Biomasse refers to organic materials derived from plants and animals that can be used as a source of energy. This includes agricultural residues, wood, and even animal waste. Biomass can be converted into biofuels, such as ethanol and biodiesel, which can replace fossil fuels in various applications, including transportation and heating. Using biomass for energy has several benefits, including reducing greenhouse gas emissions and promoting sustainable energy practices. It can help decrease reliance on non-renewable resources and support local economies by utilizing regional agricultural products. However, careful management is essential to ensure that biomass production does not negatively impact food supply or ecosystems.
