I agree with much of what Stan says above, but we're all whistling through the graveyard in some respects. The electric vehicle market share will increase during our lifetime, but not without attendant problems of waste streams, recapture of harmful components, etc.
When ADM scientists figure out a way to grow corn to make batteries, Armageddon will truly have arrived, and ADM may switch over their currently-for-sale ethanol plants to EV-related battery production.
China will remain the big dog in the energy business, both short and long term, regarding both ethanol and EV's, with their pollution problems, current trade war build-up, and willingness to spearhead ecologically disastrous industrial practices.
99% of the corn grown in the US is not for human consumption. It's not just Chuck Grassley or the family farm owner who's worried about market-based macroeconomics. Where do we sell the corn and beans we can no longer use with current Chinese tariffs? We should all be glancing at the pundits because we all have a dog in the fight.
