Why Nuclear Energy Is Back in the Power Conversation

For years, discussions about the future of energy have focused primarily on renewables like wind and solar. Today, nuclear power generation is finding its way back into the conversation. The International Energy Agency (IEA) reported that 78 GW of nuclear capacity was under construction worldwide in 2025, one of the highest levels seen in the last three decades.

What’s driving this renewed interest? Rising electricity demand, growing AI infrastructure, increased electrification, and the need for reliable power are prompting energy leaders to rethink how future energy systems will be built. Nuclear energy is not a silver bullet, nor is it replacing other generation sources. But it is increasingly being viewed as an important part of the solution.

Let’s take a closer look at why.

How Nuclear Energy Works

At its core, nuclear power generation has remained remarkably consistent for decades. Inside a nuclear reactor, atoms are split through a process called nuclear fission. The energy released creates heat, which converts water into steam. That steam spins a turbine connected to a generator that produces electricity.

The technology itself isn’t new. What has changed is the context surrounding it. As energy demand grows and utilities seek reliable sources of electricity that can operate around the clock, many organizations are taking another look at the role nuclear power can play within a modern energy portfolio.

Why Nuclear Energy Is Relevant Again

The biggest reason nuclear is back in the spotlight is simple: the world needs more electricity.

After more than a decade of relatively flat electricity consumption, demand is growing again. The U.S. Energy Information Administration (EIA) reported in their 2026 Annual Energy Outlook that U.S. electricity demand increased by an average of 2.1% annually over the last five years. At the same time, utilities must support growing populations, electrification initiatives, domestic manufacturing expansion, and increasingly energy-intensive technologies.

AI is adding another layer of complexity. Data centers require enormous amounts of power and must operate continuously. Across the energy industry, leaders are looking for generation sources that can provide dependable electricity regardless of weather conditions or time of day.

Nuclear’s appeal lies in its ability to deliver large amounts of steady power. While solar, wind, battery storage, hydropower, and natural gas all have important roles to play, nuclear offers a source of carbon-free electricity generation that can operate continuously for extended periods. That reliability is becoming increasingly valuable as grids become more complex.

The trend is reflected globally. Low-emissions energy sources—including renewables and nuclear—are expected to account for 50% of global electricity generation by 2030, up from 42% in 2025.

Who’s Investing in Nuclear Energy?

One of the clearest signs of nuclear’s resurgence is who’s backing it. Some of today’s most significant investments are coming from organizations better known for technology than traditional energy production.

Microsoft: Microsoft announced in 2024 an agreement with Constellation Energy to support the restart of Pennsylvania’s Three Mile Island Unit 1, renamed the Crane Clean Energy Center. The facility is expected to provide 835 MW of carbon-free electricity to the PJM grid.
Google: Google partnered with Kairos Power in 2024 to purchase power from multiple small modular reactors (SMRs), with the first reactor targeted for deployment around 2030 and additional deployments planned through 2035. The agreement could ultimately provide up to 500 MW of carbon-free power.
Amazon: In 2024, Amazon announced agreements with X-energy and Energy Northwest supporting advanced SMR development, including a planned 320 MW project in Washington state with the potential to expand to 960 MW.
Meta: Meta announced in early 2026 agreements with Vistra, TerraPower, and Oklo that are expected to support up to 6.6 GW of new and existing clean energy by 2035, including support for operating nuclear plants and the development of advanced nuclear technologies.

Nearly two years after many of the first major corporate nuclear announcements were made, companies are moving beyond commitments and into permitting, construction, reactor demonstrations, and plant restarts. That progress suggests nuclear is becoming an active component of long-term power planning, as organizations look to secure reliable electricity for future growth and increasingly view nuclear as part of their broader energy strategy.

The Future of Nuclear Energy and the Industries It Affects

In the near term, much of the progress may come from extending the life of existing plants, increasing output from operating facilities, restarting retired assets, and advancing select new reactor projects. The U.S. Department of Energy has launched initiatives aimed at accelerating advanced reactor development and expanding nuclear generation capacity in the years ahead, like the Reactor Pilot Program.

SMRs will continue to attract attention, but most industry observers expect deployment to occur gradually rather than all at once. Additional SMR projects are likely to begin construction in countries including the United States, Canada, South Korea, and the United Kingdom.

As nuclear power generation investments grow, the impact will extend beyond utilities. Data centers, advanced manufacturing facilities, telecommunications infrastructure, and industrial operations all stand to benefit from increased access to reliable electricity. The demand for engineers, project managers, skilled trades professionals, cybersecurity experts, operations specialists, and energy consultants is also expected to grow as infrastructure projects move from planning to execution.

The success of these projects will depend on organizations’ ability to attract, develop, and retain highly specialized talent. From licensing and construction to operations and maintenance, workforce readiness will play a critical role in determining how quickly new nuclear capacity can move from concept to reality.

Building the Teams Behind the Next Energy Era

Nuclear energy isn’t the only answer to rising power demand, but it is becoming an increasingly important part of the conversation. As organizations plan for a future shaped by AI, electrification, infrastructure modernization, and evolving sustainability goals, reliable power generation will remain a strategic priority. The true challenge has become having the people, technology, and execution capabilities to turn energy strategy into reality.
