This makes it seem like you think all energy consumption leads to water boiling? At the peak of a sunny day in the american southwest, a random square mile receives over 2000 megawatts of power from the sun. In a 24-hour period that same square receives ~16 gigawatt-hours of solar energy. It doesn't all get used to boil water. And as others have said, with a closed loop cooling system, no water is evaporated that isn't also re-condensed.

My 1500W space heater could boil 4.32 gallons of water every hour. But it isn't.
