The US energy revolution is gaining pace as the Obama administration approved wider exports of liquefied natural gas and international companies committed billions to new infrastructure projects. Advances in fracking have unlocked new US oil and gas supplies and increased the potential for the US to export energy. The Department of Energy approved the Freeport LNG project in Texas to export to non-trade agreement countries. Separately, Japanese and European companies pledged $6-7 billion to the proposed $10 billion Cameron LNG plant in Louisiana. The developments underscore how the US shale boom is positioning the country to be a major global energy supplier.
