Biofuel is a product produced from biomass. As the biofuel definition above suggests, this fuel is considered much cleaner than petrol/diesel alternatives. Biofuel is considered carbon neutral, as the biomass absorbs roughly the same amount of carbon dioxide during growth, as when burnt.
The important difference between Biofuel and fossil fuels, is that Biofuel is renewable. Fossil fuels are in imminent danger of running out, or becoming economically non-viable. Biofuel can be produced from a number of different compounds including proteins, fats, and alcohols.
