Hmm, oxygenated - ok.
The higher volume of consumption required to deliver the distance is quoted in this thread at 5% by at least one person.
I wonder if the extra trucking (due to volume, you get less kM), is made up (I realise the USA is a bit different to Australia in terms of population density - so trucking of fuels must be longer here).
I still think food is an issue though - we burn more fuel, we have a thirst for even more, the price of ethanol rises due to supply/demand, farmers want in on the action so give up other producing activities (think cattle), and go straight for Ethanol!
If you can find it, check out Future of Food, specifically the scene in India where a village is shut out from public farming land whilst it's used for fuel producing activities.
I don't ever proclaim to fully understand production of Ethanol, I thought my post made for further discussion on Ethanol and merely put forward what I believed were facts.
I won't be using Ethanol - both, my Pulsar and Sonata are not compatible (see list for Australia here
Can my vehicle operate on Ethanol blend petrol? : FCAI). The one time I did put Ethanol in the Sonata, the fuel gauge went bonkers.
