Biomass energy is a renewable energy source derived from organic materials like plants, agricultural waste, and animal byproducts. It is produced through methods such as combustion, gasification, anaerobic digestion, and fermentation to generate heat, electricity, or biofuels. Key benefits include sustainability, waste reduction, and carbon neutrality, though challenges like land use competition, emissions, and high initial costs exist. Biomass energy offers a promising path toward a cleaner, sustainable energy future.
