The term "biomass" refers to organic matter which can be converted to energy. Some of the most common biomass fuels are wood, agricultural residues, and crops grown specifically for energy. In addition, it is possible to convert municipal waste, manure or agricultural products into valuable fuels for transportation, industry, and even residential use. There are an uncountable number of woodstoves being used to produce heat for buildings or for cooking in the world, making biomass one of the most common forms of energy. Utilities and commercial and industrial facilities are also using biomass to produce electricity. It is such a widely utilized source of energy, probably due to its low cost and indigenous nature, that it accounts for almost 15% of the world's total energy supply and as much as 35% in developing countries, mostly for cooking and heating. We have used bioenergy, the energy from biomass (organic matter), for thousands of years, ever since people started burning wood to cook food or to keep warm. And today, wood is still our largest biomass resource for bioenergy. But many other sources of biomass can now be used for bioenergy, including plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes. Even the fumes from landfills can be used as an energy source
