The planet is warming, dangerously so, and burning more coal will make it worse. President-elect Donald Trump thinks man-made climate change is a hoax and he's promised to revive the US coal industry by cutting regulation. So renewables are dead in the water, right? Maybe not.
President Trump can't tell producers which power generation technologies to buy. That decision will come down to cost in the end. Right now coal's losing that battle, while renewables are gaining.
