Biofuels better for Nature? Maybe not!
Depending where you are in the world you might notice signs touting the 5% ethanol in the gasoline you are buying. The idea is that biofuels [currently primarily made from corn] are better for the environment. As it turns out that might not be the case.
A new study in the journal Nature Climate Change suggests that one particular source of biofuel, corn residue [the stuff left over from corn production], should not and cannot be used to meet the new US federal mandate to ramp up ethanol production and [ideally] lower greenhouse gas emissions.
