使用“水力压裂法”来开采天然气究竟是清洁的还是会造成环境灾难,在美国有很大争议,相比之下,对地热这种相对来说不太起眼的能源的利用,尚未引起很多争议。新的“增强型地热系统”(EGS)似乎能激发地热更多潜力,但是它和页岩一样也存在隐忧。这个行业可能不喜欢这样的比较,但EGS就是地热压裂。数百万加仑的水和化学品在相对高的压力下注入到垂直井,冷水经 In the United States, there is much controversy over the use of “fracking” to clean natural gas or cause environmental catastrophe. By contrast, the relatively unobtrusive use of geothermal energy such as energy Cause a lot of controversy. The new Enhanced Geothermal System (EGS) seems to be able to excite more potential for geothermal energy, but it is just as hidden as shale. This industry may not like this comparison, but EGS is geothermal fracturing. Millions of gallons of water and chemicals are injected into vertical wells at relatively high pressures and chilled water passes through
