If all goes as planned, solar, wind and other clean energy technologies will help us abandon carbon emissions for good. But many green power sources perform their best only when nature cooperates, so an important (and sometimes overlooked) component of the energy transition is the ability to store electricity for a rainy or calm day. Lithium is the ingredient of choice for electric vehicle batteries, solar panels and grid elements. As these innovations ramp up, lithium demand is expected to soar by 90% over the next two decades, driving a surge in production efforts. Some experts predict a deficit in the mineral by as soon as 2025.
