Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book Northern Prairie Wetlands written by Arnoud van der Valk and published by Wiley-Blackwell. This book was released on 1989 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The northern prairie region includes the prairie pothole region and the Nebraska sandhills. The first chapter deals with the social and economic conditions in the prairie pothole region and their impacts on the perception that farmers, business executive, and politicians in the region have of its wetland. The next three chapters deal with hydrology and water chemistry. They describe the physical and chemical environment of northern prairie wetlands. The flora and fauna are covered in seven chapters. An overview of the ecology of the wetlands of the Nebraska sandhills is provided in the last chapter.

Download or read book Global Outlook for Ice Snow written by Pål Prestrud and published by UNEP/Earthprint. This book was released on 2007 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by more than 70 scientists from around the world, this publication assesses the state of the environment and the trends in ice and snow-covered regions (the cryosphere). It looks at the significance of climate changes for ecosystems and human well-being, both now and in the years to come, given that changes in ice and snow alter the distribution of the earth's heat and water, and influence regional and global ocean circulation. This publication is an official project of the International Polar Year 2007-2008.

Download or read book Contaminants in the Subsurface written by National Research Council and published by National Academies Press. This book was released on 2005-04-23 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.

Download or read book Dynamics of Ice Sheets and Glaciers written by Ralf Greve and published by Springer Science & Business Media. This book was released on 2009-08-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Ice Sheets and Glaciers presents an introduction to the dynamics and thermodynamics of flowing ice masses on Earth. Based on an outline of general continuum mechanics, the different initial-boundary-value problems for the flow of ice sheets, ice shelves, ice caps and glaciers are systematically derived. Special emphasis is put on developing hierarchies of approximations for the different systems, and suitable numerical solution techniques are discussed. A separate chapter is devoted to glacial isostasy. The book is appropriate for graduate courses in glaciology, cryospheric sciences, environmental sciences, geophysics and related fields. Standard undergraduate knowledge of mathematics (calculus, linear algebra) and physics (classical mechanics, thermodynamics) provide a sufficient background for successfully studying the text.

Download or read book Wind Water Work written by Adam Lucas and published by BRILL. This book was released on 2006 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the most comprehensive empirical study to date of the social and technical aspects of milling during the ancient and medieval periods.Drawing on the latest archaeological evidence and historical studies, the book examines the chronological development and technical details of handmills, beast mills, watermills and windmills from the first millennium BCE to c. 1500. It discusses the many and varied uses to which mills were turned in the civilisations of Rome, China, Islam and Europe, and the many types of mill that existed.The book also includes comparative regional studies of the social and economic significance of milling, and tackles several important historiographical issues, such as whether technological stagnation was a characteristic of late Antiquity, whether there was an industrial revolution" in the European Middle Ages based on waterpower, and how contemporary studies in the social shaping of technology can shed light on the study of pre-modern technology."
