In the US the majority of natural gas comes from "tight gas" which is produced by fracking. It can also be produced as a by-product of crude oil extraction (the alternative is flaring it off) or from biogas (capturing methane from trash), but both of those accounts for very little production [0]. There are industrial processes that need natural gas as part of the chemical reaction, so there will always be a market for it. Using natural gas for electricity or heating is definitely not "green" or renewable.
