- Abstract:
- Electricity demand is rising rapidly, along with growing enthusiasm for nuclear power. In addition to climate concerns and the desire for secure energy, these needs are driven in large part by the planned expansion of data centers for artificial intelligence and cloud computing. The United States is home to the world’s largest data center market and the leading global cloud service providers, including Alphabet (Google), Amazon, Meta (Facebook), and Microsoft. These firms—or “hyperscalers”—design, build, and operate massive data center facilities that support skyrocketing AI demands, but require large amounts of firm, scalable, and always-available power. This puts new pressure on electricity grids already facing capacity, reliability, and affordability challenges. As technology companies pursue aggressive AI buildouts, they are seeking innovative ways to meet their energy demands. Nuclear power has thus entered the conversation as one of the few energy sources capable of delivering the kind of firm, high-density electricity that data centers need while simultaneously allowing companies to maintain public climate commitments.1 The entry of hyperscalers into a rapidly evolving nuclear energy market introduces new dynamics to what has been a highly regulated and slow-moving industry. Since 2024, a series of high-profile agreements have been announced between hyperscalers and nuclear utilities, vendors, and reactor designers. These deals signal enthusiasm for the sector, but it is still unclear whether big tech is willing to make big bets on nuclear power. This paper explores how large U.S. technology companies are approaching nuclear power in the context of their energy strategies to meet the escalating demands from AI. The first section describes the approaches hyperscalers are using to secure nuclear energy. To date, their efforts reflect their preference to be energy offtakers (customers) over direct nuclear ownership or project development. The second section then assesses why these approaches have remained cautious, considering factors such as priorities, timing, and costs. Additionally, it considers key entanglement risks that big tech will need to confront including potential reputational exposure, nonproliferation concerns, and management of long-term nuclear waste.
