BLACKPOOL, ENGLAND - JANUARY 17: The drilling rig of Cuadrilla Resources explores the Bowland shale for gas, four miles from Blackpool on January 17, 2011 in Blackpool, England. The rig is the first in the UK boring exploration holes 4000 feet deep to see if it is economically viable to extract the reported substantial natural gas from the shale deposits beneath the Lancashire coast line. In the United States, up to 45% of its gas market comes from shale gas. (Photo by Christopher Furlong/Getty Images) less
