In addition, geothermal heat from deep within the earth may warm the hidden lake.

此外，来自地球深处的地热也可能会让这个隐藏的湖变暖。

Geothermal heat pumps pipe water or antifreeze liquid through this layer of earth to siphon its energy.

地热热泵将管道水或防冻液泵过这层地球以虹吸其能量。

They're using geothermal heat to power it, and they're putting the CO2 into the Icelandic basaltic rock.

他们使用地热为其提供动力，并将二氧化碳注入冰岛的玄武岩中。

Since geothermal heat pumps rely on the consistent heat found in shallow earth, they can be implemented almost anywhere.

由于地源热泵依赖于浅层土壤中持续存在的热量，因此几乎可以在任何地方实施。

In fact, geothermal heat pumps are both cheaper to operate and at least two times more energy efficient than fossil fuel equivalents.

事实上，地源热泵的运行成本更低，而且能效至少是化石燃料同类产品的两倍。

However, generated from natural resources-such as sunlight, wind, rain, tides and geothermal heat, renewable energy is continuously being replenished by nature on a time scale appropriate to human use.

但是，像太阳光、风、雨、潮汐或是地热等可再生的自然资源正在源源不断地得到补充，从时间上说，这很适宜人类的使用。
