Data centers use a lot of power, consumed by two main usages: The power required to run the actual equipment and then the power required to cool the equipment. Power efficiency reduces the first category.

Cooling cost reduction through natural means includes location decisions: When the focus is avoiding good fiber connectivity, power grid connections, and people concentrations to manage the equipment, a data center can be miles away from the users. Mass data centers like Google or Facebook don't need to be near population centers. Arctic locations that can use outside air, which provides cooling, are becoming more popular.<ref>{{cite web|url=http://www.gizmag.com/fjord-cooled-data-center/20938/|title=Fjord-cooled DC in Norway claims to be greenest|date=23 December 2011 |access-date=23 December 2011}}</ref>

Singapore lifted a three-year ban on new data centers in April 2022.

Singapore's new data centers shall meet very strict green technology criteria including "Water Usage Effectiveness (WUE) of 2.0/MWh, Power Usage Effectiveness (PUE) of less than 1.3, and have a "Platinum certification under Singapore's BCA-IMDA Green Mark for New Data Centre" criteria that clearly addressed decarbonization and use of hydrogen cells or solar panels.<ref>{{Cite web |title=Singapore authorities invite applications for new data centers |date=20 July 2022 |url=https://www.datacenterdynamics.com/en/news/singapore-authorities-invite-applications-for-new-data-centers/}}</ref><ref>{{Cite web |title=BCA-IMDA Green Mark for Data Centres Scheme |url=https://www.imda.gov.sg/how-we-can-help/bca-imda-green-mark-for-data-centres-scheme |access-date=2024-09-18 |website=Infocomm Media Development Authority |language=en}}</ref><ref>{{Cite web |date=2024-05-30 |title=Singapore to free up 300MW for data centres |url=https://www.capacitymedia.com/article/2davfx8ylwhh1au8329kw/news/singapore-to-free-up-300mw-for-data-centres |access-date=2024-09-18 |website=Capacity Media |language=en}}</ref><ref>{{Cite web |title=4 Proposals Selected from Data Centre Application |url=https://www.imda.gov.sg/resources/press-releases-factsheets-and-speeches/press-releases/2023/four-data-centre-proposals-selected-as-part-of-pilot-data-centre-call-for-application |access-date=2024-09-18 |website=Infocomm Media Development Authority |language=en}}</ref>

====Direct current data centers====
{{See also|Power distribution unit|Inspur Server Series|Switched-mode power supply|Off-the-grid}}
Direct current data centers are data centers that produce [[direct current]] on site with [[solar panel]]s and store the electricity on site in a [[battery storage power station]].  Computers run on direct current and the need for [[Power inverter|inverting]] the [[Alternating current|AC]] [[Electrical grid|power from the grid]] would be eliminated. The data center site could still use AC power as a grid-as-a-backup solution.  DC data centers could be 10% more [[Electrical efficiency|efficient]] and use less [[floor space]] for inverting components.<ref>[https://www.datacenterdynamics.com/en/opinions/could-dc-win-the-new-data-center-war-of-the-currents/ Could DC win the new data center War of the Currents?]</ref><ref>{{cite web | url=https://datacenters.lbl.gov/direct-current-dc-power | title=Direct Current (DC) Power &#124; Center of Expertise for Energy Efficiency in Data Centers }}</ref>
