AI data centers "eat" electricity, and Google (GOOGL.US) is also seeking to shift to nuclear power.

Google (GOOGL.US) is working with utility companies in the US and other countries to assess the potential of nuclear power as a possible energy source for its data centers, highlighting the company's growing interest in using nuclear power to fuel the artificial intelligence boom.

Alphabet's global head of data center energy Amanda Peterson Corio said: "In the US, in a highly regulated market, we don't have the opportunity to buy power directly, so we're working with our utility partners and the plant to explore how to bring these new technologies — nuclear may be one of them — into the grid."

Other tech giants including Microsoft (MSFT.US) and Amazon (AMZN.US) have also bet on nuclear power, seeing it as a stable, low-carbon energy source that can meet their data centers' surging electricity needs while reducing reliance on fossil fuels and emissions. Microsoft has agreed to buy power from Pennsylvania's Three Mile Island nuclear plant, which has been closed, while Amazon recently bought a nuclear-powered data center in Pennsylvania.

For Google, "having a reliable, always-on energy source is critical as we think about long-term growth," Corio said.
