--Interesting. I see a number of sources like national corn growers association, etc. Which I would not trust too much either. What I'd like to see is a pilot plant that runs the whole process from planting, fertilizing, harvesting, distilling, etc. on ethanol from corn with a net energy gain. It all depends on your assumptions.--

Did you read their criticisms of Mr. P's assumptions?

Obviously not all of them, but those I did read were very scant on hard data. And a wildly optimistic claim of 67% net energy gain (from one of them) was too much for me to believe either. There was an analysis in Car and Driver a couple of months ago that was pretty unbiased that came to conclusion that even with a reasonable net energy gain of 18-20% that ethanol wouldn't do much good
