Facing immense electricity needs for AI, tech giants like Amazon are now directly investing in nuclear power, particularly small modular reactors (SMRs). This infusion of venture capital is revitalizing a sector that has historically relied on slow-moving government funding, imbuing it with a Silicon Valley spirit.

The massive electricity demand from AI data centers is creating an urgent need for reliable power. This has caused a surge in demand for natural gas turbines—a market considered dead just years ago—as renewables alone cannot meet the new load.
While solar panels are inexpensive, the total system cost to achieve 100% reliable, 24/7 coverage is massive. These "hidden costs"—enormous battery storage, transmission build-outs, and grid complexity—make the final price of a full solution comparable to nuclear. This is why hyperscalers are actively pursuing nuclear for their data centers.
The massive energy consumption of AI has made tech giants the most powerful force advocating for new power sources. Their commercial pressure is finally overcoming decades of regulatory inertia around nuclear energy, driving rapid development and deployment of new reactor technologies to meet their insatiable demand.
Despite staggering announcements for new AI data centers, a primary limiting factor will be the availability of electrical power. The current growth curve of the power infrastructure cannot support all the announced plans, creating a physical bottleneck that will likely lead to project failures and investment "carnage."
For years, the tech industry criticized Bitcoin's energy use. Now, the massive energy needs of AI training have forced Silicon Valley to prioritize energy abundance over purely "green" initiatives. Companies like Meta are building huge natural gas-powered data centers, a major ideological shift.
The U.S. has the same 1.2 terawatts of power capacity it had in 1985. This stagnation now poses a national security risk, as the country must double its capacity to support AI data centers and reshoring manufacturing. The Department of Energy views solving this as a "Manhattan Project 2.0" level imperative.
To secure the immense, stable power required for AI, tech companies are pursuing plans to co-locate hyperscale data centers with dedicated Small Modular Reactors (SMRs). These "nuclear computation hubs" create a private, reliable baseload power source, making the data center independent of the increasingly strained public electrical grid.
The infrastructure demands of AI have caused an exponential increase in data center scale. Two years ago, a 1-megawatt facility was considered a good size. Today, a large AI data center is a 1-gigawatt facility—a 1000-fold increase. This rapid escalation underscores the immense and expensive capital investment required to power AI.
The primary factor for siting new AI hubs has shifted from network routes and cheap land to the availability of stable, large-scale electricity. This creates "strategic electricity advantages" where regions with reliable grids and generation capacity are becoming the new epicenters for AI infrastructure, regardless of their prior tech hub status.
A large government commitment, like the $80 billion nuclear development plan with Westinghouse, does more than create a single customer. It acts as a powerful catalyst for the entire industry. This de-risks the supply chain, signals market viability, and attracts massive private capital (e.g., Brookfield), creating tailwinds for all players.
