Data centers house the servers, storage, networking, and support systems that store and move data and provide computing capacity. AI companies rely on them to train models and run AI services; the same facilities also need substantial, dependable power and cooling to keep equipment operating.
What a data center does
A data center is a working technical facility, not simply a building full of computers. The International Energy Agency (IEA) defines data centres as “facilities used to house servers, storage systems, networking equipment and associated components that are installed in racks and organised into rows.” Those systems supply computing capacity and store and move data for digital services.

The main systems inside
- Servers and accelerators perform computing workloads, including the calculations used to train AI models and respond when people use them.
- Storage retains data and information associated with services and models.
- Networking equipment connects systems within the facility and links them to users and other systems.
- Cooling and environmental controls manage the heat produced by operating equipment. Facilities can use different designs, so no single cooling method or energy share applies everywhere.
- Power and continuity systems deliver electricity and help maintain service availability. The IEA identifies uninterruptible power-supply batteries and backup generators among the supporting equipment.
Why AI companies need data centers
AI models require computing capacity both to be trained and to operate. Data centers bring together the servers, accelerators, storage, networking, power, and cooling needed to provide that capacity. Once a model is deployed, the facility supports the computing involved in serving its users as well as the systems that move and retain relevant data.

AI workloads add to demand for computing infrastructure, but not every facility is an AI data center. Sites vary by workload, scale, operator, deployment model, and efficiency. An enterprise facility is not automatically equivalent to a hyperscale facility, and general-purpose data centers can serve many workloads beyond AI.

How much power AI data centers use
There is no single power figure for an AI data center: capacity depends on the particular facility and its equipment. The IEA gives broad indicative figures of 10–25 megawatts for traditional data centers and says demand by hyperscale AI centers can exceed 100 megawatts. The IEA topic page does not state a publication year for these figures; they are category-level illustrations, not specifications for every site. IEA, Artificial Intelligence topic page
Megawatts describe power capacity, not the amount of electricity used over a period. Actual electricity use depends on how much equipment operates and for how long. Facility-level capacity figures also cannot establish how much energy a particular AI model or individual query uses.

AI-related growth is a projection, not a universal rate
In its 2025 Base Case, the IEA projects electricity consumption from accelerated servers, mainly driven by AI adoption, to grow 30% annually; conventional-server electricity consumption is projected to grow 9% annually. These are scenario projections, not observed growth rates for every company or data center. IEA, Energy and AI (2025)

Computing equipment generates heat, so cooling is part of the infrastructure needed to keep it operating. The energy required for cooling varies substantially with facility type and efficiency. The IEA reports that cooling accounts for about 7% of total data-center consumption in efficient hyperscale facilities, compared with more than 30% in less-efficient enterprise facilities. These are comparisons between facility types, not a universal share for all data centers. IEA, Energy and AI (2025)

Power systems support the computing load, while continuity equipment such as batteries and backup generators helps address interruptions. A facility’s energy and cooling needs therefore depend on its workload, size, equipment, and efficiency—not merely on whether its operator describes it as AI-focused.
What facility-level power figures do—and do not—tell you
Capacity ranges and energy-share comparisons help explain why data centers are significant infrastructure, but they do not calculate the energy or water used by a specific AI service or request. The facility figures above are broad illustrations, and the IEA cooling shares differ by facility type. A per-query figure would require evidence tied to the specific model, hardware, workload, and operating conditions; the cited facility-level information does not establish one.
