Global warming is now a major social concern. Stemming the growth of CO2 in the atmosphere is imperative. Fossil fuel is a major source of CO2. The Great East Japan Earthquake has shown that over-dependence on nuclear energy carries a heavy risk. Thus, power consumption must be reduced. Considering the fact that the ICT industry is a major power consumer, the wasteful activities of ICT devices must be detected and eliminated. In this paper the authors examine the use of existing network management information to make transparent the power-on/off state of ICT devices in intranets.
