Desalination is incredibly energy intensive. Based on average American water consumption, California would have to build another 10 gigawatts of electrical capacity to desalinate all their required water or some lesser amount depending on how much they needed. Desalination is as much as 3 to 10 times more energy intense than conventional fresh water treatment. There is no reliable green energy source that can do that outside of nukes and hydro electric. Either that or you're stuck with coal and natural gas or some combination of the above.
