AI goes nuclear

When Microsoft bought a 407-acre pumpkin farm in Mount Pleasant, Wisconsin, it wasn’t to grow Halloween jack-o’-lanterns. Microsoft is growing data centers—networked computer servers that store, retrieve, and process information. And those data centers have a growing appetite for electricity.

Microsoft paid a whopping $76 million for the pumpkin farm, which was assessed at a value of about $600,000. The company, which has since bought other nearby properties to expand its footprint to two square miles, says it will spend $3.3 billion to build its 2-million-square-foot Wisconsin data center and equip it with the specialized computer processors used for artificial intelligence (AI).

Microsoft and OpenAI, maker of the ChatGPT bot, have talked about building a linked network of five data centers—the Wisconsin facility plus four others in California, Texas, Virginia, and Brazil. Together they would constitute a massive supercomputer, dubbed Stargate, that could ultimately cost more than $100 billion and require five gigawatts of electricity, or the equivalent of the output of five average-size nuclear power plants.
