Distinguish between the storage technique and the run-of-river techniques of hydropower.



Answer: Storage technique. In this technique, river water is blocked behind dams, which store or impound the water. Water is then released through the dam and as it moves through, it turns blades of turbines, which in turn, generate electricity. Electricity from the dam is sent to an electric grid through transmission lines. By storing and controlling the water in this fashion, a steady supply of electricity can be maintained. Alternatively, a run-of-river approach, can be used which does not disrupt the flow of river water.
