The U.S. Energy Information Administration estimates that the natural gas reserves of the United States will last around 92 years. The estimate will hold true only if the national natural gas consumption rate stays at the 2011 levels, around 24 trillion cubic feet per year.
The United States' natural gas reserves consist of around 2,203 trillion cubic feet of technically recoverable natural gas. Technically recoverable energy reserves refer to those that are retrievable using contemporary technology, as well as those whose production is already expected given already existing economic conditions. The estimate for how long natural gas reserves in the United States will last is based on both the expected production and any other available energy.
