023 than the sum total of all their nuclear reactors under construction, and they have 26. They are likely to build even more over the next nine months. Current estimates are that their emissions will begin a structural decline as soon as next year, because their renewable construction is outpacing demand. Your statement is so far off factually it’s not even in the same universe as reality.
~25B on nuclear weapons (likely maintaining our military arsenal)
~5B on nuclear energy
~27B on renewables
And nuclear requires waaaaaay more for R&D because it’s a more difficult energy source than solar which is scientifically more straightforward & more of an engineering problem that industry is well suited to solving.
No you can’t just plaster solar cells in the middle of some desert because while HVDC has gotten cheaper, it’s still quite expensive and even harder than nuclear tech in some ways to cost reduce. You want to minimize the distance between where you produce energy and where you consume it.
