Exactly! There is zero net environmental benefit to adding ethanol made from corn to the fuel in our car gas tanks. Zero.
It may line the pockets of people in corn growing states but that’s where all benefit ends.
It's worse than that. A Cornell study showed that for each gallon of corn ethanol produced it took 131,000 BTU's of mostly fossil fuel energy. The BTU value of a gallon of ethanol is 77,000, so it's a substantial net energy loss. I've lost two, 2stroke carburettors, to that c*ap and avoid it wherever possible.
