Week 5: Hydroelectricity
This week begins with a discussion of the nature of the hydro resource and its present contribution to world energy. This is followed by a summary of the basic science and an account of the development of water power, leading to a discussion of modern hydro turbine systems. The remaining sections are concerned with the problems and the potentialities of hydroelectricity.
By the end of this week, you will be able to:
- discuss at a basic level the magnitude of the world’s hydro resource and its present contribution to world total primary energy consumption
- describe at an introductory level the main features and the modes of operation of the principal types of water turbine
- describe at an introductory level the principle of pumped storage plants and their role in an integrated electrical supply system
- understand at an introductory level the environmental and social effects, beneficial and deleterious, of large-scale hydroelectricity, and the potentialities and problems of small-scale systems.
