I'm a biotech student who's very interested in this stuff. For anyone looking for an expanded explanation of the challenges facing cellulosic ethanol this blog post might be interesting. I've also written about the possible affects that large scale biofuel production may have on food security.
Cellulosic ethanol would be a big contribution to solving the impending energy crisis. Domestic waste and agricultural waste could be recylced into fuel to supplement demand to some extent, but in order to meet demand grain originally destined for food would have to be diverted. If not regulated properly this would likely cause an increase in global food prices. In a world with circa. 1 billion people starving, this is obviously less than ideal.
