Tech giants Amazon and Google are investing in the next generation of nuclear reactors. Both companies are seeking new sources of carbon-free electricity to meet increasing demand from data centers and artificial intelligence.

E-commerce giant Amazon joins Google and other tech companies in investing in nuclear power they plan to use in the race to build new AI-powered products.

Amazon’s agreement with Washington-based Energy Northwest will produce four advanced SMRs that will be built, owned, and operated by the utilities consortium. The tech giant is also investing in SMR reactors and fuel developer X-energy, it said. X-energy’s design for advanced nuclear reactors will be used for Amazon’s project with Energy Northwest.
