I've worked on energy crops and bioenergy conversion systems for 20 years, and from a practical standpoint, we need to use marginal farm land because those are the lands that are really in surplus and are providing low income to farmers. We can increase those farm receipts from that farm land, and if we strengthen the overall demand from the farm sector, we help all the commodities like canola and we can produce appreciable amounts of energy. Utilization of wastes can be a good thing, but crop residues really aren't waste; they do feed the soil and protect the soil. So we have to do that judiciously.
The Obama strategy of supporting the sustainable use of crop residues and wood residues and energy crops I think is brilliant because it takes the government out of the business of picking technology winners on the conversion side and it's a safe investment because you're investing in energy and helping support it broadly for conversion technologies.
