Green gas refers to a type of fuel that is produced from renewable sources, such as biomass or biogas. It is considered environmentally friendly because it can help reduce greenhouse gas emissions compared to traditional fossil fuels. Green gas can be used for heating, electricity generation, and as a vehicle fuel. One common form of green gas is methane, which can be captured from organic waste in landfills or produced through the digestion of animal manure. By utilizing green gas, communities can promote sustainability and decrease reliance on non-renewable energy sources, contributing to a cleaner environment.
