Worldwide power consumption for data centers is expected to double by 2030, with artificial intelligence (AI) accounting for about half of the demand. In 2025 AI was about one-third of data center power demand, and that number is expected to grow to one-half by 2030. The energy research firm BloombergNEF has forecast that data centers in the United States could reach a demand of 194 gigawatts, or one-fifth of all American electricity generation, by 2035.
