Does geothermal energy production create the same environmental dangers as natural gas fracking?

    “One of the biggest fears involving geothermal energy – especially the Enhanced Geothermal System – is the possibility of some seismic activity from drilling holes in the rocks and pumping in highly-pressurized water. In Basel, Switzerland a geothermal plant had to be shut down after an earthquake of magnitude 3.4 with 60 aftershocks shook the town.”

    This is quite different from the concerns that natural gas fracking pose. 

    fracking, involves injecting water, sand, and a cocktail of chemicals at high pressure into rock formations thousands of feet below the surface. Fracking involves relatively new technology, and is not without risks. This month alone, there have been two major accidents in the Pennsylvania-West Virginia region involving hydraulic fracturing, one of which involved a well explosion.

    The major concern with such drilling is the chemicals used in the process. Because the federal Energy Policy Act of 2005 exempted hydraulic fracturing from regulation under the Safe Drinking Water Act, shale gas drillers don’t have to disclose what chemicals they use. According to the Environmental Working Group, fracking has already been linked to drinking water contamination and property damage in Colorado, Ohio, Pennsylvania and Wyoming.”
