I have discussed that issue here before. Actually, it would take much 
more than "the entirety of our agricultural surfaces" in the U.S. It 
would take roughly twice as much as the entire landmass produces -- 2 
times all biomass from all dry land.

Biomass can never supply more than a few percent of our energy, and 
every calorie of biomass we use condemns someone outside the United 
States to malnutrition and starvation.
