China has commenced construction on what is projected to be the world's largest hydroelectric dam, located in the remote region of Tibet. The $167 billion project, endorsed by President Xi Jinping, is intended not only to enhance China's energy capacity but also to stimulate economic growth. The scale of the dam is immense, with plans to use approximately 60 times the amount of cement used in the Hoover Dam, more steel than that in 116 Empire State Buildings, and a volume of concrete sufficient to surpass previous large-scale constructions. This mega-dam is expected to have significant implications for the regional energy landscape and geopolitical dynamics. However, there are concerns about potential environmental risks and the broader impact on neighboring countries. The project reflects a shift in the role of hydroelectric infrastructure, which historically aimed at uplifting developing nations, now intersecting with demands from emerging sectors such as cryptocurrency mining and data centers.
