What role does liquefied natural gas (LNG) play as an energy source for the United States?
On an annual basis from 2003 to 2008, 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 from 2003 to 2008.
