Biomass

Using biomass as fuel seems like a good idea because there are so many sources of raw materials. Biomass comes from animals, plants, and even trash. It includes manure from livestock, trees, grass clippings, and crops. Major biomass crops include corn, sugarcane, soybeans, and sugar beets. Some biomass, like wood, is burned directly. Some is processed into biofuels. Either way, we use biomass because it has stored energy. But, where does the energy in biomass come from? It all starts with plants and photosynthesis.
