Accounting for the energy consumption of personal computing including portable devices

In light of the increased awareness of global energy consumption, questions are also being asked about the contribution of computing equipment. Though studies have documented the share of energy consumption due to these equipment over the years, these have rarely characterized the increasing share contributed by the rapidly growing portable computing segment. The portable computing device segment is widely predicted to be a dominant mode of computing and communication, and accounting for its energy consumption is necessary for energy-efficient computing in the future. This work takes a fresh and updated look at the energy consumption due to computing devices in perspective of global consumption, and pays special attention to the contribution of portable computing devices. We further quantify the impact of energy consumed by the computing sector on the environment, as well as on the electricity cost to an average residential consumer. Finally, based on the results of the study, recomme...
