Solar requires water too, though: Those panels need to be cleaned regularly. This source suggests that parabolic solar plants use about one quarter the amount per acre as agriculture: https://www.seia.org/initiatives/water-use-management https://www.seia.org/initiatives/water-use-management Unfortunately, I don't see anything right away that discusses water use for photovoltaics. I guess that it's even lower, but I honestly have no idea. So yes, the transition does reduce water use, but doesn't eliminate it.
