Known as the “vitamins of industry,” rare earths refer to a cluster of minerals widely used in green technologies such as wind turbines, rechargeable batteries, and electric vehicles. Rare earth elements embedded in these products keep them light, efficient, and affordable. They’re essential to the decarbonization of the global economy envisioned in the Paris Climate Agreement, agreed to by 192 countries in 2015. And we may soon face a significant shortage, due in no small part to changes in China.
