"Many countries can easily go 100% renewable"

Sorry but no. There are several major issues with that if you want your power to stay on all the time. Storage would be needed which even for the smallest countries on this list would require over a years worth of worldwide battery production. And grid stabilization would be almost impossible and that's just for starters. All 9 of these countries are mostly hydro. The renewables in this case are almost incidental. Also these dams were built decades ago for reasons that have nothing to do with the environment.
