They are used to partially or completely replace petroleum-derived fossil fuels. Kinds of biofuels include solid biomass, liquid fuels and biogases. Specific examples include bioethanol, made from sugar and starch crops, and biodiesel, made from vegetable oils, animals fats and other recycled greases.
