The way I hear it, a Cornell study made calculations assuming all
ethanol comes from corn grown on fields requiring irrigation, which is
only 15% of all American corn.
It appears to me that the valid points against biofuels are mainly on
bidding food prices higher.

It is clear that food not grown here is going to have to be replaced--
grown elsewhere. And, those new farmers will have to clear land &
destroy habitat to do that. (I suppose that should've been 5c.:
destruction of forest / grasslands / habitat.)
Since ours is among the most productive farmland in the world, chances
are the new land will be less fertile. And so it'll take more land
area and more work and tractor fuel, on average, to yield the same
crop.
And the replacement's agricultural practices aren't likely to be as
advanced and efficient as ours in general.
What the total affect of those factors is, I haven't calculated; I was
just passing on that link (to the fellows who have, who estimate
ethanol's net effect is to double CO2 emissions).
Best wishes,
