Distribution of Fossil Fuels in India:-

Coal(Black Gold)
  • Coal occurs in rock sequences mainly of two geological ages-Gondwana and tertiary deposits.
  • Gondwana Coal are located in coalfields occupying the Indian heartland, while tertiary coals occur in Assam, Arunachal Pradesh, Meghalaya and Nagaland.
  • Varieties of coal are Anthracite-lignite-bituminous-Peat.
  • Anthracite coal-the best quality coal comprising of 80-95% carbon. It is found only in small quantities in J&K.
  • Bituminous coal-the most widely used coal(40-80% carbon) found in Jharkhand, Orissa, WB, Chhattisgarh and MP.
  • Lignite coal- also known as brown coal(40-50% carbon). It is found Palna of Rajasthan, Neyveli of Tamil Nadu, Lakhimpur of Assam and Karewa of J&K.
  • Peat- it is the first stage of transformation of wood into coal and contains less than 40% carbon.
  • Coalfields of Orissa contain the largest reserves.
  • Over 90% of the lignite reserves are concentrated in Tamil Nadu.
  • The major coalfields of Jharkhand are in Jharia, Bokaro, Girdih and Karanpura. Jharia has been recognised as the store house of the best metallurgical coal in the country.
Petroleum or Crude oil
  • India’s most important oil-bearing area in the eastern part of the Himalayas is Assam. Digboi Oilfield in Lakhimpur district in Upper Assam marked a landmark in the development of India’s sources of oil. Naharkatiya oilfield situated near Digboi is the second largest oilfield in India.
  • The western coast Offshore fields have assumed great importance after the discovery of oil in Bombay High. Bombay High(Ratnagiri district) is the most productive oilfield.
  • In Gujarat, Cambay basin is the site of the main oil-bearing sands of Oligocene age. The Ankaleshwar Oilfield is the most important oilfield discovered so far in Gujarat.
  • Ahmedabad-Kalol region, also produces oil.
Natural Gas
  • Natural gas is produced in two ways-as an association gas along with crude production and as a free gas from exclusive gas fields.
  • The Ankleshwar gasfield, Bombay High, Bassein fields and Moran and Naharkatiya gasfields in Assam are among the main sources.
  • Natural gas is available as seepages in Nom-Chick, Miao Punga and Laptang Pung in Arunachal Pradesh, areas of Baramura range in Tripura and Jwalamukhi and Kangra in Himachal Pradesh.
  • Krishna-Godavari off-shore basin is reported to be the largest discovery of natural gas in the world.
  • Natural gas has also been discovered in Punjab(Ferozpur dictrict), WB(Midnapore district), J&K(in parts of Mausar-Maradpur) and Tamil Nadu(Thanjavur and Chinglepet districts).
Pipelines

  • Some of the important pipelines being Naharjatia-Nunmati-Barauni pipeline.
  • Jamnagar-Loni LPG pipeline
  • Haldia-Kolkata pipeline
  • India imports natural gas through transitional pipelines like Myanmar-Bangladesh-India gas pipeline, Turkmenistan-Afghanistan-Pakistan(TAP) pipeline.

Distribution of Renewable resources in India:-

Wind Energy
  • India has the 5th largest installed wind power capacity in the world.
  • The installed capacity comes mainly from across Tamil Nadu, Maharashtra, Karnataka and Gujarat.
  • Tamil Nadu generates around 35% of India’s total wind capacity and is the leader in wind energy in India.
  • The largest installation of wind turbines in the country so far has been in Muppandal-Perungudi near Kanyakumari in Tamil Nadu.Another wind turbine has been set up at Kayattar in Tamil Nadu.
Solar Energy
  • Since inception the Ministry of Non-Conventional Energy Sources(MNES) has been implementing a solar energy programme to provide electricity to rural and remote areas, make energy available for pumping of water for irrigation and drinking purposes.
  • The use of solar energy for thermal applications is well known in the country. The applications include water heating, cooking, drying, space heating, distillation and power generation.
  • Solar development programmes have been launched on several islands in the Bay of Bengal, in the deserts of Jodhpur in Aligarh and in Coimbatore.
  •  India is planning to install the World’s largest Solar Power Plant with 4,000 MW Capacity near Sambhar Lake in Rajasthan.
  • Gujarat has been a leader in solar power generation and contributes 2/3rd of the 900 MW of photovoltaics in the country. The State has commissioned Asia’s biggest solar park at Charanka village.
Ocean Energy
  • There are three ways of harnessing power from the high seas which includes taming the waves, harnessing the tidal power and using the differences in temperatures between the layers of the ocean i.e. by the technique of ocean thermal energy conversion(OTEC).
  • Experiments of OTEC are being carried out in Kulasekarapattinamin Tamil Nadu.
  • In India, tidal energy can be harnessed for power generation from potential sites such as Gulf of Kachchh and Cambay in Gujarat and Sunderbans in WB.
Biogas
  • Biogas is an efficient fuel when burnt in specially-designed stives for cooking purposes and in silk mantle lamps for lighting.
  • It can also be used in dual fuel engines for motive power when attached with alternators for generation of electricity.
  • The National Biogas Management Programme(NBMP) aims at providing cheap source of biogas energy and to produce and use enrich organic manure.
  • The biggest potential for Biogas is in UP followed by MP and Andhra Pradesh.
