As an alternative to oil, shale gas has modified today's economic and global political scenario, providing Washington with new capabilities for redesigning its national and foreign energy policies toward innovative, self-sufficient development. The U.S. economy is highly dependent on energy resources; however, in the last decade, the shale revolution has aided the country in gaining relative economic stability in a volatile global economy. Shale gas has encouraged economic development in the North American region, while raising important environmental concerns about the extraction process called hydraulic fracturing or "fracking".]]></p></abstract>
