- -
- Consumer electronics are replaced by apps that primarily run on smartphones (and tablets).
- -
- Improved material and energy efficiency of display technologies.
- -
- Paper consumption is decreasing as media “moves online”.
- -
- Devices that grow in numbers are small and energy efficient, e.g., IoT devices and IoT communication modules.

ICT Sector Scope and Key Data Sources (For Additional Information See Description in Section 4) | |
---|---|
Data centers (DCs) All use of servers from “in closets” to “hyper scale” DCs | This study relies on studies by Koomey [21] and others in the US [17] plus the new IEA report Digitalization & Energy [22]. Reported data from ICT companies cover about 15% of final estimated electricity consumption. |
ICT networks PSTN (telephony), Mobile networks, Fixed networks | Detailed data from a new report [23] that covers about 40% of mobile and about 15% of fixed subscriptions globally. High-level data for about 70% of all subscriptions have also been collected in this study. |
Enterprise networks (reported with data centers) | Enterprise networks estimated based on average network ports [17] and the authors own experience of operating large “Intranets”. |
ICT user devices | See user devices below and Table 3 for more details. |
E&M sector scope and key data sources (further described in Section 4) | |
Cable-TV and broadcasting (including radio) | These networks have been estimated based on a study in Sweden [24] together with new Swedish data and similar studies in Germany and the US. |
Paper media and printing | Pulp and Paper Industry Intelligence (RISI) estimates of the global paper consumption and its carbon emissions [25]. |
E&M user devices | See user devices below and Table 3 for more details. |
Double accounting adjustments | |
Data centers | To avoid double accounting, ICT network operators and ICT and E&M manufacturer’s data centers have been fully allocated to “Data centers”. |
Enterprise networks and office devices | Network operators and equipment manufacturers own networks and devices included in their reported totals except for personal user devices. |
Cable-TV networks | A share for fixed broadband over Cable-TV have been allocated to ICT network operations. |
