Coal, kerosene and petroleum are nonrenewable while biomass is renewable source of energy. The term “biomass” is especially useful for plants, where some internal structures may not always be considered living tissue, such as the wood (secondary xylem) of a tree. Biofuels include bioethanol, biobutanol, biodiesel & biogas. Biomass is grown from several plants, including switchgrass, hemp, corn, poplar, willow and sugarcane. The particular plant used is usually not very important to the end products, but it does affect the processing of the raw material. Production of biomass is a growing industry as interest in sustainable fuel sources is growing.
