Comparision with Coal Energy and Nuclear Energy

 COAL POWER : 

1. Coal is called fossil fuel. It is formed from the remain of plants and animals for over million of years. 

2. Coal Power produces about 90% of world's total energy demands.

3. Much Smaller energy changes are involved during the combustion of coal. 

4. Generation of coal power is governed by the temperature and pressure. 

5. Similar products are obtained as a result of their combustion.

6. During combustion, There is no loss in total mass of coal. 

7. Atomic number of elements, involved, do not change.

8.Combustion of coal involves changes only in the electronic configuration of atoms and not in nuclei

9.Burning of Fossil fuel produces CO2, which contributes to green house effect. Coal also contains sulphur, nitrogen and other toxic gases which leads to air pollution. 

10.Air pollution can be minimised by adopting preventive measures.

11.Pollution level is low. 

NUCLEAR POWER :

1. Nuclear power is generated either from nuclear fission or fusion reaction.

2. Nuclear power produces around 11% of  world's energy needs.

3.The energy changes involved is many million times greater.

4.Temperature and pressure have no effect on generation of nuclear power. 

5.New products are formed. 

6. Loss of mass occurs, during combustion of nuclear fuels.

7.Atomic number of elements, involved, changes.  

8.Combustion of Nuclear fuels Involves changes both in electronic configurations and nuclei of atoms. 

9.The Nuclear reaction are very dangerous. Any leakage from the reactor may cause devastating nuclear pollution and hence huge money has to be spent on safety aspects.

10.Disposal of nuclear wastes is a big problem.

11.Radio active pollutants, released from nuclear power plants, are chronically hazardous. The dangerous radio waste cannot be buried in land without the risk of polluting the soil and underground water.
