[Keith in Iowa]

You didn't read anything at that last link I provided, did you? If you had, you would not be making such an ill-informed comment.

And...

co·prod·uct n. A product produced together with another product.

Ethanol is but 1 coproduct of the process of making ethanol.

I did read ... enough. You did notice that I posted content from it? My "ill informed comment" was taken from that link.

It is ridiculous to claim that ethanol production is a co-product of corn processing and therefore should only be charged with the energy that was used to turn it into ethanol. The fair "charge" would be calculated as follows: compute the value of the labor and materials and subsidies that go into growing a bushel of corn. Then add in the labor and materials and subsidies that go into converting that bushel into ethanol. Attribute that total cost to the ethanol in proportion to its economic fraction of the result. *That* is fair.

You grow corn Keith? Work for ADM or something?

All of the products your link shows, require additional processing, something the link didn't include.

state of the art farming?
state of the art distilling?

Sure sounds like increased costs to me.
