Biofuels are not commercially viable

Biofuels have been touted as the fuel of the future, allowing us to continue to use our internal-combustion engines with the products of modern, rather than ancient photosynthesis (i.e. fossil fuels). But is it really 'carbon-neutral' or sustainable as its proponents claim? The raising and harvesting of fuel crops and their refinement into ethanol requires significant energy inputs. Furthermore, since agricultural land is limited, planting biofuel crops will directly compete with food crops. Commercially speaking, are they commercially viable without extensive government subsidies?
