The U.S. Department of Energy has approved a $1.9 billion loan to the owner of an Iowa nuclear power plant that Google previously said it would help bring back online. The plant, which had been shuttered, is being revived in part to supply carbon-free power for the tech giant's growing data center operations. The loan reflects a broader push by federal officials and tech companies to secure reliable nuclear energy sources amid surging electricity demand from AI infrastructure. It follows a wave of similar nuclear investment announcements from both established utilities and startups seeking to capitalize on the same trend.
