This article raises some very important issues. But it does not estimate what percentage of the current energy of fossil fuel use could be replaced by biofuels. One number I recall is that one year of petroleum consumption equals 400 years of total biomass production for planet Earth. So biofuels will be a drop-in-the-bucket, even if the global population and economy sink to much lower levels.

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.
