Within the next five years, the United States may become a large exporter of natural gas for the first time in decades. Increased development of U.S. natural gas resources, particularly shale gas, along with low domestic prices in recent years and idle liquefied natural gas (LNG) infrastructure, have drive: change in the US. The United States has exported some amounts of natural gas for close to 100 years, but has generally imported more than it has exported. However, imports have been declining since 2005, while exports have been climbing. As the debates over the economy, energy independence, climate change, and energy security continue, Congress is beginning to face important questions regarding a potential increase in U.S. natural gas exports. This book examines the changes in the U.S. natural gas market and the prospects and implications of the United States becoming a significant net natural gas exporter.
