Energy challenges for ICT

The energy consumption from the expanding use of information and communications technology (ICT) is unsustainable with present drivers, and it will impact heavily on the future climate change. However, ICT devices have the potential to contribute signi - cantly to the reduction of CO2 emission and enhance resource e ciency in other sectors, e.g., transportation (through intelligent transportation and advanced driver assistance systems and self-driving vehicles), heating (through smart building control), and manu- facturing (through digital automation based on smart autonomous sensors). To address the energy sustainability of ICT and capture the full potential of ICT in resource e - ciency, a multidisciplinary ICT-energy community needs to be brought together cover- ing devices, microarchitectures, ultra large-scale integration (ULSI), high-performance computing (HPC), energy harvesting, energy storage, system design, embedded sys- tems, e cient electronics, static analysis, and computation. In this chapter, we introduce challenges and opportunities in this emerging eld and a common framework to strive towards energy-sustainable ICT

Assessing Green Information Technology/ System capabilities and practices within a University context

The IT industry has responded to the call for change, with the looming climate change agenda, through greening of technology (Green IT) and finding ways to green by technology (Green IS). The extant literature on Green IT/IS has also developed to recognise the role IT/IS can play in supporting organisation’s environmental sustainability objectives. There is a demand for research and case studies to inform the development of best practices and identification of innovative measures to combat climate change through IT/IS. Universities represent organisations that are large technology users. This this case study analyses the Green IT/IS practices of a University through two academic frameworks: G-readiness and Eco-goals. To support the demand for information in this area, this case study seeks to understand the Green IT/IS practices and capabilities of a University through the G-readiness goals and align these to eco-goals. Through this exploration a maturity benchmark is established and recommendations provided to enhance Green IT/IS activities

This survey examines some of the leading commercial Virtualisation and Thin Client technologies. Reference is made to a number of academic research sources and to prominent industry specialists and commentators. A basic virtualisation Laboratory model is assembled to demonstrate fundamental Thin Client operations and to clarify potential problem areas

Greening IT : How greener it can form a solid base for a low-carbon society

272 p.Libro ElectrónicoInformation Technology is responsible for approximately 2% of the world's emission of greenhouse gases. The IT sector itself contributes to these greenhouse gas emissions, through its massive consumption of energy - and therefore continuously exacerbates the problem. At the same time, however, the IT industry can provide the technological solutions we need to optimise resource use, save energy and reduce greenhouse gas emissions. We call this Greening IT. This book looks into the great potential of greening society with IT - i.e. the potential of IT in transforming our societies into Low-Carbon societies. The book is the result of an internationally collaborative effort by a number of opinion leaders in the field of Greening IT. Tomado de http://www.amazon.com/gp/product/8791936020The Greening of IT is a symptom of a much larger challenge for humankind - transitioning from economic childhood into maturity. Despite the emergence of large regional alliances such as the EC, humankind remains incredibly fragmented; and yet the need for global climate and energy policies is pressing. IT offers tantalizing technical solutions to our emissions and growth dilemma: it can grow greener and help with the greening of other industries. This book explores this potential.AcknowledgementsDisclosure1 Prologue2 Our Tools Will Not Save Us This Time - by Laurent Liscia3 Climate Change and the Low Carbon Society - by Irene N.

Data Center Green Performance Measurement: State of the Art and Open Research Challenges

Data centers (DC/DCs) are indispensable elements of information systems. The increase in information technology service demand drives their worldwide grow in number, size and energy consumption. In the light of depleting raw natural resources and climate change induced by greenhouse gases (GHG) the environmental impacts of DCs have received particular attention. This paper reviews literature to highlight major issues that contribute to DCs ecologic sustainability, and explores the state of the art of green performance indicators (GPIs) to assess DCs environmental performance, in particular the energy, GHG and resource efficiency. Afterwards, the identified GPIs are classified and clustered to construct a green performance measurement system. Furthermore, the paper generates insights in relation to the recognition and application of proposed GPIs in practice through 13 questionnaires and two expert interviews. Thus, the paper provides academics and practitioners with the body of knowledge on DC green performance measurement, and moreover formulates open research challenges

Measurement of Energy Consumption of ICT Solutions Applied for Improving Energy Efficiency in Transport Sector

In the recent times, energy efficiency is an important field in manufacturing and transport sector, mainly due to ecological concerns and ever rising energy prices. Rapid increase in population is causing an energy overload and rise in level of Green House Gases (GHG), which should be dealt in an energy efficient and smart way. We are liv-ing in the information age, where broadband, internet and data center saturates the world of information. Information is available through all possible mediums, wired as well as wireless. Data transmission and data storing capacities of Information and Communication Technologies (ICT) infrastructures are growing very fast and continu-ously, which are helpful in developing effectual Intelligent Transport System (ITS) and will reduce various social and environmental problems caused by modern transportation. This thesis is based on evaluating the share of energy consumed by ICT in a smart city for the transportation domain. The use of ICT in the transport sector has been increased for the last few decades where ICT is helping on developing more energy efficient sys-tems. Due to extensive ICT equipment used, it is necessary to calculate the energy con-sumption of the ICT equipment itself to identify, how much energy has been reduced in the consumption. Consecutively, calculating the energy consumption and estimating how much energy efficiency is achieved with ICT equipment in the infrastructure. However, there is not a single widely approved methodology that can be implemented for appropriately estimating the energy consumption of the ICT infrastructure, which can yield correct and fruitful results. Apart from the methodologies followed for the work conducted, this thesis will also look into a number of other energy measurement methodologies. All the entities involved in power consumption for ICT solutions in transportation are calculated and justified with visualizing the data collected. These results will help in evaluating the energy expenditure of the implemented systems and it will be possible to compare these values with the energy savings that are obtained. Finally, a JAVA based energy calculator is developed to accompany the test results collected
