Interesting thought experiment - for the same capacity, we’d need 2300 sq.mi of photovoltaic gross land[1], assuming we need to way overbuild let’s make that 3x (6900 sq. mi). That’s equivalent to ~15% of Mojave desert being covered in solar and not accounting for battery storage needed.

That same capacity would require 26 Diablo canyon equivalent stations or only 30.5 sq.mi. [2]

Of course, Greater Los Angeles area itself is 33,954 sq.mi, so if we assume 10% of that are roofs, parking lots and other structures that can be covered with a solar panel setup somehow (big assumption, but this is a thought experiment after all), we’d have close to 1/2 of the total already covered. Add other populated areas in CA and things don’t look so outlandish with some combination of Nuclear/storage/solar.

The big question is whether we have the social cohesion to pull this off or not. The train from LA to SF mess has me worried here…

The initial quote is for "heat" energy. To get that into electricity in a steam turbine you lose about 2/3rds of it.

Pretty sure modern steam conversion is now over 50%, should be higher for super heated. It's come a long ways.
