Answer:
Methane is a chemical compound with the chemical formula CH4, symbolizing one atom of carbon and four atoms of hydrogen. It is a group 14 hydride and the simplest alkaline, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Methane naturally occurs both below ground and under the seafloor, and is formed by both geological and biological processes. In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water. Methane is important because it can be captured from landfills, can be burned to produce electricity, heat buildings, or power garbage trucks. Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs. In fact, Jordan Dairy Farms in Massachusetts uses a biodigester to turn cow manure into methane gas, which is used for fuel or turned into electricity.
