Energy demand from AI – Energy and AI – Analysis - IEA

Executive summary

The IEA forecasts that global data centre electricity consumption will double by 2030, largely due to AI adoption. Europe, including the UK, is projected to see a 70% increase in data centre electricity demand over this period, posing challenges for grid integration due to geographical concentration.

Reporting based on iea.org

Why it matters

This report highlights the significant and growing energy demands of AI infrastructure, which is particularly relevant for the UK given its ambitions in AI and its ongoing efforts to decarbonise and reinforce its energy grid. The concentrated nature of data centre demand will necessitate strategic planning for grid capacity and supply, especially as the UK transitions towards greater reliance on renewable energy sources.

Analysis by AI Energy Intelligence UK

UK electricity demand

Global electricity consumption for data centres is projected to double to approximately 945 TWh by 2030, reaching just under 3% of total global electricity consumption. In Europe, data centre electricity demand is expected to grow by over 45 TWh (a 70% increase) by 2030, driven significantly by accelerated servers used for AI.

UK energy security

While data centres' absolute growth in electricity demand may seem smaller than other drivers, their tendency to concentrate in specific locations makes grid integration potentially more challenging, which could impact regional energy security and grid stability, particularly given the UK's dense population and established infrastructure.

Businesses

The rapid growth in electricity demand for AI-driven data centres implies a significant and increasing operational cost for businesses heavily reliant on AI. The need for resilient power supply will drive investment in grid infrastructure and potentially on-site generation, influencing business location decisions and operational models for data centre operators.

Consumers

The analysis does not directly address the impact on UK consumers. However, increased energy demand from data centres could, indirectly, place upward pressure on electricity prices or necessitate further investment in grid infrastructure, costs which could eventually be borne by consumers.

Long-term implications

The long-term implications point to a sustained and accelerating demand for electricity from the AI sector. Without significant advancements in energy efficiency for both hardware and software, the energy footprint of AI could continue to expand, challenging energy supply infrastructure and potentially hindering decarbonisation efforts if not met by low-carbon sources.

Frequently asked questions

How much is data centre electricity demand expected to grow in Europe?

In Europe, data centre electricity consumption is projected to grow by more than 45 TWh, representing a 70% increase from 2024 levels, by 2030.

What is driving this increased electricity demand?

The rise of AI is accelerating the deployment of high-performance accelerated servers, which consume significantly more electricity than conventional servers, thus driving the increased demand.

Why is the geographical concentration of data centres an issue?

Data centres tend to concentrate in specific locations, which can make their integration into the electricity grid more challenging compared to other forms of electricity demand growth, such as electric vehicles.
