Taking Measure of Biofuel Limits


Comment

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.
