Rare Earths 101: Digging Up the Facts, with Jordy Lee

Renewable energy will rely on rare earth mining: "When people talk about the material considerations of renewable technologies, they say we''re going to need 1,000 percent more rare earths or we''re going to need 400 percent more lithium for all the batteries that we have to make. These types of conversations are really valuable in that they
