dropower -- Energy from Moving Water.
Of the renewable energy sources that generate electricity, hydropower is the most often used. It is one of the oldest sources of energy and was used thousands of years ago to turn a paddle wheel for purposes such as grinding grain. Because the source of hydropower is water, hydroelectric power plants must be located on a water source. Therefore, it wasn’t until the technology to transmit electricity over long distances was developed that hydropower became widely used.
Mechanical energy is derived by directing, harnessing, or channeling moving water. The amount of available energy in moving water is determined by its flow or fall. Swiftly flowing water in a big river, carries a great deal of energy in its flow. So, too, with water descending rapidly from a very high point, like from a dam.
Some people regard hydropower as the ideal fuel for electricity generation because, unlike the nonrenewable fuels used to generate electricity, it is almost free, there are no waste products, and hydropower does not pollute the water or the air. However, it is criticized because it does change the environment by affecting natural habitats.
Principle of hydropower
The principle of hydropower is that the potential energy of the water stored at great heights in the dam is converted in to kinetic energy by allowing the water to flow at high speed. Then the kinetic energy of flowing water used to generate electricity.
In hydroelectric power station, the flowing water is stopped in high altitude rivers by constructing dams and is stored in huge reservoir behind the dam. The water stored possessed very large amount of potential energy. Then the water is allowed to fall through pipes on the blades of big water called turbines. These turbines are connected to electric generators.
when the shaft of the turbines rotates, the generator coil also rotates rapidly and produce electricity. The basic outlines of hydroelectric power station
Advantages:
(1) It does not cause any pollution
(2) It is a cheap and renewable source of electricity which will never get exhausted
Disadvantages
(1) The construction of dam on rivers causes a variety of geological changes in the down stream areas of the river. It was variety of plants and animals and human settlements get submerge in the water reservoir formed by the dam. Therefore, many plants and trees are destroyed and animals get killed.
(2) The soil in the down stream becomes poor in quality.

Hydropower Plant
____________________________
Principle:-
The moving water possesses kinetic energy. The water-wheel is a device used for obtaining energy from flowing water.
About:-
The energy of naturally flowing water in a river is generally stored beyond dams as potential energy and then for the used to generate electricity. The electricity produced by using the energy of flowing water is known as hydroelectric power. The most important advantage of water energy is that like the wind energy it does not cause any pollution. An important limitation of this energy is that falling in water is not available in plenty everywhere to turn water-wheels and run the machines needed to generate electricity.
Working:-
A dam or reservoir is made over a river. The energy of stored water in the dam is potential energy. the water in a dam is allowed to fall on the water-wheel or turbine. As a result of this, the turbine rotates whose axle is connected with the armature of the generator.
The armature of the generator rotates within two poles of a strong magnet. The rotation of the armature of the generator between two poles of a strong magnet gives rise to electric current or electricity. This electricity is transmitted sub-stations through a transformer for the distribution to the houses and factories.
