Book Synopsis Contribution a l'estimation des ressources énergétiques solaires by : Jean-François Tricaud
Download or read book Contribution a l'estimation des ressources énergétiques solaires written by Jean-François Tricaud and published by . This book was released on 1976 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le but de ce travail est de fournir aux utilisateurs existants ou potentiels une estimation (à partir des données existantes) des ressources énergétiques solaires en France : rayonnement direct et rayonnements diffus et global reçus par des plans diversement orientés et inclinés. Ces estimations sont également utilisables dans le calcul du bilan thermique des habitations dont le chauffage est assuré par l’une des énergies traditionnelles. Cette étude comprend deux parties. Dans la première partie, après avoir répertorié les données disponibles, sont exposées les méthodes d'estimation : des rayonnements Global et Diffus reçus par le plan horizontal. Du rayonnement Direct (incidence normale) Des rayonnements Global et Diffus reçus par des plans diversement orientés et inclinés. Nota : Alors que les estimations des rayonnements global et diffus sont \faites pour l'ensemble du territoire celle du rayonnement Direct est uniquement proposée pour la zone méditerranéenne qui est la seule (excepté peut être un secteur entourant La Rochelle) à présenter en France un potentiel réel pour les applications de la concentration du rayonnement solaire. Dans la deuxième partie, un atlas des ressources énergétiques solaires en France est ébauché en vue des applications de la concentration du rayonnement solaire d'une part et des insolateurs plans diversement orientés et inclinés d'autre part.
Book Synopsis De la source à la ressource by : Antoine Fontaine
Download or read book De la source à la ressource written by Antoine Fontaine and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette recherche s'intéresse à la construction des ressources énergétiques renouvelables et, chemin faisant, à celle de la soutenabilité de la transition énergétique dans la filiation des travaux de la nouvelle géographie des ressource (Bridge, Castree). La thèse défendue est que la ressource énergétique émerge d'un ensemble de relations construites entre une source d'énergie et une perspective de valeur qui lui est progressivement associée. Ainsi, les qualités de la ressource énergétique ne sont pas données par les caractéristiques physiques de la source d'énergie (e.g. le rayonnement solaire abondant et diffus) mais par les relations (matérielles, sociales et spatiales) qui se tissent autour de cette source pour l'associer à des matérialités (e.g. le réseau électrique, la toiture, le paysage) dans une perspective de valorisation. En cela, la soutenabilité des énergies renouvelables est présentée comme une qualité relationnelle qui émerge en même temps que se structure le « milieu associé » (Simondon) de projets photovoltaïques.La thèse s'organise autour d'une enquête sur l'émergence de projets photovoltaïques coopératifs (i.e. les centrales villageoises), en région Rhône Alpes, qui proposent de construire la ressource solaire de manière collective et multidimensionnelle (e.g. paysage, partage de valeur), dans le contexte du début des années 2010. L'enquête montre que ces projets se nourrissent des héritages (e.g. des réseaux d'acteurs, de compétences, de visions politiques) d'un ensemble de projets énergétiques pionniers développés en Rhône-Alpes des années 1970 aux années 1990, héritages grâce auxquels ces collectifs apprennent à composer avec une politique nationale du photovoltaïque qui leur est peu favorable. Leur contribution à la construction de ressources solaires soutenables repose sur la capacité de ces collectifs à constamment s'adapter pour dépasser les épreuves qu'ils rencontrent.
Book Synopsis Energy Transitions by : Olivier Labussière
Download or read book Energy Transitions written by Olivier Labussière and published by Springer. This book was released on 2018-04-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elucidates what it means to transition to alternative sources of energy and discusses the potential for this energy transition to be a more democratic process. The book dynamically describes a recent sociotechnical study of a number of energy transitions occurring in several countries - France, Germany and Tunisia, and involving different energy technologies - including solar, on/off-shore wind, smart grids, biomass, low-energy buildings, and carbon capture and storage. Drawing on a pragmatist tradition of social inquiry, the authors examine the consequences of energy transition processes for the actors and entities that are affected by them, as well as the spaces for political participation they offer. This critical inquiry is organised according to foundational categories that have defined the energy transition - ‘renewable’ energy resources, markets, economic instruments, technological demonstration, spatiality (‘scale’) and temporality (‘horizon(s)’). Using a set of select case studies, this book systematically investigates the role these categories play in the current developments in energy transitions.
Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Book Synopsis The Mediterranean region under climate change by : Collectif
Download or read book The Mediterranean region under climate change written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Synopsis Risk Management and Food Safety by : Food and Agriculture Organization of the United Nations
Download or read book Risk Management and Food Safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 1997 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk analysis is widely recognised as the fundamental methodology underlying the development of food safety standards. As recognised in the 1995 consultation, risk analysis is composed of three separate but integrated elements, namely risk assessment, risk management and risk communication. That consultation recognised risk communication as an interactive process of exchange of information and opinion on risk among risk assessors, risk managers, and other interested parties. Risk management is defined within Codex as the process of weighing policy alternatives in the light of the results of risk assessment and, if required, selecting and implementing appropriate control options, including regulatory measures. The outcome of the risk management process, as undertaken by Committees within the Codex Alimentarius system, is the development of standards, guidelines and other recommendations for food safety, m the national situation it is likely that different risk management decisions could be made according to different criteria and different ranges of risk management options. The overall objective of Codex is to ensure consumer protection and to facilitate international trade.
