Big Tech's energy needs mean nuclear power is getting a fresh look from electricity providers

NEW YORK (AP) — Nuclear power is garnering renewed attention amid growing demand for power and cleaner energy.

The power source has seen a resurgence as nations focus on reducing emissions in an effort to combat climate change. At the same time, the technology sector's energy needs are growing in the form of data centers and powerful advances in artificial intelligence.

Those factors have prompted companies and governments to look more closely at a power source whose potential hazards made it unpopular only a few decades ago. The U.S. is the fastest growing market for data centers, according to McKinsey, which forecasts demand to more than triple by 2030 to 80 gigawatts.

Constellation Energy plans on reopening Three Mile Island in Pennsylvania under a deal with Microsoft. Oracle plans to use new technology in the form of small modular nuclear reactors to power its data centers, while Google is purchasing nuclear energy from small modular reactors in development by Kairos Power. Amazon bought a data center powered by nuclear energy in Pennsylvania earlier this year and is also investing in small nuclear reactors.
