I wonder if another kind of costs of wind and solar (and hydro!) is included? In Germany, we have to spend billions to build additional transmission lines. Since wind/solar/hydro energy is a lot more unstable in its output, a lot more energy has to be moved around the country. Also it cannot be produced near the heavy consumers (e.g. hydro energy from the north sea to heavy industry the Ruhr area). The instability of output also leads to more activity for coal-fired power plants, because they can bridge short solar energy lows (nuclear plants are too slow).
I found that article encouraging that wind/solar/hydro energy might hit break even, but I am not convinced that we are already at that point.
Polluting nice landscape with windmills is another downside. Although that is probably not that big of a problem in the US, since you have a lot more uninhabited space there compared to Germany.

Yes, there are important questions to be addressed about dispatchability—the degree to which the power generator can be fired up at will, as needed—voltage regulation, service level guarantees, and the evolution of utility business models and regulatory environment, which I have written a series of articles about"
