Give account of Thermal and Nuclear Energy of India.
Nuclear Energy :
- The energy generated from the fission of the atomic minerals such as Uranium, Thorium,
Plutonium is called ‘Nuclear Energy’. It has played an important role in the power development of India.
- The demand for energy has been increased with the increase of population in the country.
- The country has power crises as the production is insufficient to meet the requirement.
- To meet energy needs of the country nuclear power programme was formulated.
- The first nuclear power plant was started in 1969 at Tarapur near Mumbai with U.S.A assistance. Now there are 7 nuclear power stations in India.
Thermal Energy :
- The Energy generated by using fossil fuels like Coal, Petroleum and Natural gas is called thermal energy. It can be produced even from Nuclear fission and wood.
- It has certain advantages as against hydro-electricity. The initial capital involved in the construction of thermal plant is low and time requirement is short.
- The disavantages of thermal electricity are low efficiency in terms of heating value and higher operation cost.
Describe the Non-Conventional Energy resources in India.
The Power resources other than the traditional fossil and Mineral sources are known as ‘Non Conventional Power Resources’. They include Solar energy, Wind energy, Bio-gas, Sea waves, Biomass and geo-thermal etc. These reasources are inexhaustible and renewable in nature.
- These Power resources are found in abudance, pollution free, eco-friendly and not harm to the eco-system.
- They can be very conveniently supplied to urban as well as rural areas.
- In India conventional power resources are inadequate. Recently the rate of energy consumption has been increased.
- Hence there is urgent need to harness other alternative power resources.
- Top priority has been given for the development of non-conventional power resources.
- They are capable of solving the requirements. Such as supply of energy in decentralized manner and have sustainable environment.
- Thus the development of the these power resources is very essential.
Explain the Conservation and Management of Mineral and power resources.
- In General “Conservation” refers to the protection and preservation of natural resources and the natural environment for the future.
- This also includes the careful management of natural resources such as minerals, power resources, soil, forests etc., to prevent their destruction or over exploitation.
- The process of managing controlling or conducting is called ‘management’.
Need for Conservation :
- Minerals are exhaustible resources. They occur in nature in limited quantities.
- They cannot be replaced. They have taken millions of years to be formed.
- Human needs have increased greatly and minerals have been exploited without thinking of the Consequences.
- The present day energy, which runs our industries mostly comes from minerals.
- Hence it is necessary that we have to conserve and manage our minerals and power resources.
Explain the production and distribution of natural gas in India.
Natural gas is supposed to be the fuel of the 21st Century, because of its efficiency and clean,
Giogrcupbu) (U PUC)
- It is estimated that reserves of natural gas were 1330.26 billion cubic meters (BCM) India produces nearly 47 BCM annually.
- Bombay High : The Bombay high occupies the first place both in terms of reserves and the production of natural gas in India. It accounts for about 81 percent of the total gas production of the country.
- Gujarat and Assam are occupies second and third place respectively Khambhat in Gujarat and Khavaght in Assam are the major producers.
- It is also found in Mangalam in Tamilnadu, Linglu Andhra Pradesh and Jaisalmer in Rajasthan etc.
Production: India produced 47.9 billion cubic meters (bcm)ofnaturalgasin2011-12. In the recent years the production is increased with the increasing of demand.
- The efforts have been made by the Government of India to improve the production.
- There is a big gap between demand and indigenous production of natural gas. This has to be met through imports.
- ONGC and OIL has taken measures to increase the natural gas production.
Describe the important nuclear power plants in India.
There are 7 nuclear power stations in India they are –
- The first nuclear power plant was started in 1969 at Tarapur near Mumbai with USA assistance. It has installed capacity of 1400 MW.
- Ranapratap sagar plant near Kota in Rajasthan. It was established in 1973. Its capacity is 1180 MW.

There is a proposal to set up new nuclear power plants at Sri Sailam in Andhra Pradesh, Jaipur in Rajasthan, Tuticom in Tamilnadu, Talchar in Odhisha and Kolkata in West Bengal.
Explain the measures to conserve the mineral and power resources in India.
The following measures may be adopted to conserve mineral and power resources :
- Exploitation of new minerals : It should be explored in accessible areas like high moun-tains, ocean beds and polar regions.
- Conservation of minerals during mining : Conservation of minerals during mining such as coal and natural gas gets damaged and lost due to fire. This destruction has to be stopped.
- Maximum extraction of mined minerals : New technologies should be developed to obtain maximum metal and by products from ores.
- Multipurpose use to minerals : In order to gain maximum utility of the minerals.
- Safe godowns : After mining minerals should be stored properly to avoid the conditions which adversely affect their properties.
- Exploration of alternatives for minerals : It is essential to explore substitutes of minerals found in limited quantities.
- Re-use of minerals : It is another way through which mineral resources can be conserved. ’
- Use of power resources as raw materials : Power resources should not only be a source of power, rather they should be used in industries as raw materials.
- Prohibition of pollution: Mining activity have brought about many effect therfore it must be reduced.
- Developing alternative fuel sources of energy and use more renewable energy sources.
