Intermittency and transmission at scale are likely to be exceedingly expensive and impacted by NIMBYism as wind and solar continue to scale towards world scale.

Intermittency and transmission at scale are likely to be exceedingly expensive and impacted by NIMBYism as wind and solar continue to scale towards world scale. Nuclear runs 24/7 and requires a lot fewer wires (since the plants are centralized) and so fits well into those downsides. Of course nuclear has downsides too, obviously, but there's plenty of reason to believe that, if nuclear people can start delivering projects on time and budget, that there's room for a massive expansion of carbon-free 24/7 nuclear power.
