Greenest Data Centers

The Information and Communications Technology (ICT) sector accounts for 2% of global carbon emissions including 0.3% from data centers. US data centers consume 1.5% of the country’s electricity. Therefore, many data centers feature designs to maximize energy efficiency and minimize environmental impact. A list of five of the greenest data centers in the world follows.


  • Green Mountain Data Center – There are two Green Mountain Data Centers in Norway; one in Stavanger and the other in Telemark. Both have achieved ISO 9001, ISO 14001, and Uptime Institute Tier 3 certifications. Stavanger is located deep inside a mountain at a former NATO site, and Telemark is near multiple hydropower plants. The data center serves finance, IT, government, health, O&G (a heavy civil construction firm), and others.
  • Verne Global Keflavik Facility – This carrier neutral, colocation data center is in Keflavik, Iceland. The site uses 100% carbon neutral power and natural cooling. Verne Global offers scalable solutions to address power requirements. Their clients include BMW, VW, DeepL, and the Earlham Institute.
  • HP’s Wynyard, England Data Center This site was a conversion of an existing 30,000 sq ft warehouse. A design goal was to increase energy efficiency without sacrificing quality and reliability. This data center has a pressure free cooling system with minimum use of chillers. This required wider operating conditions for the IT equipment. Air plenums, to permit large volumes of low-velocity air to cool the equipment, sit below the data halls. The cooling fans use less than 5% of the total facility load.
  • General Electric’s Louisville Facility The GE data center, built in 2011, has a LEED Platinum certification. The data center is 34% more efficient than similar facilities. High-density servers reduced space by 50%, and ultra-low-flow fixtures reduced water consumption by 42%.
  • Apple’s Maiden, NC & Prineville, OR Facilities – Apple’s data center in Maiden, NC is a 500,000 sq ft facility. It uses 100% renewable energy from its 300-acre site containing three solar farms and a 10-megawatt fuel cell installation. In April 2017, Apple disclosed a deal to buy 200 megawatts of power for its Prineville, OR data center from the Montague Wind Power Project in Gilliam County. It also purchases power from a 56-megawatt project called Solar Star Oregon II and it generates hydroelectric power from a project on the Deschutes River. In addition, Apple uses treated water from the Prineville sewage system to cool equipment.
