European Data Centers Reuse Waste Heat to Heat Homes
European data centers are increasingly repurposing waste heat to support local heating systems. Major companies like Google and Microsoft are leading initiatives that could significantly reduce energy costs for nearby homes and businesses. This trend aligns with broader sustainability efforts in the tech industry to minimize environmental impacts.
- ▪Google's Hamina data center will supply 80% of the annual heat demand for a local district in Finland.
- ▪Microsoft's Høje-Taastrup data center in Denmark is expected to produce enough surplus heat to warm about 6,000 homes.
- ▪Amazon Web Services' facility in Dublin provides 92% of the heating demand for a nearby technological campus.
