How big is the energy internet

The energy internet, encompassing global internet infrastructure, consumes hundreds of terawatt-hours annually and could account for up to 5% of global electricity by 2050, while conceptually it represents a decentralized, smart network integrating renewable energy and digital connectivity.

Quantitative Scope

The energy footprint of the internet is substantial and growing. In 2022, global internet infrastructure consumed approximately 800 terawatt-hours (TWh) of electricity, driven by 5 billion users generating 4. 7 zettabytes of data traffic.

By 2025, data centers alone are projected to use around 536 TWh, roughly 2% of global electricity, with AI and digital services contributing to rising demand. Some estimates suggest that by 2030, internet energy consumption could double, potentially reaching 5% of global electricity use by 2050. For context, the internet currently uses more electricity than the United Kingdom and is responsible for roughly one billion tonnes of CO₂ emissions annually.

The main contributors to this energy use include: Data centers: Servers, cooling systems, and storage facilities are the largest consumers. Network infrastructure: Routers, switches, and transmission lines that transport data globally. End-user devices: Computers, smartphones, and tablets, which collectively add significant energy demand.

The “last mile”: Connections between networks and individual users, often less efficient. Conceptual Scope: The Energy InternetBeyond raw energy consumption, the energy internet is a vision for a smart, decentralized energy network that integrates renewable energy sources with digital connectivity. Proposed by Jeremy Rifkin as part of the Third Industrial Revolution, it aims to: Enable multi-directional flows of renewable energy.

Support smart grids and digital manufacturing. Reduce energy poverty and create millions of jobs globally. Leverage big data and AI to optimize energy production, distribution, and consumption.

This conceptual energy internet is not just about electricity usage but about transforming energy systems to be more sustainable, efficient, and responsive to real-time demand.

Summary

The energy internet is both massive in scale and strategically transformative. Quantitatively, it already consumes hundreds of TWh annually and could reach 5% of global electricity by mid-century. Conceptually, it represents a decentralized, intelligent network that integrates renewable energy, digital infrastructure, and smart grid technologies to reshape global energy production and consumption patterns.
