英国最后一座燃煤发电厂——诺丁汉郡的索尔河畔拉特克利夫火电厂（Ratcliffe-on-Soar Power Station）——于10月关闭，标志着英国142年燃煤发电时代的终结。 英国逐步淘汰煤电在国际上意义重大。它是首个实现这一里程碑的主要经济体，也是首个G7成员国。1882年，英国在伦敦霍尔本高架桥（Holborn Viaduct）上建成了世界上第一座燃煤发电厂。 上微信关注《碳简报》 Carbon Brief的分析显示，从1882年到索尔河畔拉特克利夫火电厂关闭，英国的燃煤电厂共燃烧了46亿吨煤炭，排放了104亿吨二氧化碳（CO2），这比大多数国家从所有来源产生的CO2都多。 英国对煤电的逐步淘汰，将有助于推动煤炭总需求达到17世纪以来的最低水平。 逐步淘汰建立在四个关键要素之上：替代电源的可用性、结束新煤炭产能建设、定价外部因素，以及明确和长期的政府政策。 随着英国致力于到2030年实现电力行业的完全脱碳，其在努力为气候行动建立另一个成功范例方面，既面临挑战，又面临机遇。 英国何时开始使用煤电？ 长期以来，英国的资源禀赋就包括丰富的煤炭，但几个世纪以来煤炭的使用量一直很少。煤炭用于发电的时间要晚得多。 最早的蒸汽机从1700年左右开始使用。它通过燃煤将水从矿井中抽出，以便开采更深的煤矿。 这些蒸汽机的效率非常低，但詹姆斯·瓦特（James Watt）和乔治·史蒂文森（George Stevenson）等发明家对蒸汽机进行了改进，使煤的使用更加经济，也更广泛。 如下图所示，经历了上述过程，英国的煤炭使用量开始激增，为工业革命、大英帝国以及全球CO2排放量的激增提供了动力。 格拉斯哥大学（University of Glasgow）经济与社会史高级讲师、《煤炭之乡：战后苏格兰去工业化的意义和记忆》（Coal Country: The Meaning and Memory...
