A survey on current trends to future trends in green computing

Abstract: Cloud computing is not limited to reduce the capital expenditure but also used to perform trillions of computations per second in consumer-oriented applications such as financial portfolios to deliver personalized information, to provide data storage or immersive computer games. The purpose of the paper is to provide an overall management perspective of cloud computing with the aim to highlight the management that should be properly addressed and managed to realize the full potential of cloud computing. The cloud computing concept offers dynamically scalable resources provisioned as a service over the internet. Economic benefits are the main driver for the cloud since it promises the reduction of capital expenditure and operational expenditure.

Abstract: Over the past few years human beings have become completely dependent on computers and IT technologies, which in turn have led to the issue of energy and power consumption in IT industries. Since the energy cost as well as the electrical requirements of the industry has increased drastically throughout the world, therefore it has become necessary to shift our focus to Green computing, which refers to environmentally sustainable computing and aims to limit energy and power consumption and shrink costs thus maximizing the efficiency of the system. Green Computing provides the proficient use of computing power.

Abstract: Energy efficiency is increasingly important for future information and communication technologies (ICT), because the increased usage of ICT, together with increasing energy costs and the need to reduce green house gas emissions call for energy-efficient technologies that decrease the overall energy consumption of computation, storage and communications. Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilization of data centre resources. In principle, cloud computing can be an inherently energy-efficient technology for ICT provided that its potential for significant energy savings that have so far focused on hardware aspects, can be fully explored with respect to system operation and networking aspects. Thus this paper, in the context of cloud computing, reviews the usage of methods and technologies currently used for energy-efficient operation of computer hardware and network infrastructure. After surveying some of the current best practice and relevant literature in this area, this paper identifies some of the remaining key research challenges that arise when such energy-saving techniques are extended for use in cloud computing environments.

Abstract: Green computing or sustainability is not simply the operational energy consumption of computing equipment. Green computing must take the product life cycle into consideration, from production to operation to recycling. This study focuses on the production and the operation phases of the product life cycle and demonstrates what actions will result in overall carbon footprint reduction for personal and business computing under various operational conditions and environments. Energy consumption related to end-of-life product recycling is not discussed in this study and is not believed to have a significant impact on the validity of the sustainability analysis based on production and operation energy consumption and carbon footprint.

Abstract: ICT has now become an important department for the success of any organisation. Most of the businesses rely on the many benefits computers provide by using computing resources to perform a multitude of tasks, including work, research, teaching and learning. However the IT department is usually always the one department that uses the most amount of power which in turn is an excessive amount of overhead for a business as well as a source for toxic waste. Making IT “Green” can not only save money but help save our world by making it a better place through reducing and/or eliminating wasteful practices and using nontoxic materials. While using ICT, many institutions are a source for excessive power use, excessive spending of resources, and uses many toxic materials. All of these items are bad practices and converting a company’s IT department to a more streamlined green concept is far more cost effective as well as better use of resources. This paper examines the need and provides a guideline which highlights our responsibilities as computer users and encourages us to take actions that maximize the usefulness of these amazing tools while minimizing the negative consequences that may occur during their use.

Abstract: There is an increasing appreciation by information technology practitioners and researchers of the emerging discipline of sustainable IT. This is motivated by a growing awareness and concern about IT's impact on the environment. Sustainable IT has been generally defined to encompass strategies that lead to the more efficient use of computing resources while maintaining or increasing overall information system performance. The initial stage of sustainable IT development, often called "Green IT," has focused on reducing energy costs, primarily in data centers. Although green IT solutions have been mostly product-oriented and internal to the IT function, sustainable IT's potential as a service to the organization and to society is much larger. As IT's role and potential impact on corporate sustainability becomes better defined, expectations for specific IT performance outcomes in the corporate social responsibility (CSR) domain will increase. To fully understand the opportunities and responsibilities facing IT departments as they embrace sustainable IT, a better understanding of CSR as it might apply to the development of future IT services is needed. The purpose of this paper is to define the CSR dimensions that impact IT, review the current state of sustainable IT, and review the sustainable IT initiatives of IT companies that are viewed as leaders in CSR as they plan for the future of sustainable IT.
