Benchmarking Big Data Technologies for Energy Procurement Efficiency
The electrical power industry is undergoing radical change due to the push for renewable energy that makes energy supply less predictable. Smart meters along with analytics software can grant insights into customer-specific consumption and thereby enable a better match between the demand and supply side for an electric utility. However, the vast amount of allocatable smart metering data and complexity of analytics pose challenges to database system. We address the implementation of an analytics ap-proach to optimize customer portfolios, eventually preventing excess energy procurement. Using real-world and simulated data, we test the suitability of big data approaches as well as traditional relational database technology. Furthermore, we present solutions based on big data platforms and demonstrate their cost effectiveness and performance. Our findings suggest economic feasibility of big data solutions for large utilities. Small and medium-sized utilities are advised to invest in more cost-effective solutions such as cluster-based systems
Benchmarking Utility Clean Energy Deployment: 2016
Benchmarking Utility Clean Energy Deployment: 2016 provides a window into how the global transition toward clean energy is playing out in the U.S. electric power sector. Specifically, it reveals the extent to which 30 of the largest U.S. investor-owned electric utility holding companies are increasingly deploying clean energy resources to meet customer needs.Benchmarking these companies provides an opportunity for transparent reporting and analysis of important industry trends. It fills a knowledge gap by offering utilities, regulators, investors, policymakers and other stakeholders consistent and comparable information on which to base their decisions. And it provides perspective on which utilities are best positioned in a shifting policy landscape, including likely implementation of the U.S. EPA's Clean Power Plan aimed at reducing carbon pollution from power plants

Energy Information Systems: From the Basement to the Boardroom
A significant buildings energy reduction opportunity exists in the office sector, given that this market segment typically is an early adopter of new technology. There is a rising trend towards smart and connected offices through the internet of things (IoT) that provides new opportunities for operational efficiency and environmental sustainability practices. Leading commercial real estate companies have begun to shift from individual building automation systems (BAS) to partially integrated and automated systems such as energy information systems (EIS). In both the United States and India, organizations are seeking operational excellence, enhanced tenant relationships, and topline growth. Hence it is imperative to engage the executives with decision-making power, by tapping into their interest in sustainability, corporate social responsibility, and innovation. This expansion of interest can enable data-driven decisions, strong energy investments, and deeper energy benefits, and would drive innovation in this field. However, none of this would be possible without robust, consistent building energy information to provide visibility across all the levels of decision making, i.e. from the basement where the facilities staff take operational action to the boardroom where the executives make investment decisions.
Price, security, and ease of use remain barriers to the adoption and pervasive use of promising EIS technologies in commercial office buildings. We believe that these barriers can be addressed through the development of ready, simplified, consistent, commercially available, low-cost EIS-in-a-box packages, that have a pre-defined set of hardware components and software features and functionality that are pertinent to a particular building sector. These simplified, sector-specific EIS packages can help to obviate the need for customization, and enhance ease of use, thereby enabling scale-up, in order to facilitate building energy savings. The EIS-in-a-box are adaptable in both U.S. and Indian office buildings, and potentially beyond these two countries
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
Shipbuilding 4.0 Index Approaching Supply Chain
The shipbuilding industry shows a special interest in adapting to the changes proposed by
the industry 4.0. This article bets on the development of an index that indicates the current situation
considering that supply chain is a key factor in any type of change, and at the same time it serves as a
control tool in the implementation of improvements. The proposed indices provide a first definition
of the paradigm or paradigms that best fit the supply chain in order to improve its sustainability and
a second definition, regarding the key enabling technologies for Industry 4.0. The values obtained
put shipbuilding on the road to industry 4.0 while suggesting categorized planning of technologies
Energy efficiency interventions in UK higher education institutions
This paper provides an insight into energy efficiency interventions studies, focusing on issues arising in UK higher education institutions (HEIs) in particular Based on a review of the context for energy efficiency and carbon reduction programmes in the UK and the trends in higher education sector, existing external and internal policies and initiatives and their relevant issues are extensively discussed To explore the efficacy of some internal intervention strategies, such as technical, non-technical and management interventions, a survey was conducted among UK higher education institutions between February and April 2008 Consultation responses show that there are a relatively high percentage of institutions (83%) that have embarked on both technical and non-technical initiatives, which is a demonstration to the joined-up approach in such area Major barriers for intervention studies are also identified, including lack of methodology, non-clarity of energy demand and consumption issues, difficulty in establishing assessment boundaries, problems with regards to indices and their effectiveness and so on Besides establishing clear targets for carbon reductions within the sector, it is concluded that it is important to develop systems for effectively measuring and evaluating the Impact of different policies, regulations and schemes in the future as the first step to explore (C) 2010 Elsevier Ltd All rights reserve
Accelerating U.S. Clean Energy Deployment: Investor Policy Priorities
International investment to mitigate climate change is far below levels needed to reach the two-degree target. The International Energy Agency estimates that an average of an additional 24 trillion in assets issued the Global Investor Statement on Climate Change, calling on governments to create an ambitious global agreement that includes a meaningful price on carbon -- the "Clean Trillion."This paper connects the Clean Trillion goal to the current United States climate and clean energy policy framework, which is a mixture of federal, state, and local initiatives. The paper outlines the 2015 U.S. policy priorities of the Policy Working Group of the Investor Network on Climate Risk (INCR), a network of more than 110 institutional investors primarily based in the U.S., focused on investment risks and opportunities associated with climate change
State of the water sector report 2015
The Australian Water Association and Deloitte are pleased to present the State of the Water Sector Report 2015. The Report is the only one of its kind, reporting on the trends and insights of water sector professionals about their own industry.
The survey results reveal attitudes and behaviours relating to a range of topics affecting the industry. This year marks the fifth year that the survey has been run and, as such, a summary of trends across the five years has been included in this year’s report.
Trends observed over the last five years
operational efficiency first emerged as an issue affecting the water sector in 2013, due to growing concerns about the need to control costs and demonstrate value for money, both within the sector itself and for customers. This rose to become the primary issue and area of concern in 2014 as operational costs continued to rise and new capital investment costs were being passed on to customers. In 2015 operational efficiency remains the second biggest issue for the industry, with efficiencies still to be gained through asset management, process improvement and works management and systems improvement.
Skills shortages, and talent attraction and retention were of significant concern when the survey commenced five years ago, with the issue of ageing workforces in particular seen by many as a looming threat for the industry. However, in more recent years these concerns have almost halved due to a reduction in demand for additional staff and the greater availability of skilled labour, given construction activity in the mining industry has eased.
Unconventional gas came onto the industry’s radar in 2012. last year, 70% of respondents stated that they believed unconventional gas had a significant to moderate effect on the overall management of ground- or surface water. In 2015, 55% of respondents stated that produced water from unconventional gas activities can be treated to a suitable quality for irrigation and other purposes, nevertheless highlighting some concerns in relation to the oil and gas sector impact.
Although climate change was identified by 86% of respondents last year as posing a significant or moderate risk to sustainable management of water, sustainability is rated as less important than in previous years, with it being ranked as one of the top issues for the sector in 2011. This may be due to broader changes in community sentiment regarding environmental issues, and more benign weather conditions. While the sector believed security of supply was being managed well, climate change, as well as population growth, is viewed as one of the greatest challenges over the next five years.
from a price and regulatory perspective, satisfaction with the role of economic regulators continues to increase slowly, and an increasing proportion of respondents support regulators making deterministic decisions on prices, rather than just monitoring prices. However, a price monitoring role is still favoured by more than three times as many respondents as deterministic pricing.
