    Renewable energy can become the major energy supply option in low-carbon energy economies. Disruptive transformations in all energy systems are necessary for tapping widely available renewable energy resources. Organizing the energy transition from non-sustainable to renewable energy is often described as the major challenge of the first half of the 21st century. Technological innovation, the economy (costs and prices) and policies have to be aligned to achieve full renewable energy potentials, and barriers impeding that growth need to be removed. These issues are also covered by IPCC's special report on renewable energy and climate change to be completed in 2010. This article focuses on the interrelations among the drivers. It clarifies definitions of costs and prices, and of barriers. After reviewing how the third and fourth assessment reports of IPCC cover mitigation potentials and commenting on definitions of renewable energy potentials in the literature, we propose a consistent set of potentials of renewable energy supplies.

  6. California renewable energy policy and implementation issues: An overview of recent regulatory and legislative action

    Energy Technology Data Exchange (ETDEWEB)

    Wiser, R.; Pickle, S.; Goldman, C.

    1996-09-01

    This paper has three primary goals: (1) to provide a brief account of recent events in California renewables policy; (2) to outline the California State Legislature`s ultimate decision on renewable energy policy; and (3) to aid other states in their efforts with renewables policy by summarizing some of the key implementation issues and political conflicts that may occur when crafting some of the potential threats and opportunities that electricity restructuring presents to the development of renewable energy. We then outline the renewables policy debate in California since the California Public Utility Commission`s ``Blue Book``, including both regulatory and legislative developments. We also provide some insight into the minimum renewables purchase requirement (MRPR) versus surcharge-based renewables policy debate in California. Finally, we identify and discuss key renewables policy implementation issues that have driven the dialogue and recent decisions in California`s renewables policy.

    Complementarity between PDA and CDA, by HU Zhuanglin, p. 3 Following a brief review of the development of positive discourse analysis(PDA) and critical discourse analysis (CDA), the paper argues for the point that the reason for James Martin to develop PDA is by no means to replace CDA with PDA, but to emphasize the complementarity between the two. This can be proved by his discussion on the relations between CDA and PDA, CDA realis and CDA irrealis, deconstruction and construction, ideational meaning and interpersonal meaning, bad news and good news, etc. Finally, the paper suggests the principle of seeking truth from facts in collecting data and doing analysis.

    Rapport Orientation of Mitigators and Their Interpersonal Pragnmtic Functions by RAN Yongping, p. 4 This paper studies the pragmatic roles of mitigatiors or mitigating devices within interpersonal relations. It holds that language use is constrained by pragmatic motivations, such as to reduce the directive force of an utterance or increase its acceptance so as to better manage interpersonal relations, this is considered the rapport orientation for the adoption of such mitigators of politeness markers, terms of address, hedges and supportive utterances. Thus, mitigation facilitates the management of interpersonal relations in interaction.

    Property Dualism and Poetic Imagery, by CHEN Daliang, p. 7 Property dualism widely accepted by scholars is Very influential in philosophy of mind. This paper, a tentative research on poetic imagery from this perspective, is intended to explore the feasible interface between two distinctive academic fields. The author argues that property dualism is closely related to the constituents of poetic imagery, image schemas can account for its generative mechanism and the intentionality theory can possess interpretative power in examining the meaning of poetic imagery. The research findings show that an poetic image consists of dual properties with one substance, the generative mechanism is the outcome of interaction of mind and body by means of various image schemas, and the meaning of poetic imagery is directed to the language reality through the intentionality.

  20. Issues, Challenges, Causes, Impacts and Utilization of Renewable Energy Sources - Grid Integration

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available The renewable energy sources have increased significantly due to environmental issues and fossil fuels elevated cost. Integration of renewable energy sources to utility grid depends on the scale of power generation. Large scale power generations are connected to transmission systems where as small scale distributed power generation is connected to distribution systems. There are certain challenges in the integration of both types of systems directly. Due to this, wind energy has gained a lot of investments from all over the world. However, due to the wind speed‘s uncertain behavior it is difficult to obtain good quality power, since wind speed fluctuations reflect on the voltage and active power output of the electric machine connected to the wind turbine. Solar penetration also changes the voltage profile and frequency response of the system and affects the transmission and distribution systems of utility grid. This paper presents a review in the issues, challenges, causes, impacts and utilization of renewable energy sources (RES - Grid Integration.

    The total costs and impacts of expanding energy use in China will depend, in part, on a number of important factors, an understanding of which is vital for China's policy-makers. These issues include the additional environmental and public health impacts associated with energy use, the economic costs of infrastructure expansion to meet growing energy needs, and the potential role that renewable energy technologies could play if pushed hard in China's energy future. This short report summarizes major trends and issues in each of these three areas.

  2. Transmission pricing and renewables: Issues, options, and recommendations

    1997-05-01

    Open access to the transmission system, if provided at reasonable costs, should open new electricity markets for high-quality renewable resources that are located far from load centers. Several factors will affect the cost of transmission service, including the type of transmission pricing system implemented and the specific attributes of renewable energy. One crucial variable in the transmission cost equation is a generator`s capacity factor. This factor is important for intermittent renewables such as wind and solar, because it can increase transmission costs several fold due to the traditional use of take-or-pay, capacity-based transmission access charges. This report argues that such a charge is demonstrably unfair to renewable generators. It puts them at an economic disadvantage that will lead to an undersupply of renewable energy compared with the least-cost mix of generation technologies. The authors argue that congestion charges must first be separated from the access charges that cover the fixed cost of the network before one can design an efficient tariff. They then show that, in a competitive market with a separate charge for congestion, a take-or-pay capacity-based access charge used to cover system fixed costs cannot be justified on the basis of peak-load pricing. An energy-based access charge, on the other hand, is fair to intermittent generators as well as to the usual spectrum of peak and base-load technologies. This report also reviews other specific characteristics of renewables that can affect the cost of transmission, and evaluates the potential impact on renewables of several transmission pricing schemes, including postage-stamp rates, megawatt-mile pricing, congestion pricing, and the Federal Energy Regulatory Commission`s {open_quotes}point-to-point{close_quotes} transmission tariffs.

    Renewables are heavily involved in power generation, as an essential component for today’s energy paradigm. Energy structure—both national and international—has been undergoing significant changes over the past few decades. For instance, in Denmark, power generation is shifting from fossil......-fuel-based to renewable-based in terms of energy sources, from centralized to decentralized in terms of architectures, and from sole to miscellaneous in terms of energy varieties [1]. In this energy evolution, the power electronic technology plays an enabling role in the integration and advancements of renewables......—such as wind turbine, photovoltaics, fuel cells, and other emerging energy systems. At the same time, various control strategies are necessary to guide the energy integration (i.e., to enhance the energy transition), and on the other hand, to flexibly, reliably, and efficiently utilize the energy.

    In 2020, some leading EU energy and climate policies will expire. At present, the EU and its Member States are discussing the design of a post-2020 policy portfolio. In a discussion paper commissioned by the European Copper Institute, Ecofys shows that an EU-wide renewable energy target is a necessary part of a 2030 portfolio. The paper analyses, in detail, two realistic policy portfolio options for renewable energy, target-setting in particular: one 'decarbonisation-only' EU target with voluntary national targets for renewable energy, and one that includes an EU-wide renewable energy target, broken down into binding national targets. The analysis shows that the latter option, when supported by appropriate and improved EU and Member States' policies and measures, is most suitable in facilitating a European low-carbon economy.

  11. Integrating Variable Renewable Energy into the Grid: Key Issues, Greening the Grid (Spanish Version)

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    This is the Spanish version of 'Greening the Grid - Integrating Variable Renewable Energy into the Grid: Key Issues'. To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, and Planning for a High RE Future.

    California is on a path to increase utilization of renewable resources. California will need to integrate approximately 30,000 megawatts (MW) of new renewable generation in the next 20 years. Renewable resources are typically located in remote locations, not near the load centers. Nearly two/thirds or 20,000 MW of new renewable resources needed are likely to be delivered to Los Angeles Basin transmission gateways. Integration of renewable resources requires interconnection to the power grid, expansion of the transmission system capability between the backbone power grid and transmission gateways, and increase in delivery capacity from transmission gateways to the local load centers. To scope the transmission, operations, and reliability issues for renewables integration, this research focused on the Los Angeles Basin Area transmission gateways where most of new renewables are likely. Necessary actions for successful renewables integration include: (1) Expand Los Angeles Basin Area transmission gateway and nomogram limits by 10,000 to 20,000 MW; (2) Upgrade local transmission network for deliverability to load centers; (3) Secure additional storage, demand management, automatic load control, dynamic pricing, and other resources that meet regulation and ramping needed in real time operations; (4) Enhance local voltage support; and (5) Expand deliverability from Los Angeles to San Diego and Northern California.

    This paper discusses the technical potential for hydrogen used as an energy storage medium to couple time-dependent renewable energy into time-dependent electric utility loads. This analysis will provide estimates of regional and national opportunities for hydrogen production, storage and conversion, based on current and near-term leading renewable energy and hydrogen production and storage technologies. Appropriate renewable technologies, wind, photovoltaics and solar thermal, are matched to their most viable regional resources. The renewables are assumed to produce electricity which will be instantaneously used by the local utility to meet its loads; any excess electricity will be used to produce hydrogen electrolytically and stored for later use. Results are derived based on a range of assumptions of renewable power plant capacity and fraction of regional electric load to be met (e.g., the amount of hydrogen storage required to meet the Northwest region`s top 10% of electric load). For each renewable technology national and regional totals will be developed for maximum hydrogen production per year and ranges of hydrogen storage capacity needed in each year (hydroelectric case excluded). The sensitivity of the answers to the fraction of peak load to be served and the land area dedicated for renewable resources are investigated. These analyses can serve as a starting point for projecting the market opportunity for hydrogen storage and distribution technologies. Sensitivities will be performed for hydrogen production, conversion. and storage efficiencies representing current and near-term hydrogen technologies.

    Miller, M.; Cox, S.

    2014-05-01

    This CERI report aims to provide an introductory overview of key regulatory issues associated with the deployment of renewable energy -- particularly variable renewable energy (VRE) sources such wind and solar power. The report draws upon the research and experiences from various international contexts, and identifies key ideas that have emerged from the growing body of VRE deployment experience and regulatory knowledge. The report assumes basic familiarity with regulatory concepts, and although it is not written for a technical audience, directs the reader to further reading when available. VRE deployment generates various regulatory issues: substantive, procedural, and public interest issues, and the report aims to provide an empirical and technical grounding for all three types of questions as appropriate.

    Continuous-flow nanocatalysis based on metal nanoparticle catalyst-anchored flow reactors has recently provided an excellent platform for effective chemical manufacturing. However, there has been limited progress in porous structure design and recycling systems for metal nanoparticle-anchored flow reactors to create more efficient and sustainable catalytic processes. In this study, traditional paper is used for a highly efficient, recyclable, and even renewable flow reactor by tailoring the ultrastructures of wood pulp. The "paper reactor" offers hierarchically interconnected micro- and nanoscale pores, which can act as convective-flow and rapid-diffusion channels, respectively, for efficient access of reactants to metal nanoparticle catalysts. In continuous-flow, aqueous, room-temperature catalytic reduction of 4-nitrophenol to 4-aminophenol, a gold nanoparticle (AuNP)-anchored paper reactor with hierarchical micro/nanopores provided higher reaction efficiency than state-of-the-art AuNP-anchored flow reactors. Inspired by traditional paper materials, successful recycling and renewal of AuNP-anchored paper reactors were also demonstrated while high reaction efficiency was maintained. © 2017 The Authors.

    2015-05-01

    To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, Planning for a High RE Future.

  1. Regulatory policy issues and the Clean Air Act: Issues and papers from the state implementation workshops

    Energy Technology Data Exchange (ETDEWEB)

    Rose, K. [ed.; Burns, R.E.

    1993-07-01

    The National Regulatory Research Institute (NRRI), with funding from the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE), conducted four regional workshops` on state public utility commission implementation of the Clean Air Act Amendments of 1990 (CAAA). The workshops had four objectives: (1) to discuss key issues and concerns on CAAA implementation, (2) to encourage a discussion among states on issues of common interests, (3) to attempt to reach consensus, where possible, on key issues, and (4) to provide the workshop participants with information and materials to assist in developing state rules, orders, and procedures. From the federal perspective, a primary goal was to ensure that workshop participants return to their states with a comprehensive background and understanding of how state commission actions may affect implementation of the CAAA and to be able to provide guidance to their jurisdictional utilities. It was hoped that this would reduce some of the uncertainty utilities face and assist in the development of an efficient allowance market. This report is divided into two main sections. In Section II, eleven principal issues are identified and discussed. These issues were chosen because they were either the most frequently discussed or they were related to the questions asked in response to the speakers` presentations. This section does not cover all the issues relevant to state implementation nor all the issues discussed at the workshops; rather, Section II is intended to provide an overview of the,planning, ratemaking, and multistate issues. Part III is a series of workshop papers presented by some of the speakers. Individual papers have been cataloged separately.

    Rwanda is an exception among low-income developing countries in that it has given high priority to environmental and natural resource management (NRM) issues. The paper describes A.I.D.'s support for these efforts and explores the possibility of integrating them into agricultural and rural development programs in Rwanda and elsewhere in sub-Saharan Africa. Major findings include: Government support is a prerequisite to developing the long-term strategies needed to address specific NRM issues; Developing appropriate NRM technologies is a complex undertaking requiring site-specific applied research; Donors should appreciate the difficulty host countries face in balancing NRM with development, conservation, and equity objectives; USAID/Rwanda assistance has covered a wide range of NRM activities, many of them complementary to those of other donors, some part of a coordinated multi-donor effort; and The Mission's program includes several innovative and potentially replicable approaches, including the promotion of ecotourism in conjunction with wildlife conservation and park management, and agroforestry and fish farming to conserve soil and water resources while increasing farm productivity. Since such activities often require costly investments and yield their ecological and economic benefits only in the long term, a broader framework than simple cost-benefit analysis might be needed in attempting to incorporate them into USAID/Rwanda's agricultural and rural development portfolio.

  8. Project Independence: Construction of an Integrated Biorefinery for Production of Renewable Biofuels at an Existing Pulp and Paper Mill

    Energy Technology Data Exchange (ETDEWEB)

    Freeman, Douglas

    2012-06-01

    Project Independence proposed to construct a demonstration biomass-to-liquids (BTL) biorefinery in Wisconsin Rapids, isconsin. The biorefinery was to be co-located at the existing pulp and paper mill, NewPage Wisconsin System Incorporated’s Wisconsin Rapids Mill, and when in full operation would both generate renewable energy for Wisconsin Rapids Mill and produce liquid fuels from abundant and renewable lignocellulosic biomass. The biorefinery would serve to validate the thermochemical pathway and economic models for BTL production using forest residuals and wood waste, providing a basis for proliferating BTL conversion technologies throughout the United States. It was a project goal to create a compelling new business model for the pulp and paper industry, and support the nation’s goal for increasing renewable fuels production and reducing its dependence on foreign oil. NewPage Corporation planned to replicate this facility at other NewPage Corporation mills after this first demonstration scale plant was operational and had proven technical and economic feasibility. An overview of the process begins with biomass being harvested, sized, conditioned and fed into a ThermoChem Recovery International (TRI) steam reformer where it is converted to high quality synthetic gas (syngas). The syngas is then cleaned, compressed, scrubbed, polished and fed into the Fischer-Tropsch (F-T) catalytic reactors where the gas is converted into two, sulfur-free, clean crude products which will be marketed as revenue generating streams. Additionally, the Fischer-Tropsch products could be upgraded for use in automotive, aviation and chemical industries as valuable products, if desired. As the Project Independence project set out to prove forest products could be used to commercially produce biofuels, they planned to address and mitigate issues as they arose. In the early days of the Project Independence project, the plant was sized to process 500 dry tons of biomass per day but would

    2013-01-15

    Around 70 million Nigerians have no access to grid electricity. Reliable night-time lighting for households, for refrigeration, and affordable power for businesses would change many lives, and renewable energy has the potential to do this. But for solar power, hydropower and wind energy to be made available on a significant scale, government policy needs to change. Affordable loans to finance development and market growth for a range of installations, including solar thermal power, which shows major long-term potential for northern Nigeria, are essential. And government and non-government organisations must implement a strategy to increase understanding among individual consumers, business people and policymakers about the benefits of renewable energy.

    The aging of nuclear power plants is one of the most important issues facing the nuclear industry worldwide. Aging encompasses as forms of degradation to nuclear power plant components, systems, and structures that result from exposure to environmental conditions or from operational stresses. Both the degradation from aging and actions taken to address the aging, such as increased maintenance and testing, can significantly impact human performance in the plant. Research into the causes and effects of aging as obtained through the assessment of operating experience and testing have raised questions regarding the adequacy of existing industry standards for addressing the concerns raised by this research. This paper discusses these issues, with particular emphasis in the area of equipment qualification and human performance.

    Renewable energy production may offer advantages to human health by way of less pollution and fewer climate-change associated ill-health effects. Limited data suggests that renewable energy will also offer benefits to workers in the form of reduced occupational injury, illness and deaths. However, studies of worker safety and health in the industry are limited. The Mountain and Plains Education and Research Center (MAP ERC) Energy Summit held in April 2011 explored issues concerning worker health and safety in the renewable energy industry. The limited information on hazards of working in the renewable energy industry emphasizes the need for further research. Two basic approaches to guiding both prevention and future research should include: (1) applying lessons learned from other fields of occupational safety and health, particularly the extractive energy industry; and (2) utilizing knowledge of occupational hazards of specific materials and processes used in the renewable energy industry.

    Full Text Available The world is fast becoming a global village due to the increasing daily requirement of energy by all population across the world while the earth in its form cannot change. The need for energy and its related services to satisfy human social and economic development, welfare and health is increasing. Returning to renewables to help mitigate climate change is an excellent approach which needs to be sustainable in order to meet energy demand of future generations. The study reviewed the opportunities associated with renewable energy sources which includes: Energy Security, Energy Access, Social and Economic development, Climate Change Mitigation, and reduction of environmental and health impacts. Despite these opportunities, there are challenges that hinder the sustainability of renewable energy sources towards climate change mitigation. These challenges include Market failures, lack of information, access to raw materials for future renewable resource deployment, and our daily carbon footprint. The study suggested some measures and policy recommendations which when considered would help achieve the goal of renewable energy thus to reduce emissions, mitigate climate change and provide a clean environment as well as clean energy for all and future generations.

    1979-12-01

    Load-management-technology options are commercially available and may be desirable in many utility-service areas. Energy-conservation and renewable-energy-supply technologies are also cost-effective in many applications and, where installed, may reduce the effectiveness and attractiveness of load-management options. Recent energy legislation has not addressed these competitive interrelationships; future legislation is unlikely to do so unless a coordinated task-force effort among relevant DOE offices is pursued to derive strategic technology and policy recommendations on this issue. R and D strategies should help formulate these recommendations.

  4. Resolving issues with environmental impact assessment of marine renewable energy installations

    Directory of Open Access Journals (Sweden)

    Ilya M. D. Maclean

    2014-12-01

    Full Text Available Growing concerns about climate change and energy security have fueled a rapid increase in the development of marine renewable energy installations (MREIs. The potential ecological consequences of increased use of these devices emphasizes the need for high quality environmental impact assessment (EIA. We demonstrate that these processes are hampered severely, primarily because ambiguities in the legislation and lack of clear implementation guidance are such that they do not ensure robust assessment of the significance of impacts and cumulative effects. We highlight why the regulatory framework leads to conceptual ambiguities and propose changes which, for the most part, do not require major adjustments to standard practice. We emphasize the importance of determining the degree of confidence in impacts to permit the likelihood as well as magnitude of impacts to be quantified and propose ways in which assessment of population-level impacts could be incorporated into the EIA process. Overall, however, we argue that, instead of trying to ascertain which particular developments are responsible for tipping an already heavily degraded marine environment into an undesirable state, emphasis should be placed on better strategic assessment.

  9. CALL FOR PAPERS: Special issue: One hundred years of PVI, the Fuchs Painlevé equation

    Science.gov (United States)

    Clarkson, P. A.; Joshi, N.; Mazzocco, M.; Nijhoff, F. W.; Noumi, M.

    2005-10-01

    This is a call for contributions to a special issue of Journal of Physics A: Mathematical and General entitled `One hundred years of Painlevé VI, the Fuchs Painlevé equation'. The motivation behind this special issue is to celebrate the centenary of the discovery of this famous differential equation. The Editorial Board has invited P A Clarkson, N Joshi, M Mazzocco, F W Nijhoff and M Noumi to serve as Guest Editors for the issue. The nonlinear ordinary differential equation, which is nowadays known as the Painlevé VI (PVI) equation, is one of the most important differential equations in mathematical physics. It was discovered 100 years ago by Richard Fuchs (son of the famous mathematician Lazarus Fuchs) and reported for the first time in Comptes Rendus de l'Academie des Sciences Paris 141 555 8 (1905). Gambier, in his seminal paper of 1906, included this equation as the top equation in the list of what are now known as the six Painlevé transcendental equations. The Painlevé list emerged from the work on the classification of all ordinary second-order differential equations whose general solution are `uniform', in the sense that there are no movable (i.e. as a function of the initial data) singularities (meaning branch points) worse than poles. The latter is known as the Painlevé property. As the top equation in the Painlevé list of transcendental equations, the importance of PVI can be appreciated by recognizing that this is a universal differential equation, which is the most general (in terms of number of free parameters) of the known second order ODEs defining nonlinear special functions. As such, parallels can be drawn between the role played by PVI transcendents in the nonlinear case and the hypergeometric functions at the linear level. In fact, the monograph From Gauss to Painlevé by K Iwasaki, H Kimura, S Shimomura and M Yoshida (Vieweg, 1991), draws very clearly the line stretching over more than 150 years of special function theory in which PVI is

    In the summer of 2006 the Green Institute started the study for the RockTenn paper mill that would evaluate the economics and supply chain reliability of wood waste and other clean biomass as a fuel for the facility. The Green Institute obtained sponsorship from a broad coalition representing the community and the project team included other consultants and university researchers specializing in biomass issues. The final product from the project was a report to: 1) assess the availability of clean biomass fuel for use at the Rock-Tenn site; 2) roughly estimate costs at various annual usage quantities; and 3) develop the building blocks for a supply chain procurement plan. The initial report was completed and public presentations on the results were completed in spring of 2007.

  13. CALL FOR PAPERS: Special Issue on `Singular Interactions in Quantum Mechanics: Solvable Models'

    Science.gov (United States)

    Dell'Antonio, G.; Exner, P.; Geyler, V.

    2004-07-01

    This is a call for contributions to a special issue of Journal of Physics A: Mathematical and General entitled `Singular Interactions in Quantum Mechanics: Solvable Models'. This issue should be a repository for high quality original work. We are interested in having the topic interpreted broadly, that is, to include contributions dealing with point-interaction models, one- and many-body, quantum graphs, including graph-like structures coupling different dimensions, interactions supported by curves, manifolds, and more complicated sets, random and nonlinear couplings, etc., as well as approximations helping us to understand the meaning of singular couplings and applications of such models on different parts of quantum mechanics. We believe that when the second printing of the `bible' of the field, the book Solvable Models in Quantum Mechanics by S Albeverio, F Gesztesy, the late R Høegh-Krohn and H Holden, appears it is the right moment to review new developments in this area, with the hope of stimulating further development of these extremely useful techniques. The Editorial Board has invited G Dell'Antonio, P Exner and V Geyler to serve as Guest Editors for the special issue. Their criteria for acceptance of contributions are as follows: bullet The subject of the paper should relate to singular interactions in quantum mechanics in the sense described above. bullet Contributions will be refereed and processed according to the usual procedure of the journal. bullet Papers should be original; reviews of a work published elsewhere will not be accepted. The guidelines for the preparation of contributions are as follows: bullet The DEADLINE for submission of contributions is 31 October 2004. This deadline will allow the special issue to appear in about April 2005. bullet There is a nominal page limit of 15 printed pages (approximately 9000 words) per contribution. Papers exceeding these limits may be accepted at the discretion of the Guest Editors. Further advice on

  14. Generation Capacity Investments and High Levels of Renewables. The Impact of a German Capacity Market on Northwest Europe. Discussion paper

    Ozdemir, O.; De Joode, J.; Koutstaal, P.R.; Van Hout, M. [ECN Policy Studies, Amsterdam (Netherlands)

    2013-05-15

    Presently, Northwest European centralised electricity markets are designed as 'energy-only' markets. In an energy-only market, the price received for electricity produced is set by the marginal generation unit. Potentially, the designs of these markets could leave the owners of these units with 'missing money': i.e. money that is required to recover investment cost. Further, increasing penetration of renewables could exacerbate this problem. Of all the different options available to tackle the 'missing money' problem, capacity mechanisms have attracted most of the attention in recent policy debates in Europe. This paper contributes to ongoing policy discussions by providing a quantitative analysis of the phenomena of 'missing money' and capacity mechanisms in Northwest Europe. Our analysis shows that in the case of energy-only markets with a much higher penetration of intermittent electricity sources such as wind and solar PV, the 'missing money' problem may be aggravated, because operating hours for peak and mid-merit order capacity will be considerably reduced. Furthermore, unilateral introduction of capacity mechanisms in integrated electricity markets can have considerable impacts on cross-border electricity flows and investment decisions. Stand-alone introduction of a capacity market in Germany will likely result in higher investments in Germany at the expense of lower investments outside Germany and an increase in net exports from Germany. A possible advantage of a unilateral capacity mechanism in Germany may be a reduction in super-peak prices in the larger market area. Thus, neighbouring countries may have the possibility to free ride on the increase in flexible capacity in Germany. However, this advantage is conditional and depends on sufficient availability of interconnection capacity necessary to be able to use this reserve capacity. Otherwise, security of supply might be more at risk if the German

    Full Text Available This issue completes the first ten years of Numeracy. The purpose of this introductory editorial is to review what has happened to the journal in those ten years. In the twenty issues, Numeracy’s output has been 201 papers counting the one or two editorials per issue. More than 50% of the papers are full, peer-reviewed articles, including 13 papers in two theme collections. The others are peer-reviewed notes and perspectives, editor-reviewed book reviews (15% of the total, and a column by contributing co-editor, Dorothy Wallace. The current issue marks an upswing in the number of notes, and our first discussion/reply. The number of papers per year has been increasing (e.g., 66% more in the last three years than in the first three years. The download rate has increased from about 5,000 in the first two years to 5,000 in about 40 days now. The editorial goes on to document two main outcomes. First, the journal is gaining an international reach: more than half the downloads occur outside the United States now, and the number of contributions from outside the United States has increased from 4 in the first five years to 15 in the second five years. Second, the across-the-curriculum nature of quantitative literacy is coming to the fore. The transdisciplinarity of QL is strikingly evident in this issue, which is discussed in some detail, especially how it conforms to the mission of the Association of American Colleges and Universities. The editorial ends with some results from a small ad hoc study of Google Scholar Citation Profiles. The question was, of the profiles that used “numeracy” or “quantitative literacy” as keywords, what other keywords did those profiles use, and what were the source countries? The results show that (1 QL is very much an American term, (2 there is, metaphorically, a vast and interesting numeracy ecosystem out there for Numeracy to engage and serve, and (3 as we become more global, the transdisciplinary relevance

    2006-10-01

    This is a call for contributions to a special issue of Journal of Physics A: Mathematical and General entitled `Special issue on Symmetries and Integrability of Difference Equations' as featured at the SIDE VII meeting held during July 2006 in Melbourne (http://web.maths.unsw.edu.au/%7Eschief/side/side.html). Participants at that meeting, as well as other researchers working in the field of difference equations and discrete systems, are invited to submit a research paper to this issue. This meeting was the seventh of a series of biennial meetings devoted to the study of integrable difference equations and related topics. The notion of integrability was first introduced in the 19th century in the context of classical mechanics with the definition of Liouville integrability for Hamiltonian flows. Since then, several notions of integrability have been introduced for partial and ordinary differential equations. Closely related to integrability theory is the symmetry analysis of nonlinear evolution equations. Symmetry analysis takes advantage of the Lie group structure of a given equation to study its properties. Together, integrability theory and symmetry analysis provide the main method by which nonlinear evolution equations can be solved explicitly. Difference equations, just as differential equations, are important in numerous fields of science and have a wide variety of applications in such areas as: mathematical physics, computer visualization, numerical analysis, mathematical biology, economics, combinatorics, quantum field theory, etc. It is thus crucial to develop tools to study and solve difference equations. While the theory of symmetry and integrability for differential equations is now well-established, this is not yet the case for discrete equations. The situation has undergone impressive development in recent years and has affected a broad range of fields, including the theory of special functions, quantum integrable systems, numerical analysis, cellular

    The Smart Grid Network was established in 2010 by the Danish climate and energy minister tasked with developing recommendations for future actions and initiatives that make it possible to handle up to 50% electricity from wind energy in the power system in 2020. The task of working group 3 was defined as: - An overview of the Danish research and development of smart grids and related areas; - Conducting an analysis of the research and development needs required for the introduction of a smart grid in Denmark. Based on this analysis, provide suggestions for new large research and development projects; - Provide recommendations on how the activities are best carried out taking into account innovation, economic growth and jobs. In the analysis it is explained that Denmark so far has a strong position in several elements of RD and D activities. This position will soon be threatened as several European countries have launched ambitious initiatives to strengthen the national position. The working group recommends that Denmark gives priority to Smart Grids as a national action in order to solve the challenge of technically and economically efficient integration of renewable energy. Smart Grid is a catalyst that strengthens a new green growth industry (cleantech) in Denmark. Research and development has an important role to play in this development. A common vision and roadmap must be established for research institutions, energy companies and industries related to research, development and demonstration of Smart Grid, which can maintain and expand Denmark's global leadership position. As part of this, there is a need to strengthen and market research infrastructures, which can turn Denmark into a global hub for smart grid development. There is a current need to strengthen the advanced technical and scientific research in the complexities of the power system, research on market design, user behavior and smart grid interoperability.

  2. Cooperation mechanisms of the EU renewable energy directive and flexible mechanisms of the Kyoto Protocol: comparison and lessons learnt. Working paper

    2013-07-15

    This working paper discusses similarities and differences between the cooperation mechanisms of the EU renewable energy directive (RES directive) and the flexible mechanisms of the Kyoto Protocol. The cooperation mechanisms allow the (virtual) trade of renewable energy and were introduced with the RES directive to provide Member States (MS) with greater flexibility to achieve their national targets for renewable energy sources (RES). A similar kind of flexibility is known from the flexible mechanisms of the Kyoto Protocol which aim at the cost efficient achievement of emission reduction targets. Lessons learned from the Kyoto mechanisms may allow conclusions to be drawn on the design and implementation of the renewable energy cooperation mechanisms. This paper first gives an overview of the cooperation mechanisms regarding their potential, advantages and disadvantages, barriers and preconditions. This is followed by a brief explanation of and a systematic comparison with the flexible mechanisms of the Kyoto Protocol – Joint Implementation (JI); Clean Development Mechanism (CDM); and International Emissions Trading (IET). A gamut of factors influenced the success of the Kyoto mechanisms in general and in specific national contexts. Therefore, it is not possible to directly transfer past experiences with the Kyoto mechanisms to the capability of specific nations to make use of the renewable energy cooperation mechanisms. A comparison of specific features, such as the mechanism type (transfer, project-based, support scheme), price building and specific barriers can, however, help anticipate the possible dynamics and challenges of the cooperation mechanisms. Experiences with the Kyoto mechanisms show that predictions based on supply-demand analysis were valid only to a limited extent and that specific factors such as institutional capacity constraints or legal uncertainties delayed or prevented the use of the mechanisms in some cases. Similarly, for the cooperation

    Material failure is accompanied by important heat exchange, with extremely high temperature - thousands of degrees - reached at crack tips. Such temperature may subsequently alter the mechanical properties of stressed solids, and finally facilitate their rupture. Thermal runaway weakening processes could indeed explain stick-slip motions and even be responsible for deep earthquakes. Therefore, to better understand and eventually prevent catastrophic rupture events, it appears crucial to establish an accurate energy budget of fracture propagation from a clear measure of the various energy dissipation sources. In this work, combining analytical calculations and numerical simulations, we directly relate the temperature field around a moving crack tip to the part α of mechanical energy converted into heat. Monitoring the slow crack growth in paper sheets with an infrared camera, we measure a significant fraction α = 12± 4%. Besides, we show that (self-generated) heat accumulation could weaken our samples with microfibers combustion, and lead to a fast crack/dynamic failure/ regime.

    Recent advances in the fields of organ donation and organ transplant have introduced new hope for the treatment of serious diseases. However, this promise has been accompanied by several issues. The most common issue raised is ethical implications, but in a multicultural society like Malaysia, additional concerns arise pertaining to social and religious issues. These concerns needs to be addressed as attitudes toward and acceptability of organ donation varies according to social, culture, and religion. The diverse cultural, religious, and traditional concepts pertaining to organ donation may hamper its acceptability and cause a lack of willingness to donate organs. The purpose of this article is to briefly explore the ethical issues involved in organ transplant and the various religious opinions on organ donation. It is hoped that this knowledge and understanding may benefit both health care providers and patients in a multicultural society like Malaysia.

    The aim of this work is to analyze the political, regulatory, economic and technical issues that have determined the use of primary energies for power generation in Mexico from 1965 to 2008, and its perspectives for the next 10 years, in particular the prospects of using renewable energies. In the 60's, hydro was the preferred source of energy to produce electricity for economical and technical reasons. Under the 'oil boom' in the 70s, transition to hydrocarbons resources (fuel oil) was progressive. As a result of implementing environmental policies, electricity has mainly been generated with natural gas since the early 2000.

    Oestergaard, Iben [ed.

    1998-12-31

    This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

    The Semi-Arid Land-Surface-Atmosphere Program (SALSA) is a multi-agency, multi-national research effort that seeks to evaluate the consequences of natural and human-induced environmental change in semi-arid regions. The ultimate goal of SALSA is to advance scientific understanding of the semi-arid portion of the hydrosphere-biosphere interface in order to provide reliable information for environmental decision making. SALSA approaches this goal through a program of long-term, integrated observations, process research, modeling, assessment, and information management that is sustained by cooperation among scientists and information users. In this preface to the SALSA special issue, general program background information and the critical nature of semi-arid regions is presented. A brief description of the Upper San Pedro River Basin, the initial location for focused SALSA research follows. Several overarching research objectives under which much of the interdisciplinary research contained in the special issue was undertaken are discussed. Principal methods, primary research sites and data collection used by numerous investigators during 1997-1999 are then presented. Scientists from about 20 US, five European (four French and one Dutch), and three Mexican agencies and institutions have collaborated closely to make the research leading to this special issue a reality. The SALSA Program has served as a model of interagency cooperation by breaking new ground in the approach to large scale interdisciplinary science with relatively limited resources.

    A Kuhnian approach to research assessment requires us to consider that the important scientific breakthroughs that drive scientific progress are infrequent and that the progress of science does not depend on normal research. Consequently, indicators of research performance based on the total number of papers do not accurately measure scientific progress. Similarly, those universities with the best reputations in terms of scientific progress differ widely from other universities in terms of the scale of investments made in research and in the higher concentrations of outstanding scientists present, but less so in terms of the total number of papers or citations. This study argues that indicators for the 1% high-citation tail of the citation distribution reveal the contribution of universities to the progress of science and provide quantifiable justification for the large investments in research made by elite research universities. In this tail, which follows a power low, the number of the less frequent and highly cited important breakthroughs can be predicted from the frequencies of papers in the upper part of the tail. This study quantifies the false impression of excellence produced by multinational papers, and by other types of papers that do not contribute to the progress of science. Many of these papers are concentrated in and dominate lists of highly cited papers, especially in lower-ranked universities. The h-index obscures the differences between higher- and lower-ranked universities because the proportion of h-core papers in the 1% high-citation tail is not proportional to the value of the h-index.

    This document identifies and discusses the significant issues raised by the idea of recovering useful by-products from wastes (primarily spent brine) generated during geothermal power production. The physical availability of numerous valuable materials in geothermal brines has captured the interest of geothermal resource developers and other parties ever since their presence was known. The prospects for utilizing huge volumes of highly-saline geothermal brines for electricity generation in the Imperial Valley of California have served to maintain this interest in both private sector and government circles.

    Financial Risk and Derivatives provides an excellent illustration of the links that have developed in recent years between the theory of finance on one hand and insurance economics and actuarial science on the other. Advances in contingent claims analysis and developments in the academic and practical literature dealing with the management of financial risks reflect the close relationships between insurance and innovations in finance. The book represents an overview of the present state of the art in theoretical research dealing with financial issues of significance for insurance science. It will hopefully provide an impetus to further developments in applied insurance research.

    2016-01-01

    Full Text Available Emergency situations associated with falls are a serious concern for an aging society. Yet following the recent development within ICT, a significant number of solutions have been proposed to track body movement and detect falls using various sensor technologies, thereby facilitating fall detection and in some cases prevention. A number of recent reviews on fall detection methods using ICT technologies have emerged in the literature and an increasingly popular approach considers combining information from several sensor sources to assess falls. The aim of this paper is to review in detail the subfield of fall detection techniques that explicitly considers the use of multisensor fusion based methods to assess and determine falls. The paper highlights key differences between the single sensor-based approach and a multifusion one. The paper also describes and categorizes the various systems used, provides information on the challenges of a multifusion approach, and finally discusses trends for future work.

    2004-05-01

    The past few years have seen a growing interest in quantum mechanical systems with moving boundaries. One of its manifestations was the First International Workshop on Problems with Moving Boundaries organized by Professor J Dittrich in Prague in October 2003. Another event in this series will be the (first) International Workshop on the Dynamical Casimir Effect in Padua in June 2004, organized by Professor G Carugno (see webpage www.pd.infn.it/casimir/ for details). As Guest Editors we invite researchers working in any area related to moving boundaries to contribute to a Topical Issue of Journal of Optics B: Quantum and Semiclassical Optics on the nonstationary Casimir effect and quantum systems with moving boundaries. Our intention is to cover a wide range of topics. In particular, we envisage possible contributions in the following areas: Theoretical and experimental studies on quantum fields in cavities with moving boundaries and time-dependent media. This area includes, in particular, various manifestations of the nonstationary (dynamical) Casimir effect, such as creation of quanta and modifications of Casimir force due to the motion of boundaries. Other relevant subjects are: generation and evolution of nonclassical states of fields and moving mirrors; interaction between quantized fields and atoms in cavities with moving boundaries; decoherence and entanglement due to the motion of boundaries; field quantization in nonideal cavities with moving boundaries taking into account losses and dispersion; nano-devices with moving boundaries. Quantum particles in domains confined with moving boundaries. This area includes: new exact and approximate solutions of the evolution equations (Schrödinger, Klein-Gordon, Dirac, Fokker-Planck, etc); quantum carpets and revivals; escape and tunnelling through moving barriers; evolution of quantum packets in the presence of moving boundaries; ultracold atoms (ions) in traps with moving boundaries. The topical issue is scheduled

    The 12th International Workshop on H-mode Physics and Transport Barriers was held at the Princeton Plasma Physics Laboratory, Princeton, New Jersey, USA between September 30 and October 2, 2009. This meeting was the continuation of a series of previous meetings which was initiated in 1987 and has been held bi-annually since then. Following the recent tradition at the last few meetings, the program was sub- divided into six sessions. At each session, an overview talk was presented, followed by two or three shorter oral presentations which supplemented the coverage of important issues. These talks were followed by discussion periods and poster sessions of contributed papers. The sessions were: Physics of Transition to/from Enhanced Confinement Regimes, Pedestal and Edge Localized Mode Dynamics, Plasma Rotation and Momentum Transport, Role of 3D Physics in Transport Barriers, Transport Barriers: Theory and Simulations and High Priority ITER Issues on Transport Barriers. The diversity of the 90 registered participants was remarkable, with 22 different nationalities. US participants were in the majority (36), followed by Japan (14), South Korea (7), and China (6). This special issue of Nuclear Fusion consists of a cluster of 18 accepted papers from submitted manuscripts based on overview talks and poster presentations. The paper selection procedure followed the guidelines of Nuclear Fusion which are essentially the same as for regular articles with an additional requirement on timeliness of submission, review and revision. One overview paper and five contributed papers report on the H-mode pedestal related results which reflect the importance of this issue concerning the successful operation of ITER. Four papers address the rotation and momentum transport which play a crucial role in transport barrier physics. The transport barrier transition condition is the main focus of other four papers. Finally, four additional papers are devoted to the behaviour and control of

    In the years 2010 to 2013, the share of electricity produced from renewable energy of approximately 17 rose to 24%. For this share compared to conventional production results significantly increased electricity costs, which are allocated on the EEG surcharge to the final consumer. In public discussion of these costs, however, often is ignored that the rapid rise of the share of renewable energy lead to an oversupply of power and therefore decreasing electricity costs in total resulted. By the oversupply the trend of a strong increase in the 2000 to 2008 of Electricity prices on the European electricity markets was broken. The aim of this discussion paper is to reconstruct based on historical price data on the spot market of the Leipzig electricity exchange which prices would be set on the electricity market in the years 2011 to 2013 without the power supply from wind and photovoltaic. The analysis shows that electricity prices have increased without wind and sun, for example, for 2013, due to the significantly lower power supply by an average of 5.29 ct / kWh in the ''day-ahead'' trade on the spot market. The cost of the EEG surcharge of approximately EUR 20.4 billion are thus in 2013 savings of conventional electricity of approximately 31.6 billion euros. This saved a total of approximately 11.2 billion euros in 2013 for the German final consumers. About 269 hours of the year, the demand could not be satisfied with the offered maximal power of 2013. This does not automatically mean that in these situations, major faults (''blackouts'') would have been incurred because the consideration Reserve power plants for system services (''control reserve'') are not taken into account and possible additional import electricity. A stable network operation was reliably ensured only by the supply of renewable energy in these situations, however. Due to the massive development of renewable energy is therefore reduced to

    Public understanding of science (PUS) is a central concept among science communicators. Public understanding of renewable energy (PURE) is proposed as an important sub-concept of PUS. The aim of this paper is to interest and invite renewable energy scientists to join a PURE research project. Four separate important questions for a PURE research project can be identified: (A) Is PURE important? (B) Which issues of PURE are the most important ones, according to renewable energy scientists? (C) What understanding of renewable energy has the general public today, worldwide? (D) How to achieve PURE?.

    Energy Technology Data Exchange (ETDEWEB)

    1982-02-19

    The report is the first to study and discuss the effect of water supply problems of geothermal development. Geothermal energy resources have the potential of making a significant contribution to the U.S. energy supply situation, especially at the regional and local levels where the resources are located. A significant issue of concern is the availability and cost of water for use in a geothermal power operation primarily because geothermal power plants require large quantities of water for cooling, sludge handling and the operation of environmental control systems. On a per unit basis, geothermal power plants, because of their inherent high heat rejection rates, have cooling requirements several times greater than the conventional fossil fuel plants and therefore the supply of water is a critical factor in the planning, designing, and siting of geothermal power plants. However, no studies have been specifically performed to identify the water requirements of geothermal power plants, the underlying causes of water availability problems, and available techniques to alleviate some of these problems. There is no cost data included in the report. The report includes some descriptions of known geothermal areas. [DJE-2005

    Islet transplantation is a very promising therapy for select patients with type 1 diabetes. Continued clinical investigation is required to define the long-term safety and efficacy outcomes before the procedure will be accepted as a standard of care even for those with the most severe manifestations of diabetes. Threatening successful accomplishment of these and other innovative studies designed to advance the field are the complex financial cost accounting issues that pose undue burden on organ procurement organizations and transplant centers trying to manage the costs of the pancreata from deceased donors needed to isolate islets. Compounding the problem is the recent ruling by CMS regarding 'intent to transplant' (CMS-1543-R Dec. 21, 2006: Allocation of Donor Acquisition Costs Incurred by Organ Procurement Organizations) that does not account for the clinical need to complete the manufacturing process for islets before suitability and transplant intent of the pancreata involved can be determined. We provide a consensus document supported by a diverse group of stakeholders in islet transplantation to suggest actions to address this problem.

  4. An issue paper on the use of hydrogen getters in transportation packaging

    Energy Technology Data Exchange (ETDEWEB)

    NIGREY,PAUL J.

    2000-02-01

    The accumulation of hydrogen is usually an undesirable occurrence because buildup in sealed systems pose explosion hazards under certain conditions. Hydrogen scavengers, or getters, can avert these problems by removing hydrogen from such environments. This paper provides a review of a number of reversible and irreversible getters that potentially could be used to reduce the buildup of hydrogen gas in containers for the transport of radioactive materials. In addition to describing getters that have already been used for such purposes, novel getters that might find application in future transport packages are also discussed. This paper also discusses getter material poisoning, the use of getters in packaging, the effects of radiation on getters, the compatibility of getters with packaging, design considerations, regulatory precedents, and makes general recommendations for the materials that have the greatest applicability in transport packaging. At this time, the Pacific Northwest National Laboratory composite getter, DEB [1,4-(phenylethylene)benzene] or similar polymer-based getters, and a manganese dioxide-based getter appear to be attractive candidates that should be further evaluated. These getters potentially can help prevent pressurization from radiolytic reactions in transportation packaging.

    This paper presents a hierarchic framework for environmentally conscious design. The framework integrates both product designers and stakeholders to evaluate not only the product features but also its environmental burden. In evaluating the product's burden, a life cycle assessment of the product is conducted through input-output analysis so that a comprehensive inventory of the product's actions and reactions to the environment could be documented. The analytic hierarchy procedure (AHP) is used to develop priority indices for customer requirements to highlight key features that must be present in the product. Subsequently, the quality function deployment is used to match design requirements to customer requirements. A cost-effective design plan is then finally developed. This framework adopts a systemic approach and ensures that environmentally conscious products are designed and manufactured.

    The 2015 9th Workshop on Recent Issues in Bioanalysis (9th WRIB) took place in Miami, Florida with participation of 600 professionals from pharmaceutical and biopharmaceutical companies, biotechnology companies, contract research organizations and regulatory agencies worldwide. WRIB was once again a 5 day, week-long event - A Full Immersion Bioanalytical Week - specifically designed to facilitate sharing, reviewing, discussing and agreeing on approaches to address the most current issues of interest in bioanalysis. The topics covered included both small and large molecules, and involved LCMS, hybrid LBA/LCMS and LBA approaches, including the focus on biomarkers and immunogenicity. This 2015 White Paper encompasses recommendations emerging from the extensive discussions held during the workshop, and is aimed to provide the bioanalytical community with key information and practical solutions on topics and issues addressed, in an effort to enable advances in scientific excellence, improved quality and better regulatory compliance. Due to its length, the 2015 edition of this comprehensive White Paper has been divided into three parts. Part 3 discusses the recommendations for large molecule bioanalysis using LBA, biomarkers and immunogenicity. Part 1 (small molecule bioanalysis using LCMS) and Part 2 (hybrid LBA/LCMS and regulatory inputs from major global health authorities) have been published in volume 7, issues 22 and 23 of Bioanalysis, respectively.

    This issue of Continuum Magazine covers the depth and breadth of NREL's ever-expanding analytical capabilities. For example, in one project we are leading national efforts to create a computer model of one of the most complex systems ever built. This system, the eastern part of the North American power grid, will likely host an increasing percentage of renewable energy in years to come. Understanding how this system will work is important to its success - and NREL analysis is playing a major role. We are also identifying the connections among energy, the environment and the economy through analysis that will point us toward a 'water smart' future.

    In the last few years, the conditions for extending environmental policy in general and policy dealing with the prevention of water pollution in particular have undergone extensive changes. On the one hand, there has been indisputable considerable success in preventing water pollution which has led to less direct pressure for policy action. On the other hand, the rising sewage levies and the lower political priority assigned in general to environmental policy documented in, e. g. public opinion surveys, has led to water pollution control policy facing very different pressures of justification: more efficient use of funds, improved planning processes, proof of the achievable benefit, but also stopping the increase in levies or not hindering economic development, these or similar slogans are the objections brought against water pollution control. Regardless of how unambiguous these terms appear when used as slogans in this way, they become diffuse and unclear if regarded more closely. This paper therefore attempts to reveal the reasons for possible misunderstandings and misinterpretations on the one hand and, on the other, to reveal the basic problems and uncertainties which are necessarily linked with an assessment of costs and benefits. In order to do this, three areas are examined: level of actors and analysis, evaluation methods and assessment of costs and benefits. (orig.)

    1996-06-27

    The various issues concerning the proposed concept of Canadian Renewable and Conservation Expense as a means to promoting sustainable development were outlined in a working paper by officials of Finance Canada and Natural Resources Canada. Briefly, to promote sustainable development, the 1996 Canadian budget proposed to modify income tax arrangements to introduce a category of Canadian Renewable and Conservation Expense (CRCE), dealing with exploration expenses which would be fully tax deductible. The changes were introduced in recognition of the fact that the renewable energy sector would need assistance in financing costs such as feasibility studies. A framework to define other eligible expenses for the new CRCE category was also provided. This framework was developed by focusing on the typical costs relating to renewable energy projects. The objective of the CRCE was to ensure that costs in the renewable energy and energy conservation sector receive tax treatment similar to those in the non-renewable energy sector. 15 refs., 1 tab.

    This paper builds on IEA publications, Deploying Renewables, Principles for Effective Policies and Deploying Renewables, Best and Future Policy Practice, that discuss the 'integrated policy approach,' whereby renewable energy technologies require different support policies at different stages of their maturity pathways. The paper discusses how the integrated policy approach applies to renewable heat. It attempts to provide guidance for policy-makers on renewable heat throughout the different phases of the policy lifecycle, allowing for the specific challenges of renewable heat and needs of the many stakeholders involved. Stimulating a market for heat involves challenges that are different and, often, more difficult to overcome than in the electricity and transport sectors.

    On June 27 and 28, 1989, the US Department of Energy (DOE) national laboratories were convened to discuss plans for the development of a National Energy Strategy (NES) and, in particular, the analytic needs in support of NES that could be addressed by the laboratories. As a result of that meeting, interlaboratory teams were formed to produce analytic white papers on key topics, and a lead laboratory was designated for each core laboratory team. The broad-ranging renewables assignment is summarized by the following issue statement from the Office of Policy, Planning and Analysis: to what extent can renewable energy technologies contribute to diversifying sources of energy supply What are the major barriers to greater renewable energy use and what is the potential timing of widespread commercialization for various categories of applications This report presents the results of the intensive activity initiated by the June 1989 meeting to produce a white paper on renewable energy. Scores of scientists, analysts, and engineers in the five core laboratories gave generously of their time over the past eight months to produce this document. Their generous, constructive efforts are hereby gratefully acknowledged. 126 refs., 44 figs., 32 tabs.

    2013-07-01

    It is the position of the Academy of Nutrition and Dietetics that individuals have the right to request or refuse nutrition and hydration as medical treatment. Registered dietitians should work collaboratively as part of an interprofessional team to make recommendations on providing, withdrawing, or withholding nutrition and hydration in individual cases and serve as active members of institutional ethics committees. This practice paper provides a proactive, integrated, systematic process to implement the Academy's position. The position and practice papers should be used together to address the history and supporting information of ethical and legal issues of feeding and hydration identified by the Academy. Elements of collaborative ethical deliberation are provided for pediatrics and adults and in different conditions. The process of ethical deliberation is presented with the roles and responsibilities of the registered dietitian and the dietetic technician, registered. Understanding the importance and applying concepts dealing with cultural values and religious diversity is necessary to integrate clinical ethics into nutrition care. Incorporating screening for quality-of-life goals is essential before implementing the Nutrition Care Process and improving health literacy with individual interactions. Developing institution-specific policies and procedures is necessary to accelerate the practice change with artificial nutrition, clinical ethics, and quality improvement projects to determine best practice. This paper supports the "Position of the Academy of Nutrition and Dietetics: Ethical and Legal Issues of Feeding and Hydration" published in the June 2013 issue of the Journal of the Academy of Nutrition and Dietetics.

    together scientists and practitioners who conduct research on privacy and security issues in data mining and machine learning to discuss the most recent advances in these research areas, identify open problem domains and propose possible solutions. The workshop was organized along four core subjects: (a data privacy and security issues, (b theoretical aspects of machine learning for security applications, (c privacy-preserving data mining, machine learning and applications, and (d security applications of machine learning. The present special issue contains three extended papers that have been selected among the papers presented at PSDML 2010 focusing mainly on the privacy aspects of data mining and machine learning. The first paper by Manas A. Pathak and Bhiksha Raj is titled 'Efficient Protocols for Principal Eigenvector Computation over Private Data'. It presents an efficient secure multiparty computation protocol for computing the principal eigenvector of a collection of data matrices that belong to semi-honest parties, coordinated by a semi-honest arbitrator. The protocol is augmented with randomization, data padding and oblivious transfer to conceal the information which the parties can learn from the intermediate results. The authors provide an analysis of correctness, security and efficiency of the protocol together with experimental results from a prototype implementation. The second paper by Henrik Grosskreutz, Benedikt Lemmen and Stefan Ruping is titled 'Secure Distributed Subgroup Discovery in Horizontally Partitioned Data'. The paper studies the problem of subgroup discovery and presents new secure protocols which support distributed subgroup discovery on horizontally partitioned data. The authors analyze the properties of their top-1 subgroup discovery protocol and prove that it leaks only little information, namely the size of the database and the share of positive records. They also report experimental results which demonstrate the feasibility of the

    The use of renewable materials is essential in future technologies to harmonize with our living environment. Renewable materials can maintain our resources from the environment so as to overcome degradation of natural environmental services and diminished productivity. This paper reviews recent advancement of renewable materials for smart material applications, including wood, cellulose, chitin, lignin, and their sensors, actuators and energy storage applications. To further improve functionality of renewable materials, hybrid composites of inorganic functional materials are introduced by incorporating carbon nanotubes, titanium dioxide and tin oxide conducting polymers and ionic liquids. Since renewable materials have many advantages of biocompatible, sustainable, biodegradable, high mechanical strength and versatile modification behaviors, more research efforts need to be focused on the development of renewable smart materials.

It provides more detailed data and analysis on policies for Deploying Renewables, and is intended to complement the main publication. It provides an account of the strategic drivers underpinning renewable energy (RE) technology deployment (energy security, economic development and environment protection) and assesses RE technologies with respect to these drivers, including an estimate of GHG emissions reductions due to RE technologies. The paper also explores the different barriers to deploying renewables at a given stage of market maturity and discusses what tools policy makers can avail of to succeed in removing deployment barriers. An additional topical highlight explores the challenges associated with accelerating the diffusion of RE technologies in developing countries.

  18. Essays in renewable energy and emissions trading

    Science.gov (United States)

    Kneifel, Joshua D.

    Environmental issues have become a key political issue over the past forty years and has resulted in the enactment of many different environmental policies. The three essays in this dissertation add to the literature of renewable energy policies and sulfur dioxide emissions trading. The first essay ascertains which state policies are accelerating deployment of non-hydropower renewable electricity generation capacity into a states electric power industry. As would be expected, policies that lead to significant increases in actual renewable capacity in that state either set a Renewables Portfolio Standard with a certain level of required renewable capacity or use Clean Energy Funds to directly fund utility-scale renewable capacity construction. A surprising result is that Required Green Power Options, a policy that merely requires all utilities in a state to offer the option for consumers to purchase renewable energy at a premium rate, has a sizable impact on non-hydro renewable capacity in that state. The second essay studies the theoretical impacts fuel contract constraints have on an electricity generating unit's compliance costs of meeting the emissions compliance restrictions set by Phase I of the Title IV SO2 Emissions Trading Program. Fuel contract constraints restrict a utility's degrees of freedom in coal purchasing options, which can lead to the use of a more expensive compliance option and higher compliance costs. The third essay analytically and empirically shows how fuel contract constraints impact the emissions allowance market and total electric power industry compliance costs. This paper uses generating unit-level simulations to replicate results from previous studies and show that fuel contracts appear to explain a large portion (65%) of the previously unexplained compliance cost simulations. Also, my study considers a more appropriate plant-level decisions for compliance choices by analytically analyzing the plant level decision-making process to

  11. An Evaluation of Urban Renewal Policies of Shenzhen, China

    Guiwen Liu

    2017-06-01

    Full Text Available Urban renewal is a pragmatic approach in the sustainable urban development of urban areas, and has now become an essential strategy for most metropolises in China. The question of how urban renewal can best be realized has gained the attention of urban planning researchers looking to formulate practical evidence-based urban renewal policies through policy instruments. This paper analyzes the urban renewal policies of Shenzhen, a pioneer city in China in the promulgation of urban renewal legislation. In doing so, an analytical framework is established by focusing on three main policy instruments, along with several sub-instruments within them. Shenzhen’s five main urban renewal policies, issued between 2009 and 2016, are analyzed through this framework. Content analysis and pattern-matching is used in the review and analysis of the data. The results show that “Environment” side policies tend to be the most widely applied by the Shenzhen municipal government. Additionally, “Regulation Control” and “Goal-planning” policies are the two instruments most frequently adopted as sub-instruments. Moreover, it is found that the application of “Supply” side polices and “Demand” side polices needs be strengthened. These findings identify the types of urban renewal policies currently employed in China and provide a clear understanding of the current policy priorities, with suggestions and insight into further urban renewal policy initiatives for Shenzhen and beyond.

  12. Renewable Substitutability Index: Maximizing Renewable Resource Use in Buildings

    Directory of Open Access Journals (Sweden)

    Ravi S. Srinivasan

    2015-05-01

    Full Text Available In order to achieve a material and energy balance in buildings that is sustainable in the long run, there is an urgent need to assess the renewable and non-renewable resources used in the manufacturing process and to progressively replace non-renewable resources with renewables. Such progressive disinvestment in the non-renewable resources that may be substituted with renewable resources is referred to as “Renewable Substitutability” and if implemented, this process will lead to a paradigm shift in the way building materials are manufactured. This paper discusses the development of a Renewable Substitutability Index (RSI that is designed to maximize the use of renewable resources in a building and quantifies the substitution process using solar emergy (i.e., the solar equivalent joules required for any item. The RSI of a building or a building component, i.e., floor or wall systems, etc., is the ratio of the renewable resources used during construction, including replacement and maintenance, to the building’s maximum renewable emergy potential. RSI values range between 0 and 1.0. A higher RSI achieves a low-energy building strategy promoting a higher order of sustainability by optimizing the use of renewables over a building’s lifetime from formation-extraction-manufacturing to maintenance, operation, demolition, and recycle.

  1. COMPLETE CHARACTERIZATION OF WHEAT STRAW (TRITICUM AESTIVUM PBW-343 L. EMEND. FIORI & PAOL. – A RENEWABLE SOURCE OF FIBRES FOR PULP AND PAPER MAKING

    Directory of Open Access Journals (Sweden)

    Shalini Singh

    2011-02-01

    Full Text Available Triticum aestivum PBW-343 is grown in most of the regions of India, and it is one of the renewable sources most suitable for papermaking. Anatomical studies illustrate that vascular bundles near the periphery contain a strong sheath of sclerenchyma cells, which constitutes about 80% of the fibers. The total fibers in wheat straw are about 39.20%, and parenchyma and epidermal cells account for 32.10, and 23.56%, respectively, of the total cells. The dimensions of wheat straw fibers are: average fiber length 1.18 mm, fiber width 13.60 µm, lumen diameter 5.68 µm, and cell wall thickness 3.96 µm. The dimensions of non-fibrous cells are: parenchyma 445x124 µm, vessels 96x57 µm, and epidermal cells 390x38 µm, which lie between the corresponding values for rice straw, and bagasse. Flexibility coefficients and Runkel ratio of wheat straw fires are quite comparable to bamboo. The low lignin contents of wheat straw reflect that it requires mild cooking conditions; however, hemicelluloses are on higher side. Addition of AQ under optimum soda cooking conditions improves pulp yield by 0.75%, and lowers kappa number by 26.1%. Optimum strength properties are obtained at 45±1 oSR except tear index, which declines with increased refining. The fine contents are much higher, and relatively comparable to Eucalyptus tereticornis in terms of curl index and kinks per mm.

    Renewable energy has developed spectacularly in Spain since the European Union started a process of energy policy reform. A review of Spanish State legislation on renewable energies confirms that the success in installing renewable energy is attributable to public aid. Andalusia is one of the autonomous communities, which has simultaneously developed the legal framework and very successfully implemented the introduction of renewable power. When implementing the central government's policy, the Andalusian regional government prioritised increases in both surface cover by wind and solar plants (thermal and photovoltaic energy) and in the number of companies involved. However, this development of renewable energies took place without any proper integration into regional spatial and landscape planning. This paper explores renewable power implementation in Andalusia through regulatory measures put in place over the last decade to develop renewable energy systems and the way they can be managed alongside planning issues. The location of large-scale renewable plants has had consequences for territory in the socio-political context of renewable energy promotion. The main findings focus on renewable energy plant sprawl throughout rural areas in Andalusia with no clear effect on landscape management and no firm backing from the local population.

    2017-08-01

    Full Text Available This paper analyses the impact on renewable energy sources integrated into the Romanian power system on the electrical network operation considering the reduction of electricity consumption with respect to the 1990s. This decrease has led to increased difficulties in integrating the renewable energy sources into the power system (network reinforcements, as well as issues concerning the balance of production/consumption. Following the excess of certain proportions of the energy mix, intermittent renewable energy sources require the expansion of networks, storage, back-up capacities and efforts for a flexible consumption, in the absence of which renewable energy sources cannot be used or the grid can be overloaded. To highlight the difficulty of connecting some significant capacities installed in wind power plants and photovoltaic installation, the paper presents a case study for Dobrogea area that has the most installed capacity from renewable energy sources in operation.

    Innovation is the commercial exploitation of an invention requiring marketing, management, financial and legal skills. Renewable energy is a high technology, knowledge-based business with a global market and, being decentralised, is suited to all regions of the world. Key issues for an innovation strategy for renewable energy are identified. They include: accessing the available finance for innovation; developing local expertise; networking with renewable energy experts; identifying the best available technology, expertise and technology transfer arrangements and adapting these to the region and enterprise. The ultimate success of the strategy will be judged by the new level of economic activity in the enterprise. (UK)

    Full Text Available Construction equipment planning and selection plays crucial role for the success of construction firms.Inadequate manual processes of equipmentplanning and selection and the subjective decisions of equipment managers usually result in major losses in construction firms. An indispensable item of resources, it produces output at accelerated speed, enables completion of task in limited time. Equipment saves manpower, which is becoming costly and more demanding day by day. Equipment improves quality, productivity and safety. Construction equipment planning aims at identifying construction equipment for executing project tasks, assessing equipment performance capability, forecasting date wise requirement of number and type of equipment and finally participating in the selection of equipment to be acquired. To derive full benefits from the equipment, there should be proper selection and good planning of its operations. This paper deals with the planning and selection procedure for equipment adopted by a company to achieve its objective of timely project completion.

  13. Will Renewable Energy Save Our Planet?

    2010-06-01

    This paper discusses some important fundamental issues behind application of renewable energy (RE) to evaluate its impact as a climate change mitigation technology. The discussed issues are the following: definition of renewable energy, concentration of RE by weight and volume, generation of electrical energy and its power at unit area, electrical energy demand per unit area, life time approach vs. layman approach, energy return time, energy return ratio, CO2 return time, energy mix for RES production and use, geographical distribution of RES use, huge scale of energy shift from RES to non-RES, increase in energy consumption, Thermodynamic equilibrium of earth, and probable solutions for energy future of our energy and environmental crisis of today. The future solution (that would enable to human civilization further welfare, and good living, but with lower release of CO2 in atmosphere) may not be only RES. This will rather be an energy mix that may contain nuclear energy, non-nuclear renewable energy, or fossil energy with CO2 sequestration, efficient energy technologies, energy saving, and energy consumption decrease.

    Renewable energy remains a contested topic in South Africa. This paper argues that South Africa can build on the momentum surrounding its introduction of a feed-in tariff by enacting policies that may, if given adequate funding and political effort, allow the country to be a world leader in renewable energy. Given a variety of renewable energy policy options for moving forward, a majority of stakeholders consulted in this study strongly prefer the development of a renewable energy manufacturing cluster, in which government develops coordinated policy mechanisms that attract renewable energy manufacturers, over three other policies suggested by the authors. Interviews with key informants that play critical roles in this decision-making process suggest that there are reasons to remain cautiously optimistic about the country's renewable energy future while cognizant of the challenges that must still be overcome. Opportunities for a low carbon renewable energy transition in South Africa include the prevalence of broad stakeholder consultation, facilitated by civil society, and an innovative policy development context. Significant impediments also exist, however, and include pervasive social issues such as poverty and political inertia, along with the ongoing difficulties facing renewable energy technologies in reaching grid parity with inexpensive and abundant South African coal. - Highlights: > Numerous opportunities exist for a low carbon energy transition in South Africa. > Stakeholders in study prefer development of a renewable energy manufacturing cluster. > Significant impediments still exist, including grid parity, poverty, and inequality.

    With organizations and individuals increasingly interested in accounting for their carbon emissions, greater attention is being placed on how to account for the benefits of various carbon mitigation actions available to consumers and businesses. Generally, organizations can address their own carbon emissions through energy efficiency, fuel switching, on-site renewable energy systems, renewable energy purchased from utilities or in the form of renewable energy certificates (RECs), and carbon offsets. This paper explores the role of green power and carbon offsets in carbon footprinting and the distinctions between the two products. It reviews how leading greenhouse gas (GHG) reporting programs treat green power purchases and discusses key issues regarding how to account for the carbon benefits of renewable energy. It also discusses potential double counting if renewable energy generation is used in multiple markets.

  2. Renewable Energy Technology—Is It a Manufactured Technology or an Information Technology?

    Directory of Open Access Journals (Sweden)

    Kwok L. Shum

    2010-07-01

    Full Text Available Socio-technical or strategic approach to renewable energy deployment all suggests that the uptake of renewable energy technology such as solar photovoltaic is as much a social issue as a technical issue. Among social issues, one most direct and immediate component is the cost of the renewable energy technology. Because renewable electricity provides no new functionality—a clean electron does the same work as a dirty electron does—but is relatively expensive compared with fossil fuel based electricity, there is currently an under-supply of renewable electricity. Policy instruments based on economics approaches are therefore developed to encourage the production and consumption of renewable electricity, aiming to remediate the market inefficiencies that stem from the failure in internalizing the environmental or social costs of fossil fuels. In this vein, the most discussed instruments are renewable portfolio standard or quota based system and the general category of feed-in tariff. Feed-in tariff is to support output or generation of the renewable electricity by subsidizing revenues. The existing discussions have all concerned about the relative effectiveness of these two instruments in terms of cost, prices and implementation efficiency. This paper attempts a different basis of evaluation of these two instruments in terms of cost and (network externality effects. The cost effect is driven by deploying the renewable as a manufactured technology, and the network externality effect is driven by deploying the renewable as an information technology. The deployment instruments are studied in terms of how these two effects are leveraged in the deployment process. Our formulation lends itself to evolutionary policy interpretation. Future research directions associated with this new energy policy framework is then suggested.

  4. Water-the Nation's Fundamental Climate Issue A White Paper on the U.S. Geological Survey Role and Capabilities

    Lins, Harry F.; Hirsch, Robert M.; Kiang, Julie

    2010-01-01

    Of all the potential threats posed by climatic variability and change, those associated with water resources are arguably the most consequential for both society and the environment (Waggoner, 1990). Climatic effects on agriculture, aquatic ecosystems, energy, and industry are strongly influenced by climatic effects on water. Thus, understanding changes in the distribution, quantity and quality of, and demand for water in response to climate variability and change is essential to planning for and adapting to future climatic conditions. A central role of the U.S. Geological Survey (USGS) with respect to climate is to document environmental changes currently underway and to develop improved capabilities to predict future changes. Indeed, a centerpiece of the USGS role is a new Climate Effects Network of monitoring sites. Measuring the climatic effects on water is an essential component of such a network (along with corresponding effects on terrestrial ecosystems). The USGS needs to be unambiguous in communicating with its customers and stakeholders, and with officials at the Department of the Interior, that although modeling future impacts of climate change is important, there is no more critical role for the USGS in climate change science than that of measuring and describing the changes that are currently underway. One of the best statements of that mission comes from a short paper by Ralph Keeling (2008) that describes the inspiration and the challenges faced by David Keeling in operating the all-important Mauna Loa Observatory over a period of more than four decades. Ralph Keeling stated: 'The only way to figure out what is happening to our planet is to measure it, and this means tracking changes decade after decade and poring over the records.' There are three key ideas that are important to the USGS in the above-mentioned sentence. First, to understand what is happening requires measurement. While models are a tool for learning and testing our understanding

    This paper presents the learning of a series of studies that analyse the problems and perspectives of converting the present energy system into a 100 % renewable energy system using a smart energy systems approach. As opposed to, for instance, the smart grid concept, which takes a sole focus...... on the electricity sector, smart energy systems include the entire energy system in its approach to identifying suitable energy infrastructure designs and operation strategies. The typical smart grid sole focus on the electricity sector often leads to the conclusion that transmission lines, flexible electricity...... are to be found when the electricity sector is combined with the heating and cooling sectors and/or the transportation sector. Moreover, the combination of electricity and gas infrastructures may play an important role in the design of future renewable energy systems. The paper illustrates why electricity smart...

    Job generation has been a part of the national dialogue surrounding energy policy and renewable energy (RE) for many years. RE advocates tout the ability of renewable energy to support new job opportunities in rural America and the manufacturing sector. Others argue that spending on renewable energy is an inefficient allocation of resources and can result in job losses in the broader economy. The report, Study of the Effects on Employment of Public Aid to Renewable Energy Sources, from King Juan Carlos University in Spain, is one recent addition to this debate. This report asserts that, on average, every renewable energy job in Spain 'destroyed' 2.2 jobs in the broader Spanish economy. The authors also apply this ratio to the U.S. context to estimate expected job loss from renewable energy development and policy in the United States. This memo discusses fundamental and technical limitations of the analysis by King Juan Carlos University and notes critical assumptions implicit in the ultimate conclusions of their work. The memo also includes a review of traditional employment impact analyses that rely on accepted, peer-reviewed methodologies, and it highlights specific variables that can significantly influence the results of traditional employment impact analysis.

    Against the backdrop of increasing energy demands, the threat of climate change and dwindling fuel reserves, finding reliable, diverse, sustainable/renewable, affordable energy resources has become a priority for many countries. Marine energy conversion systems are at the forefront of providing such a resource. Most marine renewable energy conversion systems require tribological components to convert wind or tidal streams to rotational motion for generating electricity while wave machines typically use oscillating hinge or piston within cylinder geometries to promote reciprocating linear motion. This paper looks at the tribology of three green marine energy systems, offshore wind, tidal and wave machines. Areas covered include lubrication and contamination, bearing and gearbox issues, biofouling, cavitation erosion, tribocorrosion, condition monitoring as well as design trends and loading conditions associated with tribological components. Current research thrusts are highlighted along with areas needing research as well as addressing present-day issues related to the tribology of offshore energy conversion technologies.

  14. The impacts of non-renewable and renewable energy on CO2 emissions in Turkey.

    2017-06-01

    As a result of great increases in CO2 emissions in the last few decades, many papers have examined the relationship between renewable energy and CO2 emissions in the energy economics literature, because as a clean energy source, renewable energy can reduce CO2 emissions and solve environmental problems stemming from increases in CO2 emissions. When one analyses these papers, he/she will observe that they employ fixed parameter estimation methods, and time-varying effects of non-renewable and renewable energy consumption/production on greenhouse gas emissions are ignored. In order to fulfil this gap in the literature, this paper examines the effects of non-renewable and renewable energy on CO2 emissions in Turkey over the period 1970-2013 by employing fixed parameter and time-varying parameter estimation methods. Estimation methods reveal that CO2 emissions are positively related to non-renewable energy and renewable energy in Turkey. Since policy makers expect renewable energy to decrease CO2 emissions, this paper argues that renewable energy is not able to satisfy the expectations of policy makers though fewer CO2 emissions arise through production of electricity using renewable sources. In conclusion, the paper argues that policy makers should implement long-term energy policies in Turkey.

    Full Text Available The concern of this paper is urban renewal projects; it investigates how such projects get off the ground. A variety of bodies have examined and devised instruments to tackle the inherent difficulties. “How can cities overcome critical factors in the successful start of urban renewal projects” is the main research question, explored using three supportive questions. An embedded case has been selected to illustrate a successful urban renewal project. Kingdon’s opportunity windows framework provides the theoretical background. The concepts provided in the theory were discussed and operationalized. The core issue is opportunity windows. We explored the occurrence of these concepts and processes in the Hart van Zuid case. We argued that successful projects are an illustration of policy windows of opportunity. Becoming successful in renewal projects entails opening and taking advantage of windows of opportunity. We have pointed out factors that influence the occurrence of opportunity windows in the studied case.

The goal of the SPRINGL workshop series is to provide a forum for researchers working in the area of geospatial data security and privacy. Both security and privacy are critical for geospatial applications because of the dramatic increase and dissemination of geospatial data in several application contexts including homeland security, environmental crises, and natural and industrial disasters. Furthermore, geospatial infrastructures are being leveraged by companies to provide a large variety of location-based services (LBS able to tailor services to users. However, despite the increase of publicly accessible geospatial information only little attention is being paid to how to secure geospatial information systems (GIS and LBS. Privacy is also of increasing concern given the sensitivity of personally-identifiable location information. This is despite major advancements that have been made in secure computing infrastructures and the secure and privacy-preserving management of traditional (relational data in particular. The discussion at the workshop spanned across security and privacy aspects, as they relate to the management of geospatial data and to the development of emerging LBS. The present special issue of Transactions on Data Privacy contains four extended papers, focusing on privacy, that have been selected from the papers presented at SPRINGL 2008.

    Many consumers today are purchasing renewable energy in large part for the greenhouse gas (GHG) emissions benefits that they provide. Emerging carbon regulation in the US has the potential to affect existing markets for renewable energy. Carbon cap-and-trade programs are now under development in the Northeast under the Regional Greenhouse Gas Initiative (RGGI) and in early stages of development in the West and Midwest. There is increasing discussion about carbon regulation at the national level as well. While renewable energy will likely benefit from carbon cap-and-trade programs because compliance with the cap will increase the costs of fossil fuel generation, cap-and-trade programs can also impact the ability of renewable energy generation to affect overall CO{sub 2} emissions levels and obtain value for those emissions benefits. This paper summarizes key issues for renewable energy markets that are emerging with carbon regulation, such as the implications for emissions benefits claims and voluntary market demand and the use of renewable energy certificates (RECs) in multiple markets. It also explores policy options under consideration for designing carbon policies to enable carbon markets and renewable energy markets to work together. (author)

    Dana L. Kelly; Andrei Rodionov; Jens Uwe-Klugel

    2008-09-01

    This paper examines practical issues in the statistical analysis of component aging data. These issues center on the stochastic process chosen to model component failures. The two stochastic processes examined are repair same as new, leading to a renewal process, and repair same as old, leading to a nonhomogeneous Poisson process. Under the first assumption, times between failures can treated as statistically independent observations from a stationary process. The common distribution of the times between failures is called the renewal distribution. Under the second process, the times between failures will not be independently and identically distributed, and one cannot simply fit a renewal distribution to the cumulative failure times or the times between failures. The paper illustrates how the assumption made regarding the repair process is crucial to the analysis. Besides the choice of stochastic process, other issues that are discussed include qualitative graphical analysis and simple nonparametric hypothesis tests to help judge which process appears more appropriate. Numerical examples are presented to illustrate the issues discussed in the paper.

    Renewable cooling technologies do not play a major role in the climate protection discussion in the European Union today. At the same time the cooling demand is expected to increase significantly in the coming decades. Renewable cooling technologies could contribute to the EU renewable energy target if an appropriate political framework for a further spread of the technologies is created. This renewable cooling policy report intends to support the dissemination of renewable cooling technologies. It provides an overview of the situation, technologies and potential for cool-ing from renewable sources and identifies key areas in which further investigation is required. The report shows that there is a great need for the creation of a political framework supporting the market diffusion of renewable cooling technologies. Firstly the question of a commonly accepted definition on renewable cooling is being addressed. Secondly renewable cooling technologies are described and the today's role of cooling in European statistics and policies is analysed. In the next step existing studies are evaluated to compare the expected development of the cooling demand in Europe to the market potential of renewable cooling. At the end of the paper a long-term vision for renewable cooling is described and first steps towards a European roadmap for renewable cooling are given.

    Full Text Available The article consists of two parts. The first deals with the theoretical framework of urban rehabilitation. Literature provides the basis for a conclusion, which is that the key issue in rehabilitation projects is legitimate negotiation of various interests between participating individuals and institutions. In the second part this presentation and analyses of events that took place at the urban design workshop organised within the framework of the research project Renewal of housing estates in Ljubljana, provide experiential confirmation of the starting thesis. We established that the directly involved residents were willing to actively participate in rehabilitation procedures, however the process is never triggered, because of insufficient capacities in institutional frameworks. In conclusion several real proposals are shown, namely, how to surmount obstacles in urban rehabilitation and especially in larger housing estates built after World War 2.

  11. Who Owns Renewable Energy Certificates?

    Energy Technology Data Exchange (ETDEWEB)

    Holt, Edward; Wiser, Ryan; Bolinger, Mark

    2006-06-01

    Renewable energy certificates (RECs) are tradable instruments that convey the attributes of a renewable energy generator and the right to make certain claims about energy purchases. RECs first appeared in US markets in the late 1990s and are particularly important in states that accept or require them as evidence of compliance with renewables portfolio standards (RPS). The emergence of RECs as a tradable commodity has made utilities, generators, and regulators increasingly aware of the need to specify who owns the RECs in energy transactions. In voluntary transactions, most agree that the question of REC ownership can and should be negotiated privately between the buyer and the seller, and should be clearly established by contract. Claims about purchasing or using renewable energy should only be made if REC ownership can be documented. In many other cases, however, renewable energy transactions are either mandated or encouraged through state or federal policy. Because of the recent appearance of RECs, legislation and regulation mandating the purchase of renewable energy has sometimes been silent on the disposition of the RECs associated with that generation. Furthermore, some renewable energy contracts pre-date the existence of RECs, and therefore do not address REC ownership. In both of these instances, the issue of REC ownership must often be answered by legislative or regulatory authorities. The resulting uncertainty in REC ownership has hindered the development of robust REC markets and has, in some cases, led to contention between buyers and sellers of renewable generation. This article, which is based on a longer Berkeley Lab report, reviews federal and state efforts to clarify the ownership of RECs from Qualifying Facilities (QFs) that sell their generation under the Public Utility Regulatory Policies Act (PURPA) of 1978. The full report also addresses state efforts to clarify REC ownership in two other situations, customer-owned generation that benefits

    Full Text Available By 2020, intermittent renewable small scale energy sources (e.g. wind and solar energy are expected to represent about 17% of the EU’s total electricity consumption. All national overriding energy policy objectives are to ensure competitive, secure and sustainable energy for the economy and for society. Renewable energy, allied with energy efficiency, is often found crucial to meet these goals of secure sustainable and competitive energy supplies reducing dependency on expensive fossil imports and underpinning the move towards a low carbon economy while delivering green jobs to the economy. This all contributes to national competitiveness and the jobs and economic growth agenda. However, a straight forward implementation of renewable energy options is not easy, due to various barriers and obstacles. For most SMEs, the concept of generating their own renewable energy is still more of academic than genuine interest. In general, several barriers are experienced, such as high capital investments, slow return on investment, and the lack of knowledge of the benefits. There is a need for education on the benefits and drawbacks of sustainable energy, as well as a greater contribution to costs for this to work. In this paper we describe the intermediate outcomes of a European Partnership under the name of GREAT (Growing Renewable Energy Applications and Technologies, funded under the INTERREG IVB NWE Programme. GREAT aims to encourage communities and small to medium size enterprises (SMEs in Ireland, the United Kingdon, Belgium and The Netherlands to develop technological solutions for Smart Grid, Renewable Energy and Distributive Generation; research and develop policy issues for regulatory authorities and provide structured co-operation opportunities between SMEs and research institutes / technology developers. We developed GREAT spreadsheets to facilitate SMEs in each country to calculate the return-on-investment of renewable energy sources, such as

    Full Text Available Energy is crucial to economic progress, but the contemporary worldwide population increase that demands greater energy generated from conventional exhaustible resources, an energy price upsurge, and environmental concerns, imperils sustainable economic growth. Nevertheless, switching to renewable energy produced from naturally replenished resources promotes energy security, likewise addressing issues such as global warming and climate change. This paper aims at exploring the influence and causal relation between renewable energy, both overall and by type, and sustainable economic growth of European Union (EU-28 countries for the period of 2003–2014. We notice that the mean share of renewable energy in the gross final energy consumption is 15%, while the mean share of renewable energy in transport fuel consumption is 3%, which are below the thresholds of 20% and 10%, respectively, as set by the EU Directive 2009/28/EC. By estimating panel data fixed-effects regression models, the results provide support for a positive influence of renewable energy overall, as well as by type, namely biomass, hydropower, geothermal energy, wind power, and solar energy on gross domestic product per capita. However, biomass energy shows the highest influence on economic growth among the rest of renewable energy types. In fact, a 1% increase of the primary production of solid biofuels increases GDP per capita by 0.16%. Besides, cointegrating regressions set on panel fully modified and dynamic ordinary least squares regressions confirm the positive influence related to the primary production of renewable energies on economic growth. A 1% increase in primary production of renewable energies increases GDP per capita by 0.05%–0.06%. However, the results of Granger causality based on panel vector error correction model indicate both in short-run and long-run a unidirectional causal relationship running from sustainable economic growth to the primary production of

    In April 1996, the Federal Regulatory Commission (PERC) approved Orders 888 and 889 and released a draft rule for public comment on capacity reservation tariffs (CRTs). Order No. 888 requires electric utilities to file transmission tariffs that would allow transmission access to third parties who want to conduct wholesale transactions, and Order No. 889 requires transmission-owning utilities to set up open access, same-time information systems (OASIS), using commercial software and Internet protocols. This paper discusses these Orders in detail, as well as some of the issues before FERC with implications for renewables, which include: transmission pricing; transmission terms and conditions; reassignment of transmission capacity; defining state and FERC jurisdiction over transmission and distribution; the pricing of ancillary services; and the adoption and implementation of independent system operators.

    This paper reports on renewable portfolio standards (RPS) and how the RPS rules vary from state to state. This variation presents important challenges to successful implementation. Key issues are discussed in terms of resource availability, solar-specific provisions, and political and regulatory consistency, and their impacts on the ability to finance new renewable energy projects. This report emphasizes the fact that a successful RPS policy must balance a state's goals for fuel diversity, economic development, price effects, and environmental benefits.

    Full Text Available Those familiar with the fifth intergovernmental Penal on Climate Change report presented in late 2013 can no longer seriously doubt that climate change has become a reality. Although the issue has been the subject of several high profile international conferences, little has been achieved so far. Fossil power plants still continue to emit massive amounts of greenhouse gases further accelerating climate change. There is, however, an alternative to our current climate-damaging way of energy production: The complete transition towards 100 percent renewable energies. This paper examines the way in which an industrialized country like Germany can become a 100 percent renewable by 2020.

    The subject of this paper is innovative policies to promote renewable energy. The renewable energy industry has made great progress in the last decade. Prices have dropped four-fold or more, and reliability has increased dramatically. By most measures, then, the renewable energy industry should be poised to become a mainstream success. But upon closer examination, it appears instead that our society may snatch defeat from the jaws of victory. Unless something changes, and soon, we will watch dozens of promising renewable technologies stumble and fail. This paper examines what drives this ironic situation, where on the one hand our renewable energy technologies are more cost-effective than ever, and on the other our society is not yet poised to purchase them in sufficient quantities, and what can be to overcome this dangerous irony. 1 fig.

  10. State Clean Energy Practices: Renewable Portfolio Standards

    Hurlbut, D.

    2008-07-01

    The State Clean Energy Policies Analysis (SCEPA) project is supported by the Weatherization and Intergovernmental Program within the Department of Energy's Office of Energy Efficiency and Renewable Energy. This project seeks to quantify the impacts of existing state policies, and to identify crucial policy attributes and their potential applicability to other states. The goal is to assist states in determining which clean energy policies or policy portfolios will best accomplish their environmental, economic, and security goals. For example, a renewable portfolio standard (RPS) mandates an increase in the use of wind, solar, biomass, and other alternatives to fossil and nuclear electric generation. This paper provides a summary of the policy objectives that commonly drive the establishment of an RPS, the key issues that states have encountered in implementing an RPS, and the strategies that some of the leading states have followed to address implementation challenges. The factors that help an RPS function best generally have been explored in other analyses. This study complements others by comparing empirical outcomes, and identifying the policies that appear to have the greatest impact on results.

  11. Power marketing and renewable energy

    Energy Technology Data Exchange (ETDEWEB)

    Fang, J.M.

    1997-09-01

    Power marketing refers to wholesale and retail transactions of electric power made by companies other than public power entities and the regulated utilities that own the generation and distribution lines. The growth in power marketing has been a major development in the electric power industry during the last few years, and power marketers are expected to realize even more market opportunities as electric industry deregulation proceeds from wholesale competition to retail competition. This Topical Issues Brief examines the nature of the power marketing business and its relationship with renewable power. The information presented is based on interviews conducted with nine power marketing companies, which accounted for almost 54% of total power sales by power marketers in 1995. These interviews provided information on various viewpoints of power marketers, their experience with renewables, and their respective outlooks for including renewables in their resource portfolios. Some basic differences exist between wholesale and retail competition that should be recognized when discussing power marketing and renewable power. At the wholesale level, the majority of power marketers stress the commodity nature of electricity. The primary criteria for developing resource portfolios are the same as those of their wholesale customers: the cost and reliability of power supplies. At the retail level, electricity may be viewed as a product that includes value-added characteristics or services determined by customer preferences.

    2017-03-01

    Full Text Available Currently, the Chinese government leads urban renewal via a top-down management style with the government playing the role of decision-maker. The decision-making opinions held by groups of stakeholders are divided, which creates many social problems, project technical issues and even civil disorder. This paper uses factor analysis to extract the key variables for decision-making on urban renewal and the entropy weight method to sort these key variables by importance. Based on this order, the differing opinions of stakeholders regarding urban renewal decision-making are explored. First, contradictory opinions exist concerning the importance of the ecological environment, housing and facilities, social welfare and commercial activities, which are the main driving forces behind urban renewal, due to the groups of stakeholders having different interest demands. Second, these varying interest demands of the stakeholders affect the urban renewal decision-making results. Finally, compensation to people for the demolition of their homes, infrastructure supplements and the investment behaviour of developers display the greatest lack of consensus of all the variables tested in urban renewal decision-making between different stakeholders.

    Climate change and the energy crisis are two of the most significant issues facing our planet today. Recognizing the urgent need for attention, renewable or clean energy started receiving industry focus several years ago, and the momentum picked up over the last decade. Today however, the demand and supply gap continues to be considerable. Although key indicators point to growth in the future, among the key stumbling blocks is financial support. This paper takes a look at the reasons that contribute to the risk, the rewards that the lie in store, and of the recent efforts in this area.

    The topic of the behaviour of energetic alpha particles in magnetic fusion confined plasmas is perhaps the ultimate frontier plasma physics issue that needs to be understood in the quest to achieve controlled power from the fusion reaction in magnetically confined plasmas. The partial pressure of alpha particles in a burning plasma will be ~5-10% of the total pressure and under these conditions the alpha particles may be prone to develop instability through Alfvénic interaction. This may lead, even with moderate alpha particle loss, to a burn quench or severe wall damage. Alternatively, benign Alfvénic signals may allow the vital information to control a fusion burn. The significance of this issue has led to extensive international investigations and a biannual meeting that began in Kyiv in 1989, followed by subsequent meetings in Aspenäs (1991), Trieste (1993), Princeton (1995), JET/Abingdon (1997), Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005), Kloster Seeon (2007) and Kyiv (2009). The meeting was initially entitled 'Alpha Particles in Fusion Research' and then was changed during the 1997 meeting to 'Energetic Particles in Magnetic Confinement Systems' in appreciation of the need to study the significance of the electron runaway, which can lead to the production of energetic electrons with energies that can even exceed the energy produced by fusion products. This special issue presents some of the mature interesting work that was reported at the 12th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems, which was held in Austin, Texas, USA (7-11 September 2011). This meeting immediately followed a related meeting, the 5th IAEA Technical Meeting on Theory of Plasma Wave Instabilities (5-7 September 2011). The meetings shared one day (7 September 2011) with presentations relevant to both groups.

    Renewable energy CDM (RE-CDM) projects encourage cost-effective GHG mitigation and enhanced sustainable development opportunities for the host countries. CERs from CDM projects include the value of the former benefits (i.e., 'climate change benefits'), whereas the second can be given value through the issuing and trading of tradable green certificates (TGCs). Countries could agree to trade these TGCs, leading to additional revenues for the investors in renewable energy projects and, therefore, further encouraging the deployment of CDM projects, currently facing significant barriers. However, the design of a combination of CDM projects and TGC schemes raises several conflicting issues and leads to trade-offs. This paper analyses these issues, identifies the alternatives that may exist to link TGC schemes with RE-CDM projects and analyses the impacts of those options on different variables and actors.

    Full Text Available Following a regional-level study conducted in Fukushima Prefecture, Japan (Wang et al., 2014 [1], this paper presents an approach for municipal renewable energy planning and its experimental application in a Japanese municipality using a Geographic Information System (GIS. The proposed approach is comprised of local issue identification, renewable energy potential evaluation and visualization, site comparison and scenario analysis. GIS was used to analyze and visualize solar, wind and biomass (forest and agriculture residue potential within Kawamata Town, Fukushima, Japan. According to local conditions, all potential sites were coded and then compared based on different criteria, such as solar radiation, wind speed, slope and land uses, among others. In the scenario analysis section, two scenarios, “renewable energy prioritized” and ”evacuation area prioritized”, were adopted and compared. The scenarios are altered in terms of placement and the number of renewable energy facilities inside and outside evacuation areas within the town. The results generated through the proposed approach can provide information on local potentials of renewable energy resources, as well as renewable energy development alternatives at the municipal level. They can be used in the interactive dialogue for the municipal renewable energy planning process, to help to fulfill the municipality’s post-earthquake energy developmental vision.

  7. Renewable Resources, Capital Accumulation, and Economic Growth

    Directory of Open Access Journals (Sweden)

    Wei-Bin Zhang

    2011-01-01

    Full Text Available This paper proposes a dynamic economic model with physical capital and renewable resources. Different from most of the neoclassical growth models with renewable resources which are based on microeconomic foundation and neglect physical capital accumulation, this study proposes a growth model with dynamics of renewable resources and physical capital accumulation. The model is a synthesis of the neoclassical growth theory and the traditional dynamic models of renewable resources with an alternative approach to household behavior. The model describes a dynamic interdependence among physical accumulation, resource change, and division of labor under perfect competition. Because of its refined economic structure, our study enables some interactions among economic variables which are not found in the existing literature on economic growth with renewable resources. We simulate the model to demonstrate the existence of equilibrium points and motion of the dynamic system. Our comparative dynamic analysis shows, for instance, that a rise in the propensity to consume the renewable resource increases the interest rate and reduces the national and production sector’s capital stocks, wage rate and level of the consumption good. Moreover, it initially reduces and then increases the capital stocks of the resource sector and the consumption and price of the renewable resource. The stock of the renewable resource is initially increased and then reduced. Finally, labor is redistributed from the production to the resource sector.

    2015-01-01

    The increasing attention to environmental issues is forcing the implementation of novel energy models based on renewable sources, fundamentally changing the configuration of energy management and introducing new criticalities that are only partly understood. In particular, renewable energies introduce fluctuations causing an increased request of conventional energy sources oriented to balance energy requests on short notices. In order to develop an effective usage of low-carbon sources, such fluctuations must be understood and tamed. In this paper we present a microscopic model for the description and the forecast of short time fluctuations related to renewable sources and to their effects on the electricity market. To account for the inter-dependencies among the energy market and the physical power dispatch network, we use a statistical mechanics approach to sample stochastic perturbations on the power system and an agent based approach for the prediction of the market players behavior. Our model is a data-d...

  9. Stability Enhancement of a Power System Containing High-Penetration Intermittent Renewable Generation

    Directory of Open Access Journals (Sweden)

    Jorge Morel

    2015-06-01

    Full Text Available This paper considers the transient stability enhancement of a power system containing large amounts of solar and wind generation in Japan. Following the Fukushima Daiichi nuclear disaster there has been an increasing awareness on the importance of a distributed architecture, based mainly on renewable generation, for the Japanese power system. Also, the targets of CO2 emissions can now be approached without heavily depending on nuclear generation. Large amounts of renewable generation leads to a reduction in the total inertia of the system because renewable generators are connected to the grid by power converters, and transient stability becomes a significant issue. Simulation results show that sodium-sulfur batteries can keep the system in operation and stable after strong transient disturbances, especially for an isolated system. The results also show how the reduction of the inertia in the system can be mitigated by exploiting the kinetic energy of wind turbines.

    2011-01-01

    There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. In this grid integration, communication systems are crucial technologies, which enable the accommodation of distributed renewable energy generation and play extremely important role in monitoring, operating, and protecting both renewable energy generators and power systems. In this paper, we review some communication technologies available for grid integration of renewable energy resources. Then, we present the communication systems used in a real renewable energy project, Bear Mountain Wind Farm (BMW) in British Columbia, Canada. In addition, we present the communication systems used in Photovoltaic Power Systems (PPS). Finally, we outline some research challenges and possible solutions about the communication systems for grid integration of renewable energy resources.

    Full Text Available Green datacenters has become a major research area among researchers in academy and industry. One of the recent approaches getting higher attention is supplying datacenters with renewable sources of energy, leading to cleaner and more sustainable datacenters. However, this path poses new challenges. The main problem with existing renewable energy technologies is high variability, which means high fluctuation of available energy during different time periods on a day, month or year. In our paper, we address the issue of better managing datacenter workload in order to achieve higher utilization of available renewable energy. We implement an algorithm in CloudSim simulator which decides to postpone or urgently run a specific job asking for datacenter resources, based on job’s deadline and available solar energy. The aim of this algorithm is to make workload energy consumption through 24 hours match as much as possible the solar energy availability in 24 hours. Two typical, clear and cloudy days, are taken in consideration for simulation. The results from our experiments show that, for the chosen workload model, jobs are better managed by postponing or urgently running them, in terms of leveraging available solar energy. This yields up to 17% higher utilization of daily solar energy.

    Full Text Available This paper presents a review about future scenario of renewable energy in India.Energy is a vital input for economic and social development of any country. With increasing industrialand agricultural activities in the country, the demand for energy is also rising. Solar, wind and biomassare accepted as dependable and widely available renewable sources of energy. To meet the energy requirement for such a fast growingeconomy, India will require an assured supply of 3–5 times more energy than the total energy consumedtoday. The renewable energy is one of the options to meet this requirement Energy is the prime mover of economic growth and is vital to the sustenance of a modern economy. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. India has obtained application of a variety of renewable energy technologies for use in different sectors too. This paper presents current status, major achievements and future aspects of renewable energy in India. In this paper evaluation of current energy policies for conquering the obstructions and implementing renewables for the future is also been presented.

    The ability to put cutting edge technology on paper—not in words but in a working physical form—has been attracting an increasing number of researchers over the past decade. Paper has many advantages that make it attractive for flexible electronics: it is relatively environmentally benign; it is renewable; it can be recycled; it is light weight; production processes for paper are well advanced; and it is inexpensive. This special issue, with guest editors Ronald Österbacka from Åbo Akademi University in Finland and Jin-Woo Han from the NASA AMES Research Center, features some of the latest in paper electronics research, including developments towards applications in displays, sensing and alternative energy sources, as well as fundamental studies to further our understanding of how paper can be most effectively used in electronics. As Andrew Steckl and colleagues in the US point out, 'Cellulose-based paper substrates were implemented as an electronic substrate as early as 1969, with most advancement occurring in the past decade largely due to technology improvements in thin film deposition and organic materials' [1, 2]. They report a detailed comparison between paper, standard liquid crystal display rigid glass and flexible glass for hosting pentacene organic thin film transistors, and obtain promising results for future paper-based devices. As most meaningful electronic devices rely on transistors to function, transistors feature quite prominently in this special issue. Rodrigo Martins and colleagues in France and Portugal study the effect of fibre type, structure and dimension on paper-based transistors and reveal further insights into how paper properties affect device performance [3]. Qing Wan and colleagues in China bring the state of the art in transistor technology to paper substrates [4], fabricating indium-zinc-oxide (IZO)-based protonic/electronic hybrid thin film transistors on paper and showing that they can be used as artificial synapses.

    2017-06-01

    Full Text Available Electrical energy is versatile and considered as the back bone of our daily life. It is directly or indirectly used in everyone’s daily activities. But for having the availability of the sources, we cannot but depend on the renewable resources. The renewable resources can be replaced through the natural process at a rate which is equal or greater than this rate at which they are used. Actually, renewable energy is generated from natural resources like sunlight, wind, tide, geothermal heat, ocean energy etc. that are renewable. A prediction is that in 2030, energy comes from renewable sources is 28% of total generation. Though Bangladesh having lots of natural resources, but still now facing and struggling with the shortage of power, while our neighboring countries are utilizing their sources properly and being richer with better economic growth. The vision for increasing economic growth to 10% by 2017 can be come into reality through the proper utilization of renewable energy resources for having a sustainable development of our country. This paper shows an analytical study on recent energy scenario of Bangladesh and describes the potentiality of available renewable energy resources that should be incorporated in the national energy planning.

  18. Renewable Energies: A Fix that Can Backfire?

    Renewable energies are recognized as the main remedy for global warming and energy insecurity issues. While considerable efforts are being put into increasing the share of renewable energies to decarbonize the global energy supply portfolio, the unintended consequences of increased renewable energy production have been overlooked. Using a system of systems (SoS) approach that considers the water-land-energy-economy nexus, this presentation discusses the trade-offs between the sustainability of water, land, energy and economic resources that must not be overlooked in developing sustainable solutions to global warming. It is shown how considering these trade-offs can make some of the renewable energies less attractive. A portfolio risk balancing approach is proposed to develop regional energy supply mixes that balance the overall effects of the energy mix on various resources while taking into account the regional limitations in resource availability. Such energy mixes would include both renewable and non-renewable energies, but would not solve one problem (i.e. global warming) by worsening other problems (e.g., water scarcity, food shortage, economic instability).

  19. Expert Opinion Analysis on Renewable Hydrogen Storage Systems Potential in Europe

    2016-11-01

    Full Text Available Among the several typologies of storage technologies, mainly on different physical principles (mechanical, electrical and chemical, hydrogen produced by power to gas (P2G from renewable energy sources complies with chemical storage principle and is based on the conversion of electrical energy into chemical energy by means of the electrolysis of water which does not produce any toxic or climate-relevant emission. This paper aims to pinpoint the potential uses of renewable hydrogen storage systems in Europe, analysing current and potential locations, regulatory framework, governments’ outlooks, economic issues, and available renewable energy amounts. The expert opinion survey, already used in many research articles on different topics including energy, has been selected as an effective method to produce realistic results. The obtained results highlight strategies and actions to optimize the storage of hydrogen produced by renewables to face varying electricity demand and generation-driven fluctuations reducing the negative effects of the increasing share of renewables in the energy mix of European Countries.

  20. The Demand Side Management Potential to Balance a Highly Renewable European Power System

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available Shares of renewables continue to grow in the European power system. A fully renewable European power system will primarily depend on the renewable power sources of wind and photovoltaics (PV, which are not dispatchable but intermittent and therefore pose a challenge to the balancing of the power system. To overcome this issue, several solutions have been proposed and investigated in the past, including storage, backup power, reinforcement of the transmission grid, and demand side management (DSM. In this paper, we investigate the potential of DSM to balance a simplified, fully renewable European power system. For this purpose, we use ten years of weather and historical load data, a power-flow model and the implementation of demand side management as a storage equivalent, to investigate the impact of DSM on the need for backup energy. We show that DSM has the potential to reduce the need for backup energy in Europe by up to one third and can cover the need for backup up to a renewable share of 67%. Finally, it is demonstrated that the optimal mix of wind and PV is shifted by the utilisation of DSM towards a higher share of PV, from 19% to 36%.

    Directory of Open Access Journals (Sweden)

    Ester Foppa-Pedretti

    2010-06-01

    Full Text Available This paper discusses some considerations and advances a number of proposals about the potential of Agricultural Engineering to contribute to the field of renewable energy, with an emphasis on biomass. Several areas for action are identified. First, general education and teaching of students who will go on to become technicians and professionals in the sector of renewable energies, even though the characteristics of the sectors are still fuzzy. Diffusion of the energy culture, a too often neglected aspect that is however indispensable to sustain the overdue penetration of renewable energies in Italy, is an additional area for action. Another critical area, energy planning, is currently viewed mainly as involving the assessment on more or less wide areas of energy consumption and for the scope of replacing fossil resources with renewables to meet some energy requirements. A more complex, overarching issue is energy efficiency, especially of buildings, which should be a mainstay of the planning process but is in fact not so clearly addressed in development plans for renewables. At this same level, all interactions among production sectors should be assessed, to enhance the role of agriculture, one of the new potential energy-producing sectors and one of the possible prospective suppliers of renewable energy for different final users, from households to the service sector and industry. Agricultural Engineering has the skills needed to implement all these different actions. A role for it in advanced research, i.e. biotechnologies, can and should also be envisaged. Its work in the renewable energy sector should closely involve microbiological, genetic, chemical, agronomic, and animal research to define the goals to be pursued and to implement intuitions. In this way, Agricultural Engineering would increasingly be characterized as Biosystems Engineering.

    The Atomic Papers annotates over 800 books published since 1945 and approximately 300 periodical articles since 1980 on every facet of the nuclear dilemma: the development and effects of the bomb, the arms race, nuclear proliferation, and the peace movement. Work on both sides of the nuclear power controversy also receives substantial attention. All references are to English-language material, and nearly half are to work published since 1980. The concluding chapter, ''The Art of Fission,'' describes over one hundred novels and stories with nuclear themes published since 1945--and, in a few cases, before that date.

    2007-01-01

    At the 2003 meeting of the Directing Council of the Pan American Health Organization (PAHO), the PAHO Member States issued a mandate to strengthen primary health care (Resolution CD44. R6). The mandate led in 2005 to the document "Renewing Primary Health Care in the Americas. A Position Paper of the Pan American Health Organization/WHO [World Health Organization]," and it culminated in the Declaration of Montevideo, an agreement among the governments of the Region of the Americas to renew their commitment to primary health care (PHC). Scientific data have shown that PHC, regarded as the basis of all the health systems in the Region, is a key component of effective health systems and can be adapted to the range of diverse social, cultural, and economic conditions that exist. The new, global health paradigm has given rise to changes in the population's health care needs. Health services and systems must adapt to address these changes. Building on the legacy of the International Conference on Primary Health Care, held in 1978 in Alma-Ata (Kazakhstan, Union of Soviet Socialist Republics), PAHO proposes a group of strategies critical to adopting PHC-based health care systems based on the principles of equity, solidarity, and the right to the highest possible standard of health. The main objective of the strategies is to develop and/or strengthen PHC-based health systems in the entire Region of the Americas. A substantial effort will be required on the part of health professionals, citizens, governments, associations, and agencies. This document explains the strategies that must be employed at the national, subregional, Regional, and global levels.

  5. Consortium for Electric Reliability Technology Solutions Grid of the Future White Paper on Review of Recent Reliability Issues and Systems Events

    Energy Technology Data Exchange (ETDEWEB)

    Hauer, John F.; Dagle, Jeffery E.

    1999-12-01

    This report is one of six reports developed under the U.S. Department of Energy (DOE) program in Power System Integration and Reliability (PSIR). The objective of this report is to review, analyze, and evaluate critical reliability issues demonstrated by recent disturbance events in the North America power system. Eleven major disturbances are examined, most occurring in this decade. The strategic challenge is that the pattern of technical need has persisted for a long period of time. For more than a decade, anticipation of market deregulation has been a major disincentive to new investments in system capacity. It has also inspired reduced maintenance of existing assets. A massive infusion of better technology is emerging as the final option to continue reliable electrical services. If an investment in better technology will not be made in a timely manner, then North America should plan its adjustments to a very different level of electrical service. It is apparent that technical operations staff among the utilities can be very effective at marshaling their forces in the immediate aftermath of a system emergency, and that serious disturbances often lead to improved mechanisms for coordinated operation. It is not at all apparent that such efforts can be sustained through voluntary reliability organizations in which utility personnel external to those organizations do most of the technical work. The eastern interconnection shows several situations in which much of the technical support has migrated from the utilities to the Independent System Operator (ISO), and the ISO staffs or shares staff with the regional reliability council. This process may be a natural and very positive consequence of utility restructuring. If so, the process should be expedited in regions where it is less advanced.

  6. Renewable Energy Auctions and Tenders: How good are they?

    Directory of Open Access Journals (Sweden)

    David Toke

    2015-06-01

    Full Text Available This paper analyses the performance of two cases of renewable energy (RE auction/tender systems in an effort to contribute to the evaluation of RE auction/tender systems and to study best practice in their delivery of RE projects. This is done by comparing regimes in different settings, one concerned with Danish offshore wind development, the other concerned with renewable energy development in South Africa. It is found that regulatory factors which promote certainty in deployment, including measures to ensure that projects achieve grid connection, are important in assuring delivery of the programmes. However cost reductions that are associated with renewable energy auctions are not caused mainly by the auction systems themselves, but rather are associated with general declines in the costs of renewable energy technologies. Moreover, the effect of renewable energy auctions systems may be more concerned with limiting renewable energy deployment rather than reducing the costs of energy generated by renewable energy projects that are deployed.

    This article relates the case of two young girls who became pregnant as a result of rape and their efforts to exercise their rights to terminate the pregnancy. The first victim was a 12-year-old girl from Bolivia and the second was Paulina, a 13-year-old resident of Baja California, Mexico. Though abortion is illegal in both countries, in the case of rape the procedure is "unpunishable" in Bolivia and legal in Mexico. Despite these laws, the girls, their families and their advocates contend repeatedly with local government and Catholic Church officials on the issue. Only the first victim successfully exercised her right to terminate her pregnancy through the efforts of her family and the decision of Penal Judge Luis Ledezma. This paper also highlights the need for reforms in the abortion law in both countries.

    Global energy crisis and limited supply of petroleum fuels have rekindled the worldwide focus towards development of a sustainable technology for alternative fuel production. Utilization of abundant renewable biomass offers an excellent opportunity for the development of an economical biofuel production process at a scale sufficiently large to have an impact on sustainability and security objectives. Additionally, several environmental benefits have also been linked with the utilization of renewable biomass. Butanol is considered to be superior to ethanol due to its higher energy content and less hygroscopy. This has led to an increased research interest in butanol production from renewable biomass in recent years. In this paper, we review the various aspects of utilizing renewable biomass for clostridial butanol production. Focus is given on various alternative substrates that have been used for butanol production and on fermentation strategies recently reported to improve butanol production.

    The aim of this paper is to present the Brazilian experience to encourage renewable sources of power generation through the auctions into the Regulated Environment of Contracting. These auctions are subdivided into auctions of existing plants, new plants, alternative sources and structural plants. In this process we observe the structure of the mechanism for contracting new projects of renewable sources without neglecting the low tariffs issues. Thus, the auctions of electricity in Brazil is an alternative to be considered in an attempt to group market mechanisms, low tariffs and incentives to renewable sources of generation. (author)

    1992-01-01

    Federal involvement in simulating economic growth through the development and application of technology policy is currently the subject of serious debate. A recession and the recognition that an internationally competitive economy is a prerequisite for the attainment of national goals have fostered a number of technology policy initiatives aimed at improving the economic competitiveness of American industry. This paper suggests that the successful implementation of U.S. technology policy will require the adoption of a knowledge diffusion model, the development of user oriented information products and services, and a more 'activist' approach on the part of sci/tech librarians in the provision of scientific and technical information (STI). These changes will have a dramatic impact on the sci/tech library of the future and the preparation of sci/tech librarians.

This review mainly introduces our recent work on the transformation of renewable carbon resources including the conversion of cellulose, lignin, and chitin into sustainable chemicals. Various transformation routes have been established to form value-added chemicals, and accordingly a variety of effective catalytic systems have been developed, either based on metal catalysis and/or acid-base catalysis, to enable the desired transformation.

    Urban and neighbourhood renewal in Denmark first became of public interest and the subject of legislation in the early twentieth century. Concern was based on health, fire and sanitation issues with the focus on the condition of individual dwellings. It was not until the early 1940s that the first...... urban quarter in Copenhagen was renewed through demolition and rebuilding. Based on legislation from 1939, with revisions in 1959 and 1969, the slum clearance approach was strongly criticised for disrupting local life and destroying cultural assets. It was not until 1983 that more sensitive policies...

    Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface. The favourable features of nanostructures for catalysis

    2011-07-01

    This paper explores the relationships between climate policy and renewable energy policy instruments. It shows that, even where CO2 emissions are duly priced, specific incentives for supporting the early deployment of renewable energy technologies are justified by the steep learning curves of nascent technologies. This early investment reduces costs in the longer term and makes renewable energy affordable when it needs to be deployed on a very large scale to fully contribute to climate change mitigation and energy security. The paper also reveals other noteworthy interaction effects of climate policy and renewable policy instruments on the wholesale electricity prices in deregulated markets, which open new areas for future research.

    2009-12-15

    China is now the largest CO{sub 2} polluter in the world. However, the renewable energy policies in China are controversial and one can easily draw the wrong conclusions that Chinese renewable energy development has taken off from a surface assessment of the policies. By investigating and summarizing the first-hand experiences of participation in the Chinese renewable market (mainly wind farm development) in the past five years, this paper provides another dimension of policy analysis and independent review of the current issues facing the market. An investigation of policy changes and consequences clearly demonstrates the transformation of the Chinese renewable market. The domestic manufacturing quality and unprofessional design of wind farms made most developers' financial returns unrealistic in the wind market. Despite the difficulties and inconsistency in the system, China is tackling environmental issues seriously and heading in the right direction. With centrally controlled management, the Chinese strategies do not have to be justified financially. It is envisioned by the authors that re-organizing over 70 existing Chinese wind turbine manufacturers is unavoidable. Establishment of an internal renewable market, such as Renewable Obligation Certificate (ROC) system in the UK whose effectiveness is another subject of debate, would be an effective means by which the Chinese government in their post-2012 strategy could make the wind market more financially viable.

    This multidisciplinary research is focused on studying implementation of diverse renewable energy networks. Our modern economy now depends heavily on large-scale, energy-intensive technologies. A transition to low carbon, renewable sources of energy is needed. We will develop a procedure for designing and analyzing renewable energy systems based on the magnitude, distribution, temporal characteristics, reliability and costs of the various renewable resources (including biomass waste streams) in combination with various measures to control the magnitude and timing of energy demand. The southern Canadian prairies are an ideal location for developing renewable energy networks. The region is blessed with steady, westerly winds and bright sunshine for more hours annually than Houston Texas. Extensive irrigation agriculture provides huge waste streams that can be processed biologically and chemically to create a range of biofuels. The first stage involves mapping existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation, such as ridges, rooftops and valley walls, will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids.

    Man, language and existence: Five queries about Heidegger's view of language (p. 803) HU Zhuanglin (English Dept., Peking University, Beijing 100871, China) The late German philosopher Heidegger was well-known for his criticism on the long- standing tradition of formalism and rationalism represented by Plato and Aristotle from the per- spectives of existentialism, phenomenology and hermeneutics, and his argument that language di- rects man. All this has been highly recognized by modem western philosophers. However, several points of his view of language need further clarification and discussion, such as inexplicitness of his writing style, word's archaeological meaning as his principle of argument, the relation between language and science/technology, the meaning of "God" in the schema of "heaven, land, God, man", and the unity of natural language and human language. The present writer attempts to answer some of the questions and expresses his own views.

    2007-04-17

    Twenty-one states and the District of Columbia have adopted mandatory renewables portfolio standards (RPS) over the last ten years. Renewable energy attributes-such as the energy source, conversion technology, plant location and vintage, and emissions-are usually required to verify compliance with these policies, sometimes through attributes bundled with electricity, and sometimes with the attributes unbundled from electricity and traded separately as renewable energy certificates (RECs). This report summarizes the treatment of renewable energy attributes in state RPS rules. Its purpose is to provide a source of information for states considering RPS policies, and also to draw attention to certain policy issues that arise when renewable attributes and RECs are used for RPS compliance. Three specific issues are addressed: (1) the degree to which unbundled RECs are allowed under existing state RPS programs and the status of systems to track RECs and renewable energy attributes; (2) definitions of the renewable energy attributes that must be included in order to meet state RPS obligations, including the treatment of available emissions allowances; and (3) state policies on whether renewable energy or RECs sold through voluntary green power transactions may count towards RPS obligations.

  1. Renewable Electricity Futures. Operational Analysis of the Western Interconnection at Very High Renewable Penetrations

    Energy Technology Data Exchange (ETDEWEB)

    Brinkman, Gregory [National Renewable Energy Lab. (NREL), Golden, CO (United States)

    2015-09-01

    The Renewable Electricity Futures Study (RE Futures)--an analysis of the costs and grid impacts of integrating large amounts of renewable electricity generation into the U.S. power system--examined renewable energy resources, technical issues regarding the integration of these resources into the grid, and the costs associated with high renewable penetration scenarios. These scenarios included up to 90% of annual generation from renewable sources, although most of the analysis was focused on 80% penetration scenarios. Hourly production cost modeling was performed to understand the operational impacts of high penetrations. One of the conclusions of RE Futures was that further work was necessary to understand whether the operation of the system was possible at sub-hourly time scales and during transient events. This study aimed to address part of this by modeling the operation of the power system at sub-hourly time scales using newer methodologies and updated data sets for transmission and generation infrastructure. The goal of this work was to perform a detailed, sub-hourly analysis of very high penetration scenarios for a single interconnection (the Western Interconnection). It focused on operational impacts, and it helps verify that the operational results from the capacity expansion models are useful. The primary conclusion of this study is that sub-hourly operation of the grid is possible with renewable generation levels between 80% and 90%.

They also identify the materials and processes most relevant to infrastructure renewal, and discuss product and process improvements as well as specifications and standardization.

  3. Siting Conflicts in Renewable Energy Projects in Sweden: Experiences From the Siting of a Biogas Plant

    Energy Technology Data Exchange (ETDEWEB)

    Khan, Jamil

    2001-05-01

    This paper seeks to contribute to an increased understanding of what characterises conflicts regarding the siting of renewable energy facilities. The paper starts out with a brief introduction to different types of renewable energy and the conflicts they might generate as well as a discussion about the differences and similarities in comparison with conflicts over more controversial issues, such as nuclear plants, chemical factories and the construction of roads. The main part of the paper discusses the results from a case study on a failed attempt to site a biogas plant in southern Sweden. The results show that there was a lack of public participation in the early stages of planning, and that peoples negative perceptions of the possibilities to influence the decision-making and of the attitude of the developer, contributed to the development of a public opposition and a polarisation of the conflict. There is also a discussion about the reasons for a shift in the political support for the project and about the role of the legislation in shaping planning processes that either handle conflicts or make them worse. The paper concludes with the observation that the biogas case, in many ways, resembled traditional siting conflicts and that further research is needed to explore the nature of different renewable energy siting conflicts.

    Full Text Available Following the already proved models the sustainable planning culture is endangering several methods directed towards the needs of tenants in the existing post-war housing stock. The case-study of our project is the renewal of the multi stored building in the housing estate Metalna, Maribor/Tezno (1949. It is based on the sustainable renovation principle for the quality of sustainable housing in functional, technological and environmental point of view. According to it, the idea of the project was to improve the functionality of the building as well as of individual housing units. One of the main goals was to introduce the variety of space and typology of individual housing units. Beside, there was an intention to rebuild and redesign the green area, especially the problems of parking and playground for children. On the other hand, the project is introducing the low-energy renovation principle including new technologies, structural elements and materials. Two scenarios of technological renewal were suggested. The first one was a classical one using additional thermal insulation of the building envelope and fitting of new structural elements such as windows, doors, balconies, windbreaks etc. (Renewal 1. The second scenario, however, included the sunspace construction used as a new passive solar structural element, modifying the envelope (Renewal 2. The energy efficiency of the suggested scenarios were calculated according to the procedures given in EN 832 standard considering the attached sunspace as integral part of the building in first case and as a passive solar object adjacent to the thermal envelope of the building in the second case. The results show that the last case yields the most energy efficient renewal of the existing residential building.

    A Delphi Survey is a series of questionnaires that allow experts or people with specific knowledge to develop ideas about potential future developments around an issue. The Delphi questionnaires were developed throughout the foresight process in relation to the responses given by participants in bibliometric and SWOT analysis conducted prior to the Delphi survey. In this paper, Turkey's renewable energy future is evaluated using the Delphi method. A two-round Delphi research study was undertaken to determine and measure the expectations of the sector representatives regarding the foresight of renewable energies. First and second round of Delphi study were carried out by using online surveys. About 382 participants responded in the first round of the Delphi questionnaire yielding a respond rate of 20.1%, whereas 325 participants responded at the second round yielding a respond rate of 84.9%. About 50% of Turkey's energy demand was foresighted to be met by renewable energies around 2030. The results showed that all types of renewable energies would not only provide economic and environmental benefits but also improve living standards. (author)

    Designing eco-friendly system has been at the forefront of computing research. Faced with a growing concern about the server energy expenditure and the climate change, both industry and academia start to show high interest in computing systems powered by renewable energy sources. Existing proposals on this issue mainly focus on optimizing resource utilization or workload performance. The key supporting hardware structures for cross-layer power management and emergency handling mechanisms are often left unexplored. This paper presents GreenPod, a research framework for exploring scalable and dependable renewable power management in datacenters. An important feature of GreenPod is that it enables joint management of server power supplies and virtualized server workloads. Its interactive communication portal between servers and power supplies allows datacenter operators to perform real-time renewable energy driven load migration and power emergency handling. Based on our system prototype, we discuss an important topic: virtual machine (VM) workloads survival when facing extended utility outage and insuffcient onsite renewable power budget. We show that whether a VM can survive depends on the operating frequencies and workload characteristics. The proposed framework can greatly encourage and facilitate innovative research in dependable green computing.

    2011-02-01

    Energy is a significant cost in the economics of desalinating waters, but water scarcity is driving the rapid expansion in global installed capacity of desalination facilities. Conventional fossil fuels have been utilized as their main energy source, but recent concerns over greenhouse gas (GHG) emissions have promoted global development and implementation of energy minimization strategies and cleaner energy supplies. In this paper, a comprehensive review of energy minimization strategies for membrane-based desalination processes and utilization of lower GHG emission renewable energy resources is presented. The review covers the utilization of energy efficient design, high efficiency pumping, energy recovery devices, advanced membrane materials (nanocomposite, nanotube, and biomimetic), innovative technologies (forward osmosis, ion concentration polarization, and capacitive deionization), and renewable energy resources (solar, wind, and geothermal). Utilization of energy efficient design combined with high efficiency pumping and energy recovery devices have proven effective in full-scale applications. Integration of advanced membrane materials and innovative technologies for desalination show promise but lack long-term operational data. Implementation of renewable energy resources depends upon geography-specific abundance, a feasible means of handling renewable energy power intermittency, and solving technological and economic scale-up and permitting issues.

    2013-09-01

    In the U.S., a number of utilities are adopting higher penetrations of renewables, driven in part by state policies. While power systems have been designed to handle the variable nature of loads, the additional supply-side variability and uncertainty can pose new challenges for utilities and system operators. However, a variety of operational and technical solutions exist to help integrate higher penetrations of wind and solar generation. This paper explores renewable energy integration challenges and mitigation strategies that have been implemented in the U.S. and internationally, including forecasting, demand response, flexible generation, larger balancing areas or balancing area cooperation, and operational practices such as fast scheduling and dispatch.

    2011-01-01

    This paper describes a new method for generating stationary integer-valued time series from renewal processes. We prove that if the lifetime distribution of renewal processes is nonlattice and the probability generating function is rational, then the generated time series satisfy causal and invertible ARMA type stochastic difference equations. The result provides an easy method for generating integer-valued time series with ARMA type autocovariance functions. Examples of generating binomial ARMA(p,p-1) series from lifetime distributions with constant hazard rates after lag p are given as an illustration. An estimation method is developed for the AR(p) cases.

  8. Financing renewable energy for Village Power application

    1997-12-01

    When one talks of rural development, no doubt, the issue of rural energy is not far behind. As a significant component of any development strategy, rural energy is seen as the engine for growth that can bring about economic upliftment in the countryside. Many approaches to rural energy development have been tried. These approaches differ from country to country. But regardless of structure and approach, the goal remain essentially the same: to provide rural communities access to reliable energy services at affordable prices. In recent years, as global concern for the environment has increased, many governments have turned to renewable energy as a more environment friendly alternative to rural electrification. Technological advances in renewable energy application has helped to encourage this use. System reliability has improved, development costs have, to some extent been brought down and varied application approaches have been tried and tested in many areas. Indeed, there is huge potential for the development of renewable energy in the rural areas of most developing countries. At the rural level, renewable energy resources are almost always abundantly available: woodwaste, agricultural residues, animal waste, small-scale hydro, wind, solar and even sometimes geothermal resources. Since smaller scale systems are usually expected in these areas, renewable energy technologies can very well serve as decentralized energy systems for rural application. And not only for rural applications, new expansion planning paradigms have likewise led to the emergence of decentralized energy systems not only as supply options but also as corrective measures for maintaining end of line voltage levels. On the other hand, where renewable energy resource can provide significant blocks of power, they can be relied upon to provide indigenous power to the grids.

  11. Utilizing GIS to Examine the Relationship Between State Renewable Portfolio Standards and the Adoption of Renewable Energy Technologies

    Directory of Open Access Journals (Sweden)

    Chelsea Schelly

    2013-12-01

    Full Text Available In the United States, there is no comprehensive energy policy at the federal level. To address issues as diverse as climate change, energy security, and economic development, individual states have increasingly implemented Renewable Portfolio Standards (RPSs, which mandate that utility providers include a specified amount of electricity from renewable energy sources in their total energy portfolios. Some states have included incentives for individual energy technologies in their RPS, such as solar electric (also called photovoltaic or PV technology. Here, we use GIS to visualize adoption of RPSs and electricity generation from renewable energy sources in the US and examine changes in renewable electricity and solar electric generation over time with the goal of informing future policies aimed at promoting the adoption of renewable energy technologies.

    Directory of Open Access Journals (Sweden)

    RADULESCU IRINA GABRIELA

    2015-06-01

    Full Text Available The states from European Union must take advantage from renewable energy sources in order to revive the economy. Climate change creates new jobs and could reduce energy imports which would stimulate the economy of those states. The European Union should support research in the field, apply more efficient policies in energy, and create economies of scale to get an integrated European energy market in which the main actors can reduce the cost of production of renewable energy. In addition, it is possible to use the comparative advantages of the Member States and not only, like Greece, through solar energy, Southern Mediterranean, through distribution networks interconnections with EU, Russia and Ukraine, through biomass and the North Sea, through wind energy. This paper refers to the evolution and trends of the renewable energy sources and presents some scenarios of it.

    2016-11-01

    Time Warner Cable (TWC), now Charter Communications (CC), partnered with the National Renewable Energy Laboratory (NREL) to assess the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat-pump systems at 696 TWC facilities. NREL identified 306 sites where adding a renewable energy system would provide cost savings over the project life-cycle. In general, the top sites have some combination of high electricity rates ($0.16-$0.29/kWh), significant state incentives, and favorable net-metering policies. If all projects were implemented via third-party power purchase agreements, TWC/CC would save $37 million over 25 years and meet 10.5% of their energy consumption with renewable energy. This paper describes the portfolio screening methodology used to identify and prioritize renewable energy opportunities across the TWC sites, as well as a summary of the potential cost savings that may be realized by implementing these projects. This may provide a template for other companies interested in identifying and prioritizing renewable energy opportunities across a large number of geographically dispersed sites. Following this initial portfolio analysis, NREL will be conducting in-depth analysis of project development opportunities at ten sites and evaluating off-grid solutions that may enable carbon emission reduction and grid independence at select facilities.

    Increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries' strategies to achieve reductions in greenhouse gas emissions. However, renewable energy investments can often have external costs and benefits, which need to be taken into account if socially optimal investments are to be made. This paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in Scotland, a country which has set particularly ambitious targets for expanding renewable energy. The external effects we consider are those on landscape quality, wildlife and air quality. We also consider the welfare implications of different investment strategies for employment and electricity prices. The methodology used to do this is the choice experiment technique. Renewable technologies considered include hydro, on-shore and off-shore wind power and biomass. Welfare changes for different combinations of impacts associated with different investment strategies are estimated. We also test for differences in preferences towards these impacts between urban and rural communities, and between high- and low-income households. (author)

    In Europe, the integration of decentralized renewable energy production in regional planning processes plays a crucial role. In particular, regions face a major challenge in order to set up renewable decentralized energy systems and incorporate them into the electricity grid. This paper presents a methodological concept and preliminary tests of applications in order to create an optimization model for an improved renewable energy development and planning practice: firstly, the energy potentials of micro renewable resources are estimated, and secondly the outcomes are combined with an estimation of resulting environmental impacts. Including these data into the spatial analysis, different scenarios can be developed in order to support decision making in landscape planning on the basis of environmental and landscape criteria as well as energy issues, including technical aspects and costs. The case study area is the Hannover region. First results show good energy potentials, which will be in a next step evaluated and combined with environmental impacts in order to improve energy efficiency by integrated renewable, decentralized power plants and energy mix.

    Andersen, Morten Thøtt; Frigaard, Peter Bak

    2015-01-01

    Most of today’s renewable energy systems rely heavily on investments as well as public financial support. This support is often given by means of a higher sales price for each kWh produced, i.e. feed-in tariffs (FITs), green certificates or Renewable Obligation Certificates (ROCs), or by a fixed...... amount, being a percentage of the construction costs of the facility. All these ways of financing have different downsides. The feed-in tariff based kWh prices have some incentives to improve the technology, but enables infeasible solutions to stay financially supported even while R&D is in status quo....... The fixed amount only helps with installation costs, which should not be an issue once the technology is sufficiently feasible. This means that the current ways of granting financial support all lack incentives for increasing production or decreasing construction costs. This paper presents a unique scheme...

    2008-10-15

    Increase in global exploration and production have caused a reduction in offshore exploration licences. This paper outlined the government of Nova Scotia's offshore renewal plan. The plan was designed to clarify the role of the government and the Canada-Nova Scotia Offshore Petroleum Board (CNSOPB) and federal government. The plan was comprised of 4 different sections, including (1) geoscience, (2) new policy, (3) regulation, and (4) investment abstraction. Requests for proposals are now being designed to develop a better understanding of the geology of offshore Nova Scotia, including the shelf slope and deep water areas in the vicinity of Sable Island. A code of practice is currently being developed to minimize the impact of resource development on the marine environment while supporting the economic development of smaller oil and gas discoveries. Resource and analysis packages are currently being developed to help investors compute the risks associated with developing offshore sites. It was concluded that early action is required to address challenges and knowledge gaps related to geological data, regulatory efficiency, policy, and marketing strategies. Success of the plan will require the continued cooperation, and support of various governmental agencies. Details of regulatory renewal initiative projects were included. 1 fig.

  5. Path Renewal Method in Filtering Based Wireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available In applications of wireless sensor networks, there are many security issues. Attackers can create false reports and transmit the reports to the networks. These false reports can lead not only false alarms, but also the depletion of limited energy resources. In order to filter out such false reports during the forwarding process, Ye et al. proposed the statistical en-route filtering (SEF. Several research efforts to enhance the efficiency of SEF have been made. Especially, the path selection method proposed by Sun et al. can improve the detection power of SEF by considering the information on the filtering keys of and distances of upstream paths. However, such selection mechanism could lead to favored paths in heavy traffic, which would result in unbalanced energy consumption. In this paper, we propose a path renewal method to provide load balancing for sensor networks in terms of energy consumption. In our method, a node renews its upstream path to save energy resources if the remaining energy of and the communication traffic of the node exceed some threshold values. We show the effectiveness of the proposed method in terms of balanced energy consumption and filtering power by providing simulation results.

    Public opposition to the siting of renewable energy (RE) facilities and public reluctance to invest in RE remain key obstacles to the expansion of the renewables sector in the UK and a number of other European countries. Although there is a growing body of qualitative research on factors that inform public attitudes towards RE, the majority of studies have tended to be quantitative and to view 'the public' and 'public opinion' as homogeneous wholes. This study uses a cultural theory framework and focus groups conducted in the South West UK to develop deeper understandings of how individuals' worldviews can inform opinions and behaviour in relation to RE. These findings are used to explore ways in which government policies on RE might be tailored to engender greater public support and participation. Issues discussed include the provision of economic incentives, information on climate change and RE, linking renewables to overall energy behaviour, and landscape aesthetics.

    2015-04-01

    The growth in environmental pollution alongside an increasing demand for electricity in Kazakhstan calls for a higher level of renewable energy penetration into national power systems. Kazakhstan has great potential for renewable energies from wind, solar, hydro and biomass resources that can be exploited for electricity production. In 2013, the Kazakhstani Ministry of Energy initiated a new power development plan, which aims to bring the share of renewable energy to 3% by 2020 rising to 30% by 2030 and 50% by 2050. The current contribution of renewable energy resources in the national electricity mix, however, is less than 1%. As a developing country, Kazakhstan has faced a number of barriers to increase renewable energy use, which have to be analysed and translated into a comprehensive renewable energy policy framework. This study presents an overview of the current conditions of renewable energy development in Kazakhstan. Secondly, it identifies and describes the main barriers that prevent diffusion of renewable energy technologies in Kazakhstan. Finally, the paper provides solutions to overcome specific barriers in order to successfully develop a renewable energy technology sector in Kazakhstan.

    Full Text Available The purpose of this paper is to estimate the impact of renewable energy consumption from combustible renewable and waste sources on economic growth in emerging countries. We analyze the stylized facts of renewable energy and emerging countries related to four regions (Africa, Europe, Latin America, and Asia. We use recent data in the cob-Douglas function and applying a non-stationary panel model for 15 emerging countries covering the period (1990-2011. The Granger causality test showed that there is no causal relationship between renewable energy consumption of combustible renewable and waste sources and economic growth that confirm the neutrality hypothesis. The results supported a positive and significant effect of renewable energy consumption of this source on economic growth in emerging countries. The absence of a causal relationship can be explained by the inefficient use of combustible renewable and waste in the majority of those emerging countries. The consumption of low variability renewable energy such as renewable and waste stimulates economic growth in emerging countries.

    The author summarizes changes which have occurred in Bolivia in the past year which have had an impact on renewable energy source development. Political changes have included the privatization of power generation and power distribution, and resulted in a new role for state level government and participation by the individual. A National Rural Electrification Plan was adopted in 1996, which stresses the use of GIS analysis and emphasizes factors such as off grid, economic index, population density, maintenance risk, and local organizational structure. The USAID program has chosen to stress economic development, environmental programs, and health over village power programs. The national renewables program has adopted a new development direction, with state projects, geothermal projects, and private sector involvement stressed.

    This special issue of Fluid Dynamics Research includes nine papers which are based on nine of the presentations at the Second UK-Japan bilateral Workshop and First ERCOFTAC Workshop on 'Turbulent flows generated/designed in multiscale/fractal ways: fundamentals and applications' held from 26 to 27 March 2012 at Imperial College London, UK. The research area of fractal-generated turbulent flows started with a chapter published in 2001 in one of the conference proceedings which came out of the 1999 Isaac Newton Institute 6 month Programme on Turbulence in Cambridge (UK). However, the first results which formed the basis of much of the work reported in this special issue started appearing from 2007 onwards and progress since then could perhaps be described as not insignificant. Research in this area has resulted in the following six notable advances: (a) the definition of two new length-scales characterizing grid-generated turbulence; (b) enhanced and energy-efficient stirring and scalar transfer by fractal grid and fractal openings/flanges with applications, in particular, to improved turbulence generation for combustion; (c) the non-equilibrium turbulent dissipation law; (d) non-equilibrium axisymmetric wake laws; (e) insights into the dependence of drag forces and vortex shedding on the fractal geometry of fractal objects and simulation methods for the calculation of drag of fractal trees; and (f) the invention and successful proof of concept of fractal spoilers and fractal fences. The present special issue contains papers directly related to these advances and can be seen as a reflection of the current research in the field of fractal-generated turbulent flows and their differences and commonalities with other turbulent flows. The financial support from the Japan Society for the Promotion of Science has been decisive for the organization and success of this workshop. We are also grateful to ERCOFTAC who put in place the EU-wide Special Interest Group on multiscale

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed.

    Latvia is among those countries that do not have gas, coal and, for the time being, also oil resources of its own. The amount of power produced in Latvia does not meet the demand, consequently a part of the power has to be purchased from neighbouring countries. Firewood, peat and hydro resources are the only significant domestic energy resources. Massive decrease of energy consumption has been observed since Latvia regained independence. Domestic and renewable energy resources have been examined and estimated. There are already 13 modern boiler houses operating in Latvia with total installed capacity 45 MW that are fired with wood chips. Latvian companies are involved in the production of equipment. 7 small HPPs have been renewed with the installed capacity 1.85 MW. Wind plant in Ainazi has started its operation, where two modern wind turbines with the capacity of 0.6 MW each have been installed. Mechanism of tariff setting is aligned.

    Credits (RECs). Each REC represents a specified amount of renewable electricity production and provides an offset of environmental externalities associated with non-renewable electricity production. The purpose of this paper is to explore the possible issues with RECs and comparable alternative compliance options. Existing codes have been examined to determine energy equivalence between the energy generation requirement and the RECs alternative over the life of the building. The price equivalence of the requirement and the alternative are determined to consider the economic drivers for a market decision. This research includes case studies that review how the few existing codes have incorporated RECs and some of the issues inherent with REC markets. Section 1 of the report reviews compliance options including RECs, green energy purchase programs, shared solar agreements and leases, and other options. Section 2 provides detailed case studies on codes that include RECs and community based alternative compliance methods. The methods the existing code requirements structure alternative compliance options like RECs are the focus of the case studies. Section 3 explores the possible structure of the renewable energy generation requirement in the context of energy and price equivalence. The price of RECs have shown high variation by market and over time which makes it critical to for code language to be updated frequently for a renewable energy generation requirement or the requirement will not remain price-equivalent over time. Section 4 of the report provides a maximum case estimate for impact to the PV market and the REC market based on the Kaufmann et al. proposed requirement levels. If all new buildings in the commercial sector complied with the requirement to install rooftop PV arrays, nearly 4,700 MW of solar would be installed in 2012, a major increase from EIA estimates of 640 MW of solar generation capacity installed in 2009.

    This report evaluates how and when to best integrate renewable energy requirements into building energy codes. The basic goals were to: (1) provide a rough guide of where we’re going and how to get there; (2) identify key issues that need to be considered, including a discussion of various options with pros and cons, to help inform code deliberations; and (3) to help foster alignment among energy code-development organizations. The authors researched current approaches nationally and internationally, conducted a survey of key stakeholders to solicit input on various approaches, and evaluated the key issues related to integration of renewable energy requirements and various options to address those issues. The report concludes with recommendations and a plan to engage stakeholders. This report does not evaluate whether the use of renewable energy should be required on buildings; that question involves a political decision that is beyond the scope of this report.

    Fossil energy shortage and the goals of energy-saving and emission reduction are making it imperative to make adjustment in energy development strategies.With the large-scale connection to new energy generation,traditional power grids are evolving into alternate electrical power systems to,challenge their operational control.As a category of virtual controllable resource,introducing demand-side response (DR) can effectively overcome the problem of intermittency of new energy generation,while improving the utilization efficiency in the grids.Therefore,it is an important issue worth further discussion. This paper firstly introduces the basic features and implication of alternate electrical power systems with renewable energy sources.Then the potential contribution and effects of different demand side resources in such systems are treated according to their inherent characteristics.The enabling technologies of DR and the information about their application across the world are also summarized.On this basis,the status quo concerning DR studies in alternate electrical power systems is analyzed from five facets:planning,operation,control,evaluation,and market mechanism.Subsequently,we analyze the nodus that existed and point out the research directions worth further exploration in the above fields.Finally,based on the actual conditions of China,some suggestions are put forward for commercial application of DR and its safeguard mechanism in the context of the new energy era.%化石能源短缺和节能减排的双重压力促使中国能源发展方式亟待转型调整。随着新能源发电的规模化并网应用,传统电网正在逐步向着新能源电力系统方向演变,并对其运行控制带来显著的影响。作为一类虚拟可控资源,在新能源电力系统中考虑需求侧响应(DR)可有效克服新能源发电的间歇性问题,提高电网对新能源的利用效率,实现源荷互动与协同增效。文

    This paper discusses the reasons for the national and international renewed interest in the concept of MHD seawater propulsion. The main advantages of this concept are presented, together with some of the technical challenges that need to be overcome to achieve reliability, performance, and stealth. The paper discusses in more detail some of the technical issues and loss mechanisms influencing the thruster performance in terms of its electrical efficiency. Among the issues discussed are the jet losses and nozzle efficiency. Ohmic losses and frictional losses inside the thruster. Also discussed are the electrical end losses caused by the fringing magnetic field near the end of the electrodes. It has been shown that the frictional and end losses can have strong adverse effects on the thruster performance. Furthermore, a parametric study has been performed to investigate the effects of several parameters on the performance of the MHD thrusters. Those parameters include the magnetic field, thruster diameter, all roughness, flow velocity, and electrical load factor. The results of the parametric study indicate that the thruster efficiency increases with the strength of the magnetic field and thruster diameter, and decreases with the wall roughness and the flow velocity. 8 refs., 8 figs.

    The utilisation of biomass poses large challenges in renewable energy systems while buildings account for a substantial part of the energy supply even in 100% renewable energy systems. In this paper the focus is on how the heating sector can reduce its consumption of biomass, thus leaving biomass...... for other sectors, but while still enabling a 100% renewable energy system. The analyses of heating technologies shows that district heating (DH) systems are important in limiting the dependence on biomass and create cost effective solutions. DH systems are especially important in renewable energy systems...... with large amounts of fluctuating sources as it enables fuel efficient and low cost energy systems with thermal heat storages. DH increases the efficiency with the use of combined heat and power production (CHP), while reducing the biomass demand by enabling the use of other renewable resources such as large...

    This paper attempts to compare the research output and priorities of 25 major countries in renewable energy research. The main objective is to assess the research priorities of the major countries in frontier areas/subjects of renewable energy using some bibliometric measures based on renewable energy literature. Subjects of high activity and subjects of low activity are identified for two time periods (1996-1997 and 1998-1999). Our findings show that the output of publications including articles, reviews, letters, notes, editorials, and book reviews of India, Greece, and Belgium declined between 1996-1997 and 1998-1999. All measures indicate that in the USA all subjects of renewable energy received more or less the same priority. The rest of the countries had differentiated high- or low-priority profiles in different subjects. Among the main research subjects of renewable energy only photovoltaic technology (PV) had a fairly homogenous profile for all countries. (Author)

  13. Operation Strategy for a Power Grid Supplied by 100% Renewable Energy at a Cold Region in Japan

    Jorge Morel

    2014-09-01

    Full Text Available This paper presents an operation strategy for a power system supplied from 100% renewable energy generation in Kitami City, a cold region in Japan. The main goal of this work is the complete elimination of the CO2 emissions of the city while keeping the power frequency within prescribed limits. Currently, the main energy related issue in Japan is the reduction of CO2 emissions without depending on nuclear generation. Also, there is a need for the adoption of distributed generation architecture in order to permit local autonomous operation of the system by the local generation of power. As a solution, this paper proposes a strategy to eliminate CO2 emissions that considers digital simulations using past hourly meteorological data and demand for one year. Results shows that Kitami City can be supplied entirely by renewable generation, reducing its CO2 emission to zero while keeping the quality of its power grid frequency within permitted limits.

    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

    In the last quarter of this century, global environmental problem has emerged as a major scientific, political and social issue. Specific Problems include: depletion of ozone layer by chlorofluorocarbons (CFCs), acid rain, destruction of tropical forests and desertification, pollution of the sea and global wanning due to the greenhouse effect by carbon dioxide and others. Among these problems, particular attention of the world has been focused on the global warming because it has direct linkage to energy consumption which our economic development depends on so far. On the other hand, the future program of The Sunshine Project for alternative energy technology R&D, The Moonlight Project for energy conservation technology R&D, and The Global Environmental Technology Program for environmental problem mitigating technology R&D which are Japan`s national projects being promoted by their Agency of Industrial Science and Technology (AIST) in the Ministry of International Trade and Industry have been reexamined in view of recent changes in the situations surrounding new energy technology. In this regard, The New Sunshine Program will be established by integrating these three activities to accelerate R&D in the field of energy and environmental technologies. In the reexamination, additional stress has been laid on the contribution to solving global environmental problem through development of clean renewable energies which constitute a major part of the {open_quotes}New Earth 21{close_quotes}, a comprehensive, long-term and international cooperative program proposed by MITI. The present paper discusses the results of feasibility study on hydrogen energy system leading to the concept of WE-NET following a brief summary on R&D status on solar and wind energy in Japan.

    1994-06-01

    Including renewable energy resources in integrated resource planning (IRP) requires that utility planning models properly consider the relevant attributes of the different renewable resources in addition to conventional supply-side and demand-side options. Otherwise, a utility`s resource plan is unlikely to have an appropriate balance of the various resource options. The current trend toward regulatory set-asides for renewable resources is motivated in part by the perception that the capabilities of current utility planning models are inadequate with regard to renewable resources. Adequate modeling capabilities and utility planning practices are a necessary prerequisite to the long-term penetration of renewable resources into the electric utility industry`s resource mix. This report presents a review of utility planning models conducted for the National Renewable Energy Laboratory (NREL). The review examines the capabilities of utility planning models to address key issues in the choice between renewable resources and other options. The purpose of this review is to provide a basis for identifying high priority areas for advancing the state of the art.

    2015-12-01

    Full Text Available The article considers the main types of wind and solar electric installations, and provides a comparative analysis of the renewable energy potential of the Krasnodar region. Currently, humankind cannot live without electricity. Production and consumption of electricity is constantly increasing and the cost of it is constantly becoming more expensive. The cost of oil production (to get oil out of the ground increases. The cost of electricity is going up because the cost of basic materials such as copper is at an unprecedented high. Such alternatives energy sources such as solar and wind are real solutions to these problems, moreover, the cost of "traditional" energy sources will only increase. To date, the most popular and invest renewable energy sources are the solar energy and the wind. The solar energy in the Krasnodar region is more profitable than wind, despite the fact that the production of solar installations is more expensive. But every year, the price of solar energy is being reduced and soon will be equal to the price of wind energy, and science and technology do not stand still, and considering the abundance of sunlight in the Krasnodar region, the solar installation will pay off much faster

    Only a small fraction of the antibodies in a traditional polyclonal antibody mixture recognize the target of interest, frequently resulting in undesirable polyreactivity. Here, we show that high-quality recombinant polyclonals, in which hundreds of different antibodies are all directed toward a target of interest, can be easily generated in vitro by combining phage and yeast display. We show that, unlike traditional polyclonals, which are limited resources, recombinant polyclonal antibodies can be amplified over one hundred million-fold without losing representation or functionality. Our protocol was tested on 9 different targets to demonstrate how the strategy allows the selective amplification of antibodies directed toward desirable target specific epitopes, such as those found in one protein but not a closely related one, and the elimination of antibodies recognizing common epitopes, without significant loss of diversity. These recombinant renewable polyclonal antibodies are usable in different assays, and can be generated in high throughput. This approach could potentially be used to develop highly specific recombinant renewable antibodies against all human gene products.

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses, can significantly contribute in reducing dependency on fossil fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will contribute to preserving the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions, through a reduction in air pollution and greenhouse gases, by the replacement of conventional fuels with renewable energies.

    Historically the promotion of renewable energy technologies in isolated areas has involved international donors or governments subsidising the initial capital investment. This paper proposes an alternative support mechanism for remote villages based on the generation of renewable electricity. This communication presents an evaluation of the Renewable Energy Premium Tariff (RPT) scheme, a locally adapted variation of the Feed-in Tariff tailored for decentralised grids of developing countries. The RPT scheme stimulates the deployment of renewable energy technologies by paying for renewable electricity generated. A good-quality performance is secured since the support is given based on the electricity produced by renewables, not for the initial capital investment. The mechanism has been designed to provide a cost-effective scheme for the introduction of renewable energy technologies to remote villages, to provide sustainable and affordable electricity to local users, to make renewable energy projects attractive to policy-makers, and concurrently decrease financial risk to attract private sector investment.

    Full Text Available A Markov Modulated Poisson Process (MMPP M(t defined on a Markov chain J(t is a pure jump process where jumps of M(t occur according to a Poisson process with intensity λi whenever the Markov chain J(t is in state i. M(t is called strongly renewal (SR if M(t is a renewal process for an arbitrary initial probability vector of J(t with full support on P={i:λi>0}. M(t is called weakly renewal (WR if there exists an initial probability vector of J(t such that the resulting MMPP is a renewal process. The purpose of this paper is to develop general characterization theorems for the class SR and some sufficiency theorems for the class WR in terms of the first passage times of the bivariate Markov chain [J(t,M(t]. Relevance to the lumpability of J(t is also studied.

    This paper studies the links between non-renewable and intermittent renewable energy sources in the production of electricity. Using U.S. state-level data from 1998 to 2015, we find that the relationship between the price of natural gas and investments in solar and wind capacity is non-linear and can be represented by an inverted U-shape. Hence, for relatively low natural gas prices, the two modes of production are substitutes. After a price threshold is reached, the two ...

    Since the early 1990s, Los Alamos National Laboratory (LANL) has applied electric grid models and simulation software to problems of national significance. This effort continues with a variety of other projects funded by the Department of Energy (DOE), other federal and state agencies and private companies. Critical to the success of these programs is the ability to integrate regional-scale models of the electric grid, to assess the propagation of grid impacts, and to present interactively the effect of potential mitigating actions required to stabilize the grid. All of these capabilities are applied in this study, to accomplish the following goals and objectives: (1) Develop an AC power flow model representing future conditions within New Mexico's electric grid, using commercial tools accepted by the utility industry; (2) Conduct a 'screening' analysis of options for accelerating potential renewable energy development through the addition of a statewide transmission collector system; (3) Estimate total revenue needed, jobs created (temporary and permanent) plus indirect and direct impacts to the state's economy; (4) Evaluate potential cost allocation methodology; and (5) Issue a project report that will provide information for policy direction by state regulators, project developers, and legislators.

    This paper compares thermodynamic performance, through energy and exergy efficiencies, of the some renewable-based (e.g. geothermal) and non-renewable-based hydrogen production processes, namely: (1) steam methane reforming (SMR), (2) hybrid copper- chlorine (Cu-Cl) supplied by geothermal heat and electricity from a geothermal power plant, (3) high temperature steam electrolysis (HTSE) supplied by geothermal heat and electricity from a geothermal power plant. These processes are essentially driven by two different sources such as fossil fuel and geothermal. The results show that energy and exergy efficiencies during hydrogen production range from 65-89% and 63-80% for the SMR. The efficiencies of geothermal-based hydrogen production processes seem to be a bit lower than that of SMR. However, these processes can drastically reduce the GHG emissions compared to non-renewable energy based ones, e.g., SMR process. (orig.)

    The accommodation and curtailment of renewable energy in northeast China have attracted much attention with the rapid growth of wind and solar power generation. Large amount of wind power has been curtailed or abandoned in northeast China due to several reasons, such as, the redundancy of power supplies, inadequate power demands, imperfect power structure with less flexibility and limited cross-regional transmission capacity. In this paper, we use multi-area production simulation to analyse the accommodation of renewable energy in northeast China by 2020. Furthermore, we suggest the measures that could be adopted in generation, grid and load side to reduce curtailment of renewables.

    Full Text Available Energy production based on fossil fuel reserves is largely responsible for carbon emissions, and hence global warming. The planet needs concerted action to reduce fossil fuel usage and to implement carbon mitigation measures. Ocean energy has huge potential, but there are major interdisciplinary problems to be overcome regarding technology, cost reduction, investment, environmental impact, governance, and so forth. This article briefly reviews ocean energy production from offshore wind, tidal stream, ocean current, tidal range, wave, thermal, salinity gradients, and biomass sources. Future areas of research and development are outlined that could make exploitation of the marine renewable energy (MRE seascape a viable proposition; these areas include energy storage, advanced materials, robotics, and informatics. The article concludes with a sustainability perspective on the MRE seascape encompassing ethics, legislation, the regulatory environment, governance and consenting, economic, social, and environmental constraints. A new generation of engineers is needed with the ingenuity and spirit of adventure to meet the global challenge posed by MRE.

    Novel strategies for sustainable replacement of finite fossil fuels are intensely pursued in fundamental research, applied science and industry. In the case of jet fuels used in gas-turbine engine aircrafts, the production and use of synthetic bio-derived kerosenes are advancing rapidly. Microbial biotechnology could potentially also be used to complement the renewable production of jet fuel, as demonstrated by the production of bioethanol and biodiesel for piston engine vehicles. Engineered microbial biosynthesis of medium chain length alkanes, which constitute the major fraction of petroleum-based jet fuels, was recently demonstrated. Although efficiencies currently are far from that needed for commercial application, this discovery has spurred research towards future production platforms using both fermentative and direct photobiological routes.

Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

    Full Text Available ieving the Renewable Energy Target for Jamaica Abstract: The high cost of energy in Jamaica, one of the highest in the Caribbean region, is usually cited as a hindrance to industrial development and efficiency, especially in the manufacturing sector. High energy cost is also considered to be a national energy security issue and the government is taking steps to ensure adequate supply of energy at affordable prices. In the current National Development Plan, the government has set a target for renewable energy sources to supply 20% of the country's energy need by the year 2030. Using a linear programing model of energy planning, we examine how realistically this target could be achieved. Our findings indicate that the 20% renewable energy target is technically achievable with the optimal plan showing a mixture of wind power, hydropower and bagasse power but no solar power. However, when the timeline for investment in new generating capacities that will ensure the attainment of the target is considered, it becomes highly improbable that the target will be met. This study fills the gap that exists in evidence-based analysis of energy policy in Jamaica.

    In many scientific societies, presentation by poster has become a popular alternative to oral delivery for contributed papers at major meetings. This has not been so in the AGU. My purpose in this 'editorial' is to acquaint the AGU membership with some of the advantages of the poster paper as an occasional alternative to the 10-minute talk.The main advantage for the author of a poster paper is the opportunity for interaction with an interested audience for a 3 hour period. Significant feedback from the audience is a bonus that gives the author a better understanding of his own work and how to explain it, both orally and in print. Those of us who have tried poster presentation have found it to be a very positive experience.

    The County of Somerset, New Jersey, through the Somerset County Improvement Authority (SCIA), applied Federal funding through the U.S. Department of Energy to will apply project funds to buy-down the capital costs of equipment associated with the installation of solar photovoltaic (PV) systems at two sites owned by the County. This Renewable Energy Initiative allows the County to take advantage of clean renewable energy, without any adverse debt impacts, and at a price that results in operating budget savings beyond what is presently available in the marketplace. This project addressed the objectives of the Office of Energy Efficiency and Renewable Energy by making the acquisition of renewable energy more affordable for the County, thereby, encouraging other counties and local units to develop similar programs and increase the deployment of solar energy technologies. The two sites that were funded by the DOE grant are part of a much larger, ambitious, and unique renewable energy project, described in the next section.

    The development of the use of renewable energy sources in Germany in 2011 significantly was influenced by the disaster in Fukushima (Japan) and the change of course in the German energy policy. In addition, there is the amendment of the Renewable Energy Law (EEG) in an increasingly controversial area of tension between climate protection, energy utilization, cost minimization and considerations on sustainability. With this in mind, the authors of the contribution under consideration report on developments in Germany in the year 2011 in the field of energy supply and fuel supply from renewable energies. Beside the energy-economic framework conditions for the various possibilities for the use of renewable energies, the current status, developments and prospects are analysed. The contribution gives an outlook on the possible expansion of the supply of renewable energies in 2012.

    The costs of electric power projects utilizing renewable energy technologies are highly sensitive to financing terms. Consequently, as the electricity industry is restructured and new renewables policies are created, it is important for policymakers to consider the impacts of renewables policy design on project financing. This report describes the power plant financing process and provides insights to policymakers on the important nexus between renewables policy design and finance. A cash-flow model is used to estimate the impact of various financing variables on renewable energy costs. Past and current renewable energy policies are then evaluated to demonstrate the influence of policy design on the financing process and on financing costs. The possible impacts of electricity restructuring on power plant financing are discussed and key design issues are identified for three specific renewable energy programs being considered in the restructuring process: (1) surcharge-funded policies; (2) renewables portfolio standards; and (3) green marketing programs. Finally, several policies that are intended to directly reduce financing costs and barriers are analyzed. The authors find that one of the key reasons that renewables policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy incentives. A policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will, in turn, reduce financing risk premiums.

    Over the last decade Germany has boosted renewable energy in power production by means of massive subsidies. The flip side are very high electricity prices which raises concerns that the transition cost towards a renewable energy system will be mainly borne by poor households. In this paper, we combine computable general equilibrium and microsimulation analysis to investigate the cost-effectiveness and incidence of Germany's renewable energy promotion. We find that the regressive effects of renewable energy promotion could be ameliorated by alternative subsidy financing mechanisms which achieve the same level of electricity generation from renewable energy sources.

    The climate is changing, the worlds known fossil energy reserves are limited, and most economies are struggling to get out of a financial crisis. The UNs Intergovernmental Panel on Climate Change calls for new technologies, rapid commercialization, and rapid international diffusion as important tools to mitigate the climate change (IPCC 2007). Nations all over the world have allocated large funds to facilitate the development of renewable energy technologies and markets to secure the future supply of energy and to sustain economic growth (REN21 2009). Use of fossil fuel is the main source of humans contribution to global warming. At the same time, fossil fuel is probably the most important resource for economic development on a global scale (IEA 2009). With this as a backdrop, the objective of this PhD thesis is to investigate how technology-based companies act to commercialize and internationally diffuse technologies that may produce abundant clean, renewable energy. More specifically, I have assessed the emerging offshore renewable energy industries (offshore wind, wave, and tidal energy) as case industries to make the International Entrepreneurship literature more relevant for the current situation. The findings reveal extensive international activities at both the company level and industry level, even in phases in which the firms have yet to commercialize and industries have yet to enter the growth phase. These findings demand significant updates to theoretical models and convey several recommendations to mangers, investors, and policy makers. Managers should be aware of and master the new opportunities/threats identified. For investors, the findings provide implications for their valuation of new ventures. For policy makers, the findings open up a new landscape of political threats and opportunities as the battle to attract promising industries has begun earlier than previously prescribed. Four research questions have resulted in four papers that constitute

    Full Text Available The increasing attention to environmental issues is forcing the implementation of novel energy models based on renewable sources. This is fundamentally changing the configuration of energy management and is introducing new problems that are only partly understood. In particular, renewable energies introduce fluctuations which cause an increased request for conventional energy sources to balance energy requests at short notice. In order to develop an effective usage of low-carbon sources, such fluctuations must be understood and tamed. In this paper we present a microscopic model for the description and for the forecast of short time fluctuations related to renewable sources in order to estimate their effects on the electricity market. To account for the inter-dependencies in the energy market and the physical power dispatch network, we use a statistical mechanics approach to sample stochastic perturbations in the power system and an agent based approach for the prediction of the market players' behavior. Our model is data-driven; it builds on one-day-ahead real market transactions in order to train agents' behaviour and allows us to deduce the market share of different energy sources. We benchmarked our approach on the Italian market, finding a good accordance with real data.

    Full Text Available This paper addresses the challenge of transforming Mediterranean islands into sustainable tourism areas, through the direct (or indirect use of renewable energy projects and technologies. Through demonstration and a discussion of cases studies from studied islands, which takes into account island-specific characteristics and particularities, we assess the compatibility of renewable energy technologies (RETs with sustainable tourism development. Conclusions emerge from this analysis which highlight prerequisites for RET-tourism compatibility; this has potential transferability to other insular territories. Developing an appreciation of the factors that can lead to sustainable tourism in islands through the use of renewable energy is a priority issue for two main reasons. Firstly, because until now scientific literature has only discussed the question of photovoltaics’ integration into tourism buildings, and secondly, because of the relatively high vulnerability to climate change impacts of islands compared to many mainland areas, according to predictions made by the United Nations and the European Union. Whilst international politics deal with the mass reduction of gaseous emissions into the atmosphere, reducing the adverse effects of climate change in the islands has become a significant component of national priorities.

    Full Text Available This paper presents an approach in support of spatial planning for renewable energy at the regional level. It aims to establish an elaborate and informative procedure, as well as integrated quantification and visualization, to support decision making. The proposed approach is composed of a set of sequential steps that include primary energy consumption estimation, renewable energy potential estimation, energy self-sufficiency analysis, and composite map preparation using Geographic Information System (GIS. GIS is used to analyze solar, wind, biomass, geothermal, and hydro-power potential within Fukushima Prefecture, Japan. Potential sites are determined based on geographic, topographic, and land use constraints. Evacuees’ population and forest radiation levels are specifically considered in the context of consequent issues emanating from Fukushima Daiichi nuclear crisis. Energy self-sufficiency analysis has been conducted for years 2020 and 2030. A composite map showing potential sites and their interrelation to the above renewable energy resources has also been presented. These results may support decision making in regional renewable energy planning, by providing information on regional potentials and restrictions to different energy stakeholders. This can help to build an energy developmental vision, which can drive regional energy development towards sustainability. The proposed approach can also be applied to other Japanese municipalities or regions. It provides an example on how to establish local GIS databases through the utilization of various online open GIS resources in Japan.

    In the last two decades, there has been a rich debate about the environmental degradation that results from exposure to solid urban waste. Growing public concern with environmental issues has led to the implementation of various strategic plans for waste management in several developed countries, especially in the European Union. In this paper, the relationships were assessed between economic growth, renewable energy extraction and greenhouse gas (GHG) emissions in the waste sector. The Environmental Kuznets Curve hypothesis was analysed for the member states of the European Union, in the presence of electricity generation, landfill and GHG emissions for the period 1995 to 2012. The results revealed that there is no inverted-U-shaped relationship between income and GHG emissions in European Union countries. The renewable fuel extracted from waste contributes to a reduction in GHG, and although the electricity produced also increases emissions somewhat, they would be far greater if the waste-based generation of renewable energy did not take place. The waste sector needs to strengthen its political, economic, institutional and social communication instruments to meet its aims for mitigating the levels of pollutants generated by European economies. To achieve the objectives of the Horizon 2020 programme, currently in force in the countries of the European Union, it will be necessary to increase the share of renewable energy in the energy mix.

    -related issues (in renewables and climate change, soft governance or governance based on aims and commitments formulated by countries themselves and not by international organizations becomes most efficient; the best results are demonstrated by new agencies dedicated to renewable energy only. According to the authors, although Russia has taken part in all major relevant initiatives, the results of its efforts have been rather poor, except for the creation and implementation of the legal framework for renewable energy. Russia’s efforts have been mostly declarative in nature. The main reason for this poor performance is the low level of renewable energy development in Russia (except for large hydro, underpinned by the prevailing inertial development model of the energy sector and the whole economy. However, the rapid diffusion of renewable energy technologies in global markets may affect Russia’s oil and gas sectors negatively. Therefore, Russia should increase and improve its participation in global renewable energy governance in order to provide national energy and economic security in the long run.
