In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into Earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy."</p><p>[...]</p><p>"Some geothermal plants also produce small amounts of <a href="https://kolektiva.social/tags/mercury" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mercury</span></a> emissions, which must be mitigated using mercury filter technology. Scrubbers can reduce air emissions, but they produce a watery <a href="https://kolektiva.social/tags/sludge" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sludge</span></a> composed of the captured materials, including <a href="https://kolektiva.social/tags/sulfur" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sulfur</span></a>, <a href="https://kolektiva.social/tags/vanadium" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vanadium</span></a>, <a href="https://kolektiva.social/tags/silica" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>silica</span></a> compounds, chlorides, <a href="https://kolektiva.social/tags/arsenic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>arsenic</span></a>, mercury, <a href="https://kolektiva.social/tags/nickel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nickel</span></a>, and other heavy metals.

Most geothermal facilities address this risk by re-injecting wastewater back into geothermal reservoirs after the water’s heat has been captured. </p><p>"Hydrothermal plants are sited on geological “hot spots," which tend to have higher levels of <a href="https://kolektiva.social/tags/earthquake" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>earthquake</span></a> risk. There is evidence that hydrothermal plants can lead to an even greater earthquake frequency. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes. In this process, water is pumped at high pressures to fracture underground hot rock reservoirs similar to technology used in natural gas hydraulic <a href="https://kolektiva.social/tags/fracturing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fracturing</span></a>. (See How Natural Gas Works for more information.) Earthquake risk associated with enhanced geothermal systems can be minimized by siting plants an appropriate distance away from major fault lines. When a geothermal system is sited near a heavily populated area, constant monitoring and transparent communication with local communities is also necessary."</p><p><a href="https://www.ucsusa.org/resources/environmental-impacts-geothermal-energy" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">ucsusa.org/resources/environme</span><span class="invisible">ntal-impacts-geothermal-energy</span></a> </p><p><a href="https://kolektiva.social/tags/Fracking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Fracking</span></a> <a href="https://kolektiva.social/tags/GeothermalEnergy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GeothermalEnergy</span></a> <a href="https://kolektiva.social/tags/ThinkBeforeDrilling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ThinkBeforeDrilling</span></a></p>
