Microsoft is taking steps to reduce water consumption in its next-generation data centers. These new facilities will recycle water in a closed-loop system, cooling servers without requiring additional water after construction. This approach could save over 125 million liters of water per year for each data center.
The new design eliminates the need for water evaporation to cool servers, which has been a standard practice. Instead, liquid cooling solutions provide precise temperature control and reduce water use. The new data centers will operate in Arizona and Wisconsin starting in 2026. However, existing data centers will continue using current cooling systems that combine air and water technologies.
Microsoft reports a 39% improvement in water efficiency since 2021, with an average Water Usage Effectiveness (WUE) of 0.30 liters per kilowatt-hour. This progress is attributed to ongoing efforts to reduce water waste, expand operating temperature ranges, and utilize reclaimed water in areas like Texas and Singapore.
Despite these advancements, the "zero-water" claim may oversimplify the reality. The system still uses water for non-cooling purposes like restrooms and kitchens. Plus, switching to mechanical cooling increases energy consumption, raising concerns about sustainability trade-offs. While Microsoft says these systems will operate with renewable energy, critics question whether the added power demand offsets the water savings.
Microsoft’s efforts reflect a shift towards sustainable operations, but the balance between water efficiency and energy use remains a challenge. As the company expands its data center fleet, reducing environmental impact will require ongoing innovation and transparency.
