which is a source of biomass energy
1. What is biomass and how is it used for renewable energy?
Biomass refers to organic material derived from living or recently living organisms, such as plants, trees, and animal waste. It can be used for renewable energy as a sustainable alternative to fossil fuels. Biomass can be burned directly to produce heat or used to generate electricity through thermal or biochemical processes.
Comprehensive Answer:
- Biomass is a renewable energy source that is derived from organic materials.
- It can include agricultural and forestry residues, dedicated energy crops, algae, and organic wastes.
- Biomass can be used to produce heat, electricity, or biofuels.
- When burned, biomass releases carbon dioxide, but it is considered carbon-neutral because it absorbs the same amount of carbon dioxide during its growth as it emits when burned.
- Thermal processes involve direct combustion of biomass to produce heat, while biochemical processes use bacteria and enzymes to break down organic matter and produce energy-rich gases.
- Biogas, bio-oil, and solid biomass pellets are some examples of biomass energy products.
- Biomass energy helps reduce greenhouse gas emissions, stimulate rural economies, and diversify energy sources.
