"Electric vehicles, you might have heard, have a mineral problem.
Beneath the floor of an EV sits a 900-pound battery filled with minerals
extracted from around the world. Millions of tons of lithium, cobalt, bauxite
and other minerals are mined, processed, shipped and refined — sometimes
leaving a trail of human rights and environmental abuses.
For some, that makes fossil fuel engines look good by comparison. No one wants
to drive around on the cobalt equivalent of blood diamonds. But does all this
mining negate the climate and environmental benefits of EVs compared to
sticking with gas?
I looked into the world’s evolving supply chains for the clean-energy economy.
In every scenario, it turns out, the demand for battery minerals represents a
tiny fraction of the amounts of fossil fuels now needed to power the world.
But not everything is measured in tons. For EVs to fulfill their clean-energy
promise, they need to avoid repeating the mistakes of the first Industrial
Revolution. Miners and manufacturers can embrace cleaner ways to get the
materials they need, and recover more of what they use.
Here’s how EVs and gasoline cars stack up."
