聊起能源，大家总先想到石油、煤炭、风电光伏，却很少有人留意脚下地壳深处的地热能宝库！ 它不像化石能源会被耗尽，也不像风光电靠天吃饭，稳定又可持续。 有数据测算，中国地下可开发的地热资源，相当于全球煤炭储量的四亿倍，这规模简直吓人！ 网友表示：这简直就是天佑我国！ 近几年咱们在深层地热井钻探、干热岩发电技术上接连突破，雄安新区等示范区也落地见效，让地热能从边缘走向能源舞台中央。 这座沉默的地下宝库，会不会彻底改写中国未来的能源格局？ 换句话说，每一份地热能都是地球漫长历史的沉淀，它的总量巨大，稳定性远超传统能源。 根据现有科学测算，中国地下可开发的干热岩资源，换算成石油当量，大约等于二十万个大庆油田的储量。 如果将视角拉到整个地壳层面，地热能储量大约是全球煤炭储量的四亿倍，这意味着中国脚下的地下能量足够支撑上百年甚至更长时间的能源需求。 更重要的是，地热与煤炭、石油等一次性消耗能源不同，它属于典型的可持续能源，只要开发方式合理，就能长期稳定输出。 这一特性对能源安全和应对全球减排压力的中国而言，有着无可替代的战略意义。 过去地热能未能成为主流，并不是它不重要，而是技术条件限制了它的发展。 浅层地热资源分布有限， ...
