describe how hydro energy can be converted into electrical energy write any two limitations of hydro energy
Answers
Hydropower is one of the most popular renewable energy sources in the present time.
In the hydropower plants the kinetic energy of the speedy water flow helps to spin the electricial turbines,and this spinning turbines generates electricity.
In this whole process the kinetic energy turns into electricial energy.
But there are many limitations too:
1)The energy production amount is not that great to use it for the commercial energy production.
2)The initial expenses is way too much for establishing a proper hydroelectricity plant.
3)Speedy water flow is mainly available in the higher altitudes, that's why the establishment process also becomes difficult in these higher altitude regions.
Answer:
Conversion of hydro energy into electrical energy
High rise dams are constructed on the river to obstruct the flow of water to collect it at a suitable height. The stored water has a lot of potential energy.
The water from a suitable height is allowed to fall on the blades of a turbine located at the bottom of a dam through a pipe.
Kinetic energy of flowing water rotates the turbine rapidly. Rotation of turbine helps the armature coil of generator to rotate rapidly in the magnetic field. Thus, hydroelectricity is generated.
Limitations of hydro energy:
(i) All river-sites are not suitable for construction of dams.
(ii) Large ecosystems are destroyed when submerged under the water in dam.
