Well even if we take those nonsense extrapolations seriously and had the material capacities to build that infrastructure globally (remember it isn't a local problem), what is also lacking in many countries are skilled workers who actually put that stuff together. I can't seem to find enough political action to fulfill that part. And it's not only the production side, but the transport of the energy (grids and storage) and then also the consumer side. Those heat-pumps aren't gonna install themselves, you know.
