Ethanol agriculture is really inefficient land use. There isn't enough land on the planet to grow enough crops to supply ethanol for the entire world to use. And spoiler alert: ethanol actually emits more CO2 than fossil fuels when you include production, refinement, and blending. Okay, if everything was running on ethanol, sure, we'd cut CO2 emissions by roughly half, but then we're back to that pesky land issue.

As for EV's, batteries take enormous amounts of energy from the mining and manufacturing. At best, comparing lifetime emissions (resource mining, manufacturing, use, and scrapping), it's basically a wash with a typical ICE vehicle. Add to that the fact that they're about 30% heavier than their ICE equivalents (because batteries are so damn heavy), it means they'll wear down roads faster (causing more emissions to extract resources, construct and maintain roads) and wear tires faster. Oh, and fun fact: tires are actually the biggest polluter in any road vehicle.

Ideally, you'd use agricultural by-products for ethanol/biofuel production.

Granted, we're not there yet, but it would be a more worthy goal.
