At CERAWeek 2025 in Houston, Texas, a coalition of major energy-consuming companies—Amazon, Google, Meta, Dow, Occidental, Allseas, and OSGE—announced their support for tripling global nuclear capacity by 2050. This commitment, known as the Large Energy Users Pledge, follows similar pledges made by 31 countries, 140 nuclear industry companies, and 14 major global banks and financial institutions in recent years. CERAWeek is an annual conference that brings together energy leaders, policymakers and innovators to discuss the future of energy.
The Importance of the Pledge
The pledge acknowledges that energy demand is expected to rise significantly due to economic growth, even with ongoing efficiency and optimization efforts. The signatories agree that nuclear energy must at least triple by 2050 to support global energy resiliency, security, and the need for a constant supply of clean energy.
Large energy users depend on stable and abundant energy sources to maintain competitive costs, and nuclear power offers a unique advantage—round-the-clock energy generation that is independent of weather conditions. Additionally, nuclear energy plays a crucial role in diversifying the energy grid and ensuring its reliability.
Beyond electricity generation, nuclear technology has a wide range of applications, including:
- Industrial process heat for manufacturing
- Hydrogen production to support clean fuel alternatives
- District heating for urban areas
- Synthetic fuel production for transportation and other industries
The pledge also highlights the need for equal access to financing for nuclear and other energy sources to enable large-scale deployment worldwide.
Industry Leaders Speak on the Commitment
Several executives from the signatory companies emphasized the significance of nuclear energy in their sustainability strategies:
- Lucia Tian, Head of Clean Energy & Decarbonization Technologies at Google, stated:
“We are proud to sign a pledge in support of tripling nuclear capacity by 2050, as nuclear power will be pivotal in building a reliable, secure, and sustainable energy future. Google will continue to work alongside our partners to accelerate the commercialization of advanced nuclear technologies that can provide the around-the-clock clean energy necessary to meet growing electricity demand around the world.”
- Brandon Oyer, Head of Americas Energy and Water at Amazon Web Services, said:
“Accelerating nuclear energy development will be critical to strengthening our nation’s security, meeting future energy demands, and addressing climate change. Amazon supports the World Nuclear Association’s pledge and is proud to have invested more than USD 1 billion over the last year in nuclear energy projects and technologies, as part of our broader Climate Pledge commitment to be net-zero carbon by 2040.”
- Urvi Parekh, Head of Global Energy at Meta, emphasized:
“As global economies expand, the need for a reliable, clean, and resilient energy supply is paramount. Nuclear energy, with its ability to provide continuous power, can help meet this rising demand. We’re excited to join alongside this multi-organizational effort with the Tripling Nuclear Pledge to reiterate our commitment to nuclear energy.”
Growing Corporate Interest in Nuclear Energy
Over the past year, a rising number of companies with large energy demands have begun investing in nuclear power to meet their growing needs while also cutting carbon emissions. The increasing energy consumption of AI infrastructure and data centers has driven interest in small modular reactors (SMRs) and even large-scale nuclear power plants. Additionally, other industries are recognizing the potential of nuclear-generated energy and heat to decarbonize industrial processes.
The pledge was first launched by the World Nuclear Association in partnership with the Emirates Nuclear Energy Corporation ahead of COP28 (28th United Nations Climate Change Conference) in Dubai in 2023.
The Global Energy Outlook
Currently, nuclear power accounts for approximately 9% of global electricity production, with 439 operable reactors worldwide. However, energy demand is expected to grow at around 4% per year, according to the International Energy Agency (IEA). With this anticipated rise, the need for scalable, clean, and reliable energy sources has become more urgent than ever.
The official unveiling of the Large Energy Users Pledge will take place during a special CERAWeek event hosted by the World Nuclear Association and Urenoc on Wednesday evening. This pledge marks a significant step toward ensuring that nuclear energy plays a leading role in powering the future—sustainably, securely, and affordably.
