⚡️AI servers are heating Finnish homes
Finland is turning data center waste heat into urban infrastructure.
• AI-powered data centers generate huge amounts of heat during server cooling.
• Instead of dumping it, the heated water is fed directly into city district heating networks, then circulated back to the data centers.
Who’s already doing it
• Google (Hamina): heats ~2,000 homes for free, covering up to 80% of the city’s heating demand.
• Microsoft (Espoo): supplies heat to up to 40% of the city around 100,000 homes.
Data centers shift from energy hogs to critical utilities, lowering em
