Underappreciated: US farmland *already substantially produces energy, not food*, and does so very inefficiently. Corn ethanol (~40% of all US corn) requires about 100 times more land per vehicle-mile driven than solar photovoltaics -> electric vehicles. Shifting corn to solar *would free up land*.
anytime people raise concerns about land use for solar projects or anything like that i just want to point out that half the corn we grow in this country gets used to make gasoline slightly worse
