Biogenic gas is created by mathanogenic organisms found in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is created from buried organic material.

3. Used for gasoline by compressing natural gas less than 1% of its volume and standard pressure. Natural gas powers more than 12 million vehicles. NATURAL GAS What is it used for??Example how its used.
