Biofuels are not an answer for reducing CO2 emissions [via Gabriel].
The conclusions deal a blow to what are known as cellulosic biofuels, which have received more than a billion dollars in federal support but have struggled to meet volume targets mandated by law.
They actually increase CO2 emissions:
A $500,000 study paid for by the federal government and released Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7 percent more greenhouse gases in the early years compared with conventional gasoline.
It looks more like cronyism than environmentalism to me.
