The potential for wind energy in New Zealand gets a thorough going-over in a new book, Sustainable Energy -- Options for New Zealand. Since the co-author is long-time wind enthusiast Keith Dawber, this is hardly surprising. The former university physics lecturer has teamed up with teacher Dai Redshaw to present the range of options for alternative energy, including solar, biomass, hydro, geothermal, tidal and nuclear. The eight page wind chapter provides a general overview of wind energy in New Zealand, contrasting it with hydro; the two case studies are British as commercial wind development remains in its infancy in New Zealand. The 111 page book is probably too general for those involved in the industry itself, but that is not to condemn it. Sustainable Energy is intended to provide material to teach physics in context and covers a surprising amount of detail, packing in a broad overview with detailed case studies, relevant diagrams and sidebars. The writing is clear and, unlike many books in this sort of field, it does not suffer from being too earnest or preachy. The authors acknowledge where their sympathies lie and where matters of opinion -- rather than fact -- are expressed. The book is published by Otago University Press of Dunedin.
