Abstract
The information and communicationtechnology (ICT) is closely related to the future ofglobal energy consumption, not only because theICT equipment itself increasingly consumesenergy, but also because it is a general-purposetechnology, which may affect energy use of almostall sectors. The growing demand for ICT devicesand services outpaces the efficiency gains ofindividual devices. Previous studies had alludedthat cumulated potentials for ICT-induced savingsis several times larger than the entire energyconsumption of ICT itself. More studies on ICTrelated energy consumption do exist, and anincreasing number of studies looking at ICTinduced energy efficiency. The few studies,however, considering both aspects, typically do soindependently, without relating the two aspects.Moreover, in the energy efficiency discourse, ICTis usually treated as a monolithic block oftechnologies – only the application areas that areexpected to benefit from it being differentiated. Itis only by consequently following low energyconsumption targets for technologies with a lowenergy efficiency potential, while at the same timenot suffocating technologies with a high-energyefficiency potential through restrictiveconsumption targets, this paper will discuss thevarious emerging trends in energy consumptionswithin ICT devices.
