Electric power demand will increase by what it takes to keep our cars charged up, and to drive industrial production of hydrogen for steel and other industrial processes, ammonia for fertilizer, synthetic fuels (including ammonia and hydrogen) for bigger vehicles, carbon capture from the atmosphere, water desalination, and myriad other uses.

Build-out of renewables will increasingly displace fossil-fuel generation, then (as that is exceeded) bank energy in storage systems (batteries and pumped hydro, short-term, other tech for longer term). We will need a lot of new transmission lines to trade power between current users, current generators, and storage.

None of it requires new physics, although improvements in catalysts will improve round-trip efficiency and cost of storage systems and synthesis, and new chemistries will improve cost and efficiency of new photovoltaic build-out.

There is no place for nukes in that world. They cost way too much to compete on a fair playing field.
