If you use an evaporative cooler, then the temperature of the air you're blowing out of a building is lower than the temperataure of the air your drawing in, and the heat content differs by the heat of evaporation.It is not just the power consumption. AC's don;t magically create cold. They simply move heat from inside to outside, creating even more heat while they do it. The prevalence of AC and the lack of vegetation are why cities are becoming little heat islands in the summer.
