The growth in synthetic intelligence is ushering in an environmentally aware shift in how information facilities function, as European builders face strain to decrease the water temperatures of their energy-hungry services to accommodate the higher-powered chips of corporations similar to tech large Nvidia.
AI is estimated to drive a 160% growth in demand for information facilities by 2030, analysis from Goldman Sachs exhibits — a rise that would come at a value to Europe’s decarbonization targets, because the specialised chips utilized by AI corporations are anticipated to hike the vitality use of the information facilities that deploy them.
Excessive-powered chips — also called graphics processing models, or GPUs — are important for coaching and deploying giant language fashions, that are a kind of AI. These GPUs want excessive density computing energy and produce extra warmth, which in the end requires colder water to help dependable cooling of the chips.
AI can eat 120 kilowatts of vitality in only one sq. meter of a knowledge heart, which is equal to the facility consumption and warmth dissipation of round 15 to 25 homes, in line with Andrey Korolenko, chief product and infrastructure officer at Nebius, who referred particularly to the deployment of Nvidia’s Blackwell GB200 chip.
“That is extraordinarily dense, and from the cooling standpoint of view you want completely different options,” he mentioned.
The issue we have with the chipmakers, is AI is now an area race run by the American market the place land rights, vitality entry and sustainability are comparatively low on the pecking order, and the place market domination is essential,” Winterson advised CNBC

Michael Winterson, chair of the European Knowledge Middle Affiliation (EUDCA), warned that decreasing water temperatures will finally “basically drive us again to an unsustainable scenario that we had been in 25 years in the past.”
“The issue we have with the chipmakers is [that] AI is now an area race run by the American market the place land rights, vitality entry and sustainability are comparatively low on the pecking order, and the place market domination is essential,” Winterson advised CNBC.
Main gear suppliers in Europe say that U.S. chip designers are calling on them to decrease their water temperatures to accommodate the warmer AI chips, in line with Herbert Radlinger, managing director at NDC-GARBE.
“That is surprising information, as a result of initially everyone from the engineering aspect anticipated to go for liquid cooling to run larger temperatures,” he advised CNBC, referring to the know-how of liquid cooling, which is claimed to be extra environment friendly than the extra conventional technique of air cooling.
‘Evolution dialogue’
Power effectivity is excessive on the European Fee’s agenda, because it seeks to achieve its purpose of lowering vitality consumption by 11.7% by 2030. The EU predicted in 2018 that vitality consumption of knowledge facilities may rise 28% by 2030, however the introduction of AI is anticipated to spice up that quantity two or threefold in some nations.
Winterson mentioned that decreasing water temperatures is “basically incompatible” with the EU’s not too long ago launched Power Effectivity Directive, which established a devoted information base for information facilities of a sure dimension to publicly report on their energy consumption. The EUDCA has has been lobbying Brussels to think about these sustainability considerations.
Power administration agency Schneider Electrical engages usually with the EU on the subject. Lots of the current discussions have centered on other ways to supply “prime energy” for AI information facilities and for the potential for extra collaboration with utilities, mentioned Steven Carlini, chief advocate of AI and information facilities and vp at Schneider Electrical.
European Fee vitality officers have additionally had exchanges with Nvidia to debate vitality consumption and using information facilities with regard to the effectiveness of energy use and that of chipsets.
CNBC has approached Nvidia and the Fee for remark.
“Cooling is the second-largest client of vitality within the information heart after the IT load,” Carlini advised CNBC in emailed feedback. “The vitality use will rise however the PUE (Energy Utilization Effectiveness) might not rise with decrease water temperatures regardless of the chillers having to work tougher.”
Schneider Electrical’s prospects which are deploying Nvidia’s Blackwell GB200 tremendous chip are asking for water temperatures of 20-24 levels Celsius or between 68 and 75 levels Fahrenheit, Carlini mentioned.
He added that this compares to temperatures of round 32 levels Celsius with liquid cooling, or of round 30 levels Celsius that Meta has urged for the water it provides to the {hardware}.
Ferhan Gunen, vp of knowledge heart operations for the U.Ok. at Equinix, advised CNBC that there are a selection of considerations about AI that Equinix has been discussing with its prospects.
“They wish to enhance the density of their servers, which is, they wish to have higher-power-using chips, or they wish to have extra servers,” she mentioned, including that the shift will not be “clear reduce.”
“It is actually an evolution dialogue greater than something,” Gunen mentioned.
Nvidia, which declined to touch upon the cooling necessities of its chips, announced a brand new platform for its Blackwell GPUs earlier this yr. It mentioned that the structure would allow organizations to run real-time generative AI on giant language fashions at as much as 25 instances much less value and vitality consumption in comparison with earlier know-how.
Liquid cooling would require a “reconfiguration,” Gunen defined, including that new information facilities are already coming prepared with this know-how. “Sure, larger density will imply extra energy use, and also will imply extra cooling requirement. However then the know-how is altering, so that you’re doing it in another way. That is why there’s a steadiness in all of this,” she mentioned.
Race for effectivity
Nebius, which has round $2 billion in money on its steadiness sheet after splitting from Russia’s Yandex, has said it will likely be one of many first to convey Nvidia’s Blackwell platform to prospects in 2025. The agency has additionally introduced plans to invest more than $1 billion on AI infrastructure in Europe by the center of subsequent yr.
Nebius’ Korolenko mentioned liquid cooling is a “first step,” the place value of possession will initially be worse earlier than enhancing over time.
“There is a large push to ship, however on the similar time, whenever you go to scale, you’ll want to have the power to decide on, to be economical and never sacrifice an excessive amount of. Energy effectivity is vital for the working prices. It is all the time a excessive precedence,” Korolenko mentioned.
Even earlier than a growth in demand for AI purposes hit the market, the information heart business in Europe was struggling to maintain tempo with the rising digital sector.
Sicco Boomsma, managing director of ING’s TMT staff, mentioned these concerned out there are “very delicate to energy” and that whereas Europe’s focus is on infrastructure, the U.S. has centered extra on increasing belongings in Europe the place energy is accessible.
“There is a great quantity of knowledge heart operators additionally coming from the U.S. which are aligning in an effort to be certain that their information heart infrastructure is according to the varied targets that the EU has as nicely, similar to being carbon impartial, similar to being environment friendly, on water utilization, sustaining biodiversity.”
“It’s a form of a race the place they wish to exhibit that their data is resulting in tremendous environment friendly infrastructure,” he mentioned.
