Download or read book El universo de las energ as renovables written by Tomás Perales Benito and published by Marcombo. This book was released on 2013 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Las energías renovables involucran a un elevado número de actores. A diferencia de los procedimientos energéticos tradicionales movidos por su propia inercia, los derivados directa o indirectamente del Sol demandan promoción social y formación en muy diferentes niveles con anterioridad a las acciones específicas: la búsqueda de emplazamientos, la instalación, la explotación y el mantenimiento. Este libro, con título tan elevado, se ha gestado para presentar todos los procedimientos de condición renovable actuales a los interesados en conocer sus fundamentos tecnológicos, sus aplicaciones y sus repercusiones medioambientales. No invade competencias de los proyectistas e instaladores, para los que existen otros textos. En él se describen, con el nivel adecuado a quienes deben moverse sobre todo su mundo científico, técnico y social, los procedimientos fotovoltaico y eólico; los térmicos e hidráulicos en todas sus formas; el del hidrógeno, la biomasa y los biocombustibles. Como complemento agrega diversos anexos con datos acerca de las unidades de medida y páginas web de las instituciones nacionales e internacionales en las que se puede recabar más información. Tomás Perales Benito viene simultaneando desde hace más de 30 años la docencia y la literatura. Ha escrito 25 libros dedicados a temas de divulgación tecnológica, como las energías renovables, uno al estraperlo que se produjo en el periodo histórico de la posguerra y cientos de artículos de opinión y crítica. Ha cultivado también el cuento tradicional. Cuenta con el premio de relato corto Félix Grande.

This book was released on 2016-11-20 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: El nuevo ecosistema audiovisual, en el que las televisiones tratan de convivir con Internet, ofrece grandes posibilidades para informar, sensibilizar y educar al público sobre los retos ambientales a los que se enfrenta nuestra sociedad. Sin embargo, la investigación pone de manifiesto que los medios no han estado a la altura del envite, debido a la complejidad de las cuestiones ambientales, la siempre difícil relación de la ciencia con los medios de comunicación y la creciente tendencia hacia el infoentretenimiento. El medio ambiente en el nuevo universo audiovisual es el resultado tangible de un rico debate generado en la octava edición del foro «Transformar la televisión», reunido en La Casa Encendida, centro social y cultural de Fundación Montemadrid. En las páginas de este volumen, una decena de expertos en la materia analizan, con rigor y valentía, la representación audiovisual del medio ambiente en este nuevo paradigma comunicativo, en el que los formatos televisivos tradicionales han perdido peso y el vídeo en línea ha alcanzado un notable desarrollo, impulsado por las redes sociales.
Download or read book The Low Carbon Contradiction written by Gustav Cederlof and published by Univ of California Press. This book was released on 2023 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the pursuit of socialism, Cuba became Latin America's most oil dependent economy. When the Soviet Union collapsed, the country lost 86 percent of its crude oil supplies, resulting in a severe energy crisis. In the face of this shock, Cuba started to develop a low-carbon economy on the basis of economic and social reform rather than high-tech innovation. The Low Carbon Contradiction examines this period of rapid low-carbon energy transition, which many have described as a "Cuban miracle" or even a real-life case of successful "degrowth". Based on original research inside households and workplaces, universities and government offices, Gustav Cederlöf retells the history of the Cuban Revolution as one of profound environmental and infrastructural change. In doing so, he opens up new questions about energy transitions, their politics, and the conditions of a socially just low-carbon future. The Cuban experience shows how a society can transform itself while rapidly cutting carbon emissions in the search for sustainability"--

Download or read book The Conservation Atlas of Tropical Forests written by Caroline Harcourt and published by Macmillan Reference USA. This book was released on 1996 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final volume in the The Conservation Atlas of Tropical Forests covers the Americas. It provides an up-to-date overview of the status of rain forests in South America, Central America, and the Caribbean. Following the format of the two previous volumes The Conservation Atlas of Tropical Forests: Asia and the Pacific (1991) and The Conservation Atlas of Tropical Forests: Africa (1992), the atlas is divided into two parts. Part I introduces and discusses the complex interrelated issues in the regions that are involved in both deforestation as well as conservation of the tropical forests. Included are discussions on the history of the forests, agricultural colonization policies and deforestation, conservation polices for plants and wildlife, protected areas, and the future of the tropical forests. Part II is a detailed and well referenced country-by-country analysis of conservation status and trends. Four-colour maps have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies.

Download or read book Spain s Photovoltaic Revolution written by Pedro A. Prieto and published by Springer Science & Business Media. This book was released on 2013-01-04 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Energy Return on Energy Invested (EROI or EROEI) is the amount of energy acquired from a particular energy source divided by the energy expended, or invested, in obtaining that energy. EROI is an essential and seemingly simple measure of the usable energy or “energy profit” from the exploitation of an energy source, but it is not so easy to determine all of the energy expenditures that should be included in the calculation. Because EROI values are generally low for renewable energy sources, differences in these estimates can lead to sharply divergent conclusions about the viability of these energy technologies. This book presents the first complete energy analysis of a large-scale, real-world deployment of photovoltaic (PV) collection systems representing 3.5 GW of installed, grid-connected solar plants in Spain. The analysis includes all of the factors that limit and adjust the real electricity output through one full-year cycle, and all of the fossil fuel inputs required to achieve these results. The authors’ comprehensive analysis of energy inputs, which assigns energy cost estimates to all financial expenditures, yields EROI values that are less than half of those claimed by other investigators and by the solar industry. Sensitivity analysis is used to test various assumptions in deriving these EROI estimates. The results imply that the EROI of current, large-scale PV systems may be too low to seamlessly support an energy and economic transition away from fossil fuels. Given the pervasiveness of fossil fuel subsidies in the modern economy, a key conclusion is that all components of the system that brings solar power to the consumer, from manufacturing to product maintenance and life cycle, must be improved in terms of energy efficiency. The materials science of solar conversion efficiency is only one such component. Sunny Spain represented an ideal case study as the country had the highest penetration of solar PV energy at 2.3 percent of total national demand as well as state-of-the-art expertise in solar power including grid management of intermittent, modern renewable systems. This book, written by a uniquely qualified author team consisting of the chief engineer for several major photovoltaic projects in Spain and the world’s leading expert on the concept and application of EROI, provides a comprehensive understanding of the net energy available to society from energy sources in general and from functioning PV installations under real-world conditions in particular. The authors provide critical insight into the capacity of renewable energy sources to fill the foreseeable gap between world energy demand and depletion rates for fossil fuels. · Presents the first comprehensive study of the EROI of large-scale solar PV systems in a developed country · Uses real-world operational data rather than laboratory approximations and extrapolations · Describes the dependence of one alternative energy source on the goods and services of a fossil-fueled economy · Has global implications for the potential of renewable energy sources to replace dwindling reserves of fossil fuels · Written with the first-hand knowledge of the chief, on-site engineer for many solar installations in Spain together with the leader in the development and application of the concept of EROI

This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Available in PDF, EPUB and Kindle. Book excerpt: This inquiry into the technical advances that shaped the 20th century follows the evolutions of all the principal innovations introduced before 1913 (as detailed in the first volume) as well as the origins and elaborations of all fundamental 20th century advances. The history of the 20th century is rooted in amazing technical advances of 1871-1913, but the century differs so remarkably from the preceding 100 years because of several unprecedented combinations. The 20th century had followed on the path defined during the half century preceding the beginning of World War I, but it has traveled along that path at a very different pace, with different ambitions and intents. The new century's developments elevated both the magnitudes of output and the spatial distribution of mass industrial production and to new and, in many ways, virtually incomparable levels. Twentieth century science and engineering conquered and perfected a number of fundamental challenges which remained unresolved before 1913, and which to many critics appeared insoluble. This book is organized in topical chapters dealing with electricity, engines, materials and syntheses, and information techniques. It concludes with an extended examination of contradictory consequences of our admirable technical progress by confronting the accomplishments and perils of systems that brought liberating simplicity as well as overwhelming complexity, that created unprecedented affluence and equally unprecedented economic gaps, that greatly increased both our security and fears as well as our understanding and ignorance, and that provided the means for greater protection of the biosphere while concurrently undermining some of the key biophysical foundations of life on Earth. Transforming the Twentieth Century will offer a wide-ranging interdisciplinary appreciation of the undeniable technical foundations of the modern world as well as a multitude of welcome and worrisome consequences of these developments. It will combine scientific rigor with accessible writing, thoroughly illustrated by a large number of appropriate images that will include historical photographs and revealing charts of long-term trends.
