Biofuels in Transportation: A World Prospectus
by John Laumer, Philadelphia on 06.13.06
Worldwatch Institute and it's partner organizations have just published the epic: “Biofuels for Transportation: Global Potential and Implications for Sustainable Agriculture and Energy in the 21st Century” TreeHugger is pleased to promote this seminal work for several reasons. The study is circumspect and forward-looking. It sets a baseline for understanding choices for public policy development and private investment. And, joint sponsorship by a consortium makes it harder to spin. Finally, it gives those of you who love to comment on this stuff (you know who you are) a chance to be as happy as kids at a party for awhile. So without further ado, click down and have a look at some cool graphs and then download the extended report summary from Worldwatch. You’ll be glad you did.
You're required to create an account in order to download the report summary.

Thanks for the great work!!
The biodiesel chart above is missing what is by far the highest yielding feedstock: algae. Valcent claims that its test bed facility is producing oil at the rate of 4000 barrels per acre-year (second link below).

Besides offering higher yield potential, taking up C02, and using human wastewater as a nutrient source, algal oil cultivation is easily "industrialized". That said, there are no pre-commercial ventures yet and bench scale projections such as this will be imprecise. Fingers crossed.
