You asked: Which factors Favour the use of hydroelectric power?

Hydroelectric power plant reservoirs collect rainwater, which can then be used for consumption or for irrigation. In storing water, they protect the water tables against depletion and reduce our vulnerability to floods and droughts. 5. Hydroelectricity increases the stability and reliability of electricity systems.

What factors affect hydroelectricity?

The amount of electricity a hydropower plant produces depends on two factors:

  • How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam. …
  • Amount of Water Falling. More water falling through the turbine will produce more power.

What are 3 advantages of using hydroelectric power?

Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy.

What are 5 advantages of hydropower?

What are the two main factors in selecting a good source of hydroelectric energy?

Factors Affecting a Selection Site for a Hydroelectric Station

  • Raw Materials. The materials used in the construction of dams determine whether it will last for long or effectively serve its purpose. …
  • River Path. …
  • Geological Structure. …
  • Sufficient Water.

How is hydroelectric power good for the environment?

Hydropower is better for the environment than other major sources of electrical power, which use fossil fuels. Hydropower plants do not emit the waste heat and gases—common with fossil-fuel driven facilities—which are major contributors to air pollution, global warming and acid rain.

How is hydroelectric energy used?

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.

How effective is hydroelectric power?

Hydroelectric powerplants are the most efficient means of producing electric energy. The efficiency of today’s hydroelectric plant is about 90 percent.

Which of the following is not an advantage of hydroelectric power?

Which of the following is not an advantage of hydroelectric power plant? Explanation: Output of such plants is never constant. This is because of their dependency over flow rate of water in river which is seasonal.
