Biomass refers to organic materials that come from plants and animals. This includes things like wood, crop waste, and even animal manure. When these materials are used for energy, they can be burned directly or converted into biofuels, such as ethanol or biodiesel. Biomass is considered a renewable energy source because it can be replenished over time through natural processes. Using biomass for energy can help reduce reliance on fossil fuels and lower greenhouse gas emissions. However, it’s important to manage biomass resources sustainably to avoid negative impacts on ecosystems and food supplies. By harnessing biomass, we can create a cleaner and more sustainable energy future.
