Delta-T said:isn't Brazil using cane sugar to produce the ethanol? this is more efficient as far as I know (higher yield). They just happen to have the right climate for it. We might be able to make the same thing happen with beets, but I dunno how intensive that is. Any beet farmers on the forum?
There are lots of options for feed stock. From corn to switch grass to beets and sugar cane (down south). The current problem with those options are the logistics. We raise corn and beans. Lots of them. We have the infrastructure to deal with it. Many changes (and expensive ones at that) would need to be made to change over to another feed stock other than switch grass. Most farmers can still bale the stuff.
