In 2008, Preesident Bush lifted an executive moratorium on offshore energy exploration along the Atlantic and Pacific coasts. And Congress allowed the legislative moratorium to expire. But as a move to explore for oil and natural gas moves forward, President Obama is apparently planning to reverse that policy. Why? What exactly is permissible right now? How much of an impact would offshore exploration have on energy supply and pricing? And what would be the enviornmental impact if this exploration were allowed to proceed? We ask Dan Kish, senior vice president of policy at the Institute for Energy Research.
