The Marcellus Shale could potentially be the next big source for energy production for Pennsylvania. This state has been known for its rich endowment of fossil fuels, with substantial reserves of coal and now it has the potential to be known for natural gas from the Marcellus Shale.

Found in the Allegheny Plateau, the Marcellus Shale is a geological formation that holds a vast amount of natural gas. The natural gas found in the Marcellus Shale can only be accessed by hydraulic fracturing. Those who support the fracturing of the shale say that the amount of natural gas located in the shale can help the United States reduce its dependence on foreign gas; bring jobs and revenue to rural areas. It is estimated the Marcellus Shale contains between 50 trillion to 500 trillion cubic feet of natural gas. The greatest argument for hydraulic fracturing is that it will bring substantial economic development for the Pennsylvania section of the Marcellus Shale. The extraction of natural gas in Pennsylvania is contended that it will bring much-needed revenues to the state, jobs to the community and revenues from leasing to struggling landowners.
