Difference Between Thermal Power and Hydel Power:
The following are the points of difference between thermal power and hydel power.
|Thermal power is that power that is generated by consuming fossil fuels and atomic minerals. Coal, natural gas, petroleum, thorium, radium etc.
|Hydel power is generated by using water to move turbines. Water is the only source.
|Fossil fuels and atomic minerals are exhaustible resources. Hence thermal power may not be going on to be generated regularly in the future to come.
|Water is an inexhaustible resource. Hence we will go on generating hydel power till the time the sun and oceans are present in the universe.
|Its supply is uncertain.
|Its supply is perennial.
|The steam moves turbine to produce thermal power, water is also needed to make steam.
|The pressure of water is directly used to move turbines to produce hydel power.
|It is costly.
|It is cheap.
|Thermal power stations cause air and sound pollution.
|There is no pollution caused by hydel power stations.
|Thermal power stations can be built far away from the source of fossil fuels and atomic minerals.
|It is essential to set up hydel power stations on the rivers.
|The total installed capacity of thermal power in the country was 6200 crore kilowatts in 1996-97.
|The total installed capacity of hydel power in India was 2170 crore kilowatts in 1996-97.
