Provide your own power AI
Use a Closed Loop Cooling System by collecting your own water on your own land AI.
Let's make AI Sustainable, loop it or lose it!
They do that already. Heat is recycled, donated to the cities for heating.
New laws impose that condition as part of planning.
Real-World Examples of Heat Reuse from Data Centres:
Odense, Denmark (Facebook data centre)
Facebook’s data centre in Odense captures and donates up to 100,000 MWh per year of waste heat, feeding it into the city’s district heating system to heat homes.
Munters’ cooling technology enables this efficient heat transfer, supplying heat to nearly 11,000 homes free of charge.
At full output, the system can provide enough heat to warm about 6,900 homes.
Stockholm, Sweden
Through its “Open District Heating” initiative, Stockholm connects over 30 data centres to its district heating network.
This network delivers enough heat to warm 30,000 modern apartments annually.
The broader Stockholm Data Parks initiative aims for by 2035, data centres will provide 10% of the city’s total heating supply.
Mäntsälä, Finland
A 15 MW data centre supplies waste heat so effectively that it covers 54% of the town’s district heating needs (≈ 20 GWh) in 2018.
Result: 11% reduction in district heating prices, significantly increasing local affordability.
Meta in Odense (Denmark)
Meta’s hyperscale data centre in Odense has been channeling its excess heat into the local district heating system since 2020, covering 11,000 households.
Google in Finland
Google operates a data centre in Finland whose cooling system leverages sea water, enabling the capture and reuse of heat—heating 80% of local homes.

Broader Trends & Insights
Nordic leadership: Several Nordic nations—especially Sweden, Denmark, and Finland—are pioneers in integrating data-centre waste heat into urban heating infrastructure.
In Sweden, district heating and heat pumps now fulfill over 75% of the country’s energy demand; this includes recovered heat from data centres.
In the UK, heat-network penetration remains low (~2% of homes), but data-centre heat reuse could change this—potentially saving energy and driving £100 billion in investment by 2050, according to analysis.
Technology such as multi-stage heat pumps can upgrade low-grade heat (30–40 °C) to district heating temperatures of 60–90 °C with a Coefficient of Performance (COP) of 3–6×.
