    Challenges for ‘Green IT’ in the Scottish ADM industry

    Our research reports specifically on the challenges and behaviours towards ‘Green IT’ experienced within one complex industry. We adopt a theoretical stance based upon Unified Theory of Acceptance and Use of Technology (UTAUT) to formulate an outline ‘Green IT’ agenda. We draw on historical thinking which underpins UTAUT, which can be traced back to the theory of reasoned action (TRA) and the frequently adopted technology acceptance model (TAM). Recent research on the business case for a green IT strategy identifies benefits to an enterprise’s revenue and/or cost rather than just its image making. In this respect, empirical evidence was collected and analysed from the Aerospace, Defence and Marine (ADM) industry in Scotland which includes over 800 companies employing nearly 40,000 staff which creates Gross Value Adding to the Scottish economy of around £2 billion. Data collection involved an on-line based semi structured questionnaire to all 180 Aerospace and Defence organisations using the Scottish Enterprise Database. Our findings suggest a need to develop unified measurements to evaluate green IT progress. Specifically, these should include a metric capable of measuring IT companies’ net environmental activism, assessing not only the impact of changes but also on the operations and products of their clients

    The cost of virtue : reward as well as feedback are required to reduce user ICT power consumption

    This work was partly supported by the IU-AC project, funded by grant EP/J016756/1 from the Engineering and Physical Sciences Research Council (EPSRC).We show that students in a school lab environment will change their behaviour to be more energy efficient, when appropriate incentives are in place, and when measurement-based, real-time feedback about their energy usage is provided. Rewards incentivise `non-green' users to be `green' as well as encouraging those users who already claim to be `green'. Measurement-based feedback improves user energy awareness and helps users to explore and adjust their use of computers to become `greener', but is not sufficient by itself. In our measurements, weekly mean group energy use as a whole reduced by up to 16%; and weekly individual user energy consumption reduced by up to 56% during active use. The findings are drawn from our longitudinal study that involved 83 Computer Science students; lasted 48 weeks across 2 academic years; monitored a total of 26778 hours of active computer use; collected approximately 2TB of raw data.Publisher PD

    Computing laboratory sustainability & utilization: initiatives for a greener education

    Get PDF
    Environmental, social and economic sustainability has been a recent focus of academia and industry to further invest in the future and lower operating costs. In this thesis, various emerging techniques are applied in an academic laboratory environment to record, analyze and project green IT initiatives. Student utilization metrics are evaluated to observe typical computing operation during a normal academic quarter. CPU load, network usage, power consumption, and room temperature are analyzed. Sustainable power and virtualization practices are recommended based on projections and assessments of current and recommended configurations. The findings of this study can be used across an academic environment to further reduce energy usage and meet the objectives of the Institute\u27s goals towards a green and sustainable environment

    Will Broadband Networks Make the World Greener? Evaluating Pros and Cons of Broadband Development

    Get PDF
    The environmental issue has generally received much attention from the public for decades, especially as a result of heavy industry - electrical energy, oil and gas, mining, steel and metals. Recently, attention has been paid to Information and Communication Technology (ICT) and its effect on the knowledge and related industries. Broadband, both fixed and mobile, is not an exception. Even though it has been recognized as a factor that has contributed to social and economic development, anegative effect can also be seen in particular regarding the environment. This paper provides a review of how government policy, in particular by the EU and Japan, are moving towards the transition to sustainability by utilizing ICT, as well as an evaluation of the pros and cons of broadband development. There are many complex effects on sustainability due to ICT. Since ICT can have environmental effects both as enabling energy efficiency and causing rebound effects, the policies should respond to both direct and indirect effects. To facilitate policy analysis and recommendations, this paper categorizes ICT impacts by five orders of aggregation. These five orders of aggregation may contribute both positively and negatively to sustainability, and each level will need targeted policies. The five orders of aggregation suggest a comprehensive and long term view of policy development, encompassing even policies that seek to improve the quality of decision making in our societies, by utilizing ICTs.broadband, sustainable development, green ICT.

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

    Get PDF
    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.
