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.
