Microhydro power. Water power can be harnessed in many ways; tidal flows can be utilized to produce power by building a barrage across an estuary and releasing water in a controlled manner through a turbine; large dams hold water which can be used to provide large quantities of electricity; wave power is also harnessed in various ways. It is a technology that has been utilized throughout the world, by a diverse range of societies and cultures, for many centuries. Water can be harnessed on a large or a small scale. Micro-hydro power is the small-scale harnessing of energy from falling water; for example, harnessing enough water from a local river to power a small factory or village. This fact sheet will concentrate mainly at micro-hydro power.

In the UK, water mills are known to have been in use 900 years ago. Their numbers grew steadily and by the 19th century, there were over 20,000 in operation in England alone. In Europe, Asia and parts of Africa, water wheels were used to drive a variety of industrial machinery, such as mills and pumps. The first effective water turbines appeared in the mid 19th century and it was not long before they were replacing water wheels in many applications. In contrast to water wheels and the early turbines, modern turbines are compact, highly efficient and capable of turning at very high speed. Hydropower is a well-proven technology, relying on a non-polluting, renewable and indigenous resource, which can integrate easily with irrigation and water supply projects.

Visit the Service learning Portal

Service learning as a teaching method combines community service with academic instruction that focuses on critical, reflective thinking and civic responsibility. Service learning programs involve students in organized community service that addresses local and global needs, while developing their academic skills, sense of civic responsibility, and commitment to the community. Internships offer ways individuals can learn from valuable work experiences while also contributing to the host's mission.

Service learning using Appropedia helps to create an essential knowledge base for the world via learning experiences for individuals and classes. The Appropedia Foundation and the Appropedia community work with universities via service learning courses, as well as service learning programs to create these opportunities. Appropedia internships also offer opportunities for service learning.
