In modern communications, as with every form of communication, a message is sent from a transmitter via a channel to a receiver. A smartphone is used daily, to communicate, navigate via GPS, or call up information from the Web. In this context, the graphic shows devices and transmitters with their annual energy requirement in kilowatt-hours (kWh). Most users have little idea about the amounts of energy (particularly electric power) that are needed for this modern communications technology. Servers, for example, need energy for uninterrupted operation and for the required cooling of equipment.

Information and ideas:
This topic raises questions such as: How much energy is needed worldwide for mobile radio communications? What could this energy otherwise be used for?
