Renewable organic materials, such as wood, agricultural crops or wastes, and municipal wastes, especially when used as a source of fuel or energy. Biomass can be burned directly or processed into biofuels such as ethanol and methane. An example of biomass is plant material that produces electricity with steam.
How it works
We use four types of biomass today—wood and agricultural products, solid waste, landfill gas and biogas, and alcohol fuels (like Ethanol or Biodiesel). Most biomass used today is home grown energy. Wood—logs, chips, bark, and sawdust—accounts for about 46 percent of biomass energy.
