Its a thing that cannot be generalized. However, many datacenters use evaporative cooling. Especially when the DC is built in a region with relatively warm outside temperatures, it‘s basically the only viable way to get rid of all that heat.
It seems weird then that they are not locating data centers around northern rust belt areas where the industrial land use would not be an issue and rivers/lakes are plentiful (being the main reason those cities and industry developed there in the first place).
