Hydropower (Large-scale)

المُلخص التنفيذي. Hydropower is a method of generating electricity that uses moving water (kinetic energy) to produce electricity. In large-scale hydropower plants the moving water drives large water turbines, and dams are needed to store water in lakes, reservoirs and rivers for later release. Stored water can be used for power
