AI Expansion Drives the U.S. to Explore Military Energy Resources

The rapid expansion of artificial intelligence (AI) is pushing the United States into uncharted territory in the search for reliable and massive energy sources—including tapping into the nation’s military energy infrastructure. What started as a race to develop smarter, faster computing systems has become a strategic challenge: how to power a digital future without overwhelming the grid. As AI’s power-hungry data centers proliferate, policymakers, tech leaders, and defense strategists are reconsidering energy solutions once reserved for military applications. Data Center Dynamics+1

Skyrocketing Demand: A Looming Energy Gap

Experts warn that the electricity required to support advanced AI systems is growing at an unprecedented pace. According to the Electric Power Research Institute (EPRI), total U.S. power demand for AI could exceed 50 gigawatts by 2030—a tenfold increase from current levels. To put this in perspective, just one powerful AI training model may consume the same electricity as a large power plant during peak use. S&P Global

In fact, projections suggest that by 2028, the demand from AI-related data centers could require more electricity than the entire nation of Spain consumes in a year—a staggering 325 terawatt-hours, according to a report by the Lawrence Berkeley National Laboratory. WIRED

With renewable energy capacity struggling to scale fast enough and traditional grids nearing saturation, officials are looking at unconventional sources—including decommissioned military nuclear reactors once used in submarines and aircraft carriers. Tom’s Hardware

Military Reactors: An Unexpected Power Solution

A bold proposal by U.S. startup HGP Intelligent Energy suggests repurposing retired naval nuclear reactors for civilian AI data centers. These reactors, previously installed on vessels such as the USS Nimitz and Los Angeles-class submarines, could generate between 450 and 520 megawatts of electricity—enough to power tens of thousands of homes or multiple large-scale AI facilities.

The plan, which would require backing from the Department of Energy and possibly legislative support, represents a fusion of defense-era technology with modern digital infrastructure needs. Proponents argue that naval reactors are proven, reliable, and capable of providing continuous 24/7 power without the intermittency issues that affect renewable sources. Importantly, U.S. Navy nuclear propulsion has operated for decades with a strong safety record and zero radiological accidents, according to industry analysts. Tom’s Hardware

Some experts believe this kind of initiative could accelerate U.S. competitiveness in the global AI race, especially relative to geopolitical rivals like China, which is also integrating AI with its energy systems as part of broader industrial strategy. Reuters

Why the Military Angle?

The interest in military-derived energy sources isn’t just about capacity—it’s about reliability and security. AI centers require uninterrupted power, and even minor grid instability can disrupt research and operations. Traditional reliance on coal, gas, or even intermittent wind and solar may not meet these strict uptime requirements. Military energy systems, especially nuclear microreactors, provide a steady baseline that can anchor a future AI-driven economy.

Moreover, the integration of military energy assets into civilian infrastructure reflects a broader trend of dual-use technology strategies. Many defense technologies have historically transitioned into commercial applications, from GPS to the internet. Analysts see AI energy challenges as another frontier where defense innovation may feed economic growth. Business Wire

Environmental and Social Trade-offs

However, this shift is not without controversy. As demand surges, older fossil-fuel-based power plants that were scheduled for retirement are returning to service to avoid blackouts, particularly in regions like the PJM Interconnection grid. These “peaker” plants burn oil or gas, are inefficient, and often sit in disadvantaged communities, raising environmental justice concerns about pollution and health impacts. Reuters

Critics argue that leaning too heavily on legacy technologies—whether fossil fuels or military reactors—could undermine clean energy goals and slow the transition to a sustainable grid. While nuclear solutions offer low-carbon power, they come with their own political and economic debates, particularly about waste management and long-term costs.

Industry and Government Perspectives

Industry leaders are vocal about the dual nature of AI’s energy challenge: it is both a risk and an opportunity. A survey of energy executives by Honeywell found that the vast majority believe AI could enhance energy security by optimizing grid operations, predictive maintenance, and operational efficiency—even as demand grows. Nearly 81% of respondents expect AI to become “critical” in energy systems within the next five years. Honeywell

Government agencies are also adapting. In recent months, the U.S. Department of Defense has narrowed its technology focus to key areas including AI, recognizing its importance for national security. Meanwhile, other branches of government are exploring public-private partnerships to accelerate energy infrastructure that can support both defense and civilian AI applications.

What Comes Next?

As AI expands, the urgency to solve its energy needs will only increase. Analysts warn that roughly 40% of existing AI data centers worldwide could face operational limits by 2027 if power availability doesn’t keep pace with growth. Data Center Dynamics

Rather than viewing military energy resources as a stopgap, some experts argue they could be a bridge to a more robust and resilient national energy framework. Combining military expertise with innovation in nuclear, renewable, and smart grid technologies might offer a multifaceted solution that satisfies capacity, reliability, and sustainability goals.

In the end, the AI revolution isn’t just about algorithms and silicon chips—it’s about powering the infrastructure that makes them possible. As the U.S. explores unlikely energy partners in the military, the stakes are clear: how America fuels its AI future may determine its economic and strategic leadership for decades to come.
