This completely ignores the need for baseload generation. Wind and solar will probably always be cheaper, but the power grid will likely always need a diverse array of power supplies. If your photovalic cell factories get bombed, how will you make more? If Egypt were 100% solar powered, it would be trivial to defeat them in a war by shooting less than a million dollars of artillery shells into their solar plants, leaving everyone in the dark in perpetuity. Japan was almost wholly dependent on the US for oil and coal before the US pulled their delivery contracts which was partly why they bombed pearl harbor, they had little to no power diversity. Nuclear and hydro will always backstop grid energy, even if solar becomes free or net negative.
