Electricity is becoming what oil was in the 20th century: the resource that will define global power and economic dominance for the next two decades. As artificial intelligence workloads consume energy at unprecedented scales, the companies and countries that control clean, large-scale power capacity are positioning themselves to dictate terms to the entire AI economy. This is not a gradual shift; it is a resource war already underway, and the stakes have never been higher.

A single ChatGPT query consumes roughly 10 times the energy of a Google search. Training next-generation large language models requires power equivalent to small cities. Goldman Sachs Research projects that global data center power demand will surge up to 165 percent by 2030 compared to 2023 levels, while the Electric Power Research Institute forecasts that data centers could increase their share of U.S. power consumption from roughly 5 percent today to as high as 17 percent by 2030. The world simply does not have enough clean, reliable, large-scale electricity to meet these demands, and the timeline to build new generation capacity runs ten to fifteen years at minimum.

Why Are Tech Giants Suddenly Obsessed With Nuclear Power?

The hyperscalers have looked at the grid, examined their AI roadmaps, and concluded that the gap between what they need and what utilities can deliver is unbridgeable on any reasonable timeline. Microsoft signed a 20-year deal to restart the Three Mile Island nuclear plant in Pennsylvania, a facility offline since 2019, specifically to power AI workloads. Amazon paid $650 million for a single data center campus co-located with the Susquehanna nuclear station. Google announced agreements with Kairos Power for small modular reactors, or SMRs. Meta issued a request for proposals seeking up to 4 gigawatts of new nuclear capacity.

These are not casual investments. These are companies committing billions of dollars to lock in clean electricity ten and twenty years in advance, not because power markets are functioning well, but because they have concluded that without long-term secured power, their entire AI strategies may collapse.

The Trump administration is backing this nuclear push with substantial government support. The administration announced more than $80 billion in commitments to support construction of reactors designed by Westinghouse Electric, including the AP1000 model previously used in the Vogtle project in Georgia. The administration also signed an executive order requiring the Nuclear Regulatory Commission to compress approval cycles for new construction and operating licenses to 18 months, half the previously required time.

What Are Small Modular Reactors and Why Do They Matter for AI?

Small modular reactors represent the core vehicle of the nuclear revival, though their commercial prospects remain full of uncertainties. Unlike traditional large reactors with capacities typically exceeding 1,000 megawatts, individual SMRs generally have capacities no greater than 300 megawatts and can be deployed individually or in clusters, offering greater flexibility.

In Idaho, community forums have highlighted the practical advantages of SMRs for rural energy independence. A typical SMR unit occupies roughly 50 acres, compared with thousands of acres that solar developers have proposed for comparable power output in the same region. One local solar plan called for as much as 4,000 acres on Bureau of Land Management land. SMR units can often be built in clusters on a shared industrial space, expanding capacity as demand grows. Fuel pellets roughly a half-inch in diameter are designed to power the equivalent of about 1,800 homes for 80 to 90 years, with far less frequent maintenance than conventional nuclear reactors, whose fuel rods are typically serviced every eight to nine months.

"Nuclear energy is a natural fit for Idaho because it builds on the state's long history of leadership in clean, reliable energy and advanced nuclear innovation. For Bannock County, it can mean high-quality jobs, stronger partnerships with Idaho State University and local industry, new workforce opportunities, and long-term economic growth for communities across the region," said Jess Gehin, associate laboratory director for Nuclear Science and Technology at the Idaho National Laboratory.

Proponents argue that SMRs employ passive safety designs, with some models using molten salt or liquid metals instead of water as coolant, relying on gravity and other natural processes to prevent overheating, reducing dependence on electric pumps and manual intervention. In construction mode, SMRs are designed for factory prefabrication and on-site assembly. Theoretically, standardized production can reduce construction time and leverage scale effects to lower costs, potentially avoiding the common schedule delays and cost overruns seen in traditional nuclear projects.

How to Evaluate SMR Viability for Your Region

• Land Footprint Comparison: SMRs require roughly 50 acres per unit compared with thousands of acres for equivalent solar capacity, making them viable for areas with limited available land or strong environmental protections.
• Cost Structure Analysis: Nuclear construction costs work out to roughly 60 cents per kilowatt-hour compared with about 40 cents for solar, but once operational, nuclear facilities produce power more cheaply than solar, coal, or other sources since fuel and maintenance costs remain low for decades.
• Timeline Expectations: Construction timelines for a single SMR are estimated at roughly three to five years, though potential complications and delays can often stymie completion dates. Industry expectations are that the earliest SMRs will come online in the early 2030s.
• Water Requirements: Cooling methods vary by design. Some reactors use water, others air, and some use a combination of the two, while others rely on closed-loop liquid metal systems. Smaller reactors generally require significantly less water than conventional nuclear plants.

Who Is Winning the Global Power War?

The battle for AI-grade power is being fought on four distinct fronts, each reshaping the global economy in real time.

In the United States, hyperscalers are scrambling to lock in nuclear capacity. But the harder front, the one that gets less attention but matters more strategically, is what is happening across the Atlantic. While U.S. hyperscalers chase nuclear plants, European jurisdictions with the best AI power profiles in the world are quietly ensuring their capacity stays in domestic hands.

Norway, Finland, and Sweden sit on top of massive hydroelectric and nuclear generation, in cold climates that slash cooling costs, with stable governments and EU data sovereignty protections built in. For AI workloads, the combination is close to perfect. But it is closing fast. Norway has effectively capped new data center operators at just 5 megawatts of initial allocation, barely enough to run a small Bitcoin mining operation, let alone an AI training cluster. Finland and Sweden are tightening as well, prioritizing existing operators and domestic strategic interests over hyperscalers showing up with billions of dollars to spend.

European governments have looked at the U.S. experience, watched American utilities sell capacity to whoever pays the most, and decided they will not let that happen on their soil. The power that already exists today in the Nordic markets that matter is largely the capacity that will exist five years from now. The companies that locked in significant Nordic power before the surge are sitting on something that cannot be replicated, no matter how much capital is thrown at it.

A third front is opening that very few American investors are watching carefully. The Gulf states, sitting on sovereign wealth that runs into the trillions, have looked at the AI power race and decided they want a position in it. The UAE, in particular, has been moving aggressively. Phoenix Group, the publicly-listed Bitcoin miner ranked tenth globally by market capitalization and based in Abu Dhabi, holds a 20.8 percent equity stake in Bitzero Holdings and a board seat. That is sovereign Gulf money taking a long position in Nordic power infrastructure that hosts AI workloads, and it is a pattern likely to repeat across other AI-power assets globally.

The fourth front is the most isolated and the hardest to assess from the outside. China has watched the global scramble for AI-grade power and concluded that it needs to build its own self-sufficient ecosystem, walled off from Western supply chains and Western capacity constraints.

Public acceptance of nuclear energy is rising again in the United States. According to a Pew Research Center survey, in 2025, 59 percent of American adults support expansion of nuclear energy use, a significant jump from 43 percent a decade ago. In Idaho, a countywide survey drew more than 700 responses, nearly 90 percent of which showed a positive view of nuclear energy, suggesting that rural communities are increasingly open to hosting SMR facilities if they bring local jobs and economic benefits.

The nuclear industry faces profound structural challenges before SMRs can scale. From regulatory approval to fuel supply, from engineering construction to talent reserves, obstacles remain substantial. Currently, among dozens of SMR projects under development in the United States, only a few have received regulatory approval. NuScale Power has obtained Nuclear Regulatory Commission design certification, and TerraPower, supported by Bill Gates, has obtained a construction permit in Wyoming for a commercial reactor. However, no SMR company has yet received a formal operating license.

The companies that control electricity in the next decade may dictate terms to the rest of the AI economy for the next two decades. The countries that hold it are about to find themselves with strategic leverage they have not enjoyed in a century. And the small handful of players who locked in AI-grade power capacity before the surge may soon look very different from what they do today. The power war is not coming; it is already here.
