I have found that the answer to this question, even assuming some of the rosier productivity numbers for cellulosic ethanol, to be useful context for this debate. The numbers that I’ve seen illustrate the enormousness (and enormity) of our demand, and indicates the importance of prioritizing improvements in transportation efficiency first. Others may obviously draw different conclusions.
