The natural gas market has been transformed by the rapid expansion of shale gas production. A dozen years ago, shale gas amounted to only about 2 percent of United States production. Today, it is 37 percent and rising. Natural gas is in such ample supply that its price has tanked. This unanticipated abundance has ignited a new political argument about liquefied natural gas — not about how much the United States will import but rather how much it should export.
The oil story is also being rewritten. Net petroleum imports have fallen from 60 percent of total consumption in 2005 to 42 percent today. Part of the reason is on the demand side. The improving gasoline efficiency of cars will eventually reduce oil demand by at least a couple of million barrels per day. The other part is the supply side — the turnaround in United States oil production, which has risen 25 percent since 2008. It could increase by 600,000 barrels per day this year. The biggest part of the increase is coming from what has become the “new thing” in energy — tight oil. That is the term for oil produced from tight rock formations with the same technology used to produce shale gas.
