Energy Resources in India

Energy resources are crucial for India’s economic growth and development. They provide the power needed for agriculture, industry, transport, and other sectors. India relies on both conventional and non-conventional sources of energy. Here’s a detailed overview of the conventional energy resources:

Conventional Energy Resources

Coal

Uses: Primarily used for generating thermal power and in the smelting of iron ore.

Types:

• Bituminous Coal: Predominant in India, used mainly in power generation and industry.
• Lignite (Brown Coal): Found in coastal areas, used for power generation.

Geological Ages:

• Gondwana Deposits: The majority of India’s coal is from the Gondwana period.
• Tertiary Deposits: Found in Assam, Arunachal Pradesh, Meghalaya, Nagaland.

Major Coal Fields:

Gondwana Coal Fields:

• Damodar Valley: Includes Raniganj, Jharia, Bokaro, Giridih, and Karanpura.
• Godavari Valley: Includes the fields in the Godavari basin.
• Mahanadi Valley: Includes Talcher.
• Sone Valley: Includes coal deposits around Sone river.

Tertiary Coal Fields:

• Assam: Digboi, Naharkatiya, Moran.
• Meghalaya: Cherrapunji, Mewling, Langrin.
• Arunachal Pradesh: Namchik-Namphuk.
• Jammu and Kashmir: Kalakot.

Lignite Deposits:

• Tamil Nadu: Neyveli lignite fields.
• Puducherry: Coastal deposits.
• Gujarat: Coastal deposits.
• Jammu and Kashmir: Coastal deposits.

Important Mining Centres:

• Singrauli (Madhya Pradesh, also in Uttar Pradesh)
• Korba (Chhattisgarh)
• Talcher (Odisha)
• Chanda-Wardha (Maharashtra)
• Singareni (Telangana)

Key Points to Note

1. Coal: India has a significant amount of coal reserves, mainly bituminous type, crucial for power generation. The major coal-producing regions are in the eastern and central parts of India.
2. Petroleum: Crude oil production is concentrated in Assam, Gujarat, and offshore areas like Mumbai High. The refining capacity is distributed between field-based and market-based refineries.
3. Natural Gas: Found in association with oil and in specific fields, it plays a crucial role in energy production. Major reserves are located on the eastern coast, in Tripura, Rajasthan, and offshore areas.
