Abstract Global warming is the greatest test for environment now a days and cloud computing is one of the main motivation for an unnatural weather change as global warming. After numerous years of examination in systems administration, virtualization and distributed computing feld Cloud Computing was assembled. Cloud Computing is one of the best innovation in IT feld. The fundamental standard of Cloud Computing is to process on distributed PCs instead of fguring on stand alone or remote servers. The thought behind Cloud Computing is to give secured, quick and appropriate data storage and fguring administrations. As there is a positive side of any innovation there is likewise a negative side of it, so do could computing has its negative side. There is huge measure of energy wastage furthermore huge carbon dioxide discharge in cloud computing which is the most compelling motivation for a dangerous atmospheric deviation. Hence there ought to be an approach to decrease the energy utilization furthermore diminishes the discharge of perils components like carbon dioxide. Giving a green solution for cloud computing is important to diminish contamination and utilization of energy. For this we should examine the power utilization in cloud computing and examination should be done in both private and public cloud. Green Cloud Computing Solution decreases energy utilization and consequently lessens the operational coasts in cloud computing furthermore spares energy, henceforth, diminishes the negative impacts on environment. This work tries to actualize the task combination (consolidation) Study of Green Algorithm in Cloud Computing for Effcient Energy Consumption Abhinandan Prafull Mangaonkar*, Anand Diggikar** Article can be accessed online at http://www.publishingindia.com 1. Introducton Cloud computing is computing of various concepts where real-time communication takes place between thousands of computer systems to fulfll the user’s needs, where user feels that as if he/she using a single large resource. Cloud computing provides larger numbers of computing resources, applications, storage for huge amount of data and many more. Another advantage of Cloud computing is that, the users of Cloud services need to pay only for the services they use from cloud and no other extra amount. Because of these utilities provided by the Cloud computing, numerous organizations and consumers are using cloud services and day by day as needs are increasing Cloud computing feld is also growing. The main objective of Cloud computing is to provide maximum numbers of shared resources and support for user requests in real time and on other hand the major disadvantage is its unnecessary power consumption, great amount of energy loss and higher infrastructure cost. * Mtech Student, Computer Science and Engineering, KLS Gogte Institute of Technology, Visvesvaraya Technological University, Belagavi, Karnataka, India.
