 Burning coal and petroleum produces harmful oxides of carbon, nitrogen, and

Sulphur which pollute the air leading to acid rain and greenhouse effect.

 Gases emitted by the combustion of fossil fuels are the main contributor to global
warming.

Thermal power plants

 Thermal power plants use steam produced by burning fossil fuels (mainly coal) to

move the turbines to generate electricity.

 The burning of coal heats up the water and forms steam that is used to run the
turbine.

 Usually, Thermal power plants are located near coal or oil fields as it is easier to

transmit electricity than transport coal.

A Model of Thermoelectric Production.

 The Tennis ball having three slits filled with semicircular (plaster or Metallic) tins
is our Turbine for generating electricity. Actually, the steam produced imparts

energy to rotor of turbine which can move shaft of the generator to produce

electricity. A very large amount of fossil fuels are burnt in Thermal Power Plant to
heat up water to produce steam.
