Big Tech’s Binding Pact with Nuclear Energy: Powering AI’s Future
In the collective memory of many, nuclear energy may evoke dystopian scenarios—a toxic melange of power plant failures, radioactive waste, and protests. This negative image, largely stemming from the catastrophic incidents at Three Mile Island in the U.S. and Chernobyl in the former Soviet Union during the late 20th century, has long overshadowed the actual safety record of nuclear energy. Contrary to public perception, nuclear power offers a more reliable and environmentally friendly alternative compared to many traditional energy sources, including fossil fuels.
Fast forward to 2024, and the narrative around nuclear energy is undergoing a seismic shift. Major technology players such as Microsoft, Google, and Amazon are diving headfirst back into the world of nuclear power, largely driven by the burgeoning demands of artificial intelligence (AI).
Tech Giants Commit to Nuclear Power for AI Operations
In recent months, the leading titans of cloud computing have made significant strides in reestablishing ties with nuclear energy. This trend is no coincidence; it comes as they expand their AI capabilities and infrastructure. Notably, key nuclear initiatives have emerged from these firms, underscoring a transformative commitment to powering the next generation of technology.

Google’s Collaboration with Kairos Power: Google has forged a pact with Kairos Power to implement small modular reactors (SMRs) aimed at powering its AI data centers. The project is expected to produce 500 megawatts of clean energy by 2035, contributing to Google’s ambitious target of achieving 24/7 carbon-free energy by 2030.

Microsoft Resurrects Three Mile Island: Microsoft plans to reactivate the Three Mile Island plant in Pennsylvania by 2028 through a collaboration with Constellation Energy, generating 835 megawatts of power for its growing AI data demands. The tech giant is also exploring fusion energy through a partnership with Helion Energy in a bid to secure future energy sources.
- Amazon’s Nuclear Ventures: In a strategic move, Amazon announced three agreements on October 16, 2024, aimed at nuclear energy development via SMRs. Working with Energy Northwest in Washington State, the company plans to develop four SMRs to eventually generate up to 960 megawatts by the 2030s. Amazon is also looking into additional partnerships to meet regional energy needs.
These SMRs are versatile and designed with safety in mind, offering a maximum output of 300 MWe while being scalable, modular, and more efficient than traditional nuclear facilities.
Unpacking the Motivation Behind This Shift to Nuclear
The surge in interest from these tech behemoths can be attributed to the insatiable energy demands of AI operations. As data centers increasingly consume vast amounts of electricity, the current reliance on fossil fuel-powered grids poses significant obstacles. Edward Kee, CEO of Nuclear Economics Consulting Group, highlights this dilemma, noting that while tech firms are striving for zero-carbon operations, they face challenges in meeting those goals with intermittent energy sources like wind and solar.
Domestic demand for energy from AI is skyrocketing. Training foundational models, such as OpenAI’s GPT-3, which reportedly required 1,287 megawatt-hours (MWh) for a single training session, emphasizes the need for a stable and clean energy source. According to the International Atomic Energy Agency (IAEA), electricity consumption from data centers is predicted to double by 2026, further increasing the necessity for innovative energy solutions.
Navigating Energy Infrastructure Challenges
Interestingly, while tech companies may seem to have ample opportunities to draw energy from the existing grid, they face scrutiny from local utilities reluctant to commit large amounts of energy to new data centers. This has led these companies to explore nuclear energy as a reliable alternative.
As Kee explains, tech giants are expected to provide comprehensive plans to ensure that their energy demands can be met without overburdening local power infrastructures. This is where the integration of nuclear energy comes into play, offering a stable and substantial power supply that could alleviate potential grid strain.
The Strategic Advantages of Proximity
While it may seem feasible for tech firms to source energy from distant nuclear plants, there’s a compelling case for situating data centers adjacent to these facilities. The high energy demands of AI operations necessitate a reliable supply that can be delivered without incurring expensive infrastructure upgrades for energy transmission.
Implications for the Future
The sudden shift back to nuclear power by tech companies represents more than just a temporary trend; it indicates a holistic approach to energy that aligns with climate goals. Companies like Amazon, Google, and Microsoft are not only changing their energy narratives but potentially paving the way for a broader acceptance of nuclear energy as a legitimate player in the clean energy sector.
While the journey towards revitalizing nuclear power is bound to face regulatory challenges, Kee remains optimistic about the long-term outlook. The alignment of advanced technologies with energy demands could herald a new era of investment in nuclear energy, ultimately contributing to a more sustainable future.
In conclusion, if AI catalyzes a renewed embrace of nuclear power, it may very well signify the dawn of a nuclear energy renaissance—one that could transform not just tech operations but the global approach to energy consumption and climate responsibility.
