The International Energy Agency projects that electricity demand from AI data centers will more than double by 2030, a shift that is already reshaping utility, nuclear and fuel-cell stocks. Companies from Bloom Energy to NextEra Energy are positioning for the surge in ways suited to different types of investors.
The International Energy Agency projects that electricity demand from AI data centers will rise from 415 terawatt-hours to 945 terawatt-hours between 2024 and 2030, more than doubling in six years. By 2035, the agency puts that figure at 1,200 TWh, nearly triple the 2024 level.
The scale behind the IEA numbers
The IEA notes that 945 TWh of demand in 2030 will exceed Japan's current total power use. Data center electricity use has climbed 12% a year since 2017, more than four times the overall growth rate in electricity consumption. Separately, the agency's April 2025 "Energy and AI" report found that 945 TWh is close to the entire annual electricity consumption of France and Germany combined.
Utilities and fuel-cell makers position for the buildout
Bloom Energy's hydrogen fuel cells supply off-grid power to data centers, and the company entered 2026 with a product backlog of $6 billion, up 140% over its 2025 starting backlog, plus a $14 billion service backlog. Constellation Energy, one of the largest nuclear plant operators in the United States, is already working with AI companies including Meta and Microsoft and, unlike a regulated utility, can charge market rates for its power.
Cameco, a major uranium producer based in Canada, expects nuclear fuel demand to outstrip supply by the mid-2030s. NextEra Energy, a regulated utility with more than three decades of annual dividend hikes and a 3% yield, is pursuing a pending acquisition of Dominion Energy, which holds a monopoly in one of the world's largest data center markets.
The grid, not construction, is the bottleneck
Data centers can be built in 18 to 24 months, but new transmission lines and generation capacity often take five to ten years to permit and construct. That mismatch is straining grids in regions such as Northern Virginia, central Texas and the US Southeast, where data center clusters are concentrated. The IEA also expects the United States and China to account for nearly 80% of the total global increase in data center electricity demand through 2030.
Grid buildout timelines, not chip supply or capital, now set the pace at which that 945 TWh of demand can actually be met.
