Quant aux biocarburants, l'OPEP sait que la substitution n'est pas possible. Ils ne représenteront jamais plus de 10 % de la consommation mondiale. Cela ne devrait pas lui donner de cauchemars.

I'm afraid OPEC has that one right.

I've tried to educate myself a bit over the past year on biomass / biofuel and I've come out of it fairly depressed.

It looks technically plausible. Some things may actually work like the thermo-chemical approach. For instance, see Range Fuels (don't lose your time on their website. It's near 100% marketing fluff).

But the business / investment / political reality looks downright awful. I just don't see how biofuel can reach the critical mass where they'll be able to resist anti-competitive actions and stand on their own.
