In order to produce hydroelectric power, they pump water up to the top of a mountain, and as gravity causes the water flow down
again, it is used to turn the turbines. If it requires an input of energy to pump water up the mountain, why do they use this process? please help me!
Answer:Flowing water creates energy that can be captured and turned into electricity. ... The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
