Corporate powerhouses join pledge to triple nuclear energy by 2050

The World Nuclear Association announced that Amazon, Dow, Google, Meta, and a dozen more corporations signed the “Large Energy Users Pledge.” It is the first time major businesses outside of the nuclear sector have partnered to publicly back a major expansion of nuclear power to help meet global energy demand, according to the WNA. The signatories, which are joining 14 global banks in support, are advocating for equal access worldwide to finance nuclear energy projects.

The announcement was made during CERAWeek 2025, a global energy conference being held in Houston, Texas, this week, that includes representatives from 80 countries and hundreds of corporate executives. CERAWeek offers corporate leaders and policymakers a chance to learn about and discuss strategic energy plans. The theme of this year’s event is “Moving Ahead: Energy Strategies for a Complex World.”

“The unprecedented support announced today by some of the world’s most influential companies to at least triple global nuclear capacity by 2050 sends a clear signal to accelerate policy, finance and regulatory changes that enable the rapid expansion of nuclear power,” said Sama Bilbao y Leon, director general of the WNA, in the news release. “The global shift toward more nuclear highlights this is the only way we’ll deliver the abundant firm clean energy required to power growth and innovation in technology, a host of other industries and the entire economy.”

Background: The pledge to triple nuclear capacity by 2050 was a call to action at the COP28 global climate conference held in Dubai in 2023. The United States joined more than 20 countries in the initial effort, and support has since grown.

Now, 31 countries and more than 140 nuclear industry companies have signed on to the effort.

The full list of companies that have signed the Large Energy Users Pledge includes Allseas, Amazon, Bureau Veritas, Carbon3Energy, Clean Energy Buyers Alliance, Confederation of Industry of Czech Republic, Core Power, Dow, Federation of Electric Power Companies of Japan, Fly Green Alliance, Google, IHI Corporation, Lloyd's Register, Meta, Occidental, OSGE, and Siemens Energy (which issued a statement of support).

More corporations are expected to sign on to the pledge in the coming months, representing growing interest in nuclear power from industries across the aviation, chemical, maritime, and oil and gas sectors, according to the WNA release.

Driving demand: A report released in February by the International Energy Agency forecasts soaring electricity demand through 2027, driven largely by a growing demand for energy-hungry sources ranging from air conditioners to data centers.

The jump in worldwide electricity demand expected in the next few years is the equivalent of adding Japan’s total annual energy consumption to the global energy use total each year. In the U.S., the world’s second-largest electricity consumer after China, demand is expected to grow by 2 percent annually.

The IEA reports that nuclear energy totals will reach a new high in 2025, fueled largely by the recovery in France’s nuclear power output, restarts in Japan, and new reactors starting operations in China, India, Korea, and other countries.

Statements on the corporate pledge:

• “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.” —Lucia Tian, Google’s head of clean energy and decarbonization technologies
• “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 $1 billion over the last year in nuclear energy projects and technologies, which is part of our broader Climate Pledge commitment to be net-zero carbon by 2040.” —Brandon Oyer, Amazon Web Services’ head of Americas energy and water
• “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.” —Urvi Parekh, Meta’s head of global energy
