Tark Energia

We install server modules to houses as additional heat sources.


The global need for variable cloud services grows every day. As a result all data centers in the world combined now consume more electricity than Japan. About 90% of that energy goes to waste in form of heat into the atmosphere.
Instead of building new infrastructure for server hosting, we offer a solution that makes more sense economically and environmentally. Tark Energia installs servers modules into existing apartment building heating systems, where the computers are cooled cheaply and the heat is utilized.
