US Data Centers Face Public Backlash Over Water and Power Use

As artificial intelligence infrastructure faces mounting public scrutiny over intense water and electricity consumption, tech giants including Nvidia, Microsoft, Amazon Web Services, and Meta report utilizing closed-loop cooling systems that significantly reduce net water loss, though independent researchers highlight an ongoing thermal-electrical trade-off.

The Thermal Reality of Modern AI Hardware

Data centers running the infrastructure for modern artificial intelligence generate immense heat. Keeping these server warehouses operational requires aggressive temperature control. According to data from Rystad Energy, global data center water consumption reached 222 billion liters, or 59 billion gallons, in 2025. Without structural adaptations, industry consumption projections indicate a near-tripling to 644 billion liters by 2030.

To combat this trajectory, chip manufacturer Nvidia introduced a system known as DSX for designing and managing AI facilities. In a June report, Nvidia stated that the technology can eliminate water consumption almost entirely at select installations. The engineering mechanism relies on a closed-loop layout where liquid circulates directly through servers, moving as close as possible to silicon chips whose operating temperatures can exceed 80 degrees Celsius, or 176 degrees Fahrenheit.

Engineering Trade-Offs Between Water and Power

Deploying advanced cooling architecture does not eliminate resource consumption entirely; it shifts the burden from liquid to electrical grids. Independent data center researcher Andy Masley noted that a direct trade-off exists between water utilization and electrical consumption for thermal management. Curtailing direct water usage typically demands higher electrical loads because sealed-pipe liquid must still dissipate heat, frequently by forcing air across radiators.

Nvidia circumvents portions of this thermodynamic penalty by allowing circulating liquid to enter servers at a warmer baseline of 45 degrees Celsius. Industry figures from the Uptime Institute indicate that traditional closed-loop configurations operated closer to 32 degrees Celsius in 2024. Josh Parker, Nvidia’s head of sustainability, explained that this elevated starting temperature means simple circulating fans often suffice, though extreme climates and heat waves still require supplementary chilled air or evaporative techniques.

Cloud Providers Report Efficiency Gains Amid ESG Scrutiny

Hyperscale cloud operators are attempting to course-correct through infrastructure overhauls. Microsoft, Amazon Web Services, and Meta informed AFP that their operations rely on closed-loop liquid architectures yielding no net water loss. Sustainability disclosures from Microsoft and Amazon Web Services show that while total water volumes grew alongside massive infrastructure expansions between 2022 and 2025, water use efficiency improved by 25 percent and 37 percent, respectively.

Transparency across the sector remains uneven. SpaceX, which entered the data center space following its acquisition of artificial intelligence company xAI, has not published an environmental, social, and governance report. In June, ratings agency MSCI assigned SpaceX its lowest ESG rating.

Shaolei Ren, an engineering professor at the University of California, Riverside, pointed out market incentives driving these changes. Because water traditionally costs significantly less than electricity, corporations historically lacked strong financial motivations to curb liquid consumption based on utility bills alone. Instead, the current push toward conservation stems largely from public relations pressures and mounting community pushback across the United States.

The Hidden Resource Footprint

Upgrading legacy infrastructure presents another capital barrier. Retrofitting older facilities with modern cooling hardware involves substantial expense. However, Minh K. Le, who leads data center and hydrogen research at Rystad, emphasized that older facilities possess smaller footprints and lower computing capacities than the massive installations currently under construction, requiring less intensive cooling capacity overall.

Direct facility consumption tells only part of the story. Upstream resource expenditure includes the water required to generate electrical power and manufacture advanced server hardware and accelerators. In the United States, this hidden expenditure can double the direct water volume consumed on-site by a data center.
