We now have the technology to create a grid of cheap fully renewable electricity

The main solution to climate change is well known — stop burning fossil fuels. How to do this is more complicated, but as a scholar who does energy modeling, I and others see the outlines of a post-fossil-fuel future: We make electricity with renewable sources and electrify almost everything. There is debate, though, about whether fully renewable electricity systems are feasible and how quickly the transition can be made.
