About this book
The wind is a renewable energy resource that can never be exhausted and which avoids pollution. This makes it one of the most environmentally sound energy options available. Applied to water pumping, the wind has been central in the stimulation of many rural economies, such as the Great Plains in the United States, the Australian outback, and Argentina, and there is still great potential for future development of the wind-pumping resource. However, the scarcity of appropriate information on the technology, economics and potential has restricted dissemination in the developing world. "Windpumping: A Guide for Development Workers" overcomes this problem by taking the reader through every aspect of this topic in a systematic way. The appendix includes a list of international suppliers and manufacturers of windpumping equipment, together with a summary of their products and services.
