The rapid growth of Cloud computing, Data Centers and Digital Services have helped to reduce the worldwide environmental degradation caused by energy consumption. Information Technology (IT) has become a significant source for Carbon emissions, consumption of electricity and electronic waste. Therefore Sustainable and Green Computing has emerged as an important model to address these issues through increased Energy Efficiency, Incorporation of Renewable Energy, and Implementation of Lifecycle Oriented IT Policies. This research provides a detailed overview of both Sustainable and Green Computing focusing primarily on the Incorporation of Renewable Energy into Low Energy Data Centers, Eco-Friendly Cloud Computing, and Lifecycle Assessments for IT and Legislation governing IT. It's been stated in research that there is an immediate shift away from traditional green computing techniques to sustainable IT solutions that achieve social, economic, and environmental objectives over a longer duration. In addition, the research findings have identified a deficiency of research in the area of sustainable computing and have also criticised the current methods for researching areas of sustainable computing...
