A group of Yale students which is being led by Yale Professor Emeritus Paul W. MacAvoy who are curious about the quantity has a good benefit on the Unite States economy. They have performed a cost-benefit and finding the Pros and Cons they called it "The Arithmetic of Shale of Gas".
In 2008, before the shale boom really took off, the nominal price of natural gas (that is, the price at the Henry Hub in Louisiana) averaged $7.97 per mcf. In 2011, the price averaged $3.95 per mcf. Multiply that price drop of $4.02 per mcf by the 25.6 trillion cubic feet the country consumed in 2008 and you find that, thanks to the shale boom, America is paying $103 billion a year less for natural gas. Natural gas prices are falling even further since 2011, increasing the potential benefits.
