地热能利用（utilization of the geothermal energy）是指利用地下热能为人类服务。地热能和矿物燃料的区别在于不用燃烧。
但是这个进步取决于利用自然蒸汽以外的途径采集地热能。
But that progress depends on new technology that can move geothermal beyond naturally occurring steam deposits.
但是，为了利用地热能，你并不需要火山喷发。
But you don't need volcanic eruptions to make use of geothermal energy.
现在，地热能源主要在有非常活跃的火山表面的国家被利用，比如冰岛，这个国家四分之一的电力来自地热源。
Right now geothermal energy is mostly used in countries with unusually active volcanic surfaces, like Iceland, where more than a quarter of the country's electricity comes from geothermal sources.
