Biofuel is a term that describes a fuel that comes from biomass. There are solid, liquid, and gaseous biofuels. Biomass refers to biological matter used as a source of energy. Biomass often refers to plant matter. It can be burned for heat or converted to biofuel.  In general biomass can be converted to other forms of usable energy. Examples of biofuel include ethanol and methane gas. Ethanol is often made from corn in the United States. Landfills make methane gas, it is a byproduct of decomposing garbage.
