It takes more than a calorie of fossil fuel energy to produce a calorie of food. From the standpoint of industrial efficiency, it's too bad we can't simply drink the petroleum directly, because there's a lot less energy in a bushel of corn (measured in calories) than there is in the half gallon or so of oil required to produce it. Ecologically this is a fabulously expensive way to produce food.
