The catalogue builds on both the earlier edition of The Power Guide and The Equipment Directory produced for training courses by the Technology and Development Group of the University of Twente in the Netherlands. The data has been comprehensively revised and updated on the basis of research carried out by members of the Technology and Development Group, Densi Tech BV of the Netherlands, and Intermediate Technology in the UK. The Power Guide will facilitate decision making by providing guidelines most appropriate renewable energy source as well as providing information on hundreds of products from almost 500 manufacturers and suppliers in over 40 countries throughout the world, covering the following areas:ΓÇó solar photovoltaic equipmentΓÇó wind pumps and wind generatorsΓÇó micro-hydro equipment, hydraulic ram pumps and water current turbinesΓÇó biomass pre-treatment. combustion and steam systems, and gasifiers.The information is divided into chapters by energy source, each with an introduction containing guidelines for equipment selection and the possibilities and constraints of using that source. This is followed by manufacturers" data with key information about the equipment. Guidelines are also included for the selection of internal combustion engines, and solar-thermal, biogas and ethanol equipment. This is essential reading for all those who are interested in renewable energies or responsible for selecting energy equipment throughout the world.

At the heart of effective irrigation lies the problem of lifting or pumping water, and this handbook, newly revised and reformatted, surveys the water-lifting technologies that are available and appropriate for smallholdings.
