Yet, what is the government doing?
Pushing ethanol. Alas, energy-wise it takes about a gallon of ethanol to make a
gallon of ethanol. Biodiesel is a little better, but only a little.

You get about 1.3 units of energy for each unit of energy invested in ethanol. You get about 2 units with biodiesel. If every patch of ground were put in biofuel production we could supply about 17% of out total need for motor fuels. That would leave no land for food production. Meanwhile climate change is making some areas not quite as friendly to crop production as they were.
