See, that dystopian future just won't happen. We're not going to just wake up one day and find that there's no coal left in the ground, and whoopsie, we can't power the world anymore! It's an asymptote, not a brick wall. Coal reserves are going to disappear slowly, and new coal will be harder to find and more expensive to mine. So the price of coal will rise, gradually. And just as gradually, people will start getting power from sources that used to be more expensive than coal, but aren't anymore since the price of coal went up. We're watching that happen right now: coal prices are going up and natural gas prices are going down, and the big players are shifting from one to the other.

We'll all end up on renewable tech eventually, as fossil fuels become more expensive through dwindling supply. The point is that we should work so that "eventually" becomes "soon", for reasons of pollution and climate change. It's not because we're going to run out.
