Prior to the first industrial revolution, people were scarce and resources were
plentiful. Now confronted with the opposite circumstance, humanity must mount a
second industrial revolution featuring population stabilization, increased energy
utilization efficiency, and adoption of new renewable and sustainable energy supply
technologies.        Biofuels have been hailed by some as a key component of this
second industrial revolution, and have also been criticized by others as a meritless
scam. Amidst these disparate evaluations, it is difficult for policy makers and the
public at large to know what to think. This presentation will address key issues
associated with the feasibility and desirability of cellulosic biofuels used on a large
scale - including energy balance, land competition, carbon debts, and resource
availability - with a focus on two questions: 1) understanding the reasons underly-
ing the different conclusions reached by different analysts, 2) identifying paths by
which large-scale biofuels use would be feasible and desirable. The talk will close
by commenting on the general applicability of lessons learned from the biofuel
example.
