The issue with corn ethanol is that while it could* be done without fossil fuels, it isn’t actually. Which is why it is such a scam, actually, because in theory it could be done that way, but it’s cheaper to inject fossil fuels at every stage, and hence isn’t actually green. It was also done before electric cars were a thing, and now the whole thing is a pretty pointless give away to the ag industrial complex.
