>>12266407Ok, so I did a bit of digging and revised the calculation.
So, there are many different pv cells of varying efficiency
India's Solar Farm has a net capacity of 2000MW at 50km^2
China's largest Solar Far is 2250MW at 100km^2
Topaz is at 550MW at 19km^2
India used more efficient solar cells and costed them $1.5B
China used inefficient and costed them $500M
Topaz costed $2.4B
Kashiwazaki-Kariwa Nuclear Power Plant costed $7B but produces 8000MW.
Thus, if we used their techs, it would cost India $6B and 200km^2 to match it
China would need $2B and 400km^2
USA would need $34.8B and 275km^2
All of which would die in 20 years
By all accounts this is absurdly more expensive than Nuclear which can survive for 80 years before the radiation in the facility becomes too high
