Power and Efficiency

This program defines electric power and explores in general terms a variety of means by which it is produced, transmitted, and consumed. Efficiencies and inefficiencies relating to energy conservation are discussed in relation to power production, transmission, and consumption, with a particular focus on the efficiencies and inefficiencies associated with the conversion of electricity to light. Specific modules include Efficiency I: Power Production; Power; Efficiency II: Power Transport; Power Transmission; Power Consumption; Inefficiency I: The Light Bulb; and Inefficiency II: The Fluorescent Bulb. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act). A viewable/printable instructor’s guide is available online. A Shopware Production. (34 minutes)

Efficiency 1: Power Production and Energy Resources
Ell energy conversions come at a price--the price is entropy, the gradual disordering of energy. Power sources such as hydroelectric dams, coal, and nuclear power all produce environmental threats and public safety hazards.
