Biofuels better for Nature? Maybe not!
Food or Fuel? The great debate, but ethanol from corn is not the savior it was thought to be.
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.
