For onshore wind, probably wind.

For offshore wind, not nearly as clear. The US still lacks a lot of the specialized vessels, ports and manufacturing capacity.

Solar has bigger upstream dependence on Asian wafer/cell production.

Forgive the ignorance, what drives the demand for offshore wind instead of on land anyway? Shorter power run to coastal cities vs longer transmission loss from exurban environments?

And with solar, I can't imagine that would be fast to stand up production for... but we're attempting the Herculean task with modern chip fabs. Would panels be harder than that? They both seem existential needs for the future of the country.

Offshore wind is far more reliable than onshore wind. Geography ensures that some ocean locations pretty much always have wind blowing. North Sea wind turbines have a capacity factor of about 60%, approximately double that of onshore wind turbines.

The other advantage of offshore is that it can support the truly massive wind turbines. Onshore wind turbines are a lot smaller.

I have much to learn, thanks!

Maybe we should put the $1.2B into that sort of thing, then?
