Microsoft unveiled a new data center design that consumes no water to cool a facility’s chips and servers and could save millions of liters of water amid scrutiny over the climate impact of artificial intelligence.
First rolled out in August, the new data center design “consumes zero water for cooling” by recycling it through a “closed loop” system that circulates water between servers and “chillers” that remove heat without the need to be topped up, Microsoft said in a Dec. 9 <a data-ct-non-breakable="null" href="https://www.microsoft.com/en-us/microsoft-cloud/blog/2024/12/09/sustainable-by-design-next-generation-datacenters-consume-zero-water-for-cooling/" rel="null" target="null" text="null" title="null">post</a>.
“By adopting chip-level cooling solutions, we can deliver precise temperature control without water evaporation,” the company said.&nbsp;
It added that water would still be used for onsite necessities like toilets and kitchens, but the design “will avoid the need for more than 125 million liters of water per year per data center.”

Microsoft said its current data centers will stay with air and water-cooled tech, but its new projects in Arizona and Wisconsin will pilot the new system in 2026.
It added that in August, it started to use its new “zero-water evaporation” system as the primary cooling system for new data centers that will start to come online in late 2027.
