Summary
In Finland, the heat generated by data centers (long considered mere energy waste) is now being harnessed to heat thousands of homes. Thanks to efficient heat pumps and well-developed district heating networks, this "waste heat" is recovered, reused, and fed into municipal systems. The country thus exemplifies a circular economy model applied to the digital sector.
Finland's success rests on three key factors:
A cold climate, generating a high demand for heating; a dense urban heating network (up to 50% of homes connected, compared to around 5% in France); largely decarbonized electricity production.
Data centers are thus integrated into a coherent territorial energy system. In some cases, heat is supplied almost free of charge to local operators, allowing households to reduce their bills by 10 to 15%.
