What is biomass? Biomass is a widely existing substance on the earth, not only including animals, plants and microorganisms, but also other organic substances derived, excreted and metabolized by these living substances.

Each biomass has energy. Taking biomass as a carrier, the energy produced by biomass is biomass energy. Biomass energy is mainly a form of energy that solar energy is stored in organisms in the form of chemical energy, which is derived from the photosynthesis of plants. The energy consumed by the photosynthesis of plants on the earth accounts for 0.2% of the total radiant energy of the sun shining on the earth.

Although this ratio is not large, it is worthy of shock because the energy consumed by photosynthesis is 40 times the current total energy consumption of people. It can be seen that biomass energy is a great energy source. The main sources of biomass energy are firewood, livestock manure, sugar crops, urban sewage, and aquatic plants.
