• Major tech companies are investing in nuclear power to support AI data centers.
• Nuclear energy provides clean, constant power for data centers.

Tech companies are turning to nuclear power to advance their AI ambitions.

From Amazon to Google, companies at the forefront of the AI boom are investing in nuclear energy to fuel data centers — which provide the infrastructure and resources needed to train and run AI models.

Aside from generating enormous amounts of power, nuclear power is also an attractive choice for companies hoping to meet global net zero goals.

"Companies committed to strong climate goals must ensure their future energy needs are met with clean, carbon-free sources. Nuclear energy, with its unmatched ability to deliver 24/7 power, fits the bill perfectly," Kathryn Huff, an associate professor of nuclear, plasma, and radiological engineering at the University of Illinois Urbana-Champaign and the former assistant secretary for nuclear energy at the Department of Energy, told Business Insider by email.

Here's a closer look at how tech companies are investing in nuclear energy.
