Oil rigs off the coast of Long Beach, Calif.: The Obama administration has approved more than 400 drilling permits since the BP oil spill nearly two years ago.

hen BP's explosion-wrecked Deepwater Horizon oil rig was bleeding millions of gallons of oil into the Gulf of Mexico from April to August of 2010, an overwhelming number of critics questioned the safety of deepwater oil drilling. Those days seem to be long gone. It's been more than a year since the Obama administration ended its post-spill moratorium on deepwater Gulf wells, and today, deepwater drilling is expanding in the waters off Mexico and Cuba, in the Mediterranean, and off the coast of East Africa. "We need the oil," Rice University energy expert Amy Myers Jaffe tells The New York Times. "The industry will have to improve and regulators will have to adjust, but the public will have to deal with the risk of drilling in deep waters or get out of their cars." Here, a numerical look at the resurgence of deepwater drilling:
