但要将地热资源大加利用，通常就是简单地利用下面的热岩建立自己的贮藏库。
But the big play in geothermal energy has always been to simply use the hot rocks down there and create your own reservoir.
而加强型地热系统——也叫做EGS或“干热岩地热系统”——是一种能够在各种地区大规模加以应用的新方法。
Enhanced geothermal systems - also known as EGS or "hot dry rock geothermal" - are a newer approach that could be exploited in a larger number of locations.
地热发电厂利用火山地区——或者地温高且干燥的地点——的干热岩体传导热能给含水层畜热，然后将水注入含水层利用热岩体对其加热并使之汽化。
Geothermal power stations tap aquifers heated by contact with hot rocks in volcanic regions-or, in hot but dry spots, they pump water past such rocks to heat it up.
