This three-section report provides introductory information about biogas production and its application to farm environments. The first section discusses the various components of a biogas production system (a system that converts organic wastes into a usable form of energy), explains the system's benefits and liabilities, and provides a brief…

This publication attempts to provide a non-technical overview of energy sources. Its purpose is to inform citizens so that they can more wisely shape their future. This publication is a companion to SE 025 935 which provides information on the social, political and economic aspects of the energy crisis. An inventory of present energy sources,…

Results reported in this document were obtained from a questionnaire distributed to higher education business officers and physical plant directors requesting information on total campus and individual building energy cost and consumption for the fiscal year July 1, 1975, through June 30, 1976. Usable reports were received from 330 (22 percent) of…

Presents 15 energy-related physics problems, including a brief indication of the essential features for solving each problem. Problems reflect various energy-related situations and involve different areas of physics. (SK)

The environmental awareness of village and rural children in Ghana differed from that of urban children. This study explores the knowledge of some Ghanaian children about water and full resources and their relationship to local development issues. (Author/RE)

Many people are invisible within and to the wider society. An adjunct aspect of that situation is that the marginalized are also invisible to one another. This "mutual invisibility" undermines the possibilities of cooperative transcommunal alliances. It is Cedric Sunray's ("Similarities between Tribes and the Ninth Ward,"…

An insatiable appetite for energy, a burgeoning world population, and a heightened awareness of climate change are focusing global attention on sustainability, an issue that may very well determine the future course of civilization. The pursuit of a sustainable lifestyle today is of paramount importance for future generations. Achieving…

Energy-yielding metabolism is an important biochemistry subject that is related to many daily experiences and health issues of students. An adequate knowledge of the general features of EYM is therefore important, both from an academic and social point of view. In a previous study, we have shown that high-school students present the misconception…

Keystone Science School and Keystone Center for Science and Public Policy programs blend learning in the natural world with developing mediation and conflict resolution skills. Since 2004, these two divisions of The Keystone Center in Colorado have partnered with the National Consortium for Specialized Secondary Schools of Mathematics, Science and…

Intended as a supplement to the units "Oil: Fuel of the Past" and "Coal: Fuel of the Past, Hope of the Future," this 3-4 day unit contains three activities which briefly explain the chronological development of energy resources and the formation and development of the Organization of Petroleum Exporting Countries (OPEC). The…

The author initially describes the basic physical principles associated with energy and the rise of energy usage in the United States. Also discussed are the ways energy limits growth and its use in various sectors of society. It is suggested that the decentralization of America's electrical system will save a great deal of energy. A variety of…

Explains the operation of the Magnetohydrodynamic (MHD) generator and advantages of the system over coal, oil or nuclear powered generators. Details the development of MHD generators in the United States and Soviet Union. (CP)

Outlines a Federal Power Commission report that lends credence to charges by several prominent petroleum researchers that the United States Geological Survey has consistently and hugely over estimated the amount of economically recoverable oil and gas left to be discovered in the United States. (Author/GS)

Describes a large-scale bio-conversion facility that will produce methane gas from raw manure. An innovative feature of the plant will be an algae farm/water recycling unit. (Author/MA)
