Ethanol: It's about Big Corn!
And why is it you are overlooking Sugar Beets?
"Big Corn"!?!?
ROFL...
Sorry, but American corn is overwhelmingly produced by family farmers.
And unfortunately, historically, way too much of it has been sold for a pittance, and ended up going down the Mississippi River on barges, for export to other countries to feed THEIR livestock.
It's much better to add value at home, by turning corn and soybeans into meat, and NOW, energy as well.
I love seeing the Midwest dotted with ethanol plants, mostly built and owned by family farmer-owned Co-ops, dotting the Fruited Plain.
