Biomass refers to the organic material that is used for production of energy. This energy production process is referred to as Bioenergy.
The main purpose of investigating biomass energy is to find sustainable, renewable energy in order to eliminate the usage of fossil fuels reducing carbon dioxide emissions.
Biomass energy can be used in many ways, and made from many sources. Historically in the United States, it has come from three primary sources: wood, waste, and alcohol fuels. More recently, it has come from corn as well. It can also come from plants like switch grass and hemp. Biomass energy can theoretically be made from any material that is, or was, living.
