Concept:

• Energy is required for all activities.
• It is needed to cook, to provide light and heat, to propel vehicles and to drive machinery in industries.
• Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and electricity.
• Energy resources can be classified as conventional and non-conventional sources.
• Conventional sources include firewood, cattle dung cake, coal, petroleum, natural gas and electricity (both hydel and thermal).
• Non-conventional sources include solar, wind, tidal, geothermal, biogas and atomic energy.
• Energy sources can also be classified as renewable(that can be regenerated) and non-renewable (cannot be regenerated)

Explanation:

• All conventional sources produce energy by combustion and hence produce carbon dioxide
• An exception is a hydel energy
• Hydroelectricity is generated by fast-flowing water, which is a renewable resource
• On the other hand, non-conventional energy sources do not cause pollution and use renewable source of energy.
• Nuclear energy is obtained by altering the structure of atoms. When such an alteration is made, much energy is released in the form of heat and this is used to generate electric power

• India has a huge potential for generating nuclear power.
• Uranium and Thorium, which are available in Jharkhand and the Aravalli ranges of Rajasthan are used for generating atomic or nuclear power.
• The Monazite sands of Kerala is also rich in Thorium. 
• The first nuclear power plant in India was established at Tarapur, Maharashtra in 1969
• At present, there are 7 nuclear power plant in India with 22 operating reactors having a capacity of 6780 MW
