The issue with turbines is not their capital cost (which is on par with the still falling all-included cost of PV) but rather operating cost. Steam turbines need frequent, expensive overhauls because superheated steam under high pressure is very hard on everything inside. Renewables suffer no opex of such scale. They age out and need to be replaced, on a time scale of decades, but will be much cheaper to replace, then, than they cost up front. Probably perovskites will be used to replace silicon.
