Why Big Tech is turning to nuclear to power its energy-intensive AI ambitions
The tech industry’s nuclear power adoption is gaining momentum as companies scramble to meet the escalating energy demands of artificial intelligence (AI) and associated data centers. The rising need for reliable, low-carbon energy sources has placed nuclear energy for AI at the forefront of this strategic shift.
Notably, Google’s landmark partnership with nuclear startup Kairos Power is expected to add over 500 megawatts of new 24/7 carbon-free power to the US electricity grid within the next decade. The deal involves purchasing energy from seven small modular nuclear reactors (SMRs), with the first operational units anticipated by 2030 and full completion by 2035. This move aligns with Google’s ambition to achieve net-zero carbon emissions by 2030, balancing variable renewable energy sources with nuclear energy for sustainable AI development.
Microsoft is also making significant strides in nuclear energy for AI. The tech giant has partnered with Constellation to revive a dormant reactor at the Three Mile Island nuclear power plant in Pennsylvania. Similarly, Amazon has invested $500 million with Dominion Energy to explore building a small modular reactor near the North Anna nuclear power station.
Tech leaders like Michael Terrell from Google emphasize the critical need for clean, dependable energy that nuclear power provides. The sentiment is echoed by OpenAI CEO Sam Altman, who is actively involved in conventional and fusion nuclear power initiatives. These leaders recognize that the current massive reliance on nonrenewable sources has caused major tech companies to miss crucial climate targets. Hence, the shift to nuclear energy is seen as a pragmatic solution to ensure future AI development adheres to environmental goals.
The International Energy Agency underscores the urgency of this transition, projecting that global electricity consumption from data centers, AI, and cryptocurrencies will more than double from 460 terawatt-hours in 2022 to over 1,000 TWh by 2026. Furthermore, nuclear reactors in the U.S. boast a capacity factor exceeding 92%, far outstripping the 25–35% capacity factor of wind and solar power.
Google’s data centers alone consumed an estimated 12.4 terawatt-hours of electricity in 2021. Such substantial energy usage necessitates a robust, sustainable supply, something nuclear energy for AI promises to fulfill. The U.S. Department of Energy’s $303 million grant to Kairos Power for its Hermes demonstration reactor, scheduled to be operational by 2027, further validates the critical role of nuclear power in the tech industry’s future.
| Company | Partnership | Energy Initiative | Timeline |
|---|---|---|---|
| Kairos Power | 500 MW from 7 SMRs | First reactor by 2030, completion by 2035 | |
| Microsoft | Constellation | Revitalize Three Mile Island | Ongoing |
| Amazon | Dominion Energy | Small modular reactor near North Anna | In exploration phase |
The drive towards the tech industry’s nuclear power adoption signifies a profound commitment to sustainable, reliable energy, ensuring that AI innovations can continue to advance sustainably.
Google’s Investment in Kairos Power
Google has taken a significant step forward in securing a sustainable energy future by partnering with Kairos Power to develop small modular reactors (SMRs). This collaboration is a landmark initiative under the Google nuclear energy initiative, aiming to bolster AI-driven data centers with reliable, clean power.
Details of the Deal
In a transformative agreement, Google plans to secure up to 500 megawatts (MW) of carbon-free power by 2035 through its deal with Kairos Power. These advanced Kairos Power modular reactors are set to be activated between 2030 and 2035, aligning with Google’s timeline for scaling its AI capabilities. The small footprint of SMRs makes them ideal for tech companies needing concentrated and efficient energy sources for their data-intensive operations.
Projected Impact on AI Development
The investment stands as a strategic maneuver by Google to future-proof its AI infrastructure. As AI technologies proliferate, demanding massive computational power, the Google nuclear energy initiative comes at a crucial time. Kairos Power projects that its SMRs could contribute up to 200 gigawatts (GW) of advanced nuclear capacity by 2050, providing a substantial economic impact according to the U.S. Department of Energy. This aligns perfectly with why big tech is turning to nuclear power to address energy deficits and meet burgeoning AI energy needs.
