Is ecological damage worth the benefits of creating a geothermal energy plant? Yellowstone • Potential impacts on groundwater • Metal-rich geothermal waters could: • leach into soil and vegetation • enter food chain of mammals • Adverse impacts on hydrology and geothermal dynamics of hot springs, pools, and geysers • Integrity of geysers can be compromised over time http://www.edupics.com/geyser-eruption-yellowstone-national-park-t8756.jpg
Is the solution of reinjection of water into geothermal systems worth inducing seismic activity? • Reinjecting water lubricates fault lines, releasing tectonic stress • E.g. Yellowstone has a history of major volcanic events • However • Decreases depletion of geothermal fluids and pressure • Favours gradual release of tectonic stress • May prevent ground subsidence http://images.forbes.com/media/2008/08/19/geothermal_diagram_426x274.jpg
