The similar thing I have heard Elon Musk saying in some interview that it's just a myth that people have to think we will never able to generate enough energy out of solar-panels compared to the nuclear reactors. He said that the amount of land one needs to build a massive nuclear plant and then other things to maintain it and considering the 10-50 miles area enveloped to plant where it is dangerous to live. If you use the same amount of land to place solar-panels then the energy produced by solar will overtake that of from nuclear plants.
