In this paper, we describe about power minimization in cloud computing. Cloud computing is the well-known technology for scaling of extensive data and complex computation. Increasing data volume is giving the bigger task of Data Centers (DCs) to provide a better quality of cloud computing. These DCs, servers, cooling and also security systems consume enormous power, resulting with an increase in CO2 emission and ramp-up in the operational cost. The Power Consumption (PC) rate will increase simultaneously, with DCs size expansion or increase in the number of DCs to fulfill the needs of data storage, processing and hosting demands. However, present and future environment for cloud computing is changing rapidly which ease necessity of Power Efficiency (PE) is balancing. The PC can be minimized by efficient resource management of DC in virtualized manner. This paper discusses a survey on Power Efficiency in Cloud Competing (PECC) to optimize the cost and describes the discussion over green IT technologies. Finally, future work flow towards CC cost optimization is presented.
