Cloud computing has penetrated the lives of many through the way we process data, manage, and store it. But there are also serious energy usage and environmental issues as a result of this quick expansion. A key paradigm for reducing the negative environmental effects of cloud services is green cloud computing, which emphasizes sustainable practices and increased energy efficiency. Since technology is always developing, new gadgets that potentially have a variety of negative environmental repercussions are being created. The purpose of this study is to evaluate several aspects of green computing. Bibliometric reports of published studies were analysed and the countries in which they were conducted were compared. Analysis was done in the many theme areas where it was stated what the future and present research tendencies in those areas are. The study yielded insightful data that was used to project future research in this field.
