The Washington Post has an interesting article on the potential for European companies to move operations to the United States due to the competitive cost of natural gas:  "German chemicals giant BASF, which operates the plant here, has announced plans for wide-ranging expansion in the United States, where natural gas prices have fallen to a quarter of those in Europe, largely because of American innovations in unlocking shale gas. *** Among those most affected are energy-intensive industries such as steel and chemicals, because they use natural gas as a raw material and power source. With Europe lagging in energy production, manufacturers on the continent warn that a chain reaction could shift more and more investment to U.S. shores."
