Green cloud computing is a catchall phrase that includes efforts to improve sustainability both with in the IT industry and outside of it . The green IT movement seeks to reduce energy use ,waste, and toxic substances by IT industry.In many other industries mobile and computing devices connected to network enable sustainability through automation ,virtualization and reduced travel.Green computing is a topic of increasing importance with IT industry.Cloud computing technologies have high performance at relatively low cost. With the increasing growth of large data storage and computational demand, Green Cloud Computing is known to be a broad area and hot field for research. Green Cloud computing is environment friendly. Green cloud computing is the study of designing, producing and using digital devices in a way that reduces their impact on the environment. Not only can these solutions save energy but can also reduce operational cost. Green cloud computing involves designing, producing, and using digital spaces in a manner to reduce its impact on the environment. A green cloud solution can not only save energy but significantly reduce enterprise operational costs. Green cloud computing allows users to utilize the benefits of cloud storage while decreasing its adverse effects on the environment, ultimately affecting human well-being. The goals of green computing are similar to green chemistry ,reduce the use of hazardous materials,maximize energy efficiency during the product lifetime and promote the recylability or biodegradability of defunct products and factory waste. These technologies have the potential to improve energy efficiency and to reduce carbon footprints and (e-)waste. These features can transform cloud computing into green cloud computing. To protect our environment from cloud negative impacts, the service providers must adopt and update their cloud infrastructure towards green computing. Green computing methodologies can help us to build a protected place for us to live in. Green computing researches widely focus on designing of efficient clouds with green characteristics like Power Management, Virtualization, High Performance Computing, Load balancing, Green data center etc. As part of my research on green clouds, this paper presents an analysis report about the green cloud computing and its characteristics in detailed manner. This paper thoroughly discusses about the former green computing achievements, current trending concepts of green computing and future research challenges as well. This comprehensive green cloud analysis report helps the naïve green research fellows to learn about green cloud topics and to understand the green cloud future research challenges.
