If the 20th century was defined by oil, journalist and author Nicolas Niarchos bets that the 21st century will be defined by batteries. In his book, The Elements of Power: A Story of War, Technology and the Dirtiest Supply Chain on Earth, Niarchos unpacks the hidden costs behind the world’s battery boom. In this episode, he and Oz trace how the race for cobalt and other critical metals is reshaping global power—why China dominates refining and battery innovation, what the U.S. would actually have to build to compete, and whether trade deals can realistically “clean up” the system.
