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 Encounters with Popular Pasts written by Mike Robinson and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the recognition that heritage is popular and popular culture is now readily transformed into heritage, whose meanings and myths reshape social life and political and economic realities, as well as re-make "tradition". The papers in this volume consider: What does popular heritage look like? To whom does it speak? Is it active in dissolving class and cultural boundaries or just in reproducing new ones? How do societies manage a heritage that is fluid, immediate and that straddles extremes of serious conflict and hedonistic frivolity? When and under what circumstances is the creation and expression of new cultural forms - popular culture - capable of being transformed into heritage?
