What is Hydro- Electric Energy?
The electricity made by the motions of generator turbines making use of the flowing water is known as the hydroelectric energy or the hydel energy. All through the rain or the snowfall, the potential energy of those water molecules is being converted as the kinetic energy. Whenever the ice at the higher altitudes melts, the potential energy of the gravity will be converted as the kinetic energy flowing as the river or stream of water.
If you consider storing rainwaters and chooses to construct a dam, water would be having a higher potential energy. Whenever the water is allowed to fall from such height, its potential energy will then be converted as the kinetic energy. The kinetic energy of the flowing water could be used for rotating the blades of the turbine together with the armature of the electric generator in order to generate current.
On the other hand, the hydroelectric power station situated from Ukai and on the Tapi River of Gujarat, they generate 300 MW of the current. The hydroelectric power station has been also constructed on Narmada Rover at the Sardar Sarovar dam. With mini hydroelectric power plants, they could be constructed upon the hilly areas or for small dams, whenever the water is flowing through the height of about 10 meters.
Advantages of Hydro- Electric Energy
* Whenever it is already completed, the hydroelectric power station only needs maintenance as well as proper management, which is definitely not costly.
* The constructed dam for hydroelectric power station could also be used for both irrigation and preventing floods.
Disadvantages of Hydro- Electric Energy
* The installation cost of the hydroelectric power plant could be high
* The need of large area for the installation of the dame might lead for the destruction of the forests, causing ecological imbalance.
