You don’t need broken windows for economic growth from action against climate change. We’re going to see numerous core technologies of civilization becoming significantly cheaper than the incumbent technologies.

We’ve already seen that with LEDs and lighting. Likewise opportunistic electricity use (which doesn’t depend on time and location) derived from wind or solar is already perhaps half to a third of the cost of the cheapest fossil fuel source.

Electric vehicles will also end up significantly cheaper per mile, and in fact are already cheaper at the right levels of utilization.

Fossil fueled electricity and road transport are going to be progressively undercut by the zero carbon alternatives, and that’s going to make the global economy vastly more productive.

That’s to say nothing of the economic benefits of reducing air pollution and the massive costs associated with its impacts on human health.
