Biomass fuels are renewable energy sources made from organic materials, such as plants, agricultural waste, and animal manure. These materials can be converted into energy through processes like combustion, fermentation, or anaerobic digestion. Biomass fuels can help reduce reliance on fossil fuels and lower greenhouse gas emissions. Common types of biomass fuels include wood pellets, bioethanol, and biodiesel. They can be used for heating, electricity generation, and as transportation fuels. By utilizing waste materials and sustainable resources, biomass fuels contribute to a more sustainable energy future while promoting environmental conservation.
