They list the project area as 4600 acres = 7.16 sq.miles
I recall a few talks, where it was stated " a solar area 100miles x 100miles (10,000 sqmiles) would collect all the energy needed by the whole country.
10,000 sqmiles / 7.2 = 1/1389th (0.07% )
we just need 1389 more solar farms this size. {and just need to build 53 of these per year for 26 years...}
Put another way, this solar installation has 1.9 million PV panels, and to build out 1389 more installations of this scale would need a total of 26.4 billion PV panels. (worldwide PV production is about 1 billion panels per year) it would take at current production rates, 26 years to build just the PV panels needed for the USA, alone. If USA energy use is 16% of the world total, then 6x the 26.4 billion PV panels are needed worldwide. About 162 years of 2023 rate of PV panel production.
Put another way, the Installation was quoted to cost $1.7 Billion (including the large ESS and PV)
to build 1389 more of these, at the same cost is about $2.3 Trillion. 10% of the USA annual GDP - spread over the 26 years it would take to produce the PV panels (at current world production rates) this would amount to 90 billion per year. Yes, costs would change over a 26 year period, costs would also scale if 53 installations this size were built per year, every year, for the next 26 years. In 26 years we would be due to change out the PV from the first built installations with new panels.
The 162 years of (2023) production to build out the energy needs of the entire world would cost in the order of 14.5 Trillion, or 14% of the world Annual GDP, ie spread over 162 years, the cost is about 1% of world GDP per year.
