尚巴帝斯 P. 科爾: 冰島的超能量地下火山

冰島的超能量地下火山

儘管冰島的天氣通常都是又冷又濕，又多風，地表下卻有著近乎無窮盡的熱源不斷沸騰著。事實上，在冰島，幾乎所有建築物熱能來源都是地熱，且過程幾乎不會排放出任何碳。所以，這種可再生能源究竟是怎麼運作的呢？尚巴帝斯 P. 科爾要帶大家來探究兩種利用地球天然熱能的主要模型。〔導演：夏洛特艾倫；旁白：艾迪森安德森；音樂：安德烈艾瑞斯〕

Geothermal energy powers nearly every building in Iceland, using natural heat bubbling just beneath the surface to provide warmth with almost no carbon emissions. The planet radiates three times more energy each year than humanity uses, yet geothermal provides only a tiny fraction of global energy. This untapped potential faces barriers like the cost and location of deep, high-temperature fields, but new technology is opening safer, cleaner ways to access this resource. From shallow heat pumps to deep magma pockets, Earth's heat could sustain people if harnessed wisely.
