While Seattle-based Amazon is best known for its dominant position as an online retailer, the company has been in the cloud computing space since 2006 with Amazon Web Services, a subdivision that has since become a leader in its category. It is reportedly generating around 17% of Amazon’s overall revenue, which hit $575 billion last year.

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.

Amazon is the latest Big Tech firm to ink deals for nuclear power, following Google and Microsoft, as artificial intelligence drives a need for more energy.
