The oil policy that Obama’s Administration has been pursuing since 2014 is characterized by its great efforts to balance among increasing domestic oil supply，protecting environment and reducing carbon emission. On one hand，the Administration for the first time proposed opening to offshore oil drilling in the U.S. Atlantic outer continental shelf since the 1980s，as well as parts of the Arctic in Alaska. On the other hand，it barred energy development in most parts of the Arctic National Wildlife Refuge by declaring the land as “wilderness”. The Administration also insists to “green” the U.S. fossil fuel industry through issuing new regulations on the oil and natural gas production. Domestic oil production surge has brought about an impact on the crude oil export ban in the U.S. The Department of Commerce already began approving the exports of certain types of ultra-light crude oil. The U.S. federal government still maintains a large amount of fossil fuel subsidy and it is not expected being cancelled soon.
