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.
