Intended for nonspecialists, discusses various aspects of energy in historical terms. Areas addressed include brevity of the cheap energy era, exponential growth, and ideology/controversey (suggesting relationships between power plants and economic power). Examines general literature providing a framework for qualitative thinking about energy and…

Explains that the efficiency and the useful power available from a windmill turbine, of a laminar-flow model, will vary due to rotational kinetic energy of the downwind stream and turbulent mixing from outside the boundaries of the idealized stream. (GA)

Gives a brief description of open-circuit wind tunnels of rectangular cross-section and of how expanded polystyrene can be used to build a small one. (Author/GA)

Reviews the history of the steam turbine at sea from the 1880s to modern turbines. Presents several pictures of various types of turbines. (YP)

Describes four successful community programs dealing with waste management issues, developed with assistance from Keep America Beautiful System: litter prevention (Beatrice, Nebraska); composting yard waste (Centralia, Illinois); recycling (Lake Jackson, Texas); and waste-to-energy incineration (Gastonia, North Carolina). Notes related education…

Students live in a world that is powered by petroleum and other energy resources to an unsurpassed degree. The United States today consumes more than 24% of all the energy used in the world--and about 60% of this energy is provided by petroleum (oil and natural gas). The availability of abundant, inexpensive energy is the main reason that the…

Hydrogen energy systems are being developed to replace fossil fuels-based systems for transportation and stationary application. One of the challenges facing the widespread adoption of hydrogen as an energy vector is the lack of an efficient, economical, and sustainable method of hydrogen production. In the short term, hydrogen produced from…

A synthesis is developed to make biodiesel from vegetable oils such as soybean, sunflower, and corn oil, as an exercise in the laboratory. Viscosity measurements were used to gain an understanding of an intermolecular property of the biodiesel and that has limited the implementation of biodiesel on a wide scale basis, solidification at low…

The purpose of this booklet is to provide a basic understanding of nuclear fission energy and different fission reaction concepts. Topics discussed are: energy use and production, current uses of fuels, oil and gas consumption, alternative energy sources, fossil fuel plants, nuclear plants, boiling water and pressurized water reactors, the light…

The materials in this document are an extension of a catalog of occupational duties, tasks, and performance objectives relevant to maintaining automotive suspension systems, brakes, and steering mechanisms. This document provides the following for each occupational task within each duty: (1) a standard of performance; (2) the conditions under…

The different approaches to the generation of power from solar energy may be roughly divided into five categories: distributed collectors; central receivers; biomass; ocean thermal energy conversion; and photovoltaic devices. The first approach (distributed collectors) is the subject of this module. The material presented is designed to…

An introduction to geothermal energy is provided in this discussion of: (1) how a geothermal reservoir works; (2) how to find geothermal energy; (3) where it is located; (4) electric power generation using geothermal energy; (5) use of geothermal energy as a direct source of heat; (6) geopressured reservoirs; (7) environmental effects; (8)…

A survey to examine male and female attitudes toward locally proposed energy developments (e.g., coal production, refineries) in an Appalachian community is reported. Four hundred and eighty-five residents were questioned on whether they favor the proposed developments; whether they were currently employed in an energy-related occupation; and…

This paper presents a discussion of strategic planning within social institutions and provides a planning agenda that focuses on modern trends, forecasts, and projections. First, the background of the strategic planning process is reviewed, and historical changes in the nature of modern technology are delineated, including a transformation in…

This power trains manual is one of a series of power mechanics for training in the servicing of transmissions, etc., on farm and industrial machines. Materials provide basic information and illustrations for use by vocational students and teachers as well as shop servicemen and laymen. The ten chapters focus on (1) Power Trains: How They Work; (2)…
