How Much Power Will the Data Center Market Need? What Government Energy Data Shows Behind the Boom

The global data center market is experiencing substantial growth as artificial intelligence (AI), cloud computing, and data-intensive applications increase demand for computing infrastructure. This expansion is also driving electricity consumption, creating pressure on power grids, energy suppliers, and infrastructure developers. According to the International Energy Agency (IEA), data centers consumed approximately 485 terawatt-hours (TWh) of electricity in 2025, representing annual growth of 17%. This figure could nearly double to approximately 950 TWh by 2030.

Investors can anticipate the data center market escalating from a 2025 baseline of USD 730.37 billion to nearly USD 2.7 trillion by 2033 at a 14.55% CAGR, according to Kings Research. Increasing AI adoption, enterprise cloud migration, hyperscale infrastructure development, and rising demand for digital services are supporting this expansion.

However, the industry's growth increasingly depends on access to reliable electricity, available grid capacity, and efficient infrastructure. Government energy assessments, electricity pricing studies, and emerging regulatory frameworks provide important insights into how the sector will accommodate rising power requirements.

What Is a Data Center?

A data center is a physical facility that houses and operates large computer systems, including servers, storage devices, and networking equipment. These facilities provide IT infrastructure that organizations use to store, manage, process, and transmit digital information. They also require supporting systems for cooling, power distribution, and backup electricity.

According to the Congressional Research Service (CRS), data centers provide essential IT infrastructure for public and private organizations. Their growing scale has increased attention to electricity consumption, cooling requirements, and the capacity of existing power networks.

What Is Driving Data Center Infrastructure Investment?

The expansion of computing infrastructure is closely associated with the increasing use of AI, cloud services, and enterprise applications. Businesses are investing in additional processing and storage capacity to support digital operations, advanced analytics, and high-performance computing.

AI adoption, cloud computing, enterprise digitalization, streaming, e-commerce, and connected devices are among the major factors supporting industry growth. The increasing deployment of advanced AI models is also driving demand for graphics processing unit (GPU) clusters and high-performance computing environments.

Hyperscale facilities are central to this expansion because they support large computing workloads for cloud platforms and AI applications. Colocation facilities provide another development route by allowing organizations to access shared infrastructure through specialized service providers. These facilities support businesses seeking additional computing capacity while managing infrastructure investment.

However, power availability and land constraints are emerging as significant barriers to new capacity additions. The IEA's October 2026 assessment identifies tighter bottlenecks across energy equipment supply chains and advanced chip manufacturing. These constraints can affect facility commissioning schedules and the pace of infrastructure deployment.

How Much Electricity Do Data Centers Use Today?

Data center electricity consumption varies across countries, reflecting differences in digital infrastructure, computing demand, and the concentration of large-scale facilities.

In the United States, the Lawrence Berkeley National Laboratory (LBNL) estimated electricity consumption at 192 TWh in 2024, equivalent to 4.7% of total U.S. electricity consumption. This estimate falls at the lower end of the range presented in LBNL's earlier assessment. The revision primarily reflects changes in reported GPU shipments and assumptions concerning AI inference server power consumption.

Ireland presents another example of concentrated electricity demand. According to the Central Statistics Office (CSO), data centers accounted for 23% of the country's total metered electricity consumption in 2025. The country's data center electricity consumption increased as facilities expanded their computing operations and infrastructure requirements.

Sources: LBNL and CSO. The reporting periods and measurement methodologies differ.

How Fast Will Data Center Power Demand Grow?

Data center power demand is expected to increase as cloud adoption, artificial intelligence (AI), and other data-intensive applications expand. The growing deployment of high-performance computing infrastructure, AI servers, and hyperscale facilities is adding to electricity requirements, making power availability an increasingly important factor in the sector's expansion.

The U.S. outlook also indicates substantial expansion. LBNL's June 2026 assessment projects electricity consumption of 649 TWh by 2030 under its Reference Case, representing 11.8% of forecast U.S. electricity consumption. Its estimated range spans 521 TWh to 843 TWh, reflecting uncertainty around AI server deployment, equipment efficiency, and utilization.

The assessment also attributes 33% of projected U.S. electricity load growth between 2024 and 2030 to data centers. This indicates that the sector will account for a substantial share of incremental power requirements.

However, the pace of expansion remains subject to infrastructure and supply constraints. The IEA's April 2025 Energy and AI assessment estimated that data centers would account for less than 10% of total global electricity demand growth between 2024 and 2030. This provides context for evaluating their contribution to the wider energy system. 

The IEA's October 2026 assessment also identifies limitations in energy equipment supply chains and advanced chip manufacturing. These constraints could delay facility commissioning and moderate near-term electricity demand growth, even as investment pipelines expand.

Why Are Data Centers Turning to Efficiency Rules and Green Power?

Rising electricity requirements are making energy efficiency an important operating consideration for data center developers and operators. AI workloads require high-density computing infrastructure, increasing demand for electricity and cooling. Improving facility performance can help operators manage operating expenditure while supporting higher computing capacity.

Power Usage Effectiveness (PUE) provides a common measure of facility efficiency. It compares total data center energy consumption with the energy used by IT equipment. A lower PUE indicates that a smaller proportion of electricity is consumed by supporting infrastructure.

LBNL reported that average U.S. data center PUE improved from 1.55 in 2018 to 1.45 in 2024. The improvement primarily reflects the growing contribution of facilities with more efficient infrastructure, including facilities deploying liquid cooling systems for AI servers.

Renewable energy procurement, advanced cooling, and intelligent energy management are also becoming important elements of facility planning. These approaches help operators manage electricity requirements while addressing environmental performance and resource efficiency.

The EU Reporting Rule

The European Union has introduced reporting requirements to improve transparency around data center energy and environmental performance.

Under the Energy Efficiency Directive and Delegated Regulation 2024/1364, operators in Ireland must report performance information when their facilities meet the applicable installed IT power demand threshold. The Government of Ireland's reporting guidance outlines the reporting obligations and the information operators must submit to the European database for data centers.

The reporting framework covers indicators such as energy performance, water usage, and clean energy sourcing. In its September 2026 assessment, the European Commission reported that the main sustainability indicators of European data centers were at a satisfactory level, particularly compared with previous years.

In September 2026, the Commission proposed a common rating scheme for data centers. The proposed label would cover energy efficiency, water efficiency, and low-emission energy sourcing. It would also indicate whether a facility contributes to additional clean energy generation through power purchase agreements with renewable or nuclear plants built within the previous 10 years or substantially refurbished during that period. 

The rating scheme is intended to improve transparency and support comparisons between facilities. It remains a proposal within the EU's wider energy efficiency policy framework.

The U.S. Position

The U.S. regulatory approach differs from the EU framework. According to the Congressional Research Service's May 2026 assessment, explicit legally binding energy standards for the operation of private-sector data centers were absent at the federal level.

The Department of Energy provides guidance for improving energy performance in federal facilities, while ENERGY STAR offers voluntary certification focused on building and infrastructure efficiency. Federal efficiency regulations also cover specific equipment, including computer room air conditioners.

This framework places greater emphasis on guidance, voluntary certification, and equipment-level requirements for private-sector operations. Electricity procurement, grid connections, and facility requirements therefore remain important considerations for developers and operators.

Do Data Centers Raise Electricity Prices for Everyone Else?

The effect of data center expansion on electricity prices depends on local generation capacity, transmission infrastructure, demand growth, and how utilities allocate system costs among customers.

An April 2026 study by LBNL and The Brattle Group, Retail Electricity Price Trends and Drivers: Data Update, 2026 Edition, found that state-level load growth was associated with declining average retail electricity prices in many states between 2019 and 2025. The presence of significant data center and cryptocurrency growth did not appear to change these broader findings.

However, the study's PJM case study highlights the potential price effects of rapid load growth combined with supply and delivery constraints. Rising capacity prices contributed to higher retail electricity prices across several Mid-Atlantic states in 2025. The analysis focuses on electricity prices, while customer bills and the costs and benefits of price increases fall outside its scope.

Ohio provides an example of a regulatory response to large electricity requirements. In AEP Ohio's service territory, the Public Utilities Commission of Ohio approved a tariff requiring new large data centers to pay for a minimum share of their contracted electricity capacity, even when actual consumption falls below the committed amount. The arrangement also includes a defined contractual period.

The Ohio Manufacturers' Association Energy Group appealed the tariff decision to the Supreme Court of Ohio in November 2025. The dispute highlights the debate around infrastructure cost allocation between large electricity customers and other utility customers.

The policy illustrates how utilities and regulators are developing mechanisms to allocate infrastructure costs associated with large new electricity loads.

Which Region Leads the Data Center Market?

Regional market leadership reflects differences in infrastructure investment, cloud adoption, AI development, power availability, and enterprise computing demand.

North America held the largest share of the global data center market in 2025, supported by established hyperscale operators, substantial AI infrastructure investments, and strong enterprise demand.
