HOW WE GENERATE ELECTRICITY

HOW WE GENERATE ELECTRICITY 

In today’s world, we cannot think of any activity without electricity. Electricity has become an integral part of our lives .From small house hold purposes to heavy industrial works, everywhere we need electricity.

Where this electricity does comes from?

There are various power projects, Thermal power projects, Nuclear power project, Hydle power project etc. But the purpose remains same, that is generation of electricity and that too at same frequency for a particular country .A power plant converts one form of energy into another form of energy and to finally obtain electrical energy. In thermal, hydle and nuclear power project, heat, hydraulic and nuclear energies respectively are finally converted into electrical energy.

2.SOURCES OF ENERGY

1)  The Sun:-

The radiated heat energy by the sun can be utilized by generation of electrical power.

2)  The wind:-

The wind produced by the sun gets sufficient energy which can be utilized.

3)  Terrestrial heat or geothermal energy:-

During volcanic action, the material that comes out from the bowls of earth to form the volcanic explosion also produces the steam vents and hot spring.

4)  Ocean tides and waves:-

There is a tremendous energy in ocean tides and waves. At the time of hide tide, the gates are opened and water is stored in the tidal basin which can be used in generation.

5)  Water:-

Water at a high pressure or flowing with a velocity can be used to run turbine.

  6)  Fuels:-

   The main source of energy which may be solid, liquid or gas such as coal, oil or coal gas.

  7) Nuclear energy:-The tremendous amount of heat energy is librated by fusion of disintegration                 which can be utilized due to large amount of heat produced.
