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 as of January 1, 2016, there were about 2,462 trillion cubic feet (Tcf) of technically recoverable resources of dry natural gas in the United States. At the rate of U.S. natural gas consumption in 2016 of about 27.5 Tcf per year, the United States has enough natural gas to last about 90 years. The actual number of years will depend on the amount of natural gas consumed each year, natural gas imports and exports, and additions to natural gas reserves.

Technically recoverable reserves include 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 of crude oil and natural gas are additional volumes estimated to be technically recoverable without consideration of economics or operating conditions, based on the application of current technology.
