About this episode
Cobalt is the most important mineral of the future. It’s a key part of lithium-ion batteries, which power cell phones and laptops, not to mention electric cars. That demand is giving rise to a mining industry in Idaho, which sits atop a giant cobalt deposit. But the environmental costs of extraction raise questions about what “clean energy” really means. Guest: Michael Holtz , freelance journalist and author of “Idaho Is Sitting on One of the Most Important Elements on Earth.” If you enjoy this show, please consider signing up for Slate Plus.
