The IEA assembled a large body of data about a central, and until now largely ignored, aspect of the energy transition: It requires mining industries and infrastructure that don’t exist. Wind, solar and battery technologies are built from an array of “energy transition minerals,” or ETMs, that must be mined and processed. The IEA finds that with a global energy transition like the one President Biden envisions, demand for key minerals such as lithium, graphite, nickel and rare-earth metals would explode, rising by 4,200%, 2,500%, 1,900% and 700%, respectively, by 2040.
