The giant Oklahoma natural gas company and its charismatic CEO Aubrey McClendon face an uncertain future.

Billionaire investor T. Boone Pickens explains why he recently left natural gas producer Chesapeake Energy, and what he thinks of a federal energy policy in the United States.

The nation's second largest natural gas company, Chesapeake Energy, has seen its stock plummet almost 40 percent this year. And this week it's been borrowing billions of dollars at high interest rates just to make ends meet.

Natural gas is housed in underground salt caverns, depleted oil fields and aquifers. And the glut of gas means they are filling up too fast.
