Natural gas drilling in Pennsylvania in 2010: In July, Germany put the brakes on plans to use hydraulic fracturing, commonly known as fracking, to extract natural gas in places where it is difficult to access, such as shale or coal beds. The technique injects water laced with chemicals and sand to release natural gas. Many worry the chemicals could contaminate groundwater.
