The Internet itself consumes significant amounts of electricity. Globally, it accounts for roughly 9–10% of total electricity production, with data centers alone using about 1% of global electricity . The growing number of connected devices—estimated at 30 billion worldwide—further increases energy demand . Data centers, transmission networks, and end-user devices all require electricity to operate, and cooling systems for servers add to the total energy footprint . Without careful management, the Internet's energy consumption could rise substantially, potentially using up to 20% of global electricity by 2025 .
While the Internet does not generate energy, it plays a crucial role in energy optimization through the Internet of Energy (IoE). The IoE uses smart sensors, AI, and connected devices to monitor and manage energy production, distribution, and consumption in real time . For example, smart meters and intelligent appliances allow households and utilities to reduce energy waste, forecast demand, and integrate renewable sources like solar and wind more efficiently . This makes the Internet a powerful tool for improving energy efficiency and reducing carbon emissions, rather than a source of energy itself.
Some data centers and web services are increasingly powered by renewable energy. Companies like Google have begun operating data centers entirely on renewable electricity, demonstrating that the Internet can be aligned with sustainable energy practices . However, this still represents energy consumption rather than energy generation.
In summary, the Internet cannot be considered a new energy source because it does not produce energy. Instead, it is a major consumer of electricity. Its value lies in enabling smarter energy management, optimizing energy efficiency, and supporting the integration of renewable energy systems, which can indirectly reduce overall energy demand and carbon emissions .
