Energy DemandEnergy Supply at Its Limits: Balancing the Expansion of Digital Infrastructure with Renewable EnergyLéa Wilson, Chanelle Pfenninger, and Adele Galli
Where is the limit for the growing energy demand of data centres in Switzerland? Over the last seven years, the amount of energy demand caused by data centres has increased from 3.6 to 7.6 %, meaning that their energy consumption has more than doubled. Despite this rapid growth, energy providers such as EKZ are obligated to connect new customers to the grid, regardless of the building type or its energy demand. Now is the time to set limits.
This work proposes a limit in which data centres may not exceed 20 % of Switzerland’s total electricity demand. Furthermore, large-scale Big Tech data centres should no longer be replaced or newly constructed after the end of their operational lifetime. Instead, they should gradually be replaced by intermunicipal data centres, where municipalities produce the required electricity locally through renewable energy sources.
