They’ve been shown to raise electricity bills, pollute drinking water, do little to boost local employment while threatening millions of jobs in a variety of industries, and top executives have warned that the technology they support could wipe out all of humanity by the end of the decade. But rather than take widespread public opposition to artificial intelligence data centers at face value, House Speaker Mike Johnson (R-La.) announced he had […]

The post US House speaker sees AI data center worries as ‘Chinese psyop’ appeared first on Asia Times.

Concerns about the water and energy demands of data centers have become prolific in recent weeks. But debates about their impact often overlook the rapid advances in cooling technology and cleaner energy that are already having an impact.

However, data centers’ resource consumption should be front and center of the AI conversion, as it is set to grow rapidly. By 2030, data centers’ water and energy consumption will double as AI demand leads to rapid construction of the infrastructure.

But data centers will not cause the world to run out of water or energy. Water- and energy-saving technologies already in use are reducing their impact, while Shanghai’s groundbreaking underwater data center demonstrates how innovative design can limit water, energy and land use.

Data centers have underpinned the internet since its founding. Apps, email, file storage and cloud services all run through them.

Modern AI workloads, however, have transformed their power demands beyond recognition. Today a single AI data center can match the electricity consumption of 100,000 homes, making them a significant drain on local energy grids, especially if a region is susceptible to shortages.

Data centers’ energy consumption is only rising as more are built across the world. In the US, data centers could increase from 4.4% to 12% of national electricity usage by 2028 — that is equivalent to adding eight New York Cities to the American grid.

Data centers also consume large amounts of water in two main ways. Water is used directly to cool servers and storage systems, which generate considerable heat, and indirectly to produce electricity at fossil fuel power plants where it is heated into steam to drive turbines.

In the UK, data centers have been estimated to use up to eight times as much water as average on hot summer days, underlining how their impact can rise when local resources are already under strain.

As the effects of climate change intensify, the location of data centers, and methods to reduce their water and energy consumption, are becoming ever more important.

Fortunately, resource-saving measures are already being implemented. Data centers on land use closed-loop cooling systems that recycle water rather than continually evaporating it. This can reduce freshwater use by up to 70% compared to traditional open evaporative methods.

China has also pioneered a revolutionary new type of data center in Shanghai: wind-powered, and underwater. The facility, which began full commercial operations in May 2026, uses seawater as a coolant instead of using refrigerated fresh water as land-based data centers do, reducing the electricity required to cool the computers.

It uses at least 30% less electricity than traditional data centers, and offshore wind turbines reduce reliance on fossil fuels and cut the data center’s carbon emissions. Innovative solutions such as these will go a long way to reducing data centers’ resource consumption.

AI is also part of the solution to data centers’ draw on resources. AI can optimise electricity grids and shift computing workloads towards periods when cleaner energy is more efficient, making energy use more effective overall. AI can also anticipate fluctuations in demand and adjust energy consumption accordingly, reducing waste.

It might sound obvious, but some areas are just better equipped to accommodate a data center than others. For example, facilities in hot or water-stressed regions will impose a heavier burden on resources than those supplied by cleaner energy with plentiful water and located in cooler climates.

AI’s growing demand for data centers will increase electricity and water consumption, that is true. But it does not mean the technology will exhaust regional or global supplies of either resource.

The AI boom and the infrastructure buildout accompanying it are well underway. To manage its impact, the industry needs to plan ahead. Cleaner energy, efficient cooling, and sites that have significant water and energy supplies will all limit the infrastructure’s drain on resources.

More than a decade ago, a group of snipers shot up an electrical substation in Silicon Valley, striking power transformers and disabling the substation for nearly a month. The shooters were never identified; similar substation shootings, some by neo-Nazis, have taken place since. The longer Christopher Cox studies the American power grid—looking at aging infrastructure and ongoing transformer shortages, specialized manufacturing and rising demand, the massive energy consumption of data centers and whiplash usage of large language models—the more vulnerable it seems. “Somehow, we’ve made the industrial equivalent of a Fabergé egg the linchpin of our civilization,” Cox writes. “What would happen if someone started breaking them?”

The hope of restoring the grid would fade as fossil fuel supplies were exhausted, because so many utilities rely on them to “black-start” their generating units. A 2010 report called “High-Impact, Low-Frequency Event Risk to the North American Bulk Power System,” prepared by the Energy Department and NERC, condensed the entire disaster movie that would follow into a single paragraph: “The supply of food, water and fuel would degrade within days. The facile communication of information to the general population would be greatly complicated by the loss of cellphones, internet access and television. The economy would virtually shut down as electronic transactions could no longer be processed. After several days, widespread social unrest and confusion would ensue.” Thirsty, starved, dirty and surrounded by the useless machines we once depended on, we would be lucky if our misery ended at “confusion.”

At Dugway Proving Ground in Utah, on ground the Army’s own contracting documents describe as previously used for grazing, a company owned by two of the largest investment firms in the world is preparing to build a data center.

That site sits about an hour’s drive from the nearest community, on the installation where the U.S. military conducts its primary chemical and biological weapons testing. Three parcels there total roughly 3,466 acres. One of them, about 1,201 acres, is already spoken for.

It is one of at least a dozen military installations the Army and the Department of the Air Force have opened to commercial data center developers over the past year and a half. Two of those deals are real; the rest are still proposals.

Land-for-Computing

In late March, the Army conditionally selected two companies to enter exclusive negotiations to build and operate commercial hyperscale data centers on Army land.

Carlyle, the global investment firm, was picked for roughly 1,384 acres at Fort Bliss, Texas. CyrusOne, a data center operator jointly held by funds managed by KKR and BlackRock, was picked for the parcel at Dugway. Each project is estimated to cost about $2 billion, according to the Financial Times.

The companies will be responsible for financing, building, operating, maintaining and eventually decommissioning the facilities, the Army said, on what it called “underutilized but non-excess Army land at no upfront cost to taxpayers.” In exchange for the land, the service gets access to computing power.

It all runs through the Army’s Enhanced Use Lease program, driven by a Trump executive order directing agencies to open non-excess federal land to data center development. The U.S. Army Corps of Engineers is handling lease negotiations and environmental review.

“AI is a strategic asset for the Army,” Army Secretary Dan Driscoll said in the March announcement. “It is a force multiplier, supports future transformation and requirements, keeps the Army ahead of our adversaries, and generates resiliency across the force.” Driscoll told the Wall Street Journal that the Fort Bliss facility would be “the first hyper-scale data center that the Pentagon has ever done.”

Which Bases and How Close to Housing?

Only Fort Bliss and Dugway have been awarded so far, and even those remain conditional, pending negotiation. Beyond them, federal contracting documents show the Army considering data centers at Fort Hood, Texas, and Fort Bragg, N.C.

The Department of the Air Force put out its own call in 2025 for private AI data center projects on unused land at Arnold Air Force Base, Tenn., Edwards Air Force Base, Calif., Joint Base McGuire-Dix-Lakehurst, N.J., Davis-Monthan Air Force Base, Ariz., and Robins Air Force Base, Ga.

More recently, it sought bidders for facilities at Joint Base Elmendorf-Richardson, Eielson Air Force Base and Clear Space Force Station in Alaska. Acreage varies enormously; for example, Fort Hood has 207 acres on offer. Fort Bliss has nearly seven times that.

Dugway is remote by design, although not every site is. Contracting documents show the Army weighing a parcel at Fort Hood within a half-mile of residential and commercial property, and several potential locations at Fort Bragg within one mile of civilian areas and a half-mile of civilian housing.

Proximity to the population is what has made data centers a heated topic in the civilian world. Nearly $156 billion in projects nationwide have been delayed or canceled after local opposition, according to Data Center Watch.

In Virginia, which holds the world’s highest concentration of the facilities, a state-funded study found residents’ monthly energy bills could rise by $14 to $37 by 2040.

Army Officials Say They’re Ready

“So I think the difference between us, the Army, doing a data center, and say Meta or Google, is we’re part of the communities that are there, and we are going to engage with them on a routine and regular basis to look for solutions that work for everyone, right?” Col. John Oliver, executive officer for Deputy Army Under Secretary Dave Fitzgerald, told Defense One. “Because, yes, we understand that there’s been consternation with data centers.”

Two requirements attached to these projects do not apply to commercial builds off base. Proposals must include net-zero water usage and a power plan that does not draw on the local electrical grid. Bidders were also required to describe plans for “local outreach and engagement” and to assess “any risks or opposition” to the project.

The Defense Department’s own procurement documents, obtained by the trade publication Data Center Dynamics, rate the water risk for the El Paso area as “Extremely High.” Data centers consume water to cool their servers. Fort Bliss is where the Army wants its flagship.

Army officials want the project to be a net contributor rather than a net drain. In the spring, Fitzgerald traveled to Fort Bliss for a listening session with the commander of the 1st Armored Division, community members, El Paso Water, El Paso Electric and Carlyle. One idea on the table is having the developer drill a new well to feed the city’s desalination plant, offsetting what the data center uses.

“We are encouraging Carlyle to do that, so actually make it net-positive,” Oliver told Defense One. “We don’t know if that’s an engineering solution that we can actually get to yet, but we’re actively working toward that as a part of the process.”

Darrell M. West, a senior fellow at the Brookings Institution who studies data center development, said the approach is sound, and that communities which have accepted the facilities tend to be the ones told the full details in advance.

“People want to know up-front, you know, where the energy is coming from, how much water is being used, how much the overall cost is going to be, and what the noise levels are,” West said.

Congress Not Settled

Rep. Cory Mills, a Florida Republican, secured a provision in the House version of the fiscal 2027 defense authorization bill. This bill bars the Defense Department from leasing land for data centers unless developers agree not to install equipment containing components made in China, Russia, Iran or North Korea. The restriction covers certain printed circuit boards, advanced semiconductors and chipsets the department considers a security risk.

“Honored to pass this amendment to protect our military installations from Chinese components being used in data centers on our installations,” Mills wrote on X.

The Army objected. The measure would create a “federal land penalty,” a service official told Federal News Network, imposing rules on companies building on installations that would not apply to identical projects built anywhere else. “We want Congress to incentivize companies to build on secure federal land, rather than creating barriers that drive them away,” the official said.

Rep. John Garamendi, a California Democrat, proposed requiring the Pentagon to evaluate a data center’s energy and water consumption, noise and light pollution, and effects on security and supply chains before finalizing any deal. House Armed Services Republicans rejected it.

“We’re not opposed to data centers,” Garamendi said. “We just want to make sure that if we’re going to put a data center on a federal facility, that federal facility is not going to be degraded by the data center.”

His questions were installation questions. “Is there encroachment on training and operations and the physical and supply chain of security?” he asked.

Senate Armed Services Republicans defeated a separate Democratic amendment that would have blocked leasing until the Pentagon finalizes a data center strategy. House appropriators, meanwhile, adopted language acknowledging that data centers “place significant strain on energy and water resources and communities have resisted such projects.”

Available Information

For anyone stationed at or living near one of these installations, several things are known for sure. Only two projects have been awarded, and both remain conditional. Fort Hood, Fort Bragg and the Air Force sites are solicitations, not commitments.
