The cloud computing and retail giant signed a deal to buy electricity generated by small modular nuclear reactors. Put Amazon on the list of big technology firms embracing new nuclear technologies to fuel their data centers.

Each deal supports the development of small modular reactors (SMRs), which can be one-tenth to one-quarter the size of a traditional nuclear power plant. If these projects make it to the finish line, SMRs would be a source of carbon pollution-free energy for big tech companies trying to salvage their climate goals by turning to nuclear energy.

Amazon has a deal with Energy Northwest to fund the initial feasibility phase of a nuclear facility in central Washington, with the right to purchase electricity from the 320 megawatt plant.
