Amazon and Google back global push to triple nuclear energy capacity by 2050

Amazon and Google have pledged their support for a global initiative to triple nuclear energy capacity by 2050, marking a significant step in the push for clean energy. The announcement, made on Wednesday at the CERAWeek conference in Houston, also saw the involvement of shale company Occidental Petroleum and Japanese machinery maker IHI Corp.

This commitment is part of a broader effort to address climate change by increasing reliance on nuclear energy, which currently generates about 9% of the world’s electricity through 439 reactors. The World Nuclear Association (WNA), which facilitated the pledge, expects additional support from industries such as maritime, aviation, and oil and gas in the coming months.

The pledge builds on a similar commitment made by over 30 countries in 2023, which also aimed to triple nuclear capacity by 2050. The move is seen as essential in tackling global carbon emissions and ensuring a stable, low-carbon energy future.

While nuclear energy currently provides 9% of the world’s electricity, it faces challenges due to the declining number of operational reactors. As of early 2025, there are approximately 411 nuclear power reactors globally, with a combined capacity of 371 gigawatts.

In addition to their pledge, Amazon’s cloud business plans to invest $8.2 billion in infrastructure projects in India, further strengthening its commitment to sustainable energy solutions.
