What role does liquefied natural gas (LNG) play as an energy source for the United States?
On an annual basis over the past five years, the United States imported between 13% and 16% of its natural gas requirements. Most of these imports were in gaseous form delivered by pipeline from Canada. However, natural gas imports have also come in liquid form from overseas. Between 1% and 3% of U.S. demand for natural gas was met by LNG in the past five years.
