Cloud computing is one of the most important technologies for providing applications to people all around the world. Cloud computing provides a range of services to both users and consumers, including Platform as a Service, Infrastructure as a Service, and Software as a Service. The core system in cloud storage is data centers, which are made up of networked computers. In order to achieve energy efficiency in cloud computing, a variety of techniques and algorithms have been proposed, Virtualization, DVFS (Dynamic Voltage Frequency Scaling) are few among them. To meet the demand request, the cloud data centers are wasting a huge amount of energy. In cloud data centers, inactive computers use a large amount of energy. To minimize data center power usage, we could reduce the number of idle servers by pushing them into sleep mode and then getting them back to active mode as required. During the transition from sleep to active state, there are gaps in extra power usage. Cloud Computing has a major impact on the atmosphere and environment causing pollution and global warming. To reduce the impact of global warming, Green computing is the only way to go.
