It took nearly two decades for Texas oil man George Mitchell to develop fracking for natural gas. Now his process has unlocked an energy bonanza for the U.S.
Every fracking well requires miles of pipe. The result is new investment in Ohio steel mills -- which also benefit from cheap natural gas for fuel.
The presidential campaign talks a lot about coal in Ohio, but the fossil fuel of the moment is oil. Fracking has made possible a second oil boom, more than a century after the state's first one.
Pennsylvania's state colleges have been hit hard by budget cuts. Now the state is allowing natural-gas drilling on campuses to raise money for the system.
