Cloud computing offers a utility based service by sharing resources for its clients through using Internet. Because of well advantage features, the popularity of such cloud computing growing very rapidly. As a result, power consumption by cloud data center also increase continuously. Data centers consume lot of electrical power that effects indirectly to the carbon dioxide emission in environment. Beside this, there have many other factors which also effect the power consumption of cloud environment-communication equipments which act as a bridge between users to cloud data center, user devices that are also contribute a small amount of consumption in cloud network. This paper offers a theoretical model that brings down the energy by proper maintenance of overall cloud network.
