U.S. set for fracking bonanza, says historian Ferguson

Outright recession or sub-standard growth, stubbornly high unemployment and fiscal crises have been the topics du jour when it comes to the world's biggest economy.

But now an unlikely champion for U.S. growth under the Obama administration has emerged -- a former adviser to a Republican Party presidential candidate and Harvard history professor, Niall Ferguson, who says America could actually be heading toward a new economic "golden age."

And it has nothing to do with Washington and everything to do with energy.

Ferguson, who is also an author and commentator, believes the production of natural gas and oil from shale formations via a process known as "fracking" -- forcing open rocks by injecting fluid into cracks -- will be a game changer.
