3 What is Hydroelectric power? Water is needed to run a hydroelectric generating unit. It’s held in a lake behind the dam, and the force of the water being released from the lake through the dam spins the blades of a turbine. The turbine is connected to the generator that produces electricity. After passing through the turbine, the water reenters the river on the downstream side of the dam.
5 The Advantages and Disadvantages of Hydroelectric Power. Once a dam is constructed, electricity can be produced at a constant rate.Hydropower is a fueled by water, so it's a clean fuel source.Hydroelectric power is not that expensive. Disadvantages:Dams are extremely expensive to build and must be built to a very high standard.People living in villages and towns that are in the valley to be flooded, must move out.Fish populations can be impacted if fish live in the dam.
6 How do Dams make Hydroelectric Power? Hydroelectric power is made as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced.Electricity is produced by a device called a turbine. Turbines are located inside dams. The falling water spins the magnets.
7 How is Hydroelectric Power Generated? Hydroelectric power is generated by using electricity generators to extract energy from moving water .
8 How is Hydroelectric Power very convenient? Hydropower is very convenient because it can respond quickly to fluctuations in demand. A dam's gates can be opened or closed on command.
