Ove zemlje imaju besplatno grejanje: A koriste nešto što može i u Srbiji
Toplota iz servera postaje stabilan izvor grejanja u Nordijskim zemljama, podaci iz Finske i vedske pokazuju globalni energetski zaokret
TL;DR
- Data center heat is being repurposed for district heating in Nordic countries.
- Finland is a leader, using waste heat to warm tens of thousands of homes, including those in underground shelters.
- This model is seen as a prime example of a circular energy economy.
- In Helsinki and Espoo, excess heat is captured, transported via insulated pipelines, and integrated into the city's district heating system.
- Companies like Helen in Finland and Stockholm Exergi in Sweden are collaborating with data center operators for heat recovery.
- Stockholm has over 30 data centers connected to its district heating network, supplying heat to tens of thousands of apartments.
- A single data center in Espoo already heats about 40,000 households, with a new Microsoft cluster potentially heating up to 100,000 homes.
- Google's data center in Hamina aims to supply up to 80% of the local community's heating needs.
- These projects significantly reduce carbon dioxide emissions by replacing fossil fuel-based heating.
- Recycled heat from servers could eventually meet about 10% of Helsinki's total heating demands.
