There's been a big rally in natural gas stocks including Southwest Energy (SWN) - Get Report , Range Resources (RRC) - Get Report and Cabot Oil & Gas (CBT) - Get Report this year, but the momentum may not be finished yet. 

The U.S. has a ton of natural gas, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Stop Trading" segment. This country has the lowest cost of production aside from Kuwait.

As companies continue to build out natural gas infrastructure and pipelines, it will create tens of thousands of jobs, he noted, as will exporting the gas. 

"We are blessed with large deposits of natural gas" throughout the country that is cleaner than coal, Cramer said. So this coming year could be big for the commodity. "It is the bright light of 2017," Cramer concluded.
