While looking for something else, I did find the reason I pay little
attention to Pimentel and his lonely crusade against the energy balance
of alcohol fuels (and apparently sometimes biodiesel, which is quite
insane).  It's not particularly ethical to leave questionable research
unchallenged, but this thread is more or less dead so I'm simply going
to give a link to a listing of many other studies that always seem to
contradict his position:
