The Evolving Role of Data Centres in Global Energy Consumption
Data centres are quickly becoming significant players in the global energy landscape. Today, they consume approximately 415 terawatt hours (TWh) of electricity, which represents about 1.5% of the world’s electricity consumption in 2024. With an annual growth rate of 12% over the past five years, the trajectory for future energy demand is steep. The rise of artificial intelligence (AI) is accelerating the deployment of high-performance servers, which increases power densities in data centres. Understanding the swift pace and scalable adoption of these technologies is essential for forecasting future electricity requirements.
Uncertainty and Scenario Planning in Data Centre Consumption
There is considerable uncertainty surrounding current and future data centre electricity consumption due to rapid technological advancements. To navigate this uncertainty, a scenario-based approach is crucial. By exploring different pathways, stakeholders in the energy sector gain insights into the potential timelines and strategic decisions. Importantly, as the technology sector can operationalize a data centre within two to three years, energy systems often face longer lead times, necessitating early and strategic planning.
Scenario Analysis: Exploring Different Futures
Three sensitivity cases—Lift-Off, High Efficiency, and Headwinds—represent potential scenarios for future developments in data centre efficiency and AI-driven server use. These scenarios encapsulate variations in hardware/software advancements, AI penetration, and potential bottlenecks in the energy sector.
Projected Growth in Data Centre Electricity Consumption
Our Base Case projection estimates that global electricity consumption by data centres will double by 2030, reaching around 945 TWh, just under 3% of total global electricity consumption. Between 2024 and 2030, data centre demand is projected to grow at an annual rate of 15%, significantly outpacing total electricity consumption growth from other sectors. While a 3% share in 2030 won’t dominate, it illustrates the rapidly rising importance of these technological hubs.
The Future of Accelerated Servers and AI
AI adoption is driving a surge in electricity consumption for accelerated servers, with annual growth expected to reach 30% in the Base Case scenario, compared to 9% for conventional servers. These accelerated servers will account for nearly half of the net increase in global data centre electricity consumption, underscoring AI’s profound impact on energy use patterns.
Other IT equipment and infrastructure, such as cooling systems, are expected to consume a smaller but significant portion of the net electricity increase—about 10% and 20%, respectively. All data centre types, including enterprise, colocation, and hyperscale, are contributors to this upward trend.
