About 40% of US corn is used for fuel ethanol [1]. About 90 million acres of corn are planted in the United States [1]. So around 36 million acres of corn are used for ethanol. Solar farms generally require less than four acres to produce one GWh of electricity per year [2]. Therefore at least 9 million GWh of electricity per year are available by displacement of corn ethanol alone. Total annual US electricity consumption is presently around 4 million GWh [3]. In summary, "the assertion" is false. 1: https://www.ers.usda.gov/topics/crops/corn-and-other-feedgrains/feedgrains-sector-at-a-glance/ https://www.ers.usda.gov/topics/crops/corn-and-other-feedgra... 2: https://www.nrel.gov/docs/fy13osti/56290.pdf https://www.nrel.gov/docs/fy13osti/56290.pdf 3: https://www.eia.gov/energyexplained/electricity/use-of-electricity.php https://www.eia.gov/energyexplained/electricity/use-of-elect...
