Micro-Hydro Design Manual has grown from Intermediate Technology's field experiences with micro-hydro installations and covers operation and maintenance, commissioning, electrical power, induction generators, electronic controllers, management, and energy surveys.There is an increasing need in many countries for power supplies to rural areas, partly to support industries, and partly to provide illumination at night. Government authorities are faced with the very high costs of extending electricity grids. Often micro-hydro provides an economic alternative to the grid. This is because independentmicro-hydro schemes save on the cost of grid transmission lines, and because grid extension schemes often have very expensive equipment and staff costs. In contrast, micro-hydro schemes can be designed and built by local staff andsmaller organizations following less strict regulations and using 'off-the-shelf' components or locally made machinery.

Sustainable building from the ground up - the pros and cons of the latest green and natural materials and technologies From foundation to finish, a wealth of information is available on sustainable construction methods-entire volumes have been published on individual green and natural building techniques. But with so many different ideas to choose from, there is no single resource that allows an owner or builder to quickly and objectively compare the merits of each system for their particular project. Making Better Buildings cuts through the hype and provides the unvarnished facts about the upsides and downsides of the most widely discussed materials and technologies. Drawing on the real-world experiences of designer/builders, this comparative guide systematically and comprehensively examines each approach in terms of: Cost, sourcing, labor intensity, and ease of construction Energy efficiency, embodied energy, and environmental impacts Availability/accessibility Viable applications and future potential. Each chapter is rounded out by a chart which summarizes the material in a quick and accessible manner. Whether you are an owner preparing to build a green or natural home, or a conventional contractor determined to integrate sustainable alternatives into your existing construction practices, this up-to-the minute resource will help you make the best decisions for your project, while meeting your energy, efficiency, budgetary, and site-specific needs.

An essential addition to the Earthscan Planning & Installing series, Planning and Installing Micro-Hydro Systems provides vital diagrams, pictures and tables detailing the planning and installing of a micro-hydro system, including information on the maintenance and economics once an installation is running. The book covers subjects such as measuring head and flow, ecological impacts, scheme layouts, practical advice, calculations and turbine choice. Archimedes screws are also covered in detail, as well as the main conventional choices relevant to small sites. Micro-hydro refers to hydropower systems with a power rating of 100kW or less. A 100kW system will produce 100 standard units of electricity in one hour. These systems have been popular in some sparsely populated or mountainous countries for a number of years, but now new technology, less stringent regulation of grid connected generators and standardised turbine designs are encouraging more widespread interest in micro-hydro in the developed world. The renewable energy sector is growing at a remarkable rate, and whilst much attention has so far focused on solar and wind technologies, Europe and elsewhere have great potential for generating power from small scale hydroelectric installations. This book is aimed at site owners, designers and consultants who are looking to develop schemes in the micro-hydro scale – 5 to 100kW – although the concepts are applicable to smaller and larger schemes.

Efficient and effective irrigation of the land can have a dramatic effect on the agricultural output and the economic well-being of a community. At the heart of effective irrigation lies the problem of lifting or pumping water, and this handbook surveys the water-lifting technologies that are available and appropriate for smallholdings. It is a detailed and practical review of the options, especially for irrigation but also for other purposes, and the costs and general suitability of the different technologies are examined with the aim of enabling farmers and policymakers to make informed choices. This is an updated and expanded new edition of a book formerly called 'Water Pumping Devices'.

This second edition of the classic title on practical energy provision for isolated houses and remote locations has now been updated with a new chapter. Pumps as Turbine is a practical handbook for engineers and technicians involved in designing and installing small water-power schemes. It concerns the use of standard pump units as a low-cost alternative to conventional turbines to provide stand-alone electricity generation for isolated houses and remote communities. This second edition has been updated and extended to include a case study from a recent scheme installed in collaboration with ITDG Kenya. The pump selection process is described through this step-by-step example, where the site head would have been too low for a Pelton turbine. The case study demonstrates that now, possibly more than ever before, the use of pumps as turbines offers a reliable, low-cost option for rural electrification. Arthur Williams has been involved in micro-hydro research and development since 1987. While completing his PhD he worked with ITDG to set up successful pump-as-turbine demonstration schemes in the UK and Pakistan. He is now a senior lecturer at the Nottingham Trent University where he continues to work on micro- and pico-hydro power.

Rural Energy Services addresses the policy, market and sustainability aspects of defining and selecting technologies that will meet the demands for energy services by rural villages in a sustainable and reliable way. It offers a participative approach to the supply of energy services with a clear emphasis on the need for energy services, putting needs rather than technology first, and advocating that rural people, above all, know what they need and what will work for them. The handbook contains a full survey of energy resources and technologies and covers, in detail, the issues surrounding the decision-making processes involved, the implementation of energy schemes and an exploration of the policy, market and sustainability issues which are vital to the success of a scheme. The last section contains real case studies, covering projects which meet the energy service needs of rural people across the world today. The book was written as a resource for a series of workshops commissioned by the British Council and the UK Department for International Development, and provided the basis for workshops in countries such as Uganda, Brazil and India. Governmental and non-governmental energy strategists, donors, international and national development agencies, academics and financial institutions with responsibility for investment strategy will find this practical handbook highly valuable in their work.

This manual presents a range of analytical techniques to assist in evaluating and comparing energy technology options from a variety of important perspectives. The work distils experiences and draws lessons from previous rural energy activities, and presents a variety of relevant analysis tools that will contribute towards upgrading current decision making practices in rural energy development. The manual demonstrates how integrating technical, economic, social, institutional and environmental criteria forms the basis of 'good practice'in rural energy planning and policy development. Analytical techniques are described and illustrated with the help of case studies and information acquired from various parts of the developing world, in order to show how the techniques can be applied in real situations. The primary audience for the manual consists of energy analysts, policy makers, development workers and researchers in developing countries. The book will also be useful to academics interested in development issues, energy industry experts and decision makers at the local or government level involved in making decisions about energy and development policies.
