Finally, some good usage — this Danish data center is providing heat to power thousands of household radiators

• Meta’s Danish facility converts server heat into household heating for thousands
• Odense uses existing infrastructure to transform wasted data center energy
• Heat pumps help raise server warmth to temperatures suitable for homes

A data center operated by Meta in Odense, Denmark is channeling its cooling heat straight into nearby homes.

Server operations typically send almost all of their electricity out as warmth, with one industry estimate placing that figure near 90%.

Most facilities simply vent that energy skyward, but the Odense site routes it through the city's own heating infrastructure instead.

How the recovery system actually works

Roughly 40% of a data center's total energy consumption goes toward cooling servers, and nearly all of it is released as low-grade heat.

That heat arrives too cool for direct use, since server exhaust never reaches temperatures high enough to warm buildings on its own.

Water from the municipal district-heating network runs through...
