PITTSBURGH, Nov. 14, 2013 /PRNewswire-USNewswire/ -- Today, Governor Tom Corbett addressed more than 3,000 attendees at this year's Developing Unconventionals East Conference in Pittsburgh which focused on the significant impact of the Marcellus and Utica gas plays on the Appalachian Region. Pennsylvania is currently second in the nation for natural gas production and fifth in the nation for overall energy production. "Our energy industry is creating tremendous economic and environmental progress for Pennsylvania's citizens," Corbett said during his address to the conference delegation. "Home heating costs have been cut in half; electricity prices are down 40 percent; and according to the EPA, carbon emissions are down by 7 percent.'' "More than 200,000 people are working in jobs created or made more prosperous and more secure by the vast wealth being tapped from our energy industry, including the Marcellus Shale gas play," Corbett said. "Just visit Williamsport, Green County, Washington County or any of a dozen others, and see the crowded restaurants, the full motels and the stores who are seeing heavier customer traffic and higher sales. Ask those people if they'd be doing this business without the drilling industry." The Pennsylvania Department of Labor & Industry (L&I) uses the Quarterly Census for Employment and Wages (QCEW) to measure employment levels and to track the employment change of the energy industry in the state. Employment data indicate that there are 28,155 jobs in the industries where core activities for Marcellus Shale occur, which is an increase of 162 percent since 2009. Work in these core industries is often the most high-profile and visible work related to Marcellus Shale. These industries include drilling and extraction work, building pipelines, and transporting natural gas through pipelines.
