Ethanol is unlikely to be the best choice, all things considered,
regrdless of choice of feedstock or production methods, but it's by no
means as poor as some anti-ethanol campaigners assert.
Making it from corn (apart from the waste residues) is dumb, but
raising it from biomass waste, or from algae or switchgrass or
miscanthus or even sugar cane is defencible. Butanol however is almost
certainly a better fit with the existing trans****t fleet.
