Answers
Answer:
Biomass is organic material that comes from plants and animals, and it is a renewable source of energy.
Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat. Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels.
Examples of biomass and their uses for energy
Wood and wood processing wastes—burned to heat buildings, to produce process heat in industry, and to generate electricity
Agricultural crops and waste materials—burned as a fuel or converted to liquid biofuels
Food, yard, and wood waste in garbage—burned to generate electricity in power plants or converted to biogas in landfills
Animal manure and human sewage—converted to biogas, which can be burned as a fuel.Biomass fuels provided about 5% of total primary energy use in the United States in 2018. Of that 5%, about 46% was from biofuels (mainly ethanol), 44% was from wood and wood-derived biomass, and 10% was from the biomass in municipal waste. Researchers are trying to develop ways to use more biomass for fuel.
