The unexpected revival of nuclear energy
For decades, nuclear energy has been a polarising topic, once a symbol of a clean, futuristic world, and later a scapegoat for environmental disasters and high costs. However, nuclear energy is now making a surprising comeback, not through government mandates or think tanks, but through the world’s largest tech corporations.
Amazon, Google, and Meta have recently pledged to triple global nuclear power capacity by 2050. This marks one of the most significant private-sector endorsements of nuclear energy in history. This seismic shift in energy strategy raises critical questions: Why nuclear, why now, and what does this mean for the global energy transition?
As the world accelerates towards net-zero targets, nuclear energy is emerging from the shadows, not as a relic of the past but as a necessary solution for the future.
The energy dilemma: Why tech giants are betting on nuclear
Big Tech has an ever-growing demand for energy. Data centres alone are projected to consume 8% of global electricity by 2030, driven by the rise of artificial intelligence, cloud computing, and digital expansion. With sustainability commitments in place, tech companies are at a crossroads:
• Renewables are insufficient: Wind and solar, while critical, are intermittent, requiring massive storage solutions that are still not cost-effective at scale.
• Fossil fuels are not an option: Companies like Google and Amazon cannot afford to regress into high-carbon energy sources with their aggressive net-zero targets.
• Nuclear offers 24/7 clean energy: Unlike renewable sources, nuclear power provides consistent, zero-carbon electricity, making it an ideal base load for an electrified world.
From opposition to advocacy: How public perception is changing
The perception of nuclear energy has been largely shaped by catastrophic events: Chernobyl, Fukushima, and Three Mile Island, leading to widespread fear and regulatory stagnation. However, recent developments have shifted the conversation:
• Energy security concerns: The European energy crisis triggered by Russia’s invasion of Ukraine has prompted policymakers to reconsider nuclear energy as a solution to energy insecurity
• The rise of Small Modular Reactors (SMRs): SMRs represent a new generation of nuclear technology that is safer, cheaper, and faster to deploy than traditional plants
• Environmental urgency: As the climate emergency intensifies, even the most skeptical environmental groups are acknowledging that nuclear energy could be critical to meeting global decarbonisation goals
The United Nations Intergovernmental Panel on Climate Change (IPCC) now recognises nuclear energy as an essential part of the solution, warning that achieving net-zero without nuclear energy will be significantly more difficult and costly.
The business case: Nuclear as an investment
First opportunity: Corporate Power Purchase Agreements (PPAs) for nuclear
Tech companies have long been major buyers of renewable energy through PPAs, investing in wind and solar farms to secure clean power. The inclusion of nuclear in this model is a game-changer:
• Injection of capital. Amazon, Google, and Meta’s commitment is expected to inject billions into nuclear projects, accelerating commercialisation
• Financial certainty. Corporate PPAs can help mitigate the financial risks associated with nuclear investments, making it a more attractive option for market adoption
• Strategic hedge. Securing reliable energy through nuclear offers tech companies protection against rising electricity prices and energy volatility
2. The race for Small Modular Reactors (SMRs)
Traditional nuclear plants are costly and take over a decade to build. SMRs, however, are changing this equation:
• Modular and scalable: SMRs can be deployed in smaller, distributed grids, making them more adaptable and cost-effective
• Increased safety: SMRs incorporate passive safety features, reducing the risk of catastrophic failures
• Reduced construction time: SMRs can be constructed in factories and assembled on-site, cutting down on time and cost
Leading energy companies, including Bill Gates’ TerraPower, Rolls-Royce, and NuScale Power, are heavily investing in SMRs as the future of nuclear energy.
3. Policy and regulatory tailwinds
Governments are beginning to embrace nuclear energy as a net-zero enabler:
• U.S. Inflation Reduction Act: This initiative provides tax credits for advanced nuclear projects, positioning the U.S. as a leader in next-gen reactors
• EU Green Taxonomy: Nuclear energy is now classified as a “sustainable investment” under the EU Green Taxonomy, unlocking billions in private capital
• Global nuclear expansion: Countries like China, the UAE, and Saudi Arabia are aggressively expanding their nuclear portfolios to meet future energy demands
Challenges & roadblocks: is the nuclear comeback realistic?
Despite the optimism, nuclear energy still faces significant hurdles:
1. High initial costs & financing risks
Nuclear plants remain capital-intensive, requiring billions in upfront investment. Even with SMRs, securing financing for nuclear projects remains a major challenge compared to wind and solar, which have a more established investment ecosystem.
2. Public & political resistance
While attitudes are shifting, nuclear skepticism remains strong. Many governments are wary of potential backlash, and opposition from environmental groups still exists.
3. Waste management & security risks
• Nuclear waste storage remains an unsolved issue, with long-term disposal solutions still under debate
• Geopolitical risks related to uranium supply chains and potential weaponisation of nuclear materials remain a concern
However, emerging solutions, such as recycling spent nuclear fuel and thorium reactors are being explored to address these challenges
Conclusion: Is this the moment nuclear becomes mainstream?
The endorsement of nuclear energy by Amazon, Google, and Meta marks a turning point. While renewables will continue to dominate the clean energy conversation, nuclear is now re-emerging as a critical piece of the puzzle.
For tech companies, the shift is strategic:
• They need uninterrupted, clean power to sustain their data-driven growth
• They see investment potential in next-gen nuclear technologies
• They recognise that a net-zero future without nuclear energy is unlikely
For the broader energy transition, this could be the moment that nuclear energy moves from the sidelines to centre stage. Whether governments and investors seize this opportunity remains to be seen, but one thing is certain: the future of clean energy will not be wind, solar, or nuclear alone—it will be all of them, together.
What is the next phase of the energy revolution? As corporations rethink their sustainability strategies and the world grapples with the realities of net-zero ambitions,
nuclear is no longer just a relic of the past, it’s a contender for the future. Will this momentum be enough to push nuclear into the mainstream, or will old challenges hold it back once again? The answer may shape the trajectory of global energy for decades to come.
