Chesapeake CEO Aubrey McClendon is no stranger to controversy.

And his next big bet is largely controversial - he's convinced the future of his company as well as the nation lies with the nat gas in the Utica Shale.

If he's right, it could change – well, everything.

The Utica shale is a rock formation which stretches deep underground, across parts of New York, Pennsylvania, Ohio, and West Virginia. According to some estimates the Utica Shale may contain 38 trillion cubic feet of undiscovered gas.

Chesapeake Energy is the largest stakeholder in the Utica shale, with the company and its CEO Aubrey McClendon betting the proverbial farm that nat gas is about to become the nation's preferred source of energy.

Not only is nat gas abundant in the United States but it's also the cleanest burning of all the fossil fuels.
