    Desalinizing water in order to use it to cool the power plants that provide the energy that is sued to run the desalinzation plant that is used to produce the water that is used to cool the power plants that are used to provide the ... well, you see there is no way to finish this senatnce.

    Just as there is no way to do what you suggest.  It would take 10 NEW power plants to power the desalinzation plant used to cool one old power plant. Then where do you get the water for those 10 new power plants?

    Once your out of fresh water, your out of the water cooling game.

      ...power plants. Sorry if I constructed that comment to imply that.

      The fact is we have water shortages in part due to energy facilities having "first dibs" on available fresh water. Residential and light commercial use of water is what I'm after here, and that is by some measures less than 20% of all current water use. One of the benefits of moving as rapidly as possible to wind and solar is the reduction of stress on existing stocks of fresh water.

        Cracking water is very power-intensive. If you build a de-salinization plant, it probably would need the equivalent of a coal-burning plant dedicated to powering the desalinization plant.  Which in turn is going to consume more surface water.

        Sure, if all power came from wind and solar, then powering the desalinization plant would not consume much surface water. But OTOH if all the coal plants were shut down, their drain on the water would be gone.  And that might remove the need for the desalinization plant.

        Trouble is, there is not nearly enough solar and wind to do this and there might never be.  If humans had a controllable fusion process, there would be plenty of energy. But that's even further away.
