We are awash in natural gas so long as shale oil continues as a thing. Thats dependent on the price of oil staying above at least $60BBL If shale oil production goes down, so does Nat gas, although we currently have a huge surplus and still flare lots, so it might take a while.
Shipped LNG is 10% of US gas production. I wonder if a long East Coast port strike will put that gas back on the domestic market? The commodity is priced around the margins.
