   You can get better cooling performance at the cost of slight water usage or you can use more energy without using water at all.

   The greener solution is to use water.

      This is entirely dependent on where you are geographically in terms of rainfall and weather. Both water and energy are abundant. The trick is getting them where you need them. So the where is what matters.
