A political backlash against AI data centers is accelerating heading into the 2026 midterms, with fifteen red and blue states now having banned or delayed new data center construction amid fears over water consumption and strain on local electric grids. More than 200 bills addressing data centers were introduced across all 50 states in 2025, and over 40 became law, according to tracking cited by industry publications, while more than $130 billion in planned projects were delayed or abandoned in just the first quarter of 2026.
Why Water, Not Just Power, Became the Flashpoint
For years, the loudest objections to data centers focused on electricity demand and rising utility bills. In 2026, water has become an equally combustible issue. The global data center sector consumed water in 2023 roughly equivalent to what the entire US thermoelectric power industry uses in a single day, an estimated 132.4 billion gallons, according to research cited by Heatmap News. Evaporative cooling systems, which many large AI training facilities rely on to keep servers from overheating, can consume enormous volumes of fresh water that would otherwise go to agriculture, drinking supplies or industrial use.
Ground Zero: Iowa, Wisconsin and the Southwest
Google’s data center in Council Bluffs, Iowa consumed more than 1 billion gallons of water in 2024 alone through evaporative cooling, based on figures reported by Heatmap. Microsoft’s contested Mount Pleasant, Wisconsin campus, sited near Lake Michigan, could eventually draw as much as 702,000 gallons on peak days, or roughly 8.5 million gallons annually, even though the facility was designed with more than 90% closed-loop cooling to limit consumption. In the Southwest, Texas officials estimate data centers could account for 3% to 9% of statewide water demand by 2040, a projection that has fueled community protests from Arizona communities worried about groundwater depletion to residents in the Netherlands raising similar alarms about a different but comparable AI infrastructure buildout.
Company Pledges Versus Community Skepticism
The largest cloud and AI companies have made public water-stewardship commitments. Google has pledged to replenish more water than it consumes globally by 2030 and is among the few tech giants voluntarily disclosing facility-level water data. Amazon says it has reached roughly 75% progress toward becoming ‘water positive.’ Purdue University researcher Yi Ding said the threat to local water supplies from data center growth is ‘significant,’ while Oxford University’s David Mytton has pushed back on some of the alarm, arguing water is ‘often brought up as primary concern when it’s less important’ compared to grid strain and land use. That split among researchers mirrors the divide between residents demanding moratoriums and state economic-development officials courting data center investment for jobs and tax revenue.
Washington Wades In
The controversy has reached the federal level. Utilities and data center developers joined Trump administration officials at the Environmental Protection Agency for an event promoting a voluntary ‘Ratepayer Protection Pledge,’ an industry-backed framework intended to ensure that the costs of AI infrastructure, including water and grid upgrades, are not simply passed on to nearby residents’ utility bills. Critics argue a voluntary pledge lacks teeth compared with the binding building moratoriums that states like Georgia and Virginia have already begun weighing.
The Price Tag of Fixing the Problem
A study from researchers at UC Riverside and Caltech estimated that new water infrastructure needed to support data center growth could cost as much as $58 billion over four years. Some in the industry argue the water problem is ultimately solvable through technology, such as air-cooled or liquid-immersion systems that dramatically cut fresh-water draw, as outlined in a July 2026 report from the Information Technology and Innovation Foundation. That optimistic framing contrasts with the political reality on the ground, where more than 20 states are actively weighing bans or moratoriums rather than betting on future cooling-technology upgrades.
What to Watch Next
With the 2026 midterms approaching, data centers are shaping up to be an unusually bipartisan flashpoint, uniting rural conservative communities worried about agricultural water rights with urban progressives concerned about utility costs and environmental justice. Expect more state legislatures to introduce disclosure mandates forcing companies to report facility-level water use, following Google’s lead, and more court challenges as developers contest local moratoriums. How Microsoft’s Wisconsin project and similar contested sites in Georgia and Arizona are ultimately resolved could set the template for how far communities can push back against the AI infrastructure boom before federal or state governments intervene with binding rules rather than voluntary pledges.
