Some extra relevant information:
Renewable energy derived from burning organic materials such as wood and alcohol is commonly known as bioenergy. Bioenergy is a sustainable energy source that utilizes biomass to generate heat, electricity, and even biofuels. Biomass, which refers to any organic matter produced from crops, forests, or waste, is converted into energy through various processes like combustion, gasification, and fermentation. These processes release the stored energy in biomass, making it a viable and environmentally friendly alternative to fossil fuels. Bioenergy is a versatile and renewable solution that not only reduces greenhouse gas emissions but also contributes to waste management and rural development.
