Ethanol mandates for gasoline are now a third rail subject. No politician from either side of the isle is going to touch them for fear of retribution from the Corn Growers associations.
Not really.
Gas is cheap enough (inflation adjusted) that ethanol is not the new hotness anymore. EV’s are.
What is left are the smaller plants that are making it for feed lots (DDG is good cow feed), and the wet mills that are using it to control byproducts.
And for the “Grow food”, grow what? I see a lot of city people rail against corn, and no one really understands why corn is grown. It is the most carbs per input cost out there. That and the demand for say, carrots is many factors smaller.
