Technology connections did a barn burner video on solar, and opted to do some testing on farmland use. In his comparison, he looked at 100 acres of ethanol corn farmland, i.e the farm land used to only add ethnol to gasoline.
He found that compared to the fuel produced by the single yearly harvest of corn, that the electrify generated by solar panels on it would allow EVs to cover 70x as much distance, and that was assuming the worst case in EV fuel efficiency. Thats how wildly inefficient we use "prime farmland" now to make gasoline additives, but nary a peep is heard about that for some reason.
Another calculation he did? He also found that if we just used ethanol corn farmland, just the land that makes gas for cars in a thinly veiled farmer subsidy program, and covered them with solar panels instead, we could produce 7x the total energy demand of the entire United States. Seven. Times.
This of course ignored interconnects, storage , georgraphy and what not, but the scale is so unimaginable, that they almost don't matter. If we just eliminated gasoline handouts to farmers and slapped solar panels on that land, we could power all of america with solar and use not 1 square foots of other farmland.
The farmland/scale debate is agitprop. Its noise to make excuses to not use the cheap, magic energy machines that make power for free for decades and instead to keep paying oil companies trillions, forever.
