WELL, YES: “An international group of food scientists says countries should not use food crops to produce biofuels during a world food crisis. . . . Instead of using grains, the international group is calling on the U.S. and other countries to shift biofuels production to nonfood crops such as switchgrass.”

But, actually, as some critics are trying to tar all biofuels as if they are made from corn, this is a point worth stressing. Crop-based biofuels are just votebuying from farmers, but others are worth pursuing.

UPDATE: In response to questions, switchgrass grows on marginal lands that aren’t really suitable for food crops. And Bob Zubrin says it’s possible to make enough ethanol and methanol to replace OPEC’s output using only agricultural waste.
