Frequently Asked Questions

How much natural gas does the United States have and how long will it last?

The U.S. Energy Information Administration estimates that there are about 2,214 trillion cubic feet (Tcf) of natural gas that is technically recoverable in the United States.  At the rate of U.S. natural gas consumption in 2013 of 26 Tcf per year, the United States has enough natural gas to last about 85 years.

Technically recoverable reserves consist of proved reserves and unproved resources. Proved reserves of crude oil and natural gas are the estimated volumes expected to be produced, with reasonable certainty, under existing economic and operating conditions.  Unproved resources are additional volumes estimated to be technically recoverable without consideration of economics or operating conditions, based on the application of current technology.
