Back to basics: direct hydropower

One hydropower configuration that deserves considerable attention is a water turbine directly powering machinery, without the intermediate step of generating electricity. The implementation of this form of direct hydropower doubles the effectiveness of a small scale electric hydropower installation. This advantage can be used to increase the energy production of an existing water power site. It also means that more potential water power sites become available, and that relatively small streams and rivers can be shared by several hydropower units. Because of its higher efficiency a direct hydropower system is also cheaper.
