The problem with cooling…
…is that any kind has environmental impact. 
Heating the outside air causes the least problems, but is also least efficient. 
Heating the water is exceptionally efficient (because it starts out colder!), but destroys ecosystems.
(Google put their new datacenter on a river, only to face controversy for heating the water.)
