In rural areas where the livestock breeding is done, biogas can be produced by making biogas plants. It is inflammable gaseous mixture in which mainly methane, carbon dioxide, carbon monoxide, nitrogen and oxygen gases are found. The thermal value (heat producing capacity) of biogas is more than that of kerosene and dung cake. This energy can be converted into electrical energy, thermal energy and used as cooking fuel.
