And Brazil is particulary well suited to ethanol production, having the right climate for producing a superior feedstock (compared to corn), sugar cane, that can be produced cheaply on vast swaths of slash and burn former rainforest (ie, at great cost to the environment in the long term). And it still isn't really an economical proposition. I remain highly skeptical of the value of ethanol as a fuel, at least with any currently-known production methods. Otherwise they wouldn't need subsidized corn and subsidies for ethanol production to encourage it.
