Biomass energy or bioenergy refers to the use of a wide range of organic materials as fuels. These are produced by biological processes, and include forest products, agricultural residues, herbaceous and aquatic plants, and also municipal wastes. In principle, biomass is inexhaustible and renewable, provided that new plant life is grown to replace the ones harvested for energy. Biomass can either be burned to produce heat or electricity, or transformed into liquid fuels such as ethanol, methanol, or biodiesel. Biomass has been our predominant source of fuel since well into the 19th century. Whereas dried plants, plant oil, animal fat or dried dung were used for lighting and cooking needs, the most common biomass source was wood. Its dominance was progressively replaced by fossil fuels, first coal and then oil and gas during the 19th and 20th centuries. Today, biomass supplies about 11% of the world's primary energy consumption. Indeed, in many poor countries it continues to be the most important source of energy for heating and cooking purposes, whereas in developed nations only a small fraction of the energy needs are covered by biomass.
