Evidence, please? Where are the enzymes or bacteria for cellulosic ethanol or biodiesel in commercial quantities and prices. IIRC, shale oil was supposed to be viable at $70 per barrel, and Alberta's tar sands was similarly priced. CL, NYMEX is the symbol according to Yahoo.

They were already building pilot plants - at $70/bbl oil. At sustained $100/bbl they will no longer be pilot scale.
