In the first half of their book, the authors identify the demand factor within the overall view of the energy economy, widen the field of investigation to take in the other major links in the energy chain represented by reserves and production facilities, and analyze demand within the framework of overall energy policy. They stress that pricing policy is the main instrument of demand management, then proceed to explain how long-run marginal cost is the practical pricing basis and how energy-saving measures are the most logical way to check any rise in consumption. They then highlight the close interrelationship between supply and demand. The second part of the book presents case histories on Sri Lanka, Thailand, Bangladesh, the US, Costa Rica, and Brazil. 500 references, 62 figures, 109 tables.
