Basic information about biomass: raw materials and processes for biomass energy generation, energy content of various biomass resources, and uses for biomass energy. The term biomass refers to raw organic material used to generate a number of energy resources, including heat, liquid or gaseous fuels, and electricity. Chemical energy stored in biomass can be converted to heat through combustion (burning). Biomass can be converted to liquid or gaseous fuels or can be used to generate electricity in the same way that coal is used. The electricity generated can be sent to energy consumers via electric transmission systems.
