===Energy reuse===
It is very difficult to reuse the heat which comes from air-cooled data centers. For this reason, data center infrastructures are more often equipped with heat pumps.<ref>{{cite web|url=https://stockholmdataparks.com/wp-content/uploads/white-paper-cost-efficient-and-sustainable-data-center-cooling-2017-01-23-1.pdf|title=Data Center Cooling with Heat Recovery|website=StockholmDataParks.com|date=January 23, 2017|access-date=2018-11-16|archive-date=2017-03-25|archive-url=https://web.archive.org/web/20170325212318/https://stockholmdataparks.com/wp-content/uploads/white-paper-cost-efficient-and-sustainable-data-center-cooling-2017-01-23-1.pdf|url-status=live}}</ref>

An alternative to heat pumps is the adoption of liquid cooling throughout a data center. Different liquid cooling techniques are mixed and matched to allow for a fully liquid-cooled infrastructure that captures all heat with water. Different liquid technologies are categorized in 3 main groups, indirect liquid cooling (water-cooled racks), direct liquid cooling (direct-to-chip cooling) and total liquid cooling (complete immersion in liquid, see [[server immersion cooling]]). This combination of technologies allows the creation of a [[thermal cascade]] as part of [[temperature chaining]] scenarios to create high-temperature water outputs from the data center.{{citation needed|date=February 2025}}
