Wrong. You are are assuming that is 24/7/365 You are also omitting the transmission costs Solar at best is available for 6-8 hours and it is intermittent during that period. So it averages a fraction of that and has large variances 1 sq km cannot power 500k houses How does that compare to coal/gas/nuclear, the output of these 3 modalities dwarfs wind and solar Offshore wind? That is pure folly and environmental destructive
Here is a basic comparison comparing wind with coal. Coal wins hands down. Nuclear does far better
