For an answer, look at:
A desert area 10 by 15 miles could provide 20,000 MW of power, while
the electricity needs of the entire U. S. could theoretically be met
by an area 100 miles on a side.

Spendy commercial PVs exist as is at 27.5% solar efficient (that's
roughly a terrestrial net average of 50 w/m2).  Those numbers should
get better and even less costly as such PVs get into mass production
(especially if made in China, along with their towers of wind derived
energy that can deliver a footprint worth 40 kw/m2).

So, we need to keep asking ourselves, where's all of that Mook green
hydrogen that's supposedly so dirt cheap and without any end of supply
in sight?
