According to an Ernst and Young analysis, things are getting a little gnarly out on the biofuels frontier. From Platts:

The global biofuels industry has seen a slowdown in growth over the third
quarter of 2007, caused by rising feedstock prices and a rapid expansion in
capacity that may outstrip demand, according to an Ernst & Young report
released Friday....

The industry is also being hampered by the high-profile debate over the
potential conflict of first-generation biofuels on food prices and
sustainability concerns, the report said.
