Compute and energy

Training and running AI requires specialised chips, data centres, electricity, cooling water and network capacity. Demand is growing quickly and concentrating in particular places, with effects on power grids, water resources and emissions. This page sets out how AI compute uses energy and water, how those uses are measured, and what evidence serves the grid operators, planners and policymakers who must accommodate them.

02The question

Compute and energy: how the risk develops.

Compute concentration, efficiency and demand. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Training and inference both use energy

Training a large model uses a large amount of electricity once; inference uses less per query but runs continuously at scale, and can dominate over a model’s life.

Mechanism

Data centres strain local grids

Large data centres need connections comparable to industrial plants. Clusters in one region can outpace grid and generation build-out.

Mechanism

Cooling uses water

Evaporative cooling and electricity generation consume water. Where water is scarce, data centre siting competes with other uses.

Mechanism

Efficiency and demand move together

Hardware and software efficiency improve quickly, but lower costs can raise total use. Net energy demand depends on both.

A cascade through interdependent networks.

A hazard footprint takes out co-located assets in every layer; fragmentation, dependency between layers and overload of the survivors then spread the failure. The 3D view separates the layers by depth. Teaching model with stated illustrative values, not a prediction. The map on this page shows East Asia; the model itself is not tied to a place.

12Core questions

What researchers ask about compute.

  • How concentrated are chip manufacturing, cloud capacity and frontier model training, and what follows from that?
  • How much energy and water do training and inference use, and how is that changing?
  • How much do efficiency gains offset growth in demand?
  • Who has access to compute for research and public-interest uses?
13Mechanisms

Concentration, efficiency and demand.

Advanced chip fabrication is concentrated in very few facilities, and a small number of cloud providers supply much of the compute for AI. That concentration creates shared exposure to disruption, from natural hazards to export controls, and shapes who can build large models.

Hardware and algorithms become more efficient over time, but cheaper computation tends to increase total use, an effect known as the rebound or Jevons effect. Data centres draw large, steady electricity loads that can strain local grids and, where they use evaporative cooling, water supplies. Inference, the everyday use of models, can come to outweigh training in total energy use.

14Methods and data

Measuring compute and its footprint.

  1. 01

    Energy accounting

    Estimating energy per training run and per query, using high-performance, cloud and edge computing. Providers disclose little, so estimates carry wide uncertainty.

  2. 02

    Supply-chain mapping

    Tracing chips, materials and facilities to identify concentration and single points of failure.

  3. 03

    Scenario analysis

    Projecting demand under different assumptions about efficiency and adoption, with probability and statistics. Projections are scenarios, not forecasts.

  4. 04

    Access studies

    Assessing which researchers and institutions can obtain compute, and on what terms.

17Questions

Questions and answers.

How much energy does AI use?
Estimates vary widely. Data centres use a growing share of electricity, and AI is a fast-growing part of that, according to the IEA, but precise figures depend on assumptions and disclosure.
What is power usage effectiveness?
The ratio of a data centre’s total energy use to the energy used by its IT equipment; values closer to one mean less overhead for cooling and power conversion.
Why does AI use water?
Mainly for cooling data centres, especially with evaporative systems, and indirectly through the water used to generate electricity.
Will efficiency gains reduce AI’s energy use?
Not necessarily. Efficiency lowers the cost per task, which can increase total demand. The net effect depends on adoption and use.
Why does water matter for data centres?
Many use evaporative cooling, which consumes water. In water-stressed areas, this competes with other uses, linking AI to local water risk.
Does the platform allocate compute?
No. Compute allocations for Consortium projects are a separate matter of Foundry and the annual programme, and open only when their terms exist.
Can energy figures be trusted?
Published estimates vary with assumptions about hardware, utilisation and location. The platform reports ranges with their sources and assumptions.
