The Uncertainty of Data Center Electrical Demand

The Rise of AI and the Effect on Global Power Demand

The rise of digitization, artificial intelligence (AI) and data centers has sparked a digital revolution—and with it, a critical energy conversation. In 2024, there are over 11,000 data centers registered worldwide, reflecting an unprecedented global demand for digital infrastructure. While server installations grew at 4% annually between 2010 and 2020, energy demand plateaued during that time thanks to advances in cooling efficiency and a shift to more efficient cloud data centers.

But in recent years, electricity consumption has surged, as demand for data center services outpaced efficiency gains. In 2022, global data center electricity use was estimated at 240–460 TWh, representing 1–1.5% of total electricity consumption.

AI as a Key Driver of Growth

AI is transforming the data center landscape. While AI applications currently account for a relatively small share of data center electricity use, their rapid adoption is emerging as a significant growth driver.

Consider these numbers:

  1. Over $225 billion was invested in AI startups in the past five years, exceeding the $143 billion invested in clean energy startups during the same period.
  2. In 2023, major players like Alphabet (Google), Meta, Amazon, and Microsoft spent $150 billion on AI and data center infrastructure—equivalent to 0.5% of U.S. GDP.

This boom isn’t confined to developed economies. Emerging markets, such as China and India, are also seeing robust growth in data centers, further driving global demand.

A Manageable Share of Global Electricity Demand

Despite their rapid growth, data centers remain a relatively modest contributor to global electricity demand. Total global electricity consumption is projected to increase by 6,750 TWh by 2030, driven by:

  1. Electrification of transport, industrial processes, and space heating.
  2. Rising demand for appliances and cooling systems.
  3. Emerging markets, which will account for 80% of this additional demand.

Here’s the bigger picture:

  1. Electric vehicles (EVs) and air conditioning will drive demand 3–4 times higher than data centers.
  2. Desalination plants will consume a similar amount of electricity as data centers.
  3. Energy-intensive manufacturing will remain the dominant force behind rising demand.

While data centers are expected to contribute less than 10% of global electricity demand growth, their localized impacts tell a different story.


Localized Challenges: A Clustering Effect

Data centers are often clustered in regions with access to fiber-optic cables, talent hubs, and renewable power sources. This clustering can create significant strain on local power grids, especially when construction outpaces grid expansion.

Examples of localized challenges include:

  1. Ireland: Data centers account for over 20% of national electricity consumption, resulting in the highest electricity costs worldwide.
  2. U.S. States: At least five states report data center electricity usage exceeding 10% of total consumption.
  3. Singapore: Before a moratorium on new developments in 2019, data centers consumed 7% of national electricity.

A single hyperscale data center can consume as much electricity as a steel plant, but clusters of data centers amplify this demand within small geographic areas, intensifying grid strain.

These localized challenges raise critical questions about the sustainability and scalability of data center growth—questions further complicated by the uncertainty in predicting future energy demand.


Sustainability and Clean Energy

As data centers grow, they are becoming some of the most active buyers of clean energy. Companies like Amazon, Meta, Alphabet, and Microsoft are leading the way through Power Purchase Agreements (PPAs). Between 2023 and 2030, demand growth from data centers is expected to account for just under 50% of the annual increase in low-emissions electricity, demonstrating that meeting this demand sustainably is possible.

Efforts to enhance sustainability include:

  1. Scaling up low-emissions electricity supplies.
  2. Improving energy efficiency and operational transparency.
  3. Aligning incentives through policy reforms and collaborative frameworks.

But achieving sustainability at this scale requires more than clean energy initiatives—it demands a deeper understanding of how data centers will evolve.


Minimizing the Risk of Trade-Offs: Understanding the Outlook

With data centers playing an increasingly central role in the electricity system, policymakers and regulators must have the tools to assess and plan for this new driver of demand growth. Several key areas require further exploration:

1.                      AI Growth Patterns:

·        The speed and manner in which AI use will grow remains fundamentally uncertain.

·        Early data suggests household adoption is faster than previous digital technologies. For example, video generation is far more energy-intensive than text-based tools, which will shape energy demand.

·        Financial returns from AI applications will also influence data center investment trends, as current spending is tied to profitability expectations.

2.                      Efficiency Improvements:

·        AI chip efficiency has doubled every 2.5–3 years, with modern chips using 99% less power than their 2008 counterparts.

·        Despite ongoing progress, the energy performance of data centers remains opaque, making demand estimates challenging. Efforts to improve transparency are underway.

3.                      Physical Constraints:

·        Limited understanding of the data center project pipeline and supply chain bottlenecks—such as AI chip production—adds complexity.

·        Power generation and grid capacity may hinder growth if infrastructure in key regions fails to keep up.

4.                      AI’s Role in Energy Innovation:

·        AI applications could transform energy systems by facilitating breakthroughs in clean energy innovation, improving grid management for renewable energy, and accelerating electrification programs in developing economies.


Balancing Growth and Sustainability: Collaboration is Key

The rise of AI and data centers presents an exciting challenge: how can we meet growing demand while staying sustainable? The answer lies in collaboration. Policymakers, industry leaders, and energy providers must work together to:

  1. Enhance regulatory frameworks and align incentives.
  2. Scale up clean energy supplies to meet demand sustainably.
  3. Improve data-sharing and forecasting to make smarter decisions.

The upcoming Global Conference on Energy & AI aims to advance these critical conversations, bringing together policymakers, tech leaders, and the energy industry to explore solutions.

Data centers are here to stay—but whether their growth aligns with a sustainable energy future depends on the choices we make today.

What’s your perspective? Are we ready to meet the energy demands of the digital age, or are we underestimating the challenges ahead?
