The energy transition requires a lot of minerals. Lithium, copper, cobalt, nickel, and other materials that are collectively known as “critical minerals” are vital components of most clean energy technologies. According to the International Energy Agency, getting on track for net zero will mean a sixfold increase in the demand for these materials by 2040. But mineral production has a mixed history. Without proper protections, mining can have negative impacts on environmental health, labor practices, and Indigenous communities. Therefore, the prospects for a just energy transition will depend both on meeting future demand for critical minerals, and on doing so in a just and sustainable way.  What does the next decade hold for the mining industry? What challenges will critical minerals pose for energy and geopolitics? And what can be done today to overcome these challenges? This week, host Jason Bordoff talks with Ernest Scheyder about critical mineral supply. Ernest is a senior correspondent for Reuters covering the green energy transition and critical minerals. He is also the author of the forthcoming book, The War Below: Lithium, Copper, and the Global Battle to Power Our Lives. The War Below details the complex choices facing our world as the energy transition accelerates. Ernie has previously covered the American shale oil revolution, politics, and the environment
