U.S. coal power plants have killed (i.e. caused premature deaths of) 460,000 people over 20 years, according to the Guardian. That is not going to include future premature deaths due to climate damage. Sure, even switching to natural gas is much better than this, but I can’t help comparing it to nuclear power. Deaths and risks due to nuclear power have been much exaggerated, in my view. I can imagine a world where nuclear power was implemented on a much larger scale, along with electric vehicles and electric HVAC in buildings, decades ago. It could have been the bridge fuel that got us to a more renewable future. Or maybe we would have even learned enough by doing to decide it was a good choice for the long haul. So the question now is whether to double down on nuclear research and implementation, or just throw all our eggs in other renewable baskets.

And as for air pollution, there are just so many reasons to make it a central issue, from the obvious health impacts of breathing particulate matter to the multiple benefits of spending more time outdoors getting around under our own muscle power in clean air. It could be a virtuous loop if we really made it a priority.
