...biofuels for some time, arguing that biofuel production takes valuable agricultural land away from food, driving up the price of staple crops like corn. But the Science papers make a more sweeping argument. In their paper, Fargione's team calculated the "carbon debt" created by raising biofuel crops - the amount of carbon released in the process of converting natural landscapes into cropland. They found that corn ethanol produced in the U.S. had a carbon debt of 93 years, meaning it would take nearly a century for ethanol, which does produce fewer greenhouse gases when burned than fossil fuels, to make...
...actually available right now, but the evidence suggests we be better off not relying on them. But even Fargione doesn't argue that we should ditch biofuels altogether. Biofuels using waste matter - like wood chips, or the leftover sections of corn stalks - or from perennial plants like switchgrass, effectively amount to free fuel, because they don't require clearing additional land. "There's no carbon debt," notes Fargione. Unfortunately, the technology for yielding fuel from those sources - like cellulosic biofuels - is still in its infancy, though it is improving fast. In the end, the right kind of biofuel...

...Even further, this is a man, who despite his current popularity among progressives, underwent a good amount of liberal scrutiny as well—from free trade to “workfare” to the wars in Kosovo and Bosnia. Indeed, there was a significant element of the Left that was so fed up with the dishonesty and hypocrisy of the Clinton administration that it was willing to vote for Ralph Nader in 2000, knowing full well such the political implications of such...
