One of the cornerstones of Pres. Biden’s infrastructure plan involves massive expansions of the availability of charging stations for electric vehicles. I understand why: our automobile emissions account for approximately 25% of our greenhouse gases. Reducing those will have a quick, beneficial, and verifiable impact on the environment.
Unfortunately, mining the lithium needed to make batteries for our new electric vehicles has terrible impacts, too: ground water close to mines could be contaminated for more than 300 years. There are responsible ways to mine lithium, but they can’t keep up with the needs that we have for the material if we’re going to quadruple the number of electric vehicles on American roads in ten years.
So: what should we do?
