| Abstract: | In any water system which has excessive available energy (e.g. natural falls, irrigation systems, water supply, sewage or rain systems), the application of a pump instead of a turbine, for energy production, seems to be an alternative solution with easy implementation and considerable equipment cost savings. Micro-hydropower corresponds to a typical renewable energy source without any relevant impacts, and has multiple advantages, as a decentralised, low-cost and reliable form of energy. Unconventional solutions are in the forefront of many developing countries to achieve energy self-sufficiency. |
