Biofuels

Biofuels are non-fossil fuels. They are energy carriers that store the energy derived from organic materials (biomass), including plant materials and animal waste.

They may be solid, such as fuelwood, charcoal and wood pellets; liquid, such as ethanol, biodiesel and pyrolysis oils; or gaseous, such as biogas.

Often the term biofuel is used in a narrow sense to refer to liquid biofuels for transport.

First-generation biofuels are currently produced from food crops such as sugar cane and rapeseed. They include bioethanol (made from sugars and starch) and biodiesel (made from vegetable oil).

Second-generation biofuels are under development and will be derived from non-food plant matter such as crop residues and agricultural or municipal wastes. They include bioethanol made from cellulosic materials such as straw or wood.
