Natural Gas is a fossil fuel found in a gaseous state and is often found close to deposits of oil. Natural gas can be important because we can use it for cooking, heat, electricity, and some other things.About one-fifth of the world's natural gas comes from offshore drilling. When natural gas was first discovered, no one had a use for it. It was burned off as a waste product. Now natural gas is used to produce heat and light. It is much cleaner to burn than oil because it does not contain sulfur.
