I never said we can't do also wind, solar, thermal, and hydro; in fact we have to do all of them. But, hydro isn't possible in most places (and also makes "a part of the world uninhabitable" too — look at how much the Three Gorges Dam displaced, for example), nor is geothermal. And wind and solar are inconsistent — great as part of it, but they can't be the entirety of the grid, unless you want the entire country to go dark on a cloudy day, cuz we simply can't make batteries store that much.
