As climate change accelerates, the need for clean energy solutions is more pressing than ever. For years, renewable energy sources such as wind and solar have been at the forefront of the climate debate. But as energy-intensive industries like artificial intelligence (AI) continue to expand, these renewables alone are struggling to meet demand. This is where nuclear power, often sidelined due to its controversial history, is making a surprise comeback, especially among tech giants like Microsoft and Amazon.
AI and energy: demand is growing
Artificial intelligence, with its complex algorithms and massive data centers, requires a constant, reliable power supply. Traditional renewable energy sources such as wind and solar, while clean, are intermittent. They cannot sustainably provide the 24/7 power required for these data centers. To fill this gap, nuclear power is emerging as a viable alternative.
For a detailed look at the potential role of nuclear power in the energy future, see this comprehensive report from the International Atomic Energy Agency (IAEA).
Microsoft, for example, agreed to buy electricity from the Three Mile Island nuclear power plant in Pennsylvania, infamous for a partial accident in 1979. The factory, which was closed in 2019, is being rebuilt because Microsoft needs a huge amount of energy. for the operation of its data centers. By using nuclear power, the company can meet its energy needs without relying on fossil fuels, in line with its ambitious climate goals.
Why nuclear energy?
Unlike coal or gas, nuclear power does not emit carbon during operation. As the world moves towards carbon neutrality, nuclear power provides a solution that balances environmental and industrial needs.
The US government has also stepped in to support the revival of nuclear power. Congress approved tax breaks to support existing nuclear reactors. States such as California have reversed decisions to close factories, and in Michigan, Holtec International aims to reopen a plant that closed in 2022.
Problems of restoration of nuclear reactors
Reopening a nuclear power plant is not an easy task. Reactors like those at Three Mile Island are in need of major renovations after years of inactivity. This includes replacing power transformers, repairing cooling systems and ensuring there is no corrosion. Despite these problems, companies like Constellation Energy are spending billions to keep these reactors running safely.
The involvement of technology companies such as Microsoft has given new life to the nuclear sector. With contracts that guarantee long-term power purchases, these tech giants are providing the economic stability needed to restore the viability of nuclear power projects.
A new era for nuclear energy
This growing interest in nuclear power is indicative of a change in the industry's approach to energy solutions. Technology companies, in particular, are eager to use nuclear power because it offers a reliable and scalable way to power their growing infrastructure without exacerbating climate change.
Although nuclear power still carries risks, advances in technology and stricter regulations make today's reactors safer than ever before. For companies like Microsoft, Amazon, and others, the benefits of nuclear power — constant power and zero carbon emissions — outweigh the risks, positioning nuclear power as a cornerstone of their energy strategies.
The future of energy
As nuclear power re-enters the conversation, the question is: Will more industries follow the example of the tech giants? With the global push for sustainable energy solutions, nuclear power can become a key player in the energy balance of the future, helping to combat climate change while driving the digital age.
