Chat-GPT says solar is extremely more productive in terms of energy opportunity per acre compared to corn for biofuels.
There are over 29 million acres farmed for biofuel production.

Anyway, this is very unintelligent, all around. And that is polite.
Chat GPT Answer:
Short answer: solar absolutely crushes corn-for-ethanol on an energy-per-acre basisâ"by roughly 35â"45Ã-- each year.
Why (using U.S. medians):
Corn â' ethanol: Typical yields are ~460â"480 gal ethanol/acre/yr (e.g., 462â"484 gal from University of Nebraskaâ"Lincoln extension). Ethanolâ(TM)s energy content is ~76,000 Btu/gal. Thatâ(TM)s about 10.3â"10.8 MWh (thermal) per acre per year.

Solar PV: Utility-scale solar delivers about 394â"447 MWh of electricity per acre per year (nationwide median energy density from Lawrence Berkeley National Laboratory / DOE).

Comparison (annual, per acre):
Corn ethanol: ~10â"11 MWh (thermal).
Farm Energy

Solar PV: ~400â"450 MWh (electricity).

Ratio: Solar yields â 35â"45Ã-- more useful energy per acre.
Notes:
This ignores ethanol co-products (animal feed) because the question is about energy per acre.
If you convert to miles driven, the gap widens further because EV drivetrains use electricity much more efficiently than internal-combustion engines burning ethanol. (Same acreage â' far more vehicle miles with solar-powered EVs.)
