No. It relies totally on the potential energy of a raised body of water.
You could argue that the turbines and generators used polluting energy to produce them, or the building of the power house and dams.
Once set up, there is no futher pollution caused in generating electricity.
Latin America has many rivers with a high flow rate hence the great ability to produce hydroelectric power (HEP). In Brazil, a lot of HEP is generated from the Parana river.
Hydroelectric power is used all the time. It has been estimated that hydroelectric power is responsible for up to 20% of the worlds electricity. A large percent of this from China.
Cruachan Power Station is a storage hydro-electric power station whereas a Normal Hydroelectric power station is produced and then used, no storage needed.
A hydroelectric generator requires two things to produce power; water and head. Water is obviously needed to spin the turbine, and head is the difference in altitude between the surface of the water in the reservoir above the generator and the water turbine at the generator.
The process of using falling water to spin turbines is called hydroelectric power.

hydroelectric power is an important for producing the power in the low loss of energy..energy is nothing but producing the power....so we can easily produce the power from hydroelectric power plant.
hydroelectric
Hydroelectric power plants. They have dams and generators. Water flows through a dam, which spins generators that produce hydroelectric electricity. (Fun Fact: The Hoover Dam is the biggest hydroelectric power plant.)
Once the dam is built and the power plant installed, there are no fuel costs and no pollution
hydroelectric causes noise pollution, but other wise there isn't any pollution caused by it.
No, hydroelectric power is produced from the movement of water spinning a turbine. Fossil fuels (coal, oil and natural gas) produce energy by burning.
they are eco friendly because no pollution is caused by them .
