In Toronto we have this huge system of underground cooling that transfers cool from the lake. It's great. https://en.wikipedia.org/wiki/Deep_water_source_cooli

  Double great because it only cools using water that the city was planning on using anyway. If they heated the water up and sent it back into Lake Ontario, the temperature differential would have a drastic impact on the wildlife in the area.

  Pretty cool! One thing to note is the cooling capacity is limited to the consumption rate of the city based on how it's designed right now. > The cold water drawn from Lake Ontario's deep layer in the Enwave system is not returned directly to the lake once it has been run through the heat exchange system. The Enwave system only uses water that is destined to meet the city's domestic water needs. Therefore, the Enwave system does not pollute the lake with a plume of waste heat.
