    Full Text Available La surconsommation de sucres ajoutés et leurs effets putatifs sur diverses pathologies cardiométaboliques continuent de susciter des controverses. Dans les années 1950, le taux élevé de maladies cardiovasculaires (MCV, chez les hommes Américains a conduit à des études sur le rôle des facteurs alimentaires, tels que le cholestérol, les phytostérols, l'excès de calories, les acides aminés, les graisses, les glucides, les vitamines et les minéraux, à influencer le risque de MCV. Dans les années 60, deux éminents physiologistes, plaidant pour des hypothèses causales divergentes de MCV, John Yudkin a identifié les sucres ajoutés comme agent primaire, tandis que Ancel Keys identifiait les graisses totales, les graisses saturées et le cholestérol alimentaire. Cependant, dans les années 80, peu de scientifiques croyaient que les sucres ajoutés jouaient un rôle important dans la maladie coronarienne, et les premiers conseils nutritionnels de 1980 (1980 Dietary Guidelines for americans étaient axés sur la réduction des graisses totales, des graisses saturées et du cholestérol alimentaire pour la prévention des MCV.

Dans cet article, nous proposons d’analyser de manière approfondie ce document pour comprendre la controverse fondatrice qui a justifié les travaux du futur métro à Bruxelles. En faisant parler les archives institutionnelles, nous soutenons que le métro bruxellois peut être considéré comme le résultat d’un compromis entre les deux institutions à l’époque en charge de la mobilité à Bruxelles : le Ministère des Travaux Publics et le Ministère des Communications. Préférant répondre aux normes de capacité et de rapidité déjà présentes dans le monde routier, le transport public a ainsi fait le deuil de la surface et, par là, a purifié le débat des mobilités urbaines en une solution apparemment strictement technique, espace pacifié où protagonistes d’un champ désormais commun peuvent s’entendre et s’allier.In 1963 the Belgian Ministry of Communications published a document entitled “Promotion des Transports en commun dans les grandes agglomérations”, real plea for the defence of public transport on the scale of five Belgian cities. In this article, we propose to analyze this document deeply, to help the understanding of the founding controversy which justified the works of future metro in Brussels. By studying institutional archives, we maintain that the Brussels metro may be considered as the result of a compromise between the two institutions dealing with mobility at that time in Brussels: the Ministry of Civil Engineering and the Ministry of Communications. Through responding to capacity and speed standards already present in the field of road transport, public transport gave up the surface and turned the debate on urban mobility into an apparently

Influencé par ses pairs, l’Eva Prima Pandora et le Livre de Pourtraicture de Jean Cousin font largement référence aux proportions de Vitruve par l’intermédiaire d’Albrecht Dürer et à l’anatomie pour justifier la primauté de la peinture sur la sculpture en prenant comme point de départ les commentaires de Benedetto Varchi. Dans ces deux œuvres, Jean Cousin insère un double débat dans lequel il démontre que l’autorité d’André Vésale sert justement à justifier la primauté de la peinture sur la sculpture. Ce débat est repris un siècle plus tard par André Félibien au sujet des œuvres de Poussin dans lesquelles l’artiste, connu pour avoir aussi pratiqué l’anatomie, continue à faire référence à André Vésale. En un siècle, on peut constater combien les artistes doivent à la Fabrica de Vésale dont le propos et les planches servent à nourrir les débats qui entourent les arts de la peinture et de la sculpture.

    France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

    Although the vast majority of renewable energies projects are established by commercial developers, some of them are financed by ''ordinary citizens'' pooling together through different schemes. This is particularly frequent in Denmark and Germany, possibly a key reason for the continuous and so successful growth of various renewable energies sources in these countries. This guideline aims to define the term of local investment and provides examples of development and recommendations. (A.L.B.)

    These proceedings present some European testimonies about the advantage of local investment, illustrated with concrete cases taken in Germany, Denmark and Switzerland. They demonstrate that local investment in renewable energy sources is a reality and that this practice has indisputably contributed to their significant development in some countries of the European Union. The sustain of foreign banks to the financing of renewable energy sources is at the evidence an example to follow up in countries like France, Greece or Spain. Important efforts have to be made to simplify and encourage the implementation of projects, in particular from the administrative point of view. Beyond the financial aspects, the colloquium has shown that these practices of citizenship involvement represent an important factor of social adaptation and acceptation. The projects, gathering local actors but also the overall citizens through common investment funds, ensure a better territorial anchoring and a sustain to local and sustainable development. This document has been published with the support of the European Commission and ADEME (French Agency for Environment and Energy Management). (J.S.)

    Renewable energies do not produce any additional greenhouse gas emissions and do not leed to the production of dangerous wastes. The facilities used for their valorization are easily dismantled at the end of their life, and they offer many advantages in terms of employment, local economy, decentralization and national development. Their main drawbacks concern the required land surfaces and the intermittency of their availability. This paper analyzes the feasibility and the medium- and long-term perspectives of development of renewable energies in France and in Europe: costs and conditions (decentralized production, public acceptability, competitiveness, investments, operating costs, international cooperation).

    Full Text Available The opening of Great Exhibition of 1851 coincided with the start of a long debate on the law of patents. The question was whether patents were an encouragement to economic development or a hindrance. For The Economist which had been founded a few years earlier in the wake of the debate on the Corn Laws, the straightforward answer was that they were a hindrance and should be abolished. This article examines the arguments used by The Economist and shows that its analysis technological progress in the Victorian industry foreshadowed some of today’s concerns.

    Energy Technology Data Exchange (ETDEWEB)

    Fallot, A.

    2003-07-01

    In France, the persistence of biofuels at an experimental or pre-industrial stage, hangs on measures that were taken on the account of environmental policy in the energy sector. Our recent and thorough case study has resulted in the statement that biofuels do not offer the prospects for enough profitability to any economic agent - neither biomass providers nor energeticists - that would justify the investments necessary to reach large scale production. A real biofuel 'file' is not viable in a context where fossil energies dominate, nor in a context where the complete taking into account of environmental variables would have defeated the ''technological lock-in'' that nowadays excludes no-carbon technologies. We look for an explanation of the continuing public support to biofuels in the present peculiar context, where new measures of environmental policy are being decided in the energy sector without any agreement on the importance of environmental and other long term issues. For that matter, we propose a simple option value model, where both issues of irreversibility and uncertainty are tackled. (author)

    A solar tower is a renewable energy plant, designed to channel the air warmed by the sun, in order to produce electric power by the use of turbines. It is composed of a giant greenhouse with a chimney in its center. The capacity of this system is proportional to the chimney high. That is the reason why french engineers proposed to use the hillsides to build chimneys of many kilometers high. The project and some technical informations are provided in this paper. (A.L.B.)

    Full Text Available Une controverse, dont les origines remontent à l’Antiquité, secoue régulièrement les sciences du langage, et a marqué certains moments importants de l’histoire de la linguistique française : elle concerne le caractère dérivé ou autonome de l’écriture par rapport à l’expression orale. Dans ce débat interviennent des considérations linguistiques, mais aussi historiques, esthétiques et philosophiques. On examinera ici les thèses des autonomistes (parmi lesquels on distinguera les autonomistes radicaux et les autonomistes relatifs et des glossographistes (également répartis entre radicaux et relatifs pour faire apparaitre les conséquences ultimes, et souvent aporétiques, de leurs positions. Dans un exposé dont la spécificité sera qu’il mobilise autant les acquis de la sémiotique visuelle et de la sémiotique de l’espace que ceux de la linguistique, nous testerons l’intérêt et les limites de ces positions, pour énoncer une série de conditions auxquelles un système sémiotique doit obéir pour pouvoir être appelé écriture, et finalement aboutir à une définition de l’écriture échappant aux critiques.

    Full Text Available Le personnage de Salāh al-din Yūsuf, officier kurde au service de Nūr al-dïn devenu maître de l'Égypte puis de Damas et enfin d'Alep, et fondateur de l'empire ayyoubide, a été fort controversé de son vivant avant de devenir pour la postérité « le plus pur des héros de l'Islam ». Pour ses adversaires, les Francs d'Orient, il a de bonne heure suscité leur curiosité, et ceux-ci ont recueilli des informations qu'ils ont utilisées, dès avant 1187, dans un Carmen de Saladino où l'aventurier qu'il était à leurs yeux est présenté sous des traits peu recommandables. Son manque de fidélité envers ses maîtres est particulièrement souligné. Les coups très durs qu'il a portés aux Francs ont été assortis de traits de cruauté ; mais ce sont les manifestations d'un esprit chevaleresque, dont les valeurs étaient communes aux deux camps, qui ont vite retenu l'attention. Le trouvère Ambroise le regarde encore comme un ennemi fort capable de perfidie ; mais le traducteur de Guillaume de Tyr adoucit les remarques du livre qu'il mettait en français pour le rendre plus sympathique. Les textes de caractère épique où il apparaît dans la première moitié du XIIIe siècle (Estoires d'Outremer, Ordene de Chevalerie accentuent ce caractère. Mais c'est dans le second cycle de la croisade qu'on le pare des qualités les plus éminentes qu'on attend d'un chevalier. On lui prête des origines chrétiennes (La fille du comte de Ponthieu et on lui attribue le beau rôle, en insistant sur sa générosité et sur sa bravoure, en lui faisant arbitrer des controverses religieuses, en lui prêtant enfin une aspiration à une mort chrétienne, qui sont bien loin du portrait que faisaient de lui les Francs de la fin du XIIe siècle.

    Full Text Available La perspective critique élaborée par Henri Lefebvre demeure pertinente pour penser les rapports sociaux à l’espace, y inclus ceux qu’on observe dans les métropoles contemporaines en Amérique du Nord. En examinant la controverse autour de la forme urbaine telle que celle-ci a été remise à l’ordre du jour dans les années 1990 à la faveur du discours néorégionaliste, ce texte pose la question de l’avenir des métropoles et du modèle de ville dans lequel on souhaite vivre. La thèse défendue peut se résumer comme suit : afin de faire échec à la position libérale qui accorde la préséance aux facteurs économiques et aux forces du marché, les acteurs sociaux doivent porter le débat autour de la forme urbaine sur le terrain politique. À cette fin, l’urgence demeure de mobiliser la communauté politique.Henri Lefebvre’s critical approach remains appropriate for thinking about social relationships to space, including those we can now assess in North American metropolis. Through analyzing the controversy about the urban form as it has been highlighted again during the nineties and favored by the new regionalist discourse, this paper poses the question of the future of metropolis and the posterity of the urban model in which one wishes to live. Its thesis could be summarized like this : in order to make fail the liberal position which privileges to economical factors and market forces, social actors have to orientate the debate about the urban form towards the political field. In such a perspective, the emergency remains to mobilize the polity.

  9. Les barrages alpins

    Full Text Available Les barrages-réservoirs de montagne ont été réalisés initialement dans les Alpes pour répondre à la demande d’énergie en période hivernale. Une certaine diversification des usages de l’eau s’est ensuite progressivement développée, en relation avec le développement touristique des collectivités locales. Aujourd’hui, la participation des ouvrages d’Électricité De France à la production de neige de culture représente une nouvelle étape. Dans les régions où les aménagements hydroélectriques sont nombreux, les besoins en eau pour la production de neige peuvent être résolus par prélèvements à partir des adductions EDF. Les gestionnaires de stations échappent ainsi aux inconvénients liés à la construction et à la gestion des « retenues collinaires ». Cette évolution, qui concerne déjà quelques régions alpines comme la haute Maurienne ou le Beaufortin, apparaît comme une forme renouvelée d’intégration territoriale de la ressource en eau.Mountain reservoirs were initially built in the Alps to meet energy needs in the winter. A certain diversification in the uses of water then gradually developed, related to tourism development in the local communities. Today, the use of facilities belonging to EDF (French Electricity Authority to provide water for winter resorts to make artificial snow represents a new phase. By taking water from EDF resources to supply snow-making equipment, resort managers are thus able to avoid the problems related to the construction and management of small headwater dams. This new orientation in the use of mountain water resources already affects a number of alpine regions such as the Upper Maurienne valley and Beaufortain massif and represents a renewed form of the territorial integration of water resources.

    A reduction in energy consumption by the energy intensive sectors will be rewarded by a tax credit. The advantages of renewable sources of energy in terms of reducing emissions of carbon dioxide are extolled. The Government will reward the use of renewables through exemption from the Climate Change Levy. Many major companies are now committed to renewables and Shell predict that 50% of world energy will come from renewables by 2050. World-wide there is now 10,000 MW of installed wind power and the annual rate of growth is more than 20%. Other renewables such as biomass, energy from waste, solar power, hydropower, wind power and tidal power are discussed.

Over 17,000 items now feature in the national database Palissy, on moveable objects. The first scientific vocabulary, published by the Inventory services in 1969, was devoted to tapestry and, over the last twenty years, other vocabularies have dealt with sculpture, domestic civil furniture and stained glass.

  16. License renewal

    International Nuclear Information System (INIS)

    Newberry, S.

    1993-01-01

    This article gives an overview of the process of license renewal for nuclear power plants. It explains what is meant by license renewal, the significance of license renewal, and goes over key elements involved in the process of license renewal. Those key elements are NRC requirements embodied in 10 CFR Part 54 (Reactor Safety) and 10 CFR Part 51 (Environmental Issues). In addition Industry Reports must be developed and reviewed. License renewal is essentially the process of applying for a 20 year extension to the original 40 year operating license granted for the plant. This is a very long term process, which involves a lot of preparation, and compliance with regulatory rules and guidelines. In general it is a process which is expected to begin when plants reach an operating lifetime of 20 years. It has provisions for allowing the public to become involved in the review process

    Renewable energy sources have a small environmental impact and can be easily integrated within existing structures. Moreover, the use of renewable energy sources can contribute to achieve a zero emission of carbon dioxide by 2100, provided an efficient environmental policy during the next 40 years. This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

    RÉSUMÉ Même si, au Canada, les mineurs n’ont pas le droit de jouer à des jeux de hasard légalisés, les adolescents participent souvent à des jeux de hasard soit légalisés (produits de loterie, casino, terminaux de jeux vidéo), soit autonomes (jeux de cartes, paris sportifs, dés) à la maison et en milieu scolaire. Chez les adultes, le taux de prévalence de dépendance aux jeux de hasard au cours de la vie se situe entre 1 % et 2 %. D’après les données existantes, la prévalence chez les adolescents serait de deux à quatre fois plus élevée. On ne sait pas grand-chose des facteurs de risque d’apparition et de perpétuation d’une dépendance pathologique aux jeux de hasard. Le présent document de principes vise à informer les pédiatres, les médecins de famille et les autres professionnels de la santé des connaissances émergentes sur les jeux de hasard pendant l’enfance et l’adolescence et du risque de conséquences graves qui s’y rattachent. On y exhorte également les gouvernements fédéral, provinciaux et territoriaux à inclure cette question dans leur programme et à tenir compte des facteurs sociopolitiques associés aux jeux de hasard.

    Depuis les années 1990, les conditions de travail se sont peu à peu imposées dans le débat social. Néanmoins, la situation reste critique. Les risques traditionnels n'ont pas disparu : les manutentions lourdes, l'exposition professionnelle aux cancérogènes, au bruit ou aux vibrations demeurent répandues... De plus, certaines " améliorations " n'ont fait que déplacer et dissimuler les problèmes, telle l'externalisation des risques grâce à la sous-traitance. Dans le même temps, les transformations du travail et des modalités de gestion de la main-d'œuvre ont fragilisé les collectifs et accru l'isolement des salariés, conduisant à une montée visible de la souffrance psychique.

L’analyse des différentes séquences du processus polémique vise à identifier les types de manipulation auxquels ces documents ont été soumis depuis leur collecte jusqu’à leur usage polémique et à étudier leurs modes d’articulation avec les logiques historiographiques, politiques et économiques qui en ont sous-tendu le développement. L’examen des dispositifs éditoriaux adoptés par les protagonistes de la polémique mettra en lumière leur rôle dans le déroulement de cette dernière et les effets produits par la matérialité même de ces dispositifs.The subject of this article is the 1980-2000 controversy between Adel Ismail, a Lebanese historian and diplomat who has published a vast collection of French diplomatic documents relating to the modern history of Lebanon, and Antoine Hokayem, an academic historian behind a virulent critique of these publications, himself also the publisher of archive collections. The different stages of the controversy are analysed with the aim of identifying the types of manipulations to which these documents were subjected, from the time they were collected until they were used for polemical purposes, and to study the ways in which they connect with the historiographical, political and economic rationales that underlay their development. An examination of the editorial apparatuses adopted by the controversy’s protagonists will shed light on their role in its development and the effects produced by the very materiality of these apparatuses.

    Full Text Available Cet article propose une étude de quelques livres d’Église tenus par des communautés dissidentes baptistes dans la seconde moitié du xviie siècle. Ces livres ont été souvent négligés par les historiens étant donnée la nature lacunaire des informations qu’ils contiennent et leur diversité générique. Après un survol de la littérature de controverse et des nombreuses satires à l’encontre des dissidentes, nous montrons comment cette littérature peut être nuancée grâce aux informations contenues dans les livres d’Église manuscrits. Certains historiens ont développé une vision optimiste des multiples opportunités offertes aux dissidentes dans les assemblées séparatistes. Les livres d’Église présentent des preuves appelant à une révision de cette position. À travers des analyses du rôle des femmes et des rares cas où elles étaient autorisées à s’exprimer devant les assemblées, se révèlent une extrême résistance et un fort conservatisme à l’égard de la parole féminine de la part des pasteurs et des anciens. Même au sein des communautés dissidentes qui pourtant réservaient un accueil favorable aux femmes, ces dernières ne parvenaient pas toujours à braver les interdits bibliques concernant la prise de parole dans l’Église.  This article examines some early Baptist Church Books from the second half of the seventeenth century. They have been generally neglected by historians because the records they contain are often imperfect, and the nature of the information varies so much from one book to the next. After a general presentation of the pamphlet and satirical literature published against dissenting women, I show how this literature may be read in the light of the manuscript Church Books. In recent years, other kinds of evidence have encouraged historians towards a more optimistic view of women’s opportunities in the Baptist Churches. The Church Books present a much more sobering picture

  20. Renewing governance.

    Science.gov (United States)

    Loos, Gregory P

    2003-01-01

    Globalization's profound influence on social and political institutions need not be negative. Critics of globalization have often referred to the "Impossible Trinity" because decision-making must 1. respect national sovereignty, 2. develop and implement firm regulation, and 3. allow capital markets to be as free as possible. To many, such goals are mutually exclusive because history conditions us to view policy-making and governance in traditional molds. Thus, transnational governance merely appears impossible because current forms of governance were not designed to provide it. The world needs new tools for governing, and its citizens must seize the opportunity to help develop them. The rise of a global society requires a greater level of generality and inclusion than is found in most policy bodies today. Politicians need to re-examine key assumptions about government. States must develop ways to discharge their regulatory responsibilities across borders and collaborate with neighboring jurisdictions, multilateral bodies, and business. Concepts such as multilateralism and tripartism show great promise. Governments must engage civil society in the spirit of shared responsibility and democratic decision-making. Such changes will result in a renewal of the state's purpose and better use of international resources and expertise in governance.

Dans la controverse engagée sur l’opportunité d’inoculer la variole, la position de D’Alembert constitue un cas exemplaire de scepticisme portant sur l’application des mathématiques, et en l’occurrence du calcul des probabilités, à des décisions relatives à la vie humaine. D’Alembert, en effet, conteste aux mathématiques sociales le pouvoir de rendre compte de phénomènes humains en y cherchant des régularités et des formalisations sans dissocier les dimensions mathématiques et probabilistes des dimensions philosophiques et éthiques. En suivant le débat qui, au milieu du xviiie siècle, se déroule entre le mathématicien français et son homologue suisse Daniel Bernoulli, on assiste à l’un des épisodes de la lente gestation des notions de prise de risque, de décision et de rationalité.The necessity of a calculation aiming to evaluate a risk can be revoked in doubt when the question is to make a decision in a situation of uncertainty, all the more when the question is about life or death.

D’Alembert, indeed, disputes in the social mathematics the power to describe human phenomena by looking for regularities and for formalizations without separating the mathematical and probability dimensions of the philosophic and ethical ones.

Out of the {beta} solid solution phase appears an eutectoid decomposition of {beta} to ({alpha} + {gamma}) or the formation of a martensitic phase {alpha}''. The {gamma} solid solution shows a decomposition of {gamma} to ({alpha} + {gamma}) or ({alpha} + {gamma}'), or a formation of martensitic phases a' or a'{sub b}. The U-Mo equilibrium diagram is discussed, particularly in low concentrations zones.

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.

    Understanding the impact of wind turbine wake dynamics on downstream turbines is particularly important for the design of efficient wind farms. Due to their tractable computational cost, hybrid RANS/LES models are an attractive framework for simulating separation flows such as the wake dynamics behind a wind turbine. High-order numerical methods can be computationally efficient and provide increased accuracy in simulating complex flows. In the context of LES, high-order numerical methods have shown some success in predictions of turbulent flows. However, the specifics of hybrid RANS-LES models, including the transition region between both modeling frameworks, pose unique challenges for high-order numerical methods. In this work, we study the effect of increasing the order of accuracy of the numerical scheme in simulations of canonical turbulent flows using RANS, LES, and hybrid RANS-LES models. We describe the interactions between filtering, model transition, and order of accuracy and their effect on turbulence quantities such as kinetic energy spectra, boundary layer evolution, and dissipation rate.

    Nous ne doutons pas de l'existence du temps, qui demeure pourtant un objet introuvable. Nous voyons, entendons, goûtons, touchons dans le temps, mais non le temps lui-même. Il concerne toute chose, contraint tout, mais de quelle façon ? Est-il apparu en même temps que l'univers ou l'a t-il précédé ? Est-il dans le monde ou le contient-il ? S'écoule-t-il en sens unique ? Serait-ce la mort qui nous obligerait à penser le temps ? Au XXe siècle, la physique a bouleversé notre conception du temps et en vient à effleurer des questions jusque la façon dont l'homme choisit de vivre et de se vivre. Quelles sont les convergences et les différence entre le temps physique et le temps sensible, existentiel ? Pour éclairer les paradoxes, répondre aux questions, Etienne Klein puise, en contrepoint de la physique, dans la philosophie, la psychologie, la littérature, ma poésie... et le sport.

    A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

  11. Nuclear plant license renewal

    International Nuclear Information System (INIS)

    Gazda, P.A.; Bhatt, P.C.

    1991-01-01

    During the next 10 years, nuclear plant license renewal is expected to become a significant issue. Recent Electric Power Research Institute (EPRI) studies have shown license renewal to be technically and economically feasible. Filing an application for license renewal with the Nuclear Regulatory Commission (NRC) entails verifying that the systems, structures, and components essential for safety will continue to perform their safety functions throughout the license renewal period. This paper discusses the current proposed requirements for this verification and the current industry knowledge regarding age-related degradation of structures. Elements of a license renewal program incorporating NRC requirements and industry knowledge including a schedule are presented. Degradation mechanisms for structural components, their significance to nuclear plant structures, and industry-suggested age-related degradation management options are also reviewed

    1991-01-01

    In order to provide for the continuity of the current generation of nuclear power plant operating licenses and at the same time ensure the health and safety of the public, and the quality of the environment, the US Nuclear Regulatory Commission (NRC) established a goal of developing and issuing regulations and regulatory guidance for license renewal in the early 1990s. This paper will discuss some of those activities underway to achieve this goal. More specifically, this paper will discuss the Commission's regulatory philosophy for license renewal and the two major license renewal rule makings currently underway. The first is the development of a new Part 54 to address procedural and technical requirements for license renewal; the second is a revision to existing Part 51 to exclude environmental issues and impacts from consideration during the license renewal process.

    The European directive 2001/77/CE relative to the promotion of the electric power produced from renewable energy sources and devoted to the domestic power market was enforced on September 27, 2001. It fixes indicative goals for each country and aims at increasing from 14% to 22% the share of electric power of renewable origin in the European power consumption. For France, the goal is to change from 15% in 1997 to 21% by 2010. The directive foresees that each member state makes a presentation of its annual objectives of power consumption of renewable origin and of the measures implemented or foreseen to reach these objectives in October 2002. The transcription of the directive must be achieved by October 2003. This report presents the French indicative goals elaborated in the framework of a power consumption and power production investment planing made at the 2010 vista. These goals are ambitious and require the rational exploitation of all French renewable resources. France must increase its hydroelectric power resources and develop new sources, in particular the wind power and biomass ones. The legal and regulatory measures that have been, or that will be, implemented, should allow to increase the power production of renewable origin with a sustained rate. In parallel, actions of power demand mastery are necessary to ensure a mastered evolution of the overall power demand. (J.S.)

    Wager, J.S.

    1994-01-01

    Over the past three years, the Union of Concerned Scientists (UCS) has evaluated the potential for using renewable energy for electricity in the Midwest, and has been carrying out a multifaceted effort to expand the use of renewables in the region. The UCS study presents a strategy for developing renewable-electric technologies and resources in 12 midwestern states. UCS analysts used a geographic information system (GIS) to create data-bases of renewable resources, land uses, vegetation cover, terrain elevation and locations of utility transmission lines, and to analyze and present information on a .6 mi x .6 mi (1 km x 1 km) grid scale. In addition, UCS developed a model to calculate the net employment impact of renewable versus conventional electricity technologies on a state-by-state basis. In evaluating the costs and benefits of renewable energy sources, UCS analysts explored a cost assessment that accounted for the impact of pollution from fossil fuels on energy resource cost. Researchers also considered the risks associated with fuel-price volatility, environmental regulation, construction lead times and other uncertainties. Finally, UCS researchers suggested steps to remove the institutional, regulatory and legislative barriers that inhibit renewable energy development, and proposed policies to expand the use of the region's renewable resources. The UCS analysis showed that wind is currently the least expensive renewable resource. UCS also found numerous opportunities to expand biomass-electric generation in the near term, such as converting small coal-fired power plants to wood fuel, making greater use of logging residues and co-firing a small percentage of biomass with fossil fuel at large power plants

He also explains how ecologists (notably the ADEME) manipulate figures to make believe that these energies could be an answer to the needs of France, of Europe and of humanity. In a first chapter, he criticises the influence of a so-called green ideology on the design of energy transition. In the second one, he denounces twelve tales about energy transition. In the next chapters, he denounces the sham of renewable energies, and finally tells some unfortunate renewable experiments

  2. Renewable energy in Taiwan

    International Nuclear Information System (INIS)

    Chen, Falin; Lu, Shyi-Min; Wang, Eric; Tseng, Kuo-Tung

    2010-01-01

    With limited indigenous conventional energy resources, Taiwan imports over 99% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Taiwanese government. A medium subtropical island surrounded by the Pacific Ocean, Taiwan has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating exceptionally cheap electricity, renewable energy has not yet fully developed in Taiwan, resulting from a lack of market competition. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Taiwanese government, focused on the development of various renewables. This study reviews the achievements, polices and future plans in this area. (author)

    1998-01-01

    The paper describes the Australian Cooperative Research Centre for Renewable Energy and Related Greenhouse Gas Abatement Technologies (ACRE), its technologies, commercial relationships and markets. The relevance of ACRE to developing country communities which lack reliable, adequate power supplies, is discussed. The opportunities for mutual collaboration between Australia and the developing countries in the application of renewable energy have never been stronger. Renewable energy promises real advantages to those who deploy it wisely, as well as significant job creation. Education at all level together with operational training, public awareness of what is possible and increased system reliability, are also vital ingredients for acceptance of these new technologies. They underpin successful commercialisation. The author concludes with the hope for a united international cooperative approach to the development of the renewable energy industry. (author)

    Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

  12. License renewal process

    International Nuclear Information System (INIS)

    Fable, D.; Prah, M.; Vrankic, K.; Lebegner, J.

    2004-01-01

    The purpose of this paper is to provide information about license renewal process, as defined by Nuclear Regulatory Commission (NRC). The Atomic Energy Act and NRC regulations limit commercial power reactor licenses to an initial 40 years but also permit such licenses to be renewed. This original 40-year term for reactor licenses was based on economic and antitrust considerations not on limitations of nuclear technology. Due to this selected time period; however, some structures and components may have been engineered on the basis of an expected 40-year service life. The NRC has established a timely license renewal process and clear requirements codified in 10 CFR Part 51 and 10 CFR Part 54, that are needed to assure safe plant operation for extended plant life. The timely renewal of licenses for an additional 20 years, where appropriate to renew them, may be important to ensuring an adequate energy supply during the first half of the 21st Century. License renewal rests on the determination that currently operating plants continue to maintain adequate levels of safety, and over the plant's life, this level has been enhanced through maintenance of the licensing bases, with appropriate adjustments to address new information from industry operating experience. Additionally, NRC activities have provided ongoing assurance that the licensing bases will continue to provide an acceptable level of safety. This paper provides additional discussion of license renewal costs, as one of key elements in evaluation of license renewal justifiability. Including structure of costs, approximately value and two different approaches, conservative and typical. Current status and position of Nuclear Power Plant Krsko, related to license renewal process, will be briefly presented in this paper. NPP Krsko is designed based on NRC Regulations, so requirements from 10 CFR 51, and 10 CFR 54, are applicable to NPP Krsko, as well. Finally, this paper will give an overview of current status of

    Deshaies, M.

    2009-01-01

    Europe's increasing demand for energy and its environmental preoccupations are creating a favourable environment for the development of renewable energy sources. This article stated that although many European countries have adopted voluntary policies since the 1990s to increase the use of renewable energy sources, they have not been developed in an equal or consistent manner. A table was included to show the consumption of renewable energies by country; the percentage of renewable energies in 1995 as compared to 2006; and the consumption of primary energy resources. Combined, Germany, Spain and Denmark produce 75 per cent of wind energy in Europe, while 75 per cent of Europe's hydroelectricity is produced in Norway, Sweden, France, Italy, Austria and Switzerland. Germany has also made significant contributions in developing biomass energy. The article emphasized that the development of renewable energy sources is limited by the fact that it cannot keep up with growing energy demands. In addition, renewable energies cannot yet replace all fossil fuel consumption in Europe because of the variation in development from one country to another. 1 ref., 2 tabs., 4 figs.

    Full Text Available China is the most densely populated country in the world with high rate of economic growth resulting in higher demand for energy resources and in strive to guarantee stable supply of these resources. Chinese annual GDP growth in 2012 and 2013 was down to 7.7% comparing to 10% in 2000-2011 [7]. In 2012 and 2013 economic growth stumbled because of slowdown in manufacturing and exports, taking into account that Chinese government was eager to cut inflation and excessive investments in some segments of the market. Speaking about energy sector Chinese government is aimed at promotion of market-based pricing systems, activities for advanced energy efficiency and higher competition between energy companies, and increased investment in renewable energy resources. Considering renewables as one of many ways to diversify energy supplies, lower dependence on coal and improve environmental situation Chinese government actively supports and develops programs aimed at support of renewable energy industry in China. Chinese economic development is tightly attached to five-year plans. It seems important to mention the fact that main energy goals for current 12-th "five-year plan" are to achieve 15% renewables consumption and CO2 sequestration up to 40-45% by2020 in order to lower dependency on coal and improve environmental situation. As a result of Chinese state policy to develop renewables China achieved certain results in wind energy, helioenergetics, hydroenergetics and energy from waste recycling.

  8. Renewable energy handbook

    1976-01-01

    The potential for renewable energy use in Canada is examined. It is pointed out that Canada can choose to begin to diversify its energy supply now, moving rapidly and smoothly towards an efficient energy society based on renewable energy sources; or, it can continue on its present course and face the possibility of being forced by necessity to make a later transition to renewable sources, probably with a great deal of economic and political disruption. The handbook begins with a discussion on major issues and options available. This second section deals with the technology, applications, and costs of direct solar energy utilization, solar thermal electricity generation, photovoltaic conversion, wind energy, biomass energy, tidal power, wave energy, ocean thermal energy, geothermal energy, heat pumps, and energy storage. Section three discusses how renewable energy might realistically supply Canada's energy requirements within a reasonable period of time. Some issues on how government, industry, and the individual may become involved to make this happen are suggested. A list of resource people and renewable energy businesses is provided in the last section. A recommended reading list and bibliography complete the handbook. (MCW)

  9. Art : accessible, renewable technology

    This paper focuses on the role of non-governmental organization (NGO) citizen groups in Ontario in the use and production of electricity. NGOs have the potential to act both directly on their own accord, and indirectly by pressuring government and others. Current demand for electricity is divided between industrial, commercial and residential users. Citizens have an important role to play in reducing energy demand. On the supply side, there is a revival of interest in renewable energy based on wind, photovoltaic and local-hydro technologies as a result of the escalating environmental and economic costs of coal and nuclear generation. However, citizen groups have greater interest and enthusiasm than technical expertise, creating a mismatch between technological solutions and human need or use of them. This paper discusses how this mismatch applies to renewable-energy technologies, many of which are not especially user-friendly, or accessible. While alternative technologies are increasingly welcomed by government, industry is developing a large and growing array of technological devices. In between this is the citizen, who, despite keen interest, can be overwhelmed by the complexity of the situation. This paper links the theoretical perspective to the real world with a discussion of the dynamics between people and renewable energy in citizen groups and makes particular reference to one group, Citizens for Renewable Energy, that has been making renewable energy technology more accessible to its members for over a decade

  10. Subsidies for renewable energy?

    Skytte, K.; Grenaa Jensen, S.; Morthorst, P.E.; Olsen, O.J.

    2004-01-01

    Ambitious Danish and European energy and environment objectives make a point of using renewable energy sources in the electricity supply. Denmark has been leading country in successful development and commercialization of wind turbines and is as yet one of the leading manufacturers of the world. Danish governments have successfully invested a lot in this development. Other countries have spent more money without achieving a similar success. The questions are why things have gone so well in Denmark and if the Danish success can be repeated for other renewable energy technologies. The starting point of this book is that a political decision on subsidizing the developmental process of a specific technology not in itself guarantees that the technology will turn out reliable and efficient enough to compete successfully in a liberalized electricity market. An understanding of this development is necessary in order to affect a technological development. This book goes through the development of different renewable energy technologies and two theories used for discussing the technological development: experience curves and innovation theory. Based on the discussions and a description of causal relations, an analytical model for different phases of renewable energy technologies' developmental progress and technological life cycle is made. The model is used for evaluating the subsidies for chosen renewable technologies in Denmark. With wind energy as example an analysis of what went well or badly, what might be done and which actions might be efficient is made. (BA)

    In almost all geothermal projects worldwide, the rate of extraction of heat energy exceeds the pre-exploitation rate of heat flow from depth. For example, current production of geothermal heat from the Wairakei-Tauhara system exceeds the natural recharge of heat by a factor of 4.75. Thus, the current rate of heat extraction from Wairakei-Tauhara is not sustainable on a continuous basis, and the same statement applies to most other geothermal projects. Nevertheless, geothermal energy resources are renewable in the long-term because they would fully recover to their pre-exploitation state after an extended shut-down period. The present paper considers the general issue of the renewability of geothermal resources and uses computer modeling to investigate the renewability of the Wairakei-Tauhara system. In particular, modeling is used to simulate the recovery of Wairakei-Tauhara after it is shut down in 2053 after a hundred years of production. (author)

    The use of renewable energy is tightly connected to solving social problems in Estonia by creating more new jobs. It is essential that Estonia should increase the use of biofuels. One of the biofuels, firewood, has been used already for centuries. For wider use of renewable energy in Estonia, it is not enough to rely only on enterprices. Rather, before any serious progress can take place, the state should create the appropriate legal environment. Due to its many social and environmental aspects, renewable energy is more important to the state than a sole enterprice. Unfortunately, Estonian government has been delaying its duties. Estonia has two resources that should be taken advantage of, fertile spare land and people still used to the country life. The country people would get work by growing different energy crops on the spare land. (author)

    The paper examines some of the factors which will influence the future mix of energy from fossil fuels and renewable sources in Australia. Aspects covered include: the present energy situation; impact of environmental issues; potential for renewable energy; motivators for change; and research and development. It is concluded that the future for fossil fuels and renewable energy is dependent on a number of complex factors, many of which are currently unknown. The key factor is economic viability and that will be influenced by a range of factors such as policies of the Australian and overseas governments in relation to pollution and environment protection (reflected in the cost of meeting such requirements), exploration and production costs (also influenced by government policies), availability of supply, rate of technological development and the size of export markets. 8 refs., 2 figs., 1 tab.

Qu’ils soient en situation régulière ou non, des migrants non arabes dits « temporaires » ou « en transit », mais dont certains sont là depuis une dizaine d’années, ont fait leur entrée sur le marché du travail et tentent de s’inscrire, pour nombre d’entre eux, dans un « milieu » aux identités multiples et conflictuelles dans des quartiers périphériques où il est plus facile de trouver à se loger. En s’appuyant sur des enquêtes de terrain menées dans la banlieue de Bourj-Hammoud à l’est de Beyrouth et dans les quartiers sud de Jnah et de Ouzaï, les auteures décrivent des situations migratoires qui sans être généralisables n’en sont pas moins exemplaires de la place de cette main-d’œuvre immigrée.Since the end of the war, in 1990, unqualified, mostly feminine, workers have been massively entering Lebanon. Whether they have regular registration or not, non-Arab, so-called ‘temporary’, or ‘transit’ migrants have entered the labour market, but some of them have been there for about ten years. Many try to join the mixed, full of conflicts environment of peripheral districts, in which it is easier to find housing. Using fieldwork they have been conducting in the Borj-Hamoud suburb, in the east of Beirut, and Jnah and Ouzaï, in the south, the authors describe migratory situations which, although they cannot be applied generally, are nevertheless a good example of the place held by these immigrant

Il s'est agit d'une étude transversale effectuée de décembre 2012 à janvier 2013 à Dakar. Les données ont été recueillies, après consentement, sur fiche d'enquête anonyme soumise à toute personne volontaire vivant en couple et résidant à Dakar. L'analyse statistique a été effectuée avec le logiciel SPSS 13.0. Le nombre de personnes victimes de violences conjugales était de 60 soit 37,30% dont 31 femmes (51,70%) et 29 hommes (48,30%). Le sex-ratio était de 0,93. Parmi les victimes, 53 étaient scolarisées soit 88,30%. Le régime matrimonial était de type monogame dans 39 cas (65%) et polygame dans 21 cas (35%). La vie en couple durait depuis moins de 11 ans dans 60% des cas et durait de 11 ans à 20 ans au plus dans 26,6% des cas. L’étude des types de violences montrait la fréquence des agressions physiques. Les armes utilisées étaient surtout les armes naturelles. Les principaux facteurs de risque de violence conjugale sont les facteurs sociodémographiques, culturels et économiques comme le jeune âge, l'inégalité du genre, les jeunes couples, la précarité, le niveau d'instruction élevé. La prise en charge des victimes et la prévention du phénomène restent insuffisantes dans nos pays. PMID:26918077

    The Winter School held in Les Houches on March 12-21, 1985 was devoted to Semiconductor Heterojunctions and Superlattices, a topic which is recognized as being now one of the most interesting and active fields in semiconductor physics. In fact, following the pioneering work of Esaki and Tsu in 1970, the study of these two-dimensional semiconductor heterostructures has developed rapidly, both from the point of view of basic physics and of applications. For instance, modulation-doped heterojunctions are nowadays currently used to investigate the quantum Hall effect and to make very fast transistors. This book contains the lectures presented at this Winter School, showing in particular that many aspects of semiconductor heterojunctions and super­ lattices were treated, extending from the fabrication of these two-dimensional systems to their basic properties and applications in micro-and opto-electron­ ics. Among the subjects which were covered, one can quote as examples: molecular beam epitaxy and metallorgani...

    Summary Les vols de biens fabriqués avec le cuivre semblent en hausse depuis un certain temps du fait de son prix élevé de revente, ce qui est à l’origine d’une augmentation du nombre d’accidents électriques par haut voltage (AEHV) qui sont graves du fait des brûlures profondes qu’elles provoquent le long des axes vasculo-nerveux. Les Auteurs rapportent une série de neuf cas d’AEHV traités au service de chirurgie plastique et de brûlés de l’Hôpital Ibn Sina de Rabat, Maroc, à travers laquelle ils étudient les caractéristiques épidémiologiques, cliniques et thérapeutiques. La population intéressée était jeune et active. Les brûlures étaient secondaires à un contact avec des câbles à haute tension lors de tentatives de vol par arrachement de conducteurs en cuivre dans les transformateurs dans 67% des cas, et lors de tentatives de coupure de caténaires alimentant les trains électriques sur le réseau ferroviaire dans 33% des cas. Le traitement des lésions électrothermiques a nécessité des interventions itératives avec amputation et désarticulation des segments de membres nécrosés dans 66% des cas, dont les suites étaient marquées par des séquelles fonctionnelles invalidantes. La prévention de ce type d’AEHV reste fondamentale. PMID:22262961

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

    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.

    The organization called "Les Impatients" was founded in 1992. Using a unique model, Les Impatients welcomes those with mental health issues who would like to express themselves through art. Les Impatients offers free creative workshops and encourages exchanges with the community through the sharing of its participants' creations. The name Les Impatients reinforces the idea that the organization does not consider those attending its workshops as patients, but rather creators who are eager to heal, develop their craft and find their place in society. The participants contribute to the collective objective of breaking down the stigma that surrounds mental illness.Les Impatients collaborates with various mental health organizations in Quebec, such as the Institut universitaire en santé mentale de Montréal (IUSMM) affiliated to the Université de Montréal, Douglas Mental Health University Institute (DMHUI), the Centre de santé et services sociaux Drummond (CSSS Drummond) and the Centre de santé et services sociaux Pierre-Boucher (CSSS Pierre-Boucher). Les Impatients offers more than 48 workshops in eight different locations to around 450 participants each week.Dissemination activities, remarkable events, original projects: Les Impatients stands out through its realizations. Examples are exhibitions, collections of love letters, comic books, CD, concerts, and reading nights. The organization's originality resides in the exploration of the links between the work of the participants and that of professional artists. An illustration of this interest is the annual Parle-moi d'amour auction-exhibition, which has been one of Les Impatients' major events since 1999.As part of its mission, Les Impatients conserves the works of art created by the participants during the workshops. Its collection includes more than 15,000 works of art from Les Impatients as well as pieces donated by collectors of unconventional art, commonly known as "art brut" or "outsider art". The

    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 viewpoint reviews renewable energy development in 14 markets that differ in market structure (restructured vs. not restructured), use of feed-in-tariff (FIT) (yes vs. no), transmission planning (anticipatory vs. reactive), and transmission interconnection cost allocated to a renewable generator (high vs. low). We find that market restructuring is not a primary driver of renewable energy development. Renewable generation has the highest percent of total installed capacity in markets that use a FIT, employ anticipatory transmission planning, and have loads or end-users paying for most, if not all, of the transmission interconnection costs. In contrast, renewable developers have been less successful in markets that do not use a FIT, employ reactive transmission planning, and have generators paying for most, if not all, of the transmission interconnection costs. While these policies can lead to higher penetration of renewable energy in the short run, their high cost to ratepayers can threaten the economic sustainability of renewable energy in the long-run. - Highlights: → Market structure seems to have little effect on renewable energy development. → Renewable energy development is more successful in markets that use a FIT. → Anticipatory transmission planning aids renewable energy development. → Low interconnection costs for developers also aids renewable energy development.

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    2010-01-01

    Public policy and funding are basically different, but both are needed to develop the renewable energy market. Public policy creates incentives, but also obligations. The setting up of a 'repurchase rate' also called a 'feed-in tariff' or 'clean energy cash back scheme' obliges electric power companies to buy back energy of renewable origin at a fixed, guaranteed rate. The extra-cost generated, although usually low, is passed on to all customers and does not cost the State anything. Funding is characterized by its source, the manner in which it is obtained and who supplies it, whether it be banks, mutual funds, development agencies, electric power companies, local governments or the consumers themselves. Repurchasing yields regular cash flows over a given period at a lower risk and allows banks to provide funding. This is one of the reasons for its success. This solution is also very popular with political leaders because it does not weigh down public funding. Both these reasons explain why repurchasing is so appreciated in Europe and in a growing number of countries, more than seventy having adopted it in 2010. In addition, it is regularly discounted in relation to technological breakthroughs and lower costs. As is the case in Europe, the problem lies in maintaining an acceptable rate while avoiding excessive project profitability. In Europe, for instance, the number of renewable energy projects is such that consumers are starting to complain about seeing their electricity rates rise because of the famous feed-in tariff, even though the cost of renewable energies continues to drop on a regular basis. The United States and a few other countries, including China, prefer the quota system, or RPS (Renewable Portfolio Standards), which requires electric power companies to generate a minimal share of electric power by a renewable energy source. These companies consequently invest in renewable energy projects or purchase this energy from other suppliers. Like the

    Accurate characterization of incoming atmospheric boundary layer (ABL) turbulence is a critical factor in improving accuracy and predictive nature of simulation of wind farm flows. Modern commercial wind turbines operate in the log layer of the ABL that are typically simulated using wall-modeled large-eddy simulation (WMLES). One of the long-standing issues associated with wall modeling for LES and hybrid RANS-LES for atmospheric boundary layers is the over-prediction of the mean-velocity gradient, commonly referred to as log-layer mismatch. Kawai and Larsson in 2012, identified under-resolution of the near-wall region and the incorrect information received by the wall model as potential causes for the log-layer mismatch in WMLES of smooth-wall boundary-layer flows. To solve the log layer mismatch issue, they proposed linking the wall model to the LES solution at a physical of height of ym, instead of the first grid point. In this study, we extend their wall modeling approach to LES of the rough-wall ABL to investigate issues of log-layer mismatch and grid convergence. This work was funded by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Wind Energy Technologies Office, under Contract No. DE-AC36-08-GO28308 with the National Renewable Energy Laboratory.

    Renewable energy technologies increase their hold across developing and emerging economies throughout the year The year 2016 saw several developments and ongoing trends that all have a bearing on renewable energy, including the continuation of comparatively low global fossil fuel prices; dramatic price declines of several renewable energy technologies; and a continued increase in attention to energy storage. For the third consecutive year, global energy-related carbon dioxide emissions from fossil fuels and industry were nearly flat in 2016, due largely to declining coal use worldwide but also due to improvements in energy efficiency and to increasing use of renewable energy. As of 2015, renewable energy provided an estimated 19.3% of global final energy consumption, and growth in capacity and production continued in 2016. The power sector experienced the greatest increases in renewable energy capacity in 2016, whereas the growth of renewables in the heating and cooling and transport sectors was comparatively slow. Most new renewable energy capacity is installed in developing countries, and largely in China, the single largest developer of renewable power and heat over the past eight years. In 2016, renewable energy spread to a growing number of developing and emerging economies, some of which have become important markets. For the more than 1 billion people without access to electricity, distributed renewable energy projects, especially those in rural areas far from the centralised grid, offer important and often cost-effective options to provide such access. The renewable energy sector employed 9.8 million people in 2016, an increase of 1.1% over 2015. By technology, solar PV and biofuels provided the largest numbers of jobs. Employment shifted further towards Asia, which accounted for 62% of all renewable energy jobs (not including large-scale hydropower), led by China. The development of community renewable energy projects continued in 2016, but the pace of

    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

    The author takes a look at causes of the present interest in the renewable, natural sources of energy. These are: the fuel deposits becoming exhausted, hazard to environment (especially carbon dioxide) and accessibility of these sources for under-developed countries. An interrelation is shown between these sources and the energy circulations connected with atmosphere and ocean systems. The chief ones from among them that are being used now are discussed, i.e. solar radiation, wind, water waves energy, tides, geothermal heat, and the like. Problems of conversion of the forms of these kinds of energy are also given a mention. (author)

    The economic contribution of the CEPA (Canadian Energy Pipeline Association) member companies to Canada's trade balance was discussed. CEPA member companies transport 95 per cent of the crude oil and natural gas produced in Canada to domestic and export markets. This represents a total of 5.6 Tcf of gas annually. Half of Canada's natural gas and oil production is exported to U.S. markets. All of these exports are transported by pipeline. CEPA member companies operate 90,000 km of pipeline from British Columbia to Quebec. Expansions are needed as a result of a significant increase in demand for natural gas and crude oil since 1990. Several issues exist for regulatory renewal. They include the need to create a level playing field, the overseeing of tolls and contract renewal terms, changing risk/reward trade-offs, the right to confidentiality of information and price discovery mechanism. The drivers for regulatory reform at Westcoast Energy are the need for pricing flexibility, customers desire for toll certainty, decontracting and opposition to rolled-in expansions for gathering and processing. An overview of Westcoast Energy's negotiated toll settlement, its implications, and the components of Westcoast Energy's 'light handed regulation' (LHR) was presented

  12. Renewable Energy Marketplace

    Science.gov (United States)

    Ghadimian, Vachik

    The renewable energy sector is evolving, and today, renewable energy has become a viable alternative for many facilities. Because this sector is in its infancy stage, lack of experience has resulted in failing solar projects. This project involves the design and implementation of a functioning web application that streamlines and automates the planning, risk assessment and financing of a solar development project. The three key stakeholders, the host facility, solar installer and financier are seamlessly integrated into a single marketplace. By designing a project development workflow, projects are vetted early on and terminated if deemed infeasible, saving time and resources. By risk assessing the project using the proposed scoring model, one can inherit more confident investors. The project scoring model also serves as a debt rating system, where investors can measure the risk/rewards. The platform will also serve as a communication medium between the three stakeholders. Besides storing documents like engineering drawings, permits, etc., the platform auto-generates all necessary transactional documents, legal documents and agreements among the three stakeholders.

    Two renewable electricity bills have been proposed in Congress since 2005 in Mexico. The first one was rejected by the Senate and the second one was approved by both the House of Representatives and the Senate in October 2008. Our objective is to explain the nature of both bills and to analyze each of them bearing in mind the Mexican electricity sector management scheme. In the Mexican electricity sector single-buyer scheme, the state-owned companies (Comision Federal de Electricidad and Luz y Fuerza del Centro) are responsible of the public services and the private sector generates electricity under six modalities: self-supply, cogeneration, independent production, small production, export, and import, which are not considered a public service. This scheme has caused controversies related to the constitutionality of the 1992 Power Public Services Law that allowed this scheme to be implemented. Both bills, the rejected one and the approved one, were formulated and based on that controversial law and their objectives are linked precisely more to the controversial issues than to the promotion of renewable electricity technologies; consequently, the gap among environmental, economic and social issues related with sustainability notion is wider.

  17. Economics of nuclear and renewables

    Khatib, Hisham; Difiglio, Carmine

    2016-01-01

    This paper provides an assessment of the economic challenges faced by both nuclear power and “new” renewable electricity technologies. The assessment reflects the need to incorporate new renewables into power grids and issues faced in dispatching power and their effect on traditional electricity technologies as well as the need for transmission extension and/or grid reinforcement. Wider introduction of smart grids and the likely demise of nuclear in some OECD countries are bound to enhance the future prospects for new renewables. However, their immediate future expansion will depend on continued subsidies, which are becoming difficult to sustain in present economic circumstances. Development of large energy storage facilities and carbon pricing could significantly enhance future renewable energy prospects. Correspondingly, expanding renewable energy, in spite of their popularity with some governments and sections of the public, is likely to face challenges which will slow their present rapid progress. Nuclear is now shied away from in many industrialized countries and having mixed prospects in developing economies. In many instances, it suffers from high initial costs, long lead times and often excessive construction delays. Nuclear power also faces challenging risks – investment as well as regulatory. In contrast to renewables, its share of global energy consumption is declining. - Highlights: •Renewables are increasing their energy share. •Renewables system cost is higher than their production cost. •Nuclear share is not increasing and their costs are not reduced. •Discount rate and subsidies are important in economics of renewables and nuclear.

    Technology progresses made to reach new oil and gas resources (heavy crudes, buried deposits, ultra-deep offshore), to better exploit the available reserves (increase of the recovery ratio) and to reduce the costs will allow to enhance the hydrocarbon reserves and to durably extend the limits of the world energy supply. In a context where geopolitical uncertainties, high price rates and pessimistic declarations increase once again the public fear about petroleum reserves, the French institute of petroleum (IFP) wanted to make a status about the essential role that technology can play in this challenge. This document gathers the transparencies and articles presented at this press conference: how to increase and renew oil and gas reserves, technology advances and research strategy of IFP (O. Appert, J. Lecourtier, G. Fries); how to enhance oil recovery from deposits (primary, secondary and tertiary recovery: polymers injection, CO{sub 2} injection, steam injection, in-situ oxidation and combustion, reservoir modeling, monitoring of uncertainties); the heavy crudes (the Orenoque extra-heavy oil, the tar sands of Alberta, the heavy and extra-heavy crudes of Canada, IFP's research); ultra-deep offshore (the weight challenge: mooring lines and risers, the temperature challenge: paraffins and hydrates deposition, immersion of the treatment unit: economical profitability of satellite fields); fields buried beyond 5000 m (technological challenges: seismic surveys, drilling equipment, well logging, drilling mud; prospects of these fields); oil reserves: data that change with technique and economy (proven, probable and possible reserves, proven and declared reserves, three converging evaluations about the world proven reserves, reserves to be discovered, non-conventional petroleum resources, technical progress and oil prices, production depletion at the end of the century).

    Demming, Anna

    2011-06-01

    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.

    Acrylonitrile (ACN) is a petroleum-derived compound used in resins, polymers, acrylics, and carbon fiber. We present a process for renewable ACN production using 3-hydroxypropionic acid (3-HP), which can be produced microbially from sugars. The process achieves ACN molar yields exceeding 90% from ethyl 3-hydroxypropanoate (ethyl 3-HP) via dehydration and nitrilation with ammonia over an inexpensive titanium dioxide solid acid catalyst. We further describe an integrated process modeled at scale that is based on this chemistry and achieves near-quantitative ACN yields (98 +/- 2%) from ethyl acrylate. This endothermic approach eliminates runaway reaction hazards and achieves higher yields than the standard propylene ammoxidation process. Avoidance of hydrogen cyanide as a by-product also improves process safety and mitigates product handling requirements.

    In 1987 an American-style fridge freezer would use about 950 kWh of electricity and cost about 150 (£80) a year to run. Two decades on, a comparable appliance uses half the electricity and costs less than half as much to run. In 1975 there were about 3780 000 cars on the streets of Los Angeles, whereas today there are more than 5200 000 - yet air-pollution levels have fallen by half and an increasing number of those vehicles are hybrids or rely on renewable fuels like bio-diesel. Last year, half a million homes in Southern California were receiving direct solar power, either from solar electricity plants or from rooftop photovoltaic panels.

    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.

    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.

  10. Renewal of radiological equipment.

    Science.gov (United States)

    2014-10-01

    In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. 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.

    Full Text Available Malgré son inactualité apparente, La Tentation de Saint Antoine se rattache à une série de savoirs, de recherches historiques, d’interrogations qui caractérisent son époque et définissent une configuration épistémologique. Les savoirs sont impliqués à deux niveaux : dans l’organisation de la poétique de l’œuvre, dans les représentations de l’œuvre. Flaubert utilise des savoirs historiques, anthropologiques et psychiatriques qui légitiment l’organisation du texte et les déconstruit en même temps. Il invente une nouvelle forme de grotesque – le grotesque des idées – et met en abyme un questionnement sur les savoirs qui évolue de la première Tentation à celle de 1874.Despite its apparent irrelevancy to Flaubert's time, La Tentation de Saint Antoine is linked to a net of knowledge, historical research, questions that characterize a period and define an epistemological configuration. These types of knowledge are at play on two levels: in the organization of the poetics of the work and in its representations. Flaubert uses historical, anthropological and psychiatric knowledge which legitimates the organization of the text while at the same time he deconstructs this body of knowledge. Flaubert invents a new form of grotesque – the grotesque of ideas – and, in a mise-en-abyme from the first Tentation to the 1874 version, he questions these fields of knowledge.

    Full Text Available The UK is said to have the largest number of CCTV cameras of any European nation. These cameras have been involved in a variety of changes in UK police practices. Such changes range from new evidential practices in court cases, through access to new materials, to new questions posed regarding invasions of privacy. One unexplored area of police practices, which this paper will argue have undergone significant changes since the introduction of CCTV cameras, is police accountability. This paper will draw on recent controversies in the UK regarding police car chases to investigate the ways in which CCTV cameras have led to new and complex questions of police accountability.Le Royaume-Uni est souvent présenté comme le pays ayant le plus grand nombre de caméras en Europe. Ces caméras ont joué un rôle dans bien des changements intervenus au sein des pratiques de la police britannique, depuis la production de nouveaux types de preuves devant les tribunaux, en passant par l’accès à de nouveaux matériaux et à de nouvelles informations, jusqu’à la mise en lumière de nouvelles questions touchant aux violations de la vie privée. Un des aspects peu explorés parmi ces nouvelles pratiques policières concerne la question de la responsabilité et le fait, pour la police, de rendre des comptes. Cet article porte précisément sur les changements significatifs provoqués par l’introduction de caméras de vidéosurveillance dans la façon d’accomplir les activités policières. À partir du cas de controverses récentes au Royaume-Uni autour de courses poursuites dans lesquelles sont engagés des véhicules de police, il s’intéressera aux façons dont la présence et l’usage de caméras de vidéosurveillance ont amené des questions à la fois nouvelles et complexes, concernant la justification des actions de police.

    2016-03-01

    Renewable energy sources (RES) are low-carbon energies available right within our borders, and as such can be of great value in addressing the challenges of climate change and energy security. In 2014, renewable energies accounted for 14.6% of France's gross final energy consumption. The French Energy Transition Act for Green Growth sets renewables targets of 23% and 32% as a share of gross final energy consumption by 2020 and 2030, respectively. However, renewable energies are still more costly than conventional energies. A significant share of this additional cost is borne by energy consumers, particularly in the form of energy taxation and biofuels blending obligations. Public aid is also provided to support heat production from renewable energy sources (RES-H). The two most significant aids available today are the Energy Transition Tax Credit (CITE) and the Heat Fund. Comparing the various types of renewable energies shows sharp disparities in terms of the cost of avoiding one tonne of CO 2 , which ranges from euros 59 to more than euros 500 for electricity production it follows that the cost of the energy transition is likely to vary significantly depending on which renewable energy sources are pushed to the fore. The combustion of biomass for heat production appears to offer an economically efficient way to reduce CO 2 emissions. Of the various renewable technologies available for the production of electricity (with the exception of hydropower, which was excluded from the scope of this study), onshore wind power is the least costly

    2007-07-01

    Renewable energies are essential contributors to the energy supply portfolio as they contribute to world energy supply security, reducing dependency on fossil fuel resources, and provide opportunities for mitigating greenhouse gases. Differences in definition and lack of adequate data complicated the discussion between participants on these key issues. The International Energy Agency believes that this fact sheet can be of use to all to facilitate the debate on the past, current and future place and role of renewables in total energy supply. Our goal is to present as objectively as possible the main elements of the current renewables energy situation. The definitions and coverage of national statistics vary between countries and organisations. In this fact sheet, the renewables definition includes combustible renewables and waste (CRW), hydro, geothermal, solar, wind, tide and wave energy.

    This article takes a look at the increased use of renewable forms of energy and, in particular, the so-called 'new renewables' that are the subject of discussion in Europe and Switzerland. The wide divergence between the political and economical viewpoints concerning renewables is examined and the question is posed on how political desires and economical sense can be brought closer together. Questions concerning the public acceptance of various forms of energy are looked at and the expectations placed on renewable forms of energy are commented on. Criteria for models of promotion are listed including CO 2 emissions, technology and cost efficiency, marketing aspects and flexibility. Also, aspects concerning plausibility, fairness and responsibility are looked at. A model named 'Swiss Renewables Model' is proposed and its efficiency, functionality and financing are discussed

    If one compares the progress in research and development of renewable energy applications with the finding which has been granted to these activities during the 23 years after the first oil shock, one cannot but be very impressed. It is indicated in this paper hoe comprehensive the potential of renewable energy is. One should take into account that the methods described form a broad interdisciplinary field in contrast to fossil and nuclear technologies. From technical point of view the present and future energy demand can be met by the broad spectrum of renewable energies in combination with energy conservation. Many of these techniques are already economically competitive: solar architecture, wind energy, hydropower, low temperature heat production, photovoltaic for remote areas, various types of biomass application, geothermal energy although not exactly renewable. The future of renewable energies will depend on opening markets for these techniques

    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.

  7. Renewal-anomalous-heterogeneous files

    International Nuclear Information System (INIS)

    Flomenbom, Ophir

    2010-01-01

    Renewal-anomalous-heterogeneous files are solved. A simple file is made of Brownian hard spheres that diffuse stochastically in an effective 1D channel. Generally, Brownian files are heterogeneous: the spheres' diffusion coefficients are distributed and the initial spheres' density is non-uniform. In renewal-anomalous files, the distribution of waiting times for individual jumps is not exponential as in Brownian files, yet obeys: ψ α (t)∼t -1-α , 0 2 >, obeys, 2 >∼ 2 > nrml α , where 2 > nrml is the MSD in the corresponding Brownian file. This scaling is an outcome of an exact relation (derived here) connecting probability density functions of Brownian files and renewal-anomalous files. It is also shown that non-renewal-anomalous files are slower than the corresponding renewal ones.

  8. Modeling renewable energy company risk

    International Nuclear Information System (INIS)

    Sadorsky, Perry

    2012-01-01

    The renewable energy sector is one of the fastest growing components of the energy industry and along with this increased demand for renewable energy there has been an increase in investing and financing activities. The tradeoff between risk and return in the renewable energy sector is, however, precarious. Renewable energy companies are often among the riskiest types of companies to invest in and for this reason it is necessary to have a good understanding of the risk factors. This paper uses a variable beta model to investigate the determinants of renewable energy company risk. The empirical results show that company sales growth has a negative impact on company risk while oil price increases have a positive impact on company risk. When oil price returns are positive and moderate, increases in sales growth can offset the impact of oil price returns and this leads to lower systematic risk.

    International Nuclear Information System (INIS)

    Freris, L.; Infield, D.

    2009-01-01

    Power generation from renewable energy sources is different from power generation from classical energies (nuclear, thermal..). Therefore, the integration into the grid of the electricity supplied by renewable sources requires a deep thinking. The reason is that these power sources are controlled by variable elements, like wind, water and sun, which condition production. This book deals with the following aspects in detail: characteristics of classical and intermittent generators; grid balancing between supply and demand; conversion methods of renewable energies into electricity; power systems; privatizing of power generation and birth of new markets, in particular the 'green' power market; development of renewable energies thanks to technical advances. It gives a comprehensive overview of the present day available renewable energy sources for power generation. (J.S.)

    About 30 French main players in the field of energy (political parties, administrations, companies, non-governmental organizations and think-tanks) have been reported and dispatched on a chart according to their opinions following 2 axis: pro- versus anti-nuclear energy and pro- versus anti-wind power. The energy sector in France is dominated by 4 companies: EDF, GDF-Suez, Areva and Total, all are strongly pro-nuclear. All the political parties except EELV (Europe-Ecology-Les-Verts) are favourable to nuclear energy. Most non-governmental organizations are favourable to renewable energies, but the FED (Federation Environnement Durable) gathers local associations fighting the installations of wind turbines. (A.C)

    Full Text Available Les historiens français de la seconde moitié du XXe siècle sont plus conscients que leurs prédécesseurs que le travail de recherche et d’écriture de l’histoire est une interaction continuelle entre présent et passé. La plupart d’entre eux ont substitué le présent au passé simple comme temps de base de la narration. Ils sont plus attentifs aux tendances et aux phénomènes de longue durée qu’au temps court des événements. Ils sont moins réticents à étudier le passé le plus récent mais, sur ce point, la controverse n’est pas close. Ouvertement ou non, le récit chronologique demeure le modèle de plan prédominant, de même que continue à prévaloir un système de datation absolue se référant au calendrier. Les historiens font attention à éviter les coupures chronologiques abusives et prennent soin de ne pas suggérer qu’une séquence d’événements implique nécessairement une relation causale entre eux. Les débats théoriques se développent mais, le plus souvent, résultent d’incitations extérieures au corps des historiens.French historians of the second half of the XXe century are more aware than their predecessors that historical research and writing means continuous interaction between past and present. Most of them have substituted the grammatical present for the preterit as the basic tense of the narrative. They pay more attention to trends and long-term phenomena than to short-term events. They are less reluctant to study the most recent past, but this issue remains controversial. Openly or not, chronological story is still the prevailing model, as is the absolute dating system according to the calendar. Historians are careful to avoid arbitrary chronological divisions and they stress that a sequence of events does not imply a relationship of cause and effect between them.

    2012-10-01

    Full Text Available Cet article propose une discussion sur certains aspects contribuant à définir la victime de génocide, suggérant une sorte d’effritement des limites purement légales, à la faveur d’une définition de victime de génocide qui inclut toutes les voix, à la fois multiples et contrastantes, de ceux qui ont été témoins directs ou indirects du « crime des crimes ». La définition de victime du point de vue des circonstances concrètes est, en effet, difficile, complexe et susceptible de controverses, surtout face à un nombre élevé de victimes. Il est donc d’importance primordiale de créer un droit subjectif de la victime à l’indemnisation, qui peut être demandée aussi bien au coupable qu’à l’État. Des atrocités commises à grande échelle, comme c’est le cas du génocide, peuvent être prévenues grâce à une responsabilisation constante et rigoureuse de la société civile qui peut et doit être impliquée parce qu’elle est à la fois victime et capable de mettre en place des programmes de prévention et d’éducation à la non-violence. This paper suggests a discussion on some of the aspects which help forging a definition of victim of genocide, whilst proposing a sort of reshaping of purely legal limits, in favor of a definition that includes all the multiple and sometimes conflicting voices of those which are direct or indirect witnesses of the "crime of all crimes." The definition of victim of genocide is indeed difficult, complex and open to controversies, especially when we are dealing with a large number of casualties. Therefore, it is paramount to set up a legal framework where victims are entitled to both financial and moral compensation. Atrocities committed in large scale as in the case of genocide, can be prevented through constant and rigorous involvement of civil society which can, and should, be involved because society at large is a victim of genocide and because only civil society, as a whole

    Renewable energy markets, industries, and policy frameworks have evolved rapidly in recent years. The Renewables Global Status Report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by many contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecasts. This latest Renewables Global Status Report saw: a shift in investment patterns that led to a global decrease in clean energy investment; continuing growth in installed capacity due to significant technology cost reductions and increased investment in developing countries; renewables progressively supplementing established electricity systems, demonstrating that the implementation of suitable policies can enable the successful integration of higher shares of variable renewables; and the emergence of integrated policy approaches that link energy efficiency measures with the implementation of renewable energy technologies.

    The US Army Corps of Engineers has retained Idaho National Laboratory (INL) to conduct a study of past INL experiences and complete a report that identifies the processes that are needed for the development of renewable energy projects on government properties. The INL has always maintained expertise in power systems and applied engineering and INL’s renewable energy experiences date back to the 1980’s when our engineers began performing US Air Force wind energy feasibility studies and development projects. Over the last 20+ years of working with Department of Defense and other government agencies to study, design, and build government renewable projects, INL has experienced the do’s and don’ts for being successful with a project. These compiled guidelines for government renewable energy projects could include wind, hydro, geothermal, solar, biomass, or a variety of hybrid systems; however, for the purpose of narrowing the focus of this report, wind projects are the main topic discussed throughout this report. It is our thought that a lot of what is discussed could be applied, possibly with some modifications, to other areas of renewable energy. It is also important to note that individual projects (regardless the type) vary to some degree depending on location, size, and need but in general these concepts and directions can be carried over to the majority of government renewable energy projects. This report focuses on the initial development that needs to occur for any project to be a successful government renewable energy project.

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2011. The report covers both current status and key trends; by design, it does not provide analysis or forecast the future. Global energy consumption rebounded in 2010 after an overall downturn in 2009. Renewable energy, which experienced no downturn in 2009, continued to grow strongly in all end-use sectors - power, heat and transport - and supplied an estimated 16% of global final energy consumption. Renewable energy accounted for approximately half of the estimated 194 gigawatts (GW) of new electric capacity added globally during the year. Renewables delivered close to 20% of global electricity supply in 2010, and by early 2011 they comprised one quarter of global power capacity from all sources. In several countries, renewables represent a rapidly growing share of total energy supply, including heat and transport

  7. Les AOC dans la mondialisation

    Jean-Claude Hinnewinkel

    2004-12-01

    Full Text Available Fruit du conflit plusieurs fois séculaire entre les producteurs et le négoce, le terroir vitivinicole est né de phénomènes de « distinction » qui en Bordelais donnent les « crus ». Ces terroirs de production identifiés, il fallut les faire durer, face à conjoncture, face au négoce. Les réussites les plus nettes sont le résultat d’un projet collectif dont l’AOC à la française est l’une des plus spectaculaires. Renforcer le terroir, compris comme un espace de production géré par les producteurs, devient alors une des conditions essentielles de la durabilité du système. L’avenir des AOC réside sans doute dans une meilleure gestion du conflit négoce/production par l’interprofession mais aussi (surtout ! dans un renforcement de la gestion de la production au sein de l’aire de production qu’est le terroir. L’avenir du terroir relève de la gouvernance de cette aire de production avec trois partenaires : la puissance publique (INAO, l’interprofession et le syndicat des producteurs. Se pose dès lors la question du partage des compétences et la durabilité des AOC paraît liée en grande partie à une définition claire du rôle et donc du statut des syndicats de producteurs, à une véritable gouvernance locale, seule capable de donner du sens à l’ancrage géographique des vins dits de « terroir ». Mais alors ne faut-il pas impliquer un troisième partenaire, la société locale toute entière à travers ses représentations démocratique et associative ?Resulting from century-long conflicts between producers and merchants, vineyards have developped out of "distinction" phenomenons which in the Bordeaux region gave birth to "crus" (vintages. Such identified terroirs had to be defended: the French collective AOC (Denomination of Origin project is one of the most spectacular success. The terroir, as production territory organized by producers, is one of the essential conditions for sustainability

  11. Renewable, ethical? Assessing the energy justice potential of renewable electricity

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Energy justice is increasingly being used as a framework to conceptualize the impacts of energy decision making in more holistic ways and to consider the social implications in terms of existing ethical values. Similarly, renewable energy technologies are increasingly being promoted for their environmental and social benefits. However, little work has been done to systematically examine the extent to which, in what ways and in what contexts, renewable energy technologies can contribute to achieving energy justice. This paper assesses the potential of renewable electricity technologies to address energy justice in various global contexts via a systematic review of existing studies analyzed in terms of the principles and dimensions of energy justice. Based on publications including peer reviewed academic literature, books, and in some cases reports by government or international organizations, we assess renewable electricity technologies in both grid integrated and off-grid use contexts. We conduct our investigation through the rubric of the affirmative and prohibitive principles of energy justice and in terms of its temporal, geographic, socio-political, economic, and technological dimensions. Renewable electricity technology development has and continue to have different impacts in different social contexts, and by considering the different impacts explicitly across global contexts, including differences between rural and urban contexts, this paper contributes to identifying and understanding how, in what ways, and in what particular conditions and circumstances renewable electricity technologies may correspond with or work to promote energy justice.

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2010. The report covers both current status and key trends. By design, the report does not provide analysis, discuss current issues, or forecast the future. Many of the trends reflect the increasing significance of renewable energy relative to conventional energy sources (including coal, gas, oil, and nuclear). By 2010, renewable energy had reached a clear tipping point in the context of global energy supply. Renewables comprised fully one quarter of global power capacity from all sources and delivered 18 percent of global electricity supply in 2009. In a number of countries, renewables represent a rapidly growing share of total energy supply-including heat and transport. The share of households worldwide employing solar hot water heating continues to increase and is now estimated at 70 million households. And investment in new renewable power capacity in both 2008 and 2009 represented over half of total global investment in new power generation. Trends reflect strong growth and investment across all market sectors-power generation, heating and cooling, and transport fuels. Grid-connected solar PV has grown by an average of 60 percent every year for the past decade, increasing 100-fold since 2000. During the past five years from 2005 to 2009, consistent high growth year-after-year marked virtually every other renewable technology. During those five years, wind power capacity grew an average of 27 percent annually, solar hot water by 19 percent annually, and ethanol production by 20 percent annually. Biomass and geothermal for power and heat also grew strongly. Much more active policy development during the past several years culminated in a significant policy milestone

    In the kidney of the gerbil in oliguria there exists a cortico-papillary gradient in the concentration of the sodium and of the urea; this gradient disappears in the gerbil kidney in osmotic diuresis or in the rat kidney in aqueous diuresis; in these three states of diuresis there is no significant difference in the potassium concentration between the surface and interior regions of the kidneys. Kinetic studies using tritiated water, urea {sup 14}C and {sup 24}Na show that water and urea in the interior regions of the kidney are only renewed very slowly (1 h) whereas the sodium is rapidly changed (1 mn). These results can be explained using WIRZ's theory concerning the mechanism of the counter-current concentration of urine. Furthermore, the evolution of the specific radioactivity of urea {sup 14}C is favorable for a cortical synthesis of urea. (author) [French] II existe dans le rein de Merions en oligurie un gradient cortico papillaire de la concentration du sodium et de l'uree; ce gradient est aboli dans le rein de Merions en diurese osmotique ou de rats en diurese aqueuse; dans ces 3 etats de diurese il n'y a pas de difference significative de la concentration du potassium entre les regions superficielles et profondes des reins. Des etudes cinetiques a l'aide d'eau tritiee, d'uree {sup 14}C et de {sup 24}Na montrent que l'eau et l'uree des regions profondes des reins ne sont renouveles que tres lentement (1 h), alors que le sodium est tres vite renouvele (1 mn). Ces resultats s'expliquent par la theorie de WIRZ sur le mecanisme de la concentration de l'urine par contre-courant. En outre, l'evolution renale de la radioactivite specifique de l'uree {sup 14}C est en faveur d'une synthese corticale de l'uree. (auteur)

It also shows that European Union is not a leader in renewable energies any more, that some European countries are changing sides, that figures and trends must be carefully compared with those in the field of fossil and nuclear energies, that all energies are not all the same, that jobs and system integration are also important, that investments and attractiveness of countries in renewable energies must be assessed, and that a mobilisation on small scale and consumer-based renewable energies is required. Ten recommendations are made for France to support the EU leadership development

    2017-01-01

    The first version of REN21's Renewables Global Futures Report (GFR) published in January 2013 identified a panorama of likely future debates related to the renewable energy transition. As a reflection of the wide range of contemporary thinking by the many experts interviewed for the report, it did not present just one vision of the future but rather a 'mosaic' of insights. Given the positive feedback in response to the first edition, a new edition has been prepared, continuing where the last one left off. The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. The questionnaire for the survey was developed in close cooperation between the REN21 Secretariat, the Institute for Sustainable Future (ISF) of the University of Technology Sydney/Australia (UTS) and the Institute for Advanced Sustainability Studies (IASS) in Potsdam/Germany. It covered the following topics: 1. How much renewables?; 2. Power sector; 3. Heating and cooling; 4. Transport; 5. Storage; 6. Demand-side management and energy efficiency; 7. Integration of sectors; 8. Macro-economic considerations; 9. Technology and costs; 10. Policy; 11. Cities; 12. Distributed renewable energy/energy access; 13. Barriers/challenges/enablers. 114 experts were interviewed in total; the average interview time was approximately one hour. The interviews were conducted between May and October 2016. The questionnaire was also mirrored in an online version and used both by interviewers and interviewees to record the interview process. Interviewees were selected from the following regions: Africa, Australia and Oceania, China, Europe, India, Japan, Latin America

    2008-01-01

    On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

    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)

    Full Text Available Les Fleurs bleues, roman paru en 1965, propose un fascinant voyage dans le temps et dans l'espace géographique des langues, une odyssée au cœur de la problématique babélienne dont il se fait le porte-parole. Queneau joue sur les particularités linguistiques, les idiolectes et les syntaxes dans une perspective transhistorique et cosmopolite, créant un nouvel esperanto romanesque : le « néobabélien ». Toutes les langues s'interpénètrent et se correspondent, enrichissent l'écriture de l'œuvre et dévoilent peu a peu ses prolongements à la fois scientifiques et philosophiques. Queneau élabore ainsi son propre système linguistique et littéraire, dans ce laboratoire de l'arche romanesque, où la langue future est en gestation.Reprenant le flambeau de Noé, l'écrivain entraîne ses lecteurs dans une traversée du déluge qui mêle le rêve et la réalité, l'humour et la nostalgie – celle de la langue unique, la virtuosité du style et la rigueur de la composition. Le roman démantèle les frontières historiques et géographiques, faisant ainsi de Noé une nouvelle figure de l'artiste, sauveur et reconstructeur du Verbe, et chantre de l'infinie potentialité du langage. Non sans humour, son esthétique se fonde sur une dialectique de la contrainte et de la liberté, de la destruction et de la reconstruction, soutenue par un style vif et corrosif. Le conteur, le poète et le mathématicien se rejoignent et conjuguent leur sagesse dans ce roman complexe et déroutant, récit à clés d'une expérience linguistique originale et approfondie.The novel Les Fleurs bleues, which was published in 1965, is an invitation to a fascinating journey into the time and space dimensions of languages, an odyssey into the heart of the Babelian problematics which it publicizes. Queneau plays upon linguistic particularities, idiosyncrasies and syntaxes within a historical and cosmopolitan perspective, and creates a new Esperanto for the novel: the

Cet article propose pour le Reynou une analyse de documents figurés anciens permettant de préciser la chronologie des travaux du château et du parc. Pour Mont-Méry il s’agit de poser de nouveaux jalons pour une étude plus approfondie des sources et de la composition des jardins afin d’envisager de nouvelles pistes pour leur attribution.The Reynou and Mont-Méry parks near Limoges originally belonged to the city’s porcelain manufacturers, the Havilands. Both parks are of considerable interest in terms of their landscaping and their botany. In both cases, there is some uncertainty as to the identity of their designers. This article offers an analysis of the graphic representations of the Reynou park, clarifying the chronology of the creation of the château and its park. For the Mont-Méry park, the aim is to offer some guidelines for further research in the source material and on the design of the park itself, perhaps allowing for the designer to be identified.

  6. Interactions between renewable energy policy and renewable energy industrial policy: A critical analysis of China's policy approach to renewable energies

    International Nuclear Information System (INIS)

    Zhang, Sufang; Andrews-Speed, Philip; Zhao, Xiaoli; He, Yongxiu

    2013-01-01

    This paper analyzes China's policy approach to renewable energies and assesses how effectively China has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. First we briefly discuss the interactions between these two policies. Then we outline China's key renewable energy and renewable industrial policies and find that China's government has well recognized the need for this policy interaction. After that, we study the achievements and problems in China's wind and solar PV sector during 2005–2012 and argue that China's policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself, and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. Lastly, we make an in-depth analysis of the three ideas underlying this policy approach, that is, the green development idea, the low-carbon leadership idea and indigenous innovation idea. We conclude that Chinas' policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy. The paper contributes to a deeper understanding of China's policy strategy toward renewable energies. -- Highlights: •Interactions between renewable energy policy and renewable energy industrial policy are discussed. •China's key renewable energy and renewable energy industrial policies are outlined. •Two empirical cases illustrate China's policy approach to renewable energies. •We argue that China needs to enhance the interactions between the two policies. •Three ideas underlie China's policy approach to renewable energies

    Full Text Available The Energy-CSOP facilitates broad equity participation of citizens without assets or savings in a regulated public energy utility. As the CSOP is designed for regulated markets with guaranteed prices, regulated market access and long-term relationships between producer and consumer, the energy market is predestined. A CSOP trust can be set up for a renewable energy plant (e.g., a biogas reactor, a solar panel, a windmill or a geothermic drill. European states have set an ambitious target to reach 20% share of energy from renewable sources by 2020. Germany as Europe’s green energy leader could become a pioneer in CSOP implementation. Small communities in Europe would benefit from the increased share of renewable energy resources.

  9. Renewable energies. Italy is mobilizing

    International Nuclear Information System (INIS)

    Marante, W.

    2005-01-01

    About 3 quarter of the Italian electric power comes from fossil fuel power plants. The rest is generated from hydropower, few comes from biomass and wind energy and a very few from geothermal energy (2% of the national production). However, the situation is changing and geothermal energy, with only 5 TWh, makes Italy the European leader in this domain and the world number 4 behind USA, Philippines and Mexico. The renewable sources represent 18.5% of the total Italian energy production. During the last five years, the renewable energy sources have developed rapidly: +80% per year for the wind energy, +32% per year for biomass and about +3% per year for geothermal energy. Moreover, the Italian government is implementing incentives for the development of renewable energy sources. This article gives an overview of the situation. (J.S.)

  10. China's renewable energy policy: Commitments and challenges

    International Nuclear Information System (INIS)

    Wang Feng; Yin Haitao; Li Shoude

    2010-01-01

    The passing of the Renewable Energy Law (REL) in 2005 demonstrated China's commitment to renewable energy development. In the 3 years after the REL, China's renewable electricity capacity grew rapidly. From 2006 to 2008, China's wind capacity installation more than doubled every year for 3 years in a row. However, three facts prevent us from being optimistic about China's renewable electricity future. First, considered as a share of total capacity, renewable electricity capacity is decreasing instead of increasing. This is due simply to the rapid growth of fossil fuel capacity. Second, a significant amount of renewable generation capacity is wasted because it is not connected to the electricity grid. Finally, renewable electricity plants are running at a low level of efficiency. Based on an in-depth analysis of China's existing renewable energy policy, we suggest that these challenges should be dealt with by introducing a market-based mandatory renewable portfolio requirement coupled with strong regulatory monitoring of grid enterprises.

  12. Renewable energy technology acceptance in Peninsular Malaysia

    International Nuclear Information System (INIS)

    Kardooni, Roozbeh; Yusoff, Sumiani Binti; Kari, Fatimah Binti

    2016-01-01

    Despite various policies, renewable energy resources have not been developed in Malaysia. This study investigates the factors that influence renewable energy technology acceptance in Peninsular Malaysia and attempts to show the impact of cost and knowledge on the perceived ease of use and perceived usefulness of renewable energy technology. The results show that cost of renewable energy has an indirect effect on attitudes towards using renewable energy through the associated impact on the perceived ease of use and perceived usefulness. The results also indicate that public knowledge in Peninsular Malaysia does not affect perceived ease of use, although the positive impact of knowledge on perceived usefulness is supported. Furthermore, our results show that the current business environment in Peninsular Malaysia does not support the adoption of renewable energy technology, and thus, renewable energy technology is not commercially viable in Peninsular Malaysia. Additionally, the population of Peninsular Malaysia associates the use of renewable energy with a high level of effort and therefore has a negative attitude towards the use of renewable energy technology. There is, therefore, a definite need to pay more attention to the role of public perception and awareness in the successes and failures of renewable energy policy. - Highlights: • Public acceptance is an essential element in the diffusion of renewable energy. • Perceived ease of use and perceived usefulness affect intention to use renewables. • It is important to reduce the cost of renewable energy, particularly for end users. • Renewable energy policies should address issues of public perception and awareness.

    Dessus, B; Devin, B; Pharabod, F

    1991-07-01

    A comprehensive analysis, region by region, of the actually accessible renewable energies at a given horizon, is presented. The same methodology as the one employed to derive ``proven fossil energy reserves`` from ``energy resources`` is adopted, in which resources are defined by quantitative information on physical potential, while reserves take into account technical and economical accessibility. As renewable resources are fluctuating with time and are diluted in space and not readily transportable or storeable, it is necessary to consider the presence of populations or activities near enough to be able to profit by these diluted and volatile energies.

    To judge future trends in work on the exploitation of renewable energy sources for overall energy supply, it is necessary to know the following: the rules that nature abides by, the principles of technical exploitation of these energies, and the basic data for the current state of development. The above information is compiled in this publication for those renewable energy sources on which topical discussion centres: solar radiation and wind. For the remaining renowable energy sources (e.g. biomass, tidal power, geothermal energy), some examples of use are mentioned and advanced literature is indicated. (orig./HSCH).

    2011-01-01

    The world has to face increasing energy needs while it is today dependent of fossil fuels at 80%. Getting out of the fossil fuels dependence model requires an important effort to promote the energy saving and the carbon-free energies as well, and in particular the renewable energy sources. Taking all this information into account, the authors evaluate the global share that renewable energies could represent in the energy mix, in France and in the entire world. This share represents today only 10% of the energy consumed, but will it remain marginal or will it become important and eventually prominent? (J.S.)

    This work expands upon Swallow's theoretical analysis of interactions between renewable and non-renewable resources. In this comment the interaction is such that the renewable resource prefers the non-renewable environment, as opposed to SwallowÕs (op cit) case of the non-renewable environment being essential to the renewable resource. We find that this difference strongly affects the results, and makes the resources change from being complements to being substitutes, i.e. in the essential ca...

Assuming constant variable marginal costs for both energy sources, convex adjustment costs and a more expensive renewable energy, we show the following. With sufficiently abundant non-renewable energy endowments, the dynamic equilibrium path is composed of a first time phase of only non-renewable energy use followed by a transition phase substituti...

  3. Renewable energy policy. Into the mainstream

    International Nuclear Information System (INIS)

    2003-01-01

    Renewable energy today is at a critical stage of development: renewable technologies are maturing, and costs for some technologies are in the competitive range. Beyond the energy they produce, renewable energy technologies offer a variety of other benefits towards the achievement of sustainable development goals. This promise has led to all IEA governments to support their greater development. But, while renewables markets are growing strongly, additional steps must be taken to accelerate the achievement of sustainable, large-scale markets. This report by the IEA's Renewable Energy Working Party outlines those steps, and the benefits of moving renewable energy into the mainstream

    Currently, vegetation accounts for 3 major types of energy sources, notably woody biomass, starches and vegetable oils. Bio-ethanol and biodiesel is produced from the fermentation of starches, such as sugar cane, beet sugar, sorghum, corn and potatoes. Biofuels can be produced from palm tree oil, coconut oil , soya oil, sunflower oil or any type of vegetable based oil. This article discussed energy efficiency issues and the environmental impact of developing these energies. In general, the lower energy efficiency of the starches can be attributed to the enzymes responsible for the catalysis. The article also reviewed the thermochemistry and energy efficiency regarding second generation fuels. It also discussed the burning of biomass, including woody biomass, forest waste and agricultural waste. 1 ref., 2 figs.

    IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

  14. The USNCR license renewal process

    International Nuclear Information System (INIS)

    Kuo, Pao-Tsin

    2002-01-01

    The US Congress promulgated a law in 1954, entitled 'Atomic Energy Act'. This Act states that operating licenses for commercial nuclear power plants are limited to a fixed term of 40 years, but they may be renewed for a period not to exceed 20 years. The terms were established mainly for economic considerations, not based on technical limitations. The U.S. Nuclear Regulatory Commission (USNRC) published the license renewal rule, Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54), in December, 1991. The rule has since been amended in May, 1995. The underlying principle of the rule is that the regulatory process is adequate for ensuring safety of operating plants. The regulatory process includes NRC's issuance of Orders, Bulletins, Generic Letters, and Information Notices, as well as a number of special inspections in addition to the continuous oversight and routine inspection activities performed by on-site inspectors. Because of this comprehensive regulatory process, compilation of the current license basis or re-verification of the current licensing basis is not considered necessary for a license renewal review. The USNRC also determined on the basis of the findings of its research programs that active structures and components are well maintained by the existing programs. Therefore, the focus of the license renewal review is on passive, long-lived structures and components and on time-limited ageing analyses. The time-limited ageing analyses are for those structures and components which were originally designed to a 40 year service life

    Renewable energy markets and policy frameworks have evolved rapidly in recent years. This report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by a network of more than 400 contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecast the future. As such, this report and subsequent editions will serve as a benchmark for measuring global progress in the deployment of renewable energy, which is of particular interest in this International Year of Sustainable Energy for All. UN Secretary-General Ban Ki-moon has marked the occasion with a new global initiative, Sustainable Energy for All, which seeks to mobilise global action on three inter-linked objectives to be achieved by 2030: universal access to modern energy services, improved rates of energy efficiency, and expanded use of renewable energy sources

  2. Power marketing and renewable energy

    International Nuclear Information System (INIS)

    Fang, J.M.

    1997-01-01

    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

    1998-04-01

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

    2004-01-01

    The Dutch policy goal is to achieve a share of 17% renewable electricity in the domestic demand in 2020, corresponding to 18-24 TWh. It is uncertain whether and under which conditions this aim can be achieved. This paper aims to explore the feasible deployment of renewable electricity production in the Netherlands until 2020 by evaluating different images representing policies and societal preferences. Simultaneously, the most promising technologies for different settings are investigated and identified. First Dutch policy goals, governmental policy measures and definitions of renewable electricity are discussed. Second, a comparison is made of four existing studies that analyze the possible developments of renewable electricity production in the coming decades. Finally, three images are set up with emphasis on the different key factors that influence the maximum realizable potential. Results indicate onshore wind, offshore wind and large-scale biomass plants as most promising, robust options in terms of economical performance, ecological sustainability and high technical implementation rate. In the image with high implementation rates, an annual production of 42 TWh may be achieved in 2020, while under stringent economical or ecological criteria, about 25 TWh may be reached. When only the robust options are considered, 9-22 TWh can be realized. The analysis illustrates the importance of taking the different key factors mentioned influencing implementation into account. Doing so allows for identification of robust and less robust technological options under different conditions

    In the kidney of the gerbil in oliguria there exists a cortico-papillary gradient in the concentration of the sodium and of the urea; this gradient disappears in the gerbil kidney in osmotic diuresis or in the rat kidney in aqueous diuresis; in these three states of diuresis there is no significant difference in the potassium concentration between the surface and interior regions of the kidneys. Kinetic studies using tritiated water, urea {sup 14}C and {sup 24}Na show that water and urea in the interior regions of the kidney are only renewed very slowly (1 h) whereas the sodium is rapidly changed (1 mn). These results can be explained using WIRZ's theory concerning the mechanism of the counter-current concentration of urine. Furthermore, the evolution of the specific radioactivity of urea {sup 14}C is favorable for a cortical synthesis of urea. (author) [French] II existe dans le rein de Merions en oligurie un gradient cortico papillaire de la concentration du sodium et de l'uree; ce gradient est aboli dans le rein de Merions en diurese osmotique ou de rats en diurese aqueuse; dans ces 3 etats de diurese il n'y a pas de difference significative de la concentration du potassium entre les regions superficielles et profondes des reins. Des etudes cinetiques a l'aide d'eau tritiee, d'uree {sup 14}C et de {sup 24}Na montrent que l'eau et l'uree des regions profondes des reins ne sont renouveles que tres lentement (1 h), alors que le sodium est tres vite renouvele (1 mn). Ces resultats s'expliquent par la theorie de WIRZ sur le mecanisme de la concentration de l'urine par contre-courant. En outre, l'evolution renale de la radioactivite specifique de l'uree {sup 14}C est en faveur d'une synthese corticale de l'uree. (auteur)

In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. The Oregon Military Department (Military) acquired a large parcel of land located in south central Oregon. The land was previously owned by the US Air Force and developed for an Over-the-Horizon Backscatter Radar Transmitter Facility, located about 10 miles east of the town of Christmas Valley. The Military is investigating a number of uses for the site, including Research and Development (R&D) laboratory, emergency response, military operations, developing renewable energy and related educational programs. One of the key potential uses would be for a large scale solar photovoltaic power plant. This is an attractive use because the site has excellent solar exposure; an existing strong electrical interconnection to the power grid; and a secure location at a moderate cost per acre. The project objectives include: 1. Site evaluation 2. Research and Development (R&D) facility analysis 3. Utility interconnection studies and agreements 4. Additional on-site renewable energy resources analysis 5. Community education, outreach and mitigation 6. Renewable energy and emergency readiness training program for veterans

    Although the need to decarbonise our global economy and thus in particular the supply of energy to limit the global temperature increase is internationally undisputed the German politics in 2014 has significantly contributed less compared to previous years in order to attain this objective. The expansion of renewable energies in the electricity sector has decelerated significantly; and in the heating and mobility area no new impulses were set in relation to renewable energies. In addition, a dramatic fallen oil price makes it difficult to increase the use of renewable energy supply. Based on these deteriorated framework conditions compared to conditions of the previous years, the developments in Germany of 2014 are shown in the electricity, heat and transport sector in the field of renewable energy. For this purpose - in addition to a discussion of the current energy economic framework - for each option to use renewable energies the state and looming trends are analyzed. [German] Obwohl die Notwendigkeit zur Dekarbonisierung unserer globalen Wirtschaft und damit insbesondere der Energiebereitstellung zur Begrenzung des globalen Temperaturanstiegs international unstrittig ist, hat die deutsche Politik im Jahr 2014 im Vergleich zu den Vorjahren deutlich weniger zur Erreichung dieses Zieles beigetragen. Der Ausbau der Stromerzeugung aus erneuerbaren Energien im Stromsektor wurde deutlich verlangsamt; und im Waerme- und Mobilitaetsbereich wurden keine neuen Impulse in Bezug auf regenerative Energien gesetzt. Zusaetzlich erschwert ein drastisch gefallener Rohoelpreis die verstaerkte Nutzung des erneuerbaren Energieangebots. Ausgehend von diesen im Vergleich zu den Vorjahren verschlechterten Rahmenbedingungen werden nachfolgend die Entwicklungen in Deutschland des Jahres 2014 im Strom-, Waerme- und Transportsektor fuer den Bereich der erneuerbaren Energien aufgezeigt.

    1993-01-01

    Today, 111 nuclear power plants provide over 20 percent of the electrical energy generated in the United States. The operating license of the oldest operating plant will expire in 2003, one-third of the existing operating licenses will expire by 2010 and the newest plant's operating license will expire in 2033. The National Energy Strategy (NES) prepared by the Department of Energy (DOE) assumes that 70 percent of the current operating plants will continue to operate beyond their current license expiration. Power from current operating plants can assist in ensuring an adequate, diverse, and environmentally acceptable energy supply for economic growth and improved U.S. competitiveness. In order to preserve this energy resource, three major tasks must be successfully completed: (1) establishment of regulations, technical standards, and procedures for the preparation and review of License Renewal Applications (LRAs); (2) development of technical criteria and bases for monitoring, refurbishing or replacing plant equipment; and (3) demonstration of the regulatory process by a plant obtaining a renewed license. Since 1986, the DOE has been working with the nuclear industry and the Nuclear Regulatory Commission (NRC) to establish and demonstrate the option to extend the life of a nuclear power plant by renewing the operating license. The Monticello Lead Plant demonstration project was initiated in September 1988, following the Pilot Plant studies. This paper is primarily focused on the status and insights gained from the Northern States Power Company (NSP) Monticello Lead Plant demonstration project. The following information is included: (1) Current Status - Monticello License Renewal Application; (2) Economic Analysis; (3) License Renewal Regulatory Uncertainty Issues; (4) Key Decisions; (5) Management Structure; (6) Technical and Licensing Perspective; (7) NRC Interactions; (8) Summary

  16. Renewables for sustainable village power

    International Nuclear Information System (INIS)

    Flowers, L.

    1997-03-01

    It is estimated that two billion people live without electricity and its services. In addition, there is a sizeable number of rural villages that have limited electrical service, with either part-day operation by diesel gen-sets or partial electrification (local school or community center and several nearby houses). For many villages connected to the grid, power is often sporadically available and of poor quality. The U.S. National Renewable Energy Laboratory (NREL) in Golden, Colorado, has initiated a program to address these potential electricity opportunities in rural villages through the application of renewable energy (RE) technologies. The objective of this program is to develop and implement applications that demonstrate the technical performance, economic competitiveness, operational viability, and environmental benefits of renewable rural electric solutions, compared to the conventional options of line extension and isolated diesel mini-grids. These four attributes foster sustainability; therefore, the program is entitled Renewables for Sustainable Village Power (RSVP). The RSVP program is a multi-technology, multi-application program composed of six activities, including village applications development, computer model development, systems analysis, pilot project development, technical assistance, and Internet-based village power project data base. While the current program emphasizes wind, photovoltaics (PV), and their hybrids with diesel gen-sets, micro-hydro and micro-biomass technologies may be integrated in the future. NREL's RSVP team is currently involved in rural electricity projects in thirteen countries, with U.S., foreign, and internationally based agencies and institutions. The integration of the technology developments, institutional experiences, and the financial solutions for the implementation of renewables in the main line rural electrification processes in both the developing world and remote regions of the developed world is the goal

    Peu de notions scientifiques ont autant suscité l'imagination spéculative que l'entropie thermodynamique. Tous les systèmes organisés - les sociétés, les êtres vivants - seraient promis à la décadence, à la mort, forcément. Ce livre expose en toute clarté le développement historique et conceptuel de la thermodynamique. Née du désir de comprendre et de maîtriser le fonctionnement des machines à vapeur - emblème de nos sociétés industrielles -, elle est devenue la science des corps, de tous les corps à notre échelle. Mais elle se passait sans états d'âme de l'hypothèse atomique. Elle a donc été battue en brèche par la mécanique statistique qui faisait droit aux impératifs dictés par la structure atomique des corps. Après une lutte épique, et même sanglante, thermodynamique et mécanique statistique se sont réconciliées sur les fondements de la seconde mais avec les techniques de la première. Ce livre se lit comme un roman de physique contemporaine.

  18. Implicit LES using adaptive filtering

    Science.gov (United States)

    Sun, Guangrui; Domaradzki, Julian A.

    2018-04-01

    In implicit large eddy simulations (ILES) numerical dissipation prevents buildup of small scale energy in a manner similar to the explicit subgrid scale (SGS) models. If spectral methods are used the numerical dissipation is negligible but it can be introduced by applying a low-pass filter in the physical space, resulting in an effective ILES. In the present work we provide a comprehensive analysis of the numerical dissipation produced by different filtering operations in a turbulent channel flow simulated using a non-dissipative, pseudo-spectral Navier-Stokes solver. The amount of numerical dissipation imparted by filtering can be easily adjusted by changing how often a filter is applied. We show that when the additional numerical dissipation is close to the subgrid-scale (SGS) dissipation of an explicit LES the overall accuracy of ILES is also comparable, indicating that periodic filtering can replace explicit SGS models. A new method is proposed, which does not require any prior knowledge of a flow, to determine the filtering period adaptively. Once an optimal filtering period is found, the accuracy of ILES is significantly improved at low implementation complexity and computational cost. The method is general, performing well for different Reynolds numbers, grid resolutions, and filter shapes.

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

  20. Regulation - renewable energies finally liberated?

    International Nuclear Information System (INIS)

    Blosseville, Thomas

    2016-01-01

    Within the context defined by the new French policy for energy transition, notably in terms of share of renewable energies in final energy consumption, France seems to be somehow late in the development of these energies: about 1 GW of wind energy are installed each year when the expected pace would be 1,5 GW, and the photovoltaic market is shrinking. As the legal context is important, this article proposes an overview of the evolution of the French policy during the last four years which started with interesting measures. Recently, the government showed its will to liberate renewable energies from several constraints. Some legal procedures tend to slow down the development. Some advances could therefore be made, for example to make rules less complex and numerous. The different situations of the wind and biogas sectors are evoked, as well as new opportunities created by a new decree on investment planning

  1. Are renewable energies too expensive?

    International Nuclear Information System (INIS)

    2015-01-01

    As hydroelectricity is known to be profitable, and as biomass displayed good results when used for heating buildings, the issue of the cost of electricity produced by wind and photovoltaic energies is still a matter of debate. This article outlines how to take different factors into account to assess a discount rate. These factors are location which determines wind and sun resource, the future prices of fossil energies, rates of interest, and so on. It indicates that ground based wind and solar farms now have a kWh cost which is close to that of fossil energies, and lower than that of nuclear energy when taking investment and operation cost into account. The production cost of renewable energies has been dramatically reduced during the last years and this trend will probably continue during the years to come. Thus, the article states that a 100 per cent renewable mix seems possible for France by 2050 without significant over-costs

    Our current fossil-fuel-based system is causing potentially catastrophic changes to our planet. The quest for renewable, nonpolluting sources of energy requires us to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels. Light-source facilities - the synchrotrons of today and the next-generation light sources of tomorrow - are the scientific tools of choice for exploring the electronic and atomic structure of matter. As such, these photon-science facilities are uniquely positioned to jump-start a global revolution in renewable and carbonneutral energy technologies. In these pages, we outline and illustrate through examples from our nation's light sources possible scientific directions for addressing these profound yet urgent challenges.

    India has done a significant progress in the power generation in the country. The installed generation capacity was 1300 megawatt (MW) at the time of Independence i.e. about 60 years back. The total generating capacity anticipated at the end of the Tenth Plan on 31-03-2007, is 1, 44,520 MW which includes the generation through various sectors like Hydro, Thermal and Nuclear. Emphasis is given to the renewable energy programme towards gradual commercialization. This programme is looked after by the Ministry of Non-Conventional Sources of energy. Since the availability of fossil fuel is on the decline therefore, in this backdrop the norms for conventional or renewable sources of energy (RSE) is given importance not only in India but has attracted the global attention. The main items under RSE are as follows: (i) Hydro Power (ii) Solar Power (iii) Wind Power (iv) Bio-mass Power (v) Energy from waste (vi) Ocean energy, and (vii) Alternative fuel for surface transportation. Evolution of power transformer technology in the country during the past five decades is quite impressive. There are manufacturers in the country with full access to the latest technology at the global level. Some of the manufacturers have impressive R&D set up to support the technology. Renewable energy is very much promoted by the Chinese Government. At the same time as the law was passed, the Chinese Government set a target for renewable energy to contribute 10% of the country's gross energy consumption by 2020, a huge increase from the current 1%. It has been felt that there is rising demand for energy, food and raw materials by a population of 2.5 billion Chinese and Indians. Both these countries have large coal dominated energy systems in the world and the use of fossil fuels such as coal and oil releases carbon dioxide (CO2) into the air which adds to the greenhouse gases which lead to global warming.

    Résumé Objectif Présenter des recommandations sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes. Qualité des données Les recommandations thérapeutiques des lignes directrices canadiennes sur les infections transmissibles sexuellement reposent sur une recherche documentaire de même que sur des catégories de recommandations et des niveaux de qualité de données déterminés par au moins 2 évaluateurs. Les recommandations ont été revues par des pairs et sont en instance d’approbation par le groupe de travail d’experts. Message principal Les nouvelles recommandations portant sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes préconisent les cultures à titre d’outil diagnostique lorsqu’elles sont pratiques, le traitement par antibiothérapie combinée (ceftriaxone associée à l’azithromycine) et le signalement sans délai de tous les cas dont le traitement a échoué aux autorités de santé publique. Conclusion Si elles sont suivies, ces nouvelles recommandations pourraient réduire l’échec thérapeutique, contribuer à une surveillance plus étroite des tendances à la résistance de Neisseria gonorrhoeae aux antibiotiques et contribuer à prévenir la transmission de gonorrhée résistante à plusieurs médicaments.

    2012-04-01

    Full Text Available L’essai propose de suivre le fil des débats autour de l’Immaculée Conception dans les pays germaniques à partir du Concile de Bâle jusqu’au début du xvie siècle.Le décret du Concile en faveur de cette doctrine (1439 avait ranimé un désaccord déjà ancien entre les ordres mendiants et particulièrement entre les Franciscains et les Dominicains au sujet de la Vierge immaculée. Les deux traités défendant ce privilège (1444/1445 écrits par l’ancien évêque de Constance, Otto d’Hachberg, sont un premier témoignage de ce conflit en Allemagne. Dès l’avènement du pape franciscain Sixte IV (1471-1484, les disputations publiques et les polémiques littéraires au sujet de l’Immaculée Conception se multiplient. Le point culminant de cette controverse arrive au moment du procès contre le dominicain Wigand Wirt à Rome où l’accusé se voit contraint en 1512 de révoquer ses écrits diffamatoires. L’isolement croissant de l’ordre dominicain dans ce débat semble être aussi la conséquence du thomisme rigide des dominicains observants en Italie et en Allemagne. Ainsi les frères observants de la province de « Teutonie » suivent-ils de près l’opinion de leur confrère Vincent Bandelli de la congrégation observante de Lombardie, déclarant la foi en l’Immaculée Conception comme hérétique. Bien que la bulle Grave nimis (1482 interdise aux partis opposés de se dénoncer mutuellement comme hérétiques, les observants allemands ne manquent pas de faire usage de cette arme, ce qui provoque l’alliance de leurs adversaires (Carmes, Chartreux, Augustiniens, Bénédictins et cercles humanistes de toute couleur dans le camp des franciscains de l’Observance. L’analyse des traités et des circonstances de cette querelle met donc en lumière les tensions et les constellations intellectuelles du discours religieux dans les décennies avant la Réforme protestante où le raisonnement théologique fait place

  1. Photographie pittoresque. L’influence des modèles esthétiques traditionnels sur les photographies de la pauvreté

    2009-12-01

    Full Text Available Partant d’un constat, la difficulté de retrouver des reportages sur la pauvreté dans les collections françaises de photographies, l’article se propose de démontrer l’existence d’un autre modèle esthétique déterminant. En effet, longtemps construites à partir des modèles des Beaux-arts et du théâtre, une partie des photographies conservées du XIXe siècle est fondée sur un principe de mise en scène apparu dès les années 1850. Dans les cas des tableaux vivants, portraits et scènes de genre photographiques, les sujets sont le plus souvent puisés dans la tradition picturale, effectivement prétexte aux figures de pauvreté. Il paraissait donc intéressant de reporter la question lorsque la photographie dite « instantanée » est mise au point, à la fin du XIXe siècle, et renouvelle en profondeur les formes de l’image. On constate que si cette dernière offre l’accès très attendu à l’enregistrement direct de la réalité, elle ne fait pour autant pas disparaître la pratique, devenue traditionnelle, des mises en scène. Au contraire, celles-ci sont désormais enregistrées en pleine rue, en pleine action (petits métiers, mendiants, bohémiens et ainsi rendues plausibles grâce à un effet de « scène prise sur le vif ». Oscillant entre reportage et pittoresque, cette pratique singulière de l’instantané offre incontestablement un univers visuel original. Mais, les mêmes images investissent dans le même temps plus silencieusement les dictionnaires, revues, ouvrages scolaires, etc. Privées de leur contexte de production, elles y sont présentées avec succès comme images de documentation. Ce paradoxe amène à soulever certaines interrogations quant aux relations, plus ou moins délibérées, entretenues jusqu’à aujourd’hui par la photographie documentaire avec les canons pittoresques.Since it is very difficult to find reports on poverty in the French collections of photographs, the article

  2. LES of Gas Exchange in IC Engines

    2013-10-01

    Full Text Available As engine technologies become increasingly complex and engines are driven to new operating points, understanding transient phenomena is important to ensure reliable engine operation. Unlike Reynolds Averaged Navier-Stokes (RANS studies that only provide cycle-averaged information, Large Eddy Simulation (LES studies are capable of simulating cycle-to-cycle dynamics. In this work, a finite difference based structured methodology for LES of IC engines is presented. This structured approach allows for an efficient mesh generation process and provides potential for higher order numerical accuracy. An efficient parallel scalable block decomposition is done to overcome the challenges associated with the low ratio of fluid elements to overall mesh elements. The motion of the valves and piston is handled using a dynamic cell blanking approach and the Arbitrary Lagrangian Eulerian (ALE method, respectively. Modified three-dimensional Navier-Stokes Characteristic Boundary Conditions (NSCBC are used in the simulation to prescribe conditions in the manifolds. The accuracy of the simulation framework is validated using various canonical configurations. Flow bench simulations of an axisymmetric configuration and an actual engine geometry are done with the LES methodology. Simulations of the gas exchange in an engine under motored conditions are also performed. Overall, good agreement is obtained with experiments for all the cases. Therefore, this framework can be used for LES of engine simulations. In the future, reactive LES simulations will be performed using this framework.

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. With Ireland's current 'trajectory' of renewable energy growth, it is likely to slightly fall short of its 2020 nationally binding renewable energy target. Ireland initiated a 'moratorium' on its REFIT (Renewable Energy Feed-in Tariff) support scheme in December 2015, with the aim of introducing a revised scheme in 2017 in line with market developments. Grants and tax relief remain in place for renewable heat promotion. An Offshore Renewable Energy Development Plan (OREDP) was introduced in 2014, which sets out Government policy in relation to the sustainable development of Ireland's abundant offshore renewable energy resource

    2011-10-06

    This project examines renewable energy deployment in the United States using a version of the GCAM integrated assessment model with detailed a representation of renewables, the GCAM-RE. Electricity generation was modeled in four generation segments and 12-subregions. This level of regional and sectoral detail allows a more explicit representation of renewable energy generation. Wind, solar thermal power, and central solar PV plants are implemented in explicit resource classes with new intermittency parameterizations appropriate for each technology. A scenario analysis examines a range of assumptions for technology characteristics, climate policy, and long-distance transmission. We find that renewable generation levels grow over the century in all scenarios. As expected, renewable generation increases with lower renewable technology costs, more stringent climate policy, and if alternative low-carbon technology are not available. The availability of long distance transmission lowers policy costs and changes the renewable generation mix.

    The Global Utilities arm of international business consultants PriceWaterhouseCoopers (PWC) has provided a unique insight into the investment plans of Australian utilities regarding renewable energy. PWC has released the findings of a survey of electricity generators and retailers that neatly illustrates the risks and opportunities facing corporations liable under the mandatory renewable energy targets (MRET). Probably the most revealing finding of the PWC report- 'The Future of Australian Renewable Energy' was that the majority of respondents have not yet formulated a comprehensive renewable energy strategy aimed at meeting their obligations under MRET, or maximising the benefit of renewable energy certificates (RECs) produced. Notably, the majority of those surveyed believed that the strongest incentives for investing in new renewable energy generation was the company's 'green image'. In contrast investment characteristics such as low risk returns, the achievement of cost efficiencies or attractive revenue streams were not critical reasons for investing in renewable generation

    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.

    The thesis presents various possibilities for renewable energy in Norway. The wind power would give a practical and economic alternative. The external costs for the wind power would be moderate. In chapter 3 the utility cost analysis for renewable alternatives are studied relative to the macroeconomic efficiency. Some methodical problems and how these analyses are used are reviewed. In the practical utility cost analyses wind power is studied relative to gas power which is the non-renewable alternative present in Norway today. A qualitative part is included. It is not possible to determine whether wind power is preferable to gas power in the macroeconomic perspective. Wind power would be the choice if high environmental and CO2 cleaning costs are expected. The first conclusion to be drawn is that it is difficult to decide whether wind power is the best solution based on cost benefit analysis. However, the alternative seems to be quite robust in the analysis. Due to the central position the energy supplies have in the society this business should be heavily regulated. The sector is also overtaxed as a reduction in consumption is desired. The analysis shows that the system does not function perfectly. The thesis surveys various measures for improving the renewable energy supply and focuses on the wind power. A model for and analysis of the measures are carried out and resulted in a second conclusion. The measures have various properties as to the influence on the market. A subsidy is a fine measure for stimulation production of green power while a tax reduces efficiently the production of black power. A system with green licenses in combination with a subsidy and a tax would be preferable as to increasing the part of renewable energy of the total production. It is therefore necessary to have clearly defined goals and use suitable measures for achieving them. The costs of wind power is falling and it would therefore soon be macroeconomic profitable. It is also

    Dozier, J.; Lee, S.; Kuo, P.T.

    2001-01-01

    The staff of the NRC has been developing three regulatory guidance documents for license renewal: the Generic Aging Lessons Learned (GALL) report, Standard Review Plan for License Renewal (SRP-LR), and Regulatory Guide (RG) for Standard Format and Content for Applications to Renew Nuclear Power Plant Operating Licenses. These documents are designed to streamline the license renewal review process by providing clear guidance for license renewal applicants and the NRC staff in preparing and reviewing license renewal applications. The GALL report systematically catalogs aging effects on structures and components; identifies the relevant existing plant programs; and evaluates the existing programs against the attributes considered necessary for an aging management program to be acceptable for license renewal. The GALL report also provides guidance for the augmentation of existing plant programs for license renewal. The revised SRP-LR allows an applicant to reference the GALL report to preclude further NRC staff evaluation if the plant's existing programs meet the criteria described in the GALL report. During the review process, the NRC staff will focus primarily on existing programs that should be augmented or new programs developed specifically for license renewal. The Regulatory Guide is expected to endorse the Nuclear Energy Institute (NEI) guideline, NEI 95-10, Revision 2, entitled 'Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule', which provides guidance for preparing a license renewal application. This paper will provide an introduction to the GALL report, SRP-LR, Regulatory Guide, and NEI 95-10 to show how these documents are interrelated and how they will be used to streamline the license renewal review process. This topic will be of interest to domestic power utilities considering license renewal and international ICONE participants seeking state-of-the-art information about license renewal in the United States

    Australia is committed to an 8 per cent reduction in its emissions of greenhouse gases above 1990 levels as a result of the Kyoto Protocol for the period 2008-2012. At present, the emissions stand at 17.4 per cent above 1990 levels. Total electrical power in Australia resulting from renewable energy is in the order of 10.5 per cent. A mandatory renewable energy target of 9500 gigawatt hour (GWh) of extra renewable energy is to be produced annually by 2010, under the Renewable Energy (Electricity) Act. An emissions trading system has been implemented, involving one renewable energy certificate (REC) created for each megawatt hour of renewable energy generated. A significant expansion of the demand for renewable energy is expected in Australia over the next ten years, according to the Australian Greenhouse Office. Increased opportunities for local and international firms operating in the field of renewable energy are being created by the Australian government through initiatives such as the Renewable Energy Commercialization Program, and the Renewable Remote Power Generation Program. Solar, biomass, and wind power are comprised in the wealth of renewable energy resources in Australia. The market remains largely undeveloped. Firms from the United States and the European Union are the leading exporters of renewable energy technology to Australia. Public utilities and independent power producers having entered the deregulated electricity market are the consumers of renewable energy technology and services. A country with minimal duties in most cases, Australia has much in common with Canada, including similar regulatory and legal systems. Australia applies a 10 per cent goods and services tax, which would apply to Canadian exports. It was advised to consult the Australian Customs Service for additional information concerning duties that might be applicable to the renewable energy industry. 28 refs., 3 tabs

    The solar energy manifests itself in different forms and its application has been fundamental for the humankind development. These forms are known as renewable energies, since they are energy forms that are renewed or remade with time or that are so abundant on Earth, that they will last for hundreds or thousands of years, either we use them or not. The main advantage of the utilization of the renewable energies in comparison with hydrocarbons is the one of having smaller impact on the environment, which brings about the conservation of nonrenewable resources, and to postpone its exhaustion. They allow the distributed generation, diminishing the power losses in the transmission and distribution systems, which increases the overall efficiency. In addition they can be the drive for regional development and generation of employment, because when having applications in remote zones and being a field still not completely developed in Mexico, the possibility exists of enabling professionals and technicians. From the point of view of the power sector, the renewable energies extend the supply and availability of energy, making more flexible and independent the operation and reliability of the national power system. [Spanish] La energia solar se manifiesta de diversas formas y su aplicacion ha sido fundamental para el desarrollo de la humanidad.

    Russia is rich not only in oil, gas and coal, but also in wind, hydro, geothermal, biomass and solar energy - the resources of renewable energy. However, fossil fuels dominate Russia's current energy mix, while its abundant and diverse renewable energy resources play little role. What are the near- and medium-term opportunities for renewables in Russia? What preconditions are necessary to draw renewables into the energy mix to complement Russia's other ample energy resources? Russia's renewables can cost-effectively provide energy services where conventional forms are expensive. Whether it is geothermal resources in the Far East or North Caucasus, bio-energy resources from the vast territories, or hydro from the many watersheds, established renewable technologies can cost effectively supplement energy from fossil fuels. At the same time, new renewables such as wind and solar energy can serve remote populations and in the right circumstances, provide energy at competitive prices on the grid. This report demonstrates that renewable energy can offer a real means to address some of Russia's energy and economic challenges. It identifies the first steps toward creating a Russian renewables market and will contribute to a better understanding by both Russian and international industry, of the potential for profitable renewables projects, and the incentive to start undertake them.

    Approximately 7 per cent of Prince Edward Island's (PEI) energy supply is from renewable sources, acquired mainly from biomass. Wind power accounts for 0.5 per cent of electricity production. This paper discussed issues concerning renewable energy developments in PEI, with particular reference to the PEI Renewable Energy Act as well as the PEI energy framework and renewable energy strategy, which was the result of public consultation sessions held in 2003. The results of these sessions indicated that greater development of indigenous renewable energy resources was desired, particularly in wind power. It was also stated that the government should help to advance renewable energy development in the province. Several development opportunities were highlighted, including: wind; biodiesel; ethanol; biomass; bio-gas; and small-scale hydro. The advantages of wind power were reviewed and wind data was presented. The economic and community benefits of renewable energy include local price stability, development opportunities, diversity of fuel type and security of supply. It was noted that renewable energy fully complemented the energy goals of the PEI government. Several strategies were discussed towards the development of renewable energy, including feasibility studies in biogas and biomass generation. The PEI government's commitment towards developing a regulatory framework acknowledging environmental sustainability was re-stated. Objectives include the promotion of renewable energy sources through the establishment of a Renewable Portfolio Standard for electricity; improvements in the economics of small-scale electricity production from renewable resources through the introduction of net metering; decreases in peak demand; enablement of green credits; the designation of areas for large-scale wind developments; and provision of guaranteed prices paid to producers for medium and large-scale renewable energy generators through feed-in tariffs. tabs, figs

  13. Radiobiology of Cell Renewal Systems

    In recent years, considerable attention has been given to quantitative aspects of radiation effects on cell renewal systems. The behaviour of stem-type cells has been a focal point of interest, and it has been assumed by many that the fraction of surviving stem cells is the principal determinant of the probability of survival of the irradiated system or organism. The apparent close similarity in dose requirements for impairment of reproductive capacity, and the similarity in early repair and in stage sensitivity in vitro and in vivo.clearly indicate that purely cellular phenomena are reflected in the organized population. It does not necessarily follow, however, that there is a straightforward relationship between radiation effects on stem cells and the response of systems or organisms. Indeed, this is not so. It is abundantly clear that differential radiosensitivity is anchored in a number of variables that are associated with the organizational framework of the system and its environment. Many, but not all, effects can be understood in terms of the normal kinetics of the developmental pathway. Yet, deviations from normal kinetics that are minor in the steady state can have profound significance in the perturbed state. To understand the radiobiology of cell renewal systems and to place the many possible variables in reasonable perspective, we need to know a good deal more about the interplay of the component parts than we do at present. When we view the totality of an organized cell population, it seems necessary to postulate mechanisms external to any given cell in the regulation of the balanced sequence of proliferation and differentiation. At present, we have only a vague idea about this. Most attention has been directed to the proliferative process and it is encouraging to note the growing interest in the more developmental facets of cell renewal. (author)

    Full Text Available L’article s’interroge sur les modifications que la prise en compte du phénomène de la globalisation entraîne dans le processus d’individuation, en mettant au cœur de l’analyse la diffraction des phénomènes sociaux. C’est la complexité de cette diffraction qui rend compte, à tous les niveaux, de la dynamique entre le global et le local (que ce soit au niveau de la régulation du capitalisme ou des positions sociales occupées par les acteurs. Pour ce faire, l’article mobilise la notion d’épreuve comme opérateur analytique le plus apte à permettre une nouvelle mise en relation entre la structure de la société et les expériences des individus. Elle ouvre ainsi d’autres perspectives pour la sociologie comparée.In the light of social diffraction, globalisation can be seen as impacting on individuation. The complexity of this diffraction clarifies the dynamic relationship between the local and the global at all levels (including the regulation of capitalism and the social positions occupied by diverse actors. “Putting to the proof” provides an analytical framework for a fresh look at social structure and individual experience, thus contributing to a renewal of comparative sociology.

    Renewable resources are used increasingly in the production of polymers. In particular, monomers such as carbon dioxide, terpenes, vegetable oils and carbohydrates can be used as feedstocks for the manufacture of a variety of sustainable materials and products, including elastomers, plastics, hydrogels, flexible electronics, resins, engineering polymers and composites. Efficient catalysis is required to produce monomers, to facilitate selective polymerizations and to enable recycling or upcycling of waste materials. There are opportunities to use such sustainable polymers in both high-value areas and in basic applications such as packaging. Life-cycle assessment can be used to quantify the environmental benefits of sustainable polymers.

    This paper is intended to provide general advice to sponsors of renewable energy projects who expect to raise project-based financing from commercial banks to fund the development of their projects. It sets out, for the benefit of such sponsors, how bankers typically approach the analysis of these undertakings and in particular the risk areas on which they concentrate. By doing so it should assist sponsors to maximize their prospects of raising bank finance. The watchword for sponsors approaching banks must be ''Be Prepared'' . (author)

  18. Renewable Energy Resources in Lebanon

    The energy sector in Lebanon plays an important role in the overall development of the country, especially that it suffers from many serious problems. The fact that Lebanon is among the few countries that are not endowed with fossil fuels in the Middle East made this sector cause one third of the national debt in Lebanon. Despite the large government investments in the power sector, demand still exceeds supply and Lebanon frequently goes through black out in peak demand times or has to resort to importing electricity from Syria. The Energy production sector has dramatic environmental and economical impacts in the form of emitted gasses and environment sabotage, accordingly, it is imperative that renewable energy (RE) be looked at as an alternative energy source. Officials at the Ministry of Energy and Water (MEW) and Lebanese Electricity (EDL) have repeatedly expressed their support to renewable energy utilization. So far, only very few renewable energy applications can be observed over the country. Major efforts are still needed to overcome this situation and promote the use of renewable energy. These efforts are the shared responsibility of the government, EDL, NGO's and educational and research centers. Additionally, some efforts are being made by some international organizations such as UNDP, ESCWA, EC and other donor agencies operating in Lebanon. This work reviews the status of Energy in Lebanon, the installed RE projects, and the potential projects. It also reviews the stakeholders in the field of RE in Lebanon Conclusion In considering the best R.E. alternative, it is important to consider all potential R.E. sources, their costs, market availability, suitability for the selected location, significance of the energy produced and return on investment. Several RE resources in Lebanon have been investigated; Tides and waves energy is limited and not suitable two tentative sites for geothermal energy are available but not used. Biomass resources badly affect the
