Hydro Energy |
![]() |
Hydro power is generated by using electricity generators to extract energy from moving water. Energy stored in the flow of rivers and oceans can be utilized by using a hydro kinetic power generating device that extracts the energy. Sea and river currents with very low speeds are widely available in many parts of the world. Even though the speed is below 6 km / hour or about 2 m / sec, the energy stored in the current can be used as a source of alternative energy. While the available conventional turbine and paddle wheel requires an average of 3-4 m / sec. Experts at the University of Michigan have created a machine that is called the VIVACE converter, known as the first device with the ability to take energy from most flows in rivers and seas throughout the world.

Micro Hydro & Pico HydroAn important application of hydro kinetic power for rural communities in Indonesia, which is used by YBUL, is micro and pico hydro technology. Micro hydro technology is a technology that utilizes the availability of large amounts of water to produce electricity. It has the following applications:
Micro hydro technology is an important technology for Indonesia. A great majority of the rural population still lives without the service of electricity. The beauty of electricity produced by small hydro turbine generator system is that the electricity is in alternating current form, and hence readily available for use to drive machines, such as sawing machines. Installation of small hydro systems in rural villages can be difficult if the approach is not right, because it requires a change of habit and attitude. Hence YBULs approach is to deliver the technology to a recipient with responsibility, including self management, self regulating etc. This is important because small hydro turbine generator systems require operators, maintenance and catchment area preservation together must become a village business activity. YBUL installed 3 (three) small hydro turbine generator systems under the sponsorship of USAID in the years 2001- 2002. Two of them were installed at PT CAKRA, a tea plantation company located in the hills of CIWIDE, south of the city of Bandung, West Java, Indonesia with a capacity of 120 kW each, and one turbine generator at the village Garung, south of the town Garut, also in West Java, with a capacity of 15 kW. In carrying out these approaches, started in mid 2008, YBUL has collaborated with different stakeholders through building a consortium that includes the following partners: The Gunung Gede Pangrango National Park, Bandung Institute of Technology (ITB), The Conservation International (CI), Bogor Pakuan University, Lembaga Pertanian Sehat, Community Organizations called Tunas Mekar and Gerakan Listrik Masyarakat (Gelimas), as well as Center for Energy and Power Studies (CEPS) – PLN. |
