An Ethanol Success Story?

I’ve been having an e-mail dialog with a reader about the wide-spread adoption of Ethanol (from sugar cane) in Brazil (“As Brazil Fills Up on Ethanol, It Weans Off Energy Imports”), and their ability to reduce dependence on petroleum.

The national will and industry to pull this off are impressive.

The question I have, on which the article is silent, is whether production of sugar cane in Brazil is sustainable or not? Is it grown as a monoculture as corn is in our midwest? What inputs does it need?

It would be great to have an example of sustainable biomass production being used for ethanol.
