- Coal – The quality of coal depends upon the % of carbon in it. So on this basis, the coal are divided into 4 categories –
- Pete – Carbon is less than 40%. This resembles wood and is worst coal form.
- Lignite – 40-55% carbon 3. Bituminous – 55-80% carbon 4. Anthracite – 80-95% carbon
- The gasses present in the coal are burned in coal refineries and coke is obtained for Iron-Steel Industry.
- 98% of Nation’s coal reserve and 99% production is from Gondwana coal. This Gondwana coal is primarily Bituminous. Tertiary coal is found mainly in North-East states and Tamil Nadu.
- Coal Reserves – According to Zoological Survey of India, a total of 255.25 billion tonnes of coal is there. 29.7 billion coking coal is here. Actual approve reserves of Lignite is 91.63 billion tonnes which is in Neville, Tamil Nadu. 88% of coal reserves are in 5 states – 1. Jharkhand (29%) Orissa (24.29%) 3. Chhattisgarh-MP (24%) 4. West Bengal (11%). Raniganj Coal Reserve (West Bengal) is biggest coal area of India. Here lies 11% expected and 9% visible/proved coal reserves.
Jharkhand – Leading state in Coal mining. 22.4% of nations total coal is produced.
- Jharia (Dhanbhad) – The biggest coal producer of Jharkhand. 60% of carbon is there. Jharia coal is sent to Iron-Steel plants.
- Bokaro (Giridhih) – District and Karherbari coal region.
- Karanpura Coal region (Palamu, Hazaribagh district)
- West Bengal – 11% reserve and 6% production.
- Raniganj Coal regionis spread in Bardhman and Birbhum district. Here coking coal is reserve.
- Orissa – 24% reserve and 17% production. Talchar region in Brahmani river valley.
- Chhattisgarh – Sarguja and Korba coal region.
- Madhya Pradesh – Singrauli region (supplies coal to Obra Thermal Plant)
- Jammu & Kashmir – Riyassi region had Anthracite coal.
- Andhra Pradesh – Singrani coal region (Godavari valley)
- Tertiary Coal – Assam-Makum, Neharkattia, Doigrung, Nambor and Longoi region.
- Meghalaya – Belyang, Doigring, Vemong region.
- Arunachal Pradesh – Namchik-Namfuk, Abor, Miri, Dapla, Aka and Miao hills.
- Lignite Coal – Neyveli mines in Tamil Nadu. Used in Thermal power plant.
- India is 3rd in coal production.
- Consumption of Coal – Coal is important source of commercial energy. 60-65% consumption – Thermal Power Plant, 12% - Steel Industries.
- Coal is also used in cement and fertilizer industries.
- Trade – India exports coal to Europe, Japan and Middle East and now a day it is imported on large scale.
Major Problems in Coal Mining
- Low Quality – Most of the India coal is non-coking which is not good for steel industry.
- Uneven Distribution – Most of the mines are in East India. North, West and South India are poor in coal deposits. It costs in transportation and cause uneven Economic-Industrial growth.
- Old Mining Methods – This is mainly based on human labour which causes low per capita growth and increases cost of mining.
- Energy Crisis – This is major problem in Damodar Valley Corporation.
- Environment Pollution – Coal mining and use of coal cause pollution. Thermal plants release poisonous gas an in mining area dust cause health problems.
India produces 1% of Worlds raw oil which is only sufficient for 23% of local demand.

- Ahmedabad – Kalou Region – Crude oil is sent to Koyali refinery. Kalol, Saanand, Dholka, Mehsaana and Vachraaj are important regions of oil production.
- Western Offshore Region
- Bombay high – leading all site of country, 65.92% of total production of country, 330 million tonnes oil and 37,000 million gas reserves are here, spread in 2500 km area and had high % of petrol and kerosene.
- Bassein Region – South of Bombay high
- Aliabate – In Bay of Khambhat near Aliabate Island.
- Eastern Coastal Region
- It includes deltas of Kaveri, Krishna and Godavari rich in mineral oil and Natural gas.
- Krishna-Godavari offshore basin Ravaa regions will give 10-30 lakh tonnes oil per year.
- Amlapuram Basin could give 3600 barrels per day.

- So as to cop out with increasing demand there are plans to build pipelines from Iran, Myanmar and Central Asia to India to bring Natural Gas.
- Mainly Generated from four sources - 1. Coal (Thermal electricity) Water (Hydel Power)
- Nuclear Energy and 4. Natural Gas.
- 60% Thermal Power Plants, 22% Hydel Power and2.5% Nuclear Power Plants.
- NTPC (1975) develops coal based power plants.
- There is more increase in Thermal electricity than Hydel and Nuclear because Hydel and Nuclear power requires more investment, appropriate places and long building time than Thermal plants.
- Due to the improved living standards, urbanization, industrialization, transport development there is increase in the electricity demand. Due to the mismanagement State Electricity Board and their weak financial status had caused growing electricity crisis. Industries requires maximum electricity (38%), after that common house hold (24.3%), Agriculture (22%), Commercial (8.8%) and Railway (2.3%). Due to use of pumping set and machines in agriculture the demand for th electricity had increased. There is decline in Industrial and Railway demand.
- Maharashtra is leading in Electricity production.
- Electricity is the subject of state and the production and distribution is done by the State Electricity Board.
- National Power Training Institute (Faridabad) trains the Electricity board workers.
- Andhra Pradesh is leading in electricity production then is Karnataka and Maharashtra comes.
- Hydel power is more developed in the Southern part (South India).
