In this video, CNN looks at an underground datacenter built by Helsingen Energia and ISP Academica in Helsinki. Located 30 meters below a historic church, the 2 megawatt facility is cooled by sea water and its waste heat is used to heat residential buildings.

Eco-efficient computer halls could really save significant amounts of primary energy and at the same time recover wasted heat for recycling,” said Sipila. “It is perfectly feasible that a quite considerable proportion of the heating in the capital city could be produced from thermal energy generated by computer halls. When it’s cold outside, you need a lot of heat to warm the house. But the data centers were putting all of this heat into the atmosphere.”

At tip of the hat goes to Data Center Knowledge for pointing us to this story.
