The 2026 U.S.-Iran War and the Global Energy Crisis

Chapter 30: Data Centers, Semiconductors, and the Militarization of Power Consumption

30.1 Data Centers Are Electricity-Consuming Military Supply Bases

Early morning on March 1, 2026, in Abu Dhabi, United Arab Emirates. Two hypercale data centers belonging to Amazon Web Services (AWS) were struck simultaneously by Shahed suicide drones from the Iranian Revolutionary Guard Corps (IRGC). At the same moment, an AWS facility in Bahrain suffered shrapnel damage from nearby explosions. Concrete walls cracked, emergency suppression systems activated, and water cascaded onto server racks. Within minutes, mobile banking applications from Abu Dhabi Commercial Bank, Emirates NBD, and First Abu Dhabi Bank went offline. Payment platforms stopped working, ride-hailing services went dark. Across the UAE, people could not pay for a coffee at a cafe or call a taxi from the airport. Amazon was forced to mark regional service status as "disrupted" for days afterward.

This was a historic first. A national military had intentionally struck a private big-tech company's data center. State news agency IRNA published a message immediately after the attack, listing Amazon, Microsoft, Palantir, and Oracle by name and declaring "Enemy Technology Infrastructure: Iran's New Target." The IRGC made its reasoning explicit. AWS hosted the U.S. Department of Defense's AI systems, and Anthropic's Claude model was being used for military operations analysis and target identification against Iran.

That claim was not fiction. The Washington Post reported that the U.S. military used AI tools to strike more than 1,000 targets within the first 24 hours of Operation Epic Fury. Palantir's Maven Smart System had Anthropic's Claude embedded within it. This system semi-automatically ranked targets by strategic importance and even drafted legal justifications for each strike. U.S. Central Command (CENTCOM) used this system to process satellite imagery, signals intelligence, and communications intercepts in real time to extract target coordinates. Pentagon Chief Information Officer Kristin Davis officially acknowledged at a Senate Armed Services Committee hearing that "this system is currently being utilized in ongoing operations."

One fact emerged here. What we call the "Cloud" is not a cloud. It is a building made of tens of thousands of tons of concrete and steel, a metal structure arrayed with hundreds of thousands of servers, a physical facility that consumes electric power equivalent to a coal-fired power plant without pause. Inside this facility, America's kill chain was operating,the process from target detection to strike. From Iran's perspective, attacking this building was fundamentally no different from bombing an ammunition depot.

International law scholars' interpretations aligned with Iran's logic. Harvard Law School visiting professor Ioannis Kalpouzos stated, "As long as a data center executes Pentagon's JWCC (Joint Warfighting Cloud Capability) contracts, that facility becomes a legitimate military objective." Article 52, Paragraph 2 of the Additional Protocols to the Geneva Conventions classifies facilities that make effective contribution to military action as lawful military objectives. The criterion is function, not proportion. If only one cluster out of 100,000 servers runs military AI, the entire building can become a target. Logical separation through virtual machines or availability zones means nothing before a physical strike. When a missile hits the building, military servers and civilian banking servers are destroyed together.

The question this incident raised was this: Should data centers be defended like military bases? If so, by whom and at what cost?

Air defense of data center-dense regions had already become a practical problem. James Shortz of the Royal Institute of International Affairs at Chatham House said, "Deploying air defense systems like the Iron Dome next to oil facilities or government infrastructure is already standard practice." The real question, he noted, was how high to rank data centers on the critical infrastructure list. The United States includes data centers among 16 critical infrastructure sectors; the United Kingdom designated data centers as critical national infrastructure in 2024.

The issue is scale. According to the International Energy Agency (IEA), global data center electricity consumption in 2024 was approximately 415 terawatt-hours (TWh). This represented roughly 1.5 percent of global electricity consumption. The IEA projected this figure would more than double to 945 TWh by 2030, equivalent to Japan's annual electricity consumption. In the United States alone, data center electricity demand is expected to increase 133 percent, from 183 TWh in 2024 to 426 TWh in 2030.

The driver of this explosive growth is artificial intelligence. The IEA identified AI as "the most significant driver of this growth." Electricity demand for AI-optimized data centers will increase more than fourfold by 2030. By 2030, data centers will account for nearly half of the increase in U.S. electricity demand. An era is coming when more electricity goes into data processing than into aluminum smelting, steel production, cement manufacturing, and chemical production combined.

Virginia's "Data Center Alley" already consumes 26 percent of the state's entire electricity supply in data centers. In Ireland, 79 percent of Dublin's power goes to data centers. GPUs (graphics processing units) used in AI servers consume two to four times more electricity than conventional CPUs. Servers consume power and generate heat. Cooling systems that dissipate that heat consume more power. In efficient hyperscale facilities, cooling accounts for 7 percent of total power; in inefficient facilities, it exceeds 30 percent.

When power supply cuts off, cooling stops, and when cooling stops, servers overheat and shut down within minutes. Uninterruptible power supplies (UPS) and diesel generators exist, but with the Strait of Hormuz blockade making diesel supply itself unstable, backup generators cannot run for more than a few days.

The March 1 AWS strike set a precedent. Data Center Dynamics' analysis summarized it this way: "The data center industry has risk models for cyber incidents, operational failures, and natural disasters. It has no risk model for reclassification as a military objective under international law."

An era had begun in which these electricity-consuming buildings became targets for missiles. Amazon's stock price actually rose roughly 3 percent immediately after the attack. Wall Street analysts judged that demand would grow to abandon single-region deployments and shift to multi-region infrastructure, which would drive cloud revenue growth. The irony of warfare becoming business opportunity. Data centers had become the tool of war, the target of war, and simultaneously an industry profiting from war.

30.2 Chip Production and Weapons Systems

On March 2, 2026, in the Ras Laffan industrial city in Qatar. After Iranian drones and missiles struck this facility, state-owned QatarEnergy announced it was halting operations at its natural gas processing and export facility. Ras Laffan is the world's largest LNG export hub. Yet this facility produces a byproduct in its natural gas processing: helium. Qatar produces approximately one-third of the world's helium. In 2025 alone, roughly 63 million cubic meters. When Ras Laffan stopped, that volume disappeared from the market.

Few understand why helium matters. Most know it only as the gas that fills balloons. In semiconductor factories, helium is a matter of survival. When manufacturing semiconductors, there is an etching process that inscribes microscopic circuits onto silicon wafers. This process requires maintaining a constant temperature on the wafer. Jacob Feldgoise of Georgetown University's Center for Security and Emerging Technology explained: "During the etching process, heat must be removed from the wafer. Helium is a gas with superior thermal conductivity, so helium is blown onto the back of the wafer to extract heat rapidly and uniformly." Helium is essential in photolithography processes as well,the technique that uses light to print precise circuit patterns on chips. In manufacturing chips below 5 nanometers, helium is used for leak detection. No substitute material exists for helium. The Semiconductor Industry Association already warned in 2023: "A halt to helium supply will create a shock to the global semiconductor manufacturing industry."

That warning became reality. South Korea produces approximately two-thirds of the world's memory semiconductors. The two largest memory chip manufacturers in the world, Samsung Electronics and SK Hynix, are both located in South Korea. According to the Korea International Trade Association (KITA), South Korea depended on Qatar for 64.7 percent of its helium imports in 2025. Fitch Ratings directly identified this vulnerability in its report on South Korea.

Helium was not the only concern. There is an element called bromine, a chemical compound used in semiconductor circuit formation. South Korea was dependent on Israel for approximately 90 percent of its bromine imports. About two-thirds of the world's bromine production is concentrated along the Dead Sea coast in Israel and Jordan, and Israel was a combatant in the war with Iran.

At the South Korean National Assembly, ruling party member Kim Young-bae warned that the Iran War could threaten the supply of critical semiconductor materials. The South Korean Ministry of Trade, Industry and Energy began investigating supply and demand conditions for 14 critical semiconductor materials and equipment items with high Middle Eastern dependency.

The physical properties of helium compounded the problem. Helium atoms are the smallest of all elements. In gaseous form, they escape from even the most precise containers. So Qatar cools helium to extreme temperatures to liquefy it, then transports it by ship in specially insulated cryogenic containers. The storage life of these containers is 35 to 48 days. After that, liquid helium gradually evaporates, returning to gaseous form and drifting into the atmosphere. Stockpiling is virtually impossible with this substance. Helium specialist Phil Conblues explained, "Approximately one-third of the world's cryogenic helium ISO containers are isolated around and within Qatar," adding, "Even if the conflict ends, it will take a minimum of three months just to redeploy this equipment." He added a remark: "If the world loses one-third of its helium supply, there is no way to compensate."

This supply chain bottleneck directly connects to weapons system production. Taiwan's TSMC manufactures approximately 90 percent of the world's cutting-edge logic semiconductors on a contract basis. Chips from Nvidia, Apple, AMD, and Qualcomm all come from here. It is also the sole supplier of AI accelerators. Yet Taiwan imports 97 percent of its energy. Its natural gas reserves amount to only 11 days of supply. Qatar accounts for approximately one-third of Taiwan's LNG imports. If the Strait of Hormuz closes and Qatar's production stops, Taiwan's power supply falters, and when power falters, chip production falters.

Semiconductors are the brain of modern weapons systems. Nothing works without them,not the avionics of the F-35 stealth fighter, not the guidance system of the Tomahawk cruise missile, not the air defense radar of the Aegis destroyer, not the commercial drones flying over the Ukraine front lines. The United States could strike over 1,000 targets within the first 24 hours of Operation Epic Fury because AI processed information and classified targets, that AI ran on GPUs, and those GPUs were manufactured in TSMC's factory. Without helium, that factory stops.

The chip supply chain is the most sophisticated, most concentrated, and most vulnerable industrial chain in human history. Companies that design chips are located in the United States. Companies that manufacture those designs are concentrated in Taiwan and South Korea. Only the Netherlands' ASML manufactures extreme ultraviolet (EUV) lithography equipment. China controls rare earth element processing. Break any single link in this chain, and weapons production lines across the globe stop.

The United States was not unaware of this vulnerability. Through the CHIPS Act, it is pouring astronomical subsidies into building semiconductor factories on American soil. Simultaneously, it continues to tighten export controls on AI chips. In January 2026, the U.S. Commerce Department's Bureau of Industry and Security published a final rule modifying its licensing policy for high-performance AI chip exports to China. House Foreign Affairs Committee Chair Brian Mast pushed the AI OVERWATCH Act, demanding congressional veto power over AI chip export licenses. The bill would treat AI chip exports the equivalent of weapons sales. "We need to do the same thing for chips that we do for fighter jets," Chair Mast said.

Export controls on AI chips are fundamentally the same act as a navy blockading an enemy port. The semiconductor export restrictions targeting China that began in 2022 are an attempt to strangle the growth of China's military AI capability at its source. According to Georgetown University analysis, "The U.S.-led alliance controls nearly every critical node in the advanced semiconductor supply chain." Preserving this structural advantage is a cornerstone of American technology strategy.

Yet as the Iran War unfolded, a paradox emerged: the war America started began to shake the structural advantage America had created. The Strait of Hormuz blockade cut off Qatar's helium, Qatar's helium disruption threatened chip factories in South Korea and Taiwan, and America's war was attacking its own supply chain that produced American weapons.

Taiwan had treated this vulnerability as a paradoxical security asset called the "Silicon Shield." If TSMC is destroyed, the global economy stops, so the United States will surely protect Taiwan, the reasoning went. But the lesson from 2026 was different. An adversary does not need to invade Taiwan directly; closing a single strait is enough to slowly kill Taiwan's chip factories.

The Carnegie Endowment for International Peace concluded its analysis this way: "The Iran War did not create South Korea's energy vulnerability. It simply revealed how dangerous that vulnerability had become."

30.3 Energy and Technology Become One Battlefield

South Korea's stock market fell 18 percent over four days in the first week of March 2026, its worst decline since the 2008 financial crisis. More than 500 billion dollars in market capitalization evaporated. The Carnegie Endowment for International Peace analyzed the cause as "a cascading transmission of energy security disruption into South Korea's semiconductor-centered stock market."

Here a structure emerges. When the Strait of Hormuz closes, LNG prices spike. When LNG prices spike, electricity rates rise. When electricity rates rise, chip production costs rise. When chip production costs rise, data center operating costs rise. When data center costs rise, the cost of training and running AI models rises. When AI costs rise, a nation's defense spending that uses that AI militarily rises. An energy shock created by one strait,transmitted through chains of technology and security,rearranges the competitive position of nations across the entire globe.

The most critical variable in this chain is electricity price. National competitiveness in the AI era will be determined by "who can supply the cheapest and most stable electricity to data centers." The IEA's 2025 declaration that "electricity is becoming the new oil" was not metaphor but a description of structural change.

In the United States, data center electricity demand will account for nearly half the increase in power demand by 2030. How to meet this demand has become a national security question. It was no accident that the Inflation Reduction Act and the CHIPS Act were advanced simultaneously during the Biden administration. To attract semiconductor and battery factories to your own country, you must be able to economically supply the enormous electricity those factories will consume. A CHIPS Act without factories is paper. A factory without electricity is scrap metal.

The issue is power quality. Data centers tolerate no voltage drops for even a second. The share of renewable energy is growing, yet solar and wind are intermittent. If the wind does not blow, electricity does not flow. If the power grid destabilizes, a data center can shut down without enemy physical attack.

This is why both big-tech companies and the Department of Defense are focusing on small modular reactors (SMRs). Microsoft and Google are pursuing plans to build SMRs next to data centers, creating independent micro-grids that do not depend on external power networks. This is not energy policy,it is security policy, a defense system to protect core computing capacity from enemy cyberattacks or power grid strikes.

Taiwan's TSMC set a goal of sourcing 100 percent renewable electricity by 2040. This is not climate policy but energy security strategy. As long as it depends on imported fossil fuels, a single chokepoint like the Strait of Hormuz can shut down the factory, a fact the 2026 crisis proved. The Carnegie Endowment applied the same lesson to South Korea: "To preserve semiconductor leadership, you must first protect the energy system that supplies electricity to that semiconductor."

The energy shock created by the Iran War revealed an interesting asymmetry. While the United States and its allies struggled with soaring energy prices and supply chain disruptions, China walked a different path. As U.S. sanctions on Russia eased, cheaper Russian energy flowed to China in greater quantities. China maintained the stability of its power supply by continuously operating its own coal-fired power plants. In the helium market, room emerged for Russian helium to enter the Chinese market. According to CNBC analysis, "If Qatar's disruption persists, Russia is positioned to expand its role as China's helium supplier."

A structure took shape: America starts a war that creates an energy crisis for America's allies, that energy crisis shakes the semiconductor supply chain, and in the confusion of that disrupted chain, China gains reflected benefits. The gap between the intention of war and its consequences had rarely been wider.

In Virginia, grassroots opposition to data center construction was spreading. Concerns about power grid overload and water resource depletion were causing delays and cancellations of large data center projects. In the Middle East, AWS's investment in Saudi Arabia became uncertain. Brookfield Asset Management stated it would maintain its 20 billion dollar data center partnership with Qatar, yet investment appetite for new large-scale projects had frozen. Euronews reported that "the Middle East's cloud and AI strategy has become threatened in an alarming way."

In the twentieth century, oil-producing nations (petro-states) stood at the center of geopolitics. In the twenty-first century, nations capable of supplying cheap electricity in unlimited quantities to power AI and data centers will take that place. The era when aircraft carriers were dispatched to protect oil shipping routes is giving way to an age centered on securing uranium, natural gas, and power grid cybersecurity to supply stable electricity to a country's own data centers.

An age in which failure in energy infrastructure leads to failure in technology, and failure in technology results in military inferiority. An age in which the price tag on barrels determines the future of watts. When the 21 miles of the Strait of Hormuz closed, what the world witnessed was not merely an oil crisis. It was the landscape of the twenty-first century in which energy, technology, and security have become so entangled on a single battlefield that they cannot be separated.
