The Total Energy Model of connected devices is updated and interactive!

Globally, the number of network-connected devices such as mobile phones, thermostats, sensors, and voice assistants is increasing, with significant consequences on worldwide energy consumption. Network-connected devices require energy to communicate over the network and perform their functions. Further energy consumption results from sending and receiving data over a wide area network (WAN) and data centers.

The Total Energy Model - TEM model considers the energy consumption of the main function of network connected devices, and the upstream energy consumption for transmitting and processing the data. This includes the energy consumption of LAN devices as well as the additional energy consumption resulting from the network connection. The energy consumption of the network is subdivided in both active and standby states. Energy consumption can be estimated for different world regions and product categories.
