Digital infrastructure and data center networks powering the Internet

Recent studies leave little doubt: our online activities require a considerable amount of energy. Telecommunications networks, data centers, computer equipment and billions of connected devices now account for a significant share of global electricity consumption and contribute to greenhouse gas emissions worldwide.

And this trend is unlikely to slow down anytime soon. The number of Internet users continues to rise, while our digital habits become increasingly data-intensive. Cloud computing, artificial intelligence, video streaming, online storage services and connected devices all require ever-growing computing resources. Many experts believe that managing the energy demands of the digital economy could become one of the major challenges of the coming decades.

What's Driving Internet Energy Consumption?

The explanation is straightforward: the number of users continues to grow rapidly, while digital services consume more resources than ever before. Video streaming alone represents a substantial share of global Internet traffic. Every day, billions of videos are watched across streaming platforms, social media networks and video conferencing services.

Despite common misconceptions, the digital world is far from intangible. Every video streamed, every email stored and every photo saved in the cloud relies on servers, network infrastructure and electronic equipment operating around the clock.

Internet routers, smart TVs, computers, smartphones and countless other connected devices also contribute to overall electricity consumption. Individually their impact may appear modest, but multiplied by billions of users worldwide, the cumulative effect becomes substantial.

AI, Cloud Computing and the Next Wave of Demand

The rapid growth of artificial intelligence could further accelerate this trend. Training and operating advanced AI models requires enormous computing power, leading to the construction of increasingly powerful data centers throughout the world.

Autonomous vehicles raise similar questions. Their operation depends on numerous sensors, onboard processors and continuous data exchanges. While these technologies offer significant benefits, they may also increase the energy required for processing and storing information.

Efficiency Gains Are Helping to Limit Growth

At the same time, technological progress continues to improve energy efficiency. Modern data centers consume less electricity for the same amount of computing power than they did only a few years ago, while manufacturers constantly work to reduce the energy requirements of digital equipment.

This ongoing improvement helps explain why some of the most alarming predictions published in the past have not materialized. However, that does not mean the issue has disappeared. Digital usage continues to expand rapidly, driving overall energy demand higher despite efficiency gains.

Can Individuals Make a Difference?

No one can say with certainty whether the Internet and digital technologies will eventually consume a major share of global electricity production. What is certain, however, is that the continued growth of digital services raises important environmental and energy-related questions that societies around the world will need to address.

In the meantime, individuals can adopt a few simple habits: avoid storing thousands of unnecessary emails, regularly organize digital files, limit excessive cloud storage, reduce unnecessary video streaming and switch off electronic devices when they are not being used.

These actions may seem modest on an individual level, but when adopted by millions of users, their combined impact can become meaningful.
