Biofuel subsidies might make sense, other critics say, if they favored “cellulosic” ethanol instead—fuel that comes from breaking down the cellulose in the fibrous parts of the plant, such as the corn stalk instead of the kernel. That wouldn’t put direct pressure on food prices, and might even reduce them by providing a market for agricultural waste products. Cellulosic technology is also the key to exploiting such nonfood plants as switchgrass,...........

Growing switchgrass uses land just like growing corn. Switching from corn to switchgrass will have exactly the same effect on the price of food.
How about kelp from the ocean?
What if you used hemp?
