 We think that a move to renewable energy should reduce the amount of mining on this planet by something like an order of magnitude. And the reason, if you think about it, it's clear. If you go mine some lithium and you stick it in a battery, then it sits there doing its work for the next 25 years, and then you can hopefully recycle it. If you go mine some coal, you set it on fire, and that means you have to go mine some more coal the next day.
