Since the shale revolution about ten years ago, empowered by hydraulic fracturing (fracking), Pennsylvania's output of natural gas has soared to 32 times what it was before and 20% of all U.S. gas.
Benefits abound. With a tremendous local supply of this low cost energy source, Pennsylvanians are using less coal and more gas. That accounts for lower power sector CO2 emissions. Pipelines are being built to ship the gas to other states.
And there's more. Nationally, the U.S. now produces more energy than it consumes whereas we used to be dependent on imports from both friendly and unfriendly countries. Innovation has led the way.
"Better technology and techniques [i.e. innovation] conjure the deep magic of any successful modern economy."
