The depletion of fossil energy has become one of the major challenges for mankind to sustain the civilization. In addition, overindulgent energy consumption causes over emission of green-house gas, which, according to expert consensus, is a root cause for the current global warming. Cloud computing is emerging as a critical information communication technology to heavily impact their daily life in the future. The authors systematically analyze its energy consumption based on types of services and obtain the conditions to facilitate green cloud computing to save overall energy consumption in the related information communication systems. With a tremendously increasing number of mobile devices, green mobile communications would be the foundation of green cloud computing.
