Answer:1. Renewable Energy Source
2. Reduced Greenhouse Gas Emissions
Step-by-step explanation:
1. Biogas is considered a renewable energy source because it's generated from organic waste materials like agricultural residues, animal manure, and sewage. With the continuous biogas production can be sustained over time, reducing reliance on finite fossil fuel resources.
2.When organic waste decays in landfills or other environments without oxygen, it releases methane, a potent greenhouse gas. However, by capturing and utilizing biogas, methane emissions are significantly reduced. Biogas facilities not only produce a useful energy source but also help prevent the release of methane into the atmosphere, contributing to efforts to combat climate change. It also has an advantage in mitigating greenhouse gas emissions.
