This article presents a review of the methodological approaches used so far in such assessments: i) top–down analyses based on estimates of the overall Internet energy consumption and the overall Internet traffic, whereby average energy intensity is calculated by dividing. This article presents a review of the methodological approaches used so far in such assessments: i) top–down analyses based on estimates of the overall Internet energy consumption and the overall Internet traffic, whereby average energy intensity is calculated by dividing. The energy requirements for the Internet infrastructure has become harder to manage due to the increase in connected devices and digital traffic. This research analyzes energy usage patterns throughout the Internet topology, focusing on the operational parameters of routers, access points, and data. SUMMARY This paper summarizes recent reports on the internet's en-ergy consumption and the internet's benefits on climate actions. It discusses energy-e ciency and the need for a common standard for evaluating the climate impact of future communication technologies and suggests a model that can be. In 2025, the internet is expected to consume a substantial amount of energy, with data centres using around 536 terawatt-hours (TWh), or roughly 2% of global electricity. The figure encompasses the power needed for servers, cooling systems, and network infrastructure, with the rapid expansion of. Data centers, housing the servers that store, process, and distribute data, are arguably the most significant energy consumers in the Internet ecosystem. They require substantial power not only for computing but also for maintaining stable operating temperatures. 0064kilowatt-hours per gigabyte (kWh/GB) to 136kWh/GB. The main driver is the energy consumption of AI, plus blockchains, rising traffic, and offset by rising efficiency.
