Wind Pumping

This document examines the principles of wind energy conversion and looks at the types and characteristics of rotors, as well as the importance of matching rotor with pump.

Producer Gas for Power Generation

Producer gas is formed by the partial oxidation of a carbonaceous material, such as biomass or coal, in a furnace, generator, or 'producer' unit. This fact sheet outlines the method of doing this, and also other factors to consider like availability of resources and resulting pollutants.

Energy from the Wind

Wind turbines can be used for large-scale energy delivery, but can also be highly effective as small-scale remote applications.

Motors as Generators for Micro-hydro Power

Nigel Smith

This is a guide to the use of induction motors for electricity generation in remote locations. It is written as a practical handbook for engineers and technicians involved in designing and installing small water-power schemes for isolated houses and communities. This revised edition brings in new co...

Solar Photovoltaic Energy

This Technical Brief looks at the background of solar photovoltaic (PV) energy (in which sunlight is directly converted into electricity), the design of PV cell, modules and arrays, and configuration of PV systems.

Chimney Stoves and Smoke Hoods

Nearly half the world cooks on three-stone fires or basic stoves causing indoor air pollution. This brief looks at ways to reduce the pollution by using chimney stoves and smoke hoods to let the smokey air escape outdoors.

Stoves for Institutional Kitchens

Institutional stoves are used where large amounts of food need to be cooked. Typical examples are schools, hospitals, prisons and refugee camps.

Biogas

Biogas is a fuel used for cooking and lighting, made from dung and other organic waste.

Communities, Livelihoods, and Natural Resources

Stephen Tyler

This book presents cases from some of the poorest parts of Asia to illustrate how local innovations in participatory natural resource management can strengthen livelihoods, build capacity for local governance, and spark policy change. The book synthesizes results from a seven-year programme of appli...

Just One Planet

Mark Smith

The impacts of climate change are being felt all around the world and as they become more damaging and widespread, it is the 2.7 billion people in the world who live on less than $2 a day who will be hit first and hardest. The carbon emissions fuelling the lifestyles of people in the North are causi...
