Introduction

India is endowed with significant mineral and energy resources, though their distribution is highly uneven -- concentrated primarily in the peninsular plateau region (Chota Nagpur Plateau, Deccan Plateau, and their extensions). The country's economic development and energy security depend on the judicious exploitation of these resources.

This chapter covers the distribution, production, and strategic significance of India's major minerals (metallic and non-metallic), fossil fuels (coal, petroleum, natural gas), nuclear minerals (uranium, thorium), and renewable energy resources (solar, wind, hydro).

Coal

Coal is India's most abundant fossil fuel and the backbone of the country's energy sector, accounting for over 50% of primary energy supply and fuelling about 75% of electricity generation. India is the world's second-largest coal producer after China.

Types of Coal (by Carbon Content)

Peat<25%LowestNot commercially mined in India

Distribution of Coal in India

India's coal deposits are divided into two geological ages:

Gondwana Coal (~98% of reserves, ~99% of production):

  • Formed during the Permian Period (~250 million years ago) in the Gondwana sedimentary basins.
  • Found in river valleys of the Damodar, Son, Mahanadi, Godavari, and Wardha.

Tertiary Coal (~2% of reserves):

  • Younger, lower quality (mostly lignite and sub-bituminous).
  • Found in Assam (Makum coalfield), Meghalaya, Arunachal Pradesh, Nagaland, Jammu & Kashmir, Tamil Nadu (Neyveli), Rajasthan.

Nuclear Minerals

India's nuclear energy programme, based on the three-stage strategy envisioned by Dr. Homi Bhabha, relies on two key minerals: uranium and thorium.

Uranium

AspectDetail
Total estimated reserves~4,25,570 tonnes of in-situ U₃O₈ across 47 deposits (DAE Year End Review 2024); ~2,17,560 tonnes augmented between April 2015 and September 2025 — sufficient for India's planned PHWR fleet expansion

UsesElectronics, magnets, EV batteries, defence (missile guidance), wind turbines, smartphones
Strategic concernIndia's critical mineral policy (2023) identifies REEs as strategic; aims to reduce China dependence through domestic mining and international partnerships (e.g., Quad Critical Minerals Partnership)

Renewable Energy Resources

India has set an ambitious target of 500 GW of non-fossil fuel-based installed capacity by 2030 (announced at COP26, Glasgow, 2021). As of March 31, 2026, India's total non-fossil installed capacity stands at 283.46 GW (renewable energy 274.68 GW + nuclear ~8.78 GW), representing ~54% of total installed capacity — achieving the 50% Panchamrit pledge five years ahead of schedule (PIB, April 2026).

India's Critical Mineral Strategy

In June 2023, the Ministry of Mines released the report of the expert committee identifying 30 critical minerals essential for India's energy transition, defence, telecommunications, semiconductors, and high-technology manufacturing. The list includes lithium, cobalt, nickel, graphite, niobium, germanium, gallium, indium, tantalum, tellurium, titanium, tungsten, vanadium, zirconium, and 17 rare earth elements (REEs). The strategy aims to reduce dependence on a single-country supply chain (China dominates ~60% of REE mining and ~85% of refining).

Recent Developments (2024–2026)

Record Coal Production — 1 Billion Tonnes Crossed (FY 2024–25)

India surpassed the historic threshold of 1 billion tonnes (1.03 BT) of total coal production in FY 2024–25, a first for India and only the second country globally after China. Coal India Limited (CIL) produced 0.75 BT (781.06 MT — record for CIL); private captive and commercial mines contributed 197.5 MT — up 28% year-on-year. Coal dispatch reached 1,025 MT. India's coal imports declined 8.4% during April–December 2024, saving ~$5.43 billion in forex. India ranks as the world's second-largest coal producer. Gondwana coalfields (Jharkhand, Chhattisgarh, Madhya Pradesh, Odisha, West Bengal) account for ~98% of India's total coal reserves.

FY 2025-26 update: India's captive and commercial mines crossed 200 MT production for the first time in FY 2025-26, reaching 210.46 MT (+10.22% YoY from 190.95 MT); coal dispatch 204.61 MT (+7.35%). India's total all-source coal production for FY 2025-26 is projected at ~1.15 billion tonnes — setting another record (Ministry of Coal / PIB, 2026). The Ministry of Coal's FY26 production target was 1,157 MT — CIL target: 875 MT; SCCL: 72 MT; captive/commercial: 210 MT.

UPSC angle: Coal geography, Gondwana vs Tertiary coalfields, Coal India's dominance, coal vs renewable energy transition tensions — all are high-priority GS1 and GS3 topics.

Solar Energy — 100 GW Installed Capacity Milestone (January 2025) and Record 2025 Expansion

India crossed the landmark threshold of 100 GW of installed solar capacity on January 31, 2025 (at 100.33 GW), making it only the third country in the world (after China and the USA) to cross this milestone — a 35-fold increase from 2.82 GW in 2014. By November 2025, solar capacity had risen to 132.85 GW (41% year-on-year); by March 2026, ~150 GW (PIB). Total non-fossil installed capacity crossed 283 GW by March 2026 — achieving India's Panchamrit COP26 pledge (50% non-fossil capacity) five years early. India added a record 44.51 GW of renewable capacity in 2025 — nearly double the 24.72 GW added in 2024. Solar contributes ~47% of India's total renewable installed capacity; wind capacity ~56 GW (4th globally). State-wise solar leaders: Rajasthan (~20 GW), Gujarat (~12 GW), Karnataka (~10 GW), Tamil Nadu (~8 GW). India targets 500 GW non-fossil fuel capacity by 2030.

UPSC angle: Prelims — Solar 100 GW crossed (Jan 31, 2025); ~150 GW by March 2026; India 3rd globally after China and USA; Rajasthan leading state. Mains GS3 — 500 GW target; state-wise solar resources; India's NDC commitments; Panchamrit pledges at COP26.


Critical Minerals — India's Lithium Discovery and Strategy (2023–2025)

Following the Geological Survey of India's discovery of approximately 5.9 million tonnes of lithium deposits in the Salal-Haimana area of Reasi district, Jammu & Kashmir in 2023, India intensified its Critical Minerals Mission. The Union Budget 2024–25 waived customs duties on 25 critical minerals, recognising their importance for battery storage, electric vehicles, and clean energy. India signed bilateral mineral partnerships with Australia, Canada, and the US under the Minerals Security Partnership (MSP). The National Critical Mineral Mission (NCMM) — approved January 2025 with a total outlay of ₹34,300 crore over 7 years (GoI share ₹16,300 crore + PSU investment ₹18,000 crore) — aims to secure domestic mining and overseas acquisition of lithium, cobalt, nickel, graphite, and rare earth elements essential for India's 500 GW renewable energy and EV transition goals.

KABIL overseas progress: KABIL (Khanij Bidesh India Ltd — JV of NALCO, HCL, MECL) signed a ₹200 crore (~$24 million) lithium exploration agreement with Argentina's CAMYEN for five blocks (~15,703 ha) in Argentina's Catamarca Province (MINING.COM). Exploration and development work is ongoing under this January 2024 agreement. KABIL is also pursuing cobalt and nickel assets in Australia, Chile, and Africa under the Minerals Security Partnership framework.

UPSC angle: Critical minerals geography, lithium in J&K, Minerals Security Partnership, and the connection between critical mineral access and India's clean energy transition are emerging high-priority GS1 and GS3 topics.


For Prelims: Coal types and their carbon content, state-wise mineral distribution (Jharkhand = uranium at Jaduguda, Kerala = thorium in monazite, Odisha = chromite at Sukinda, Karnataka = gold at Kolar), Mumbai High as the largest offshore oil field, and India's renewable energy targets (500 GW by 2030) are frequently tested.

For Mains GS-I/GS-III: Questions ask about the spatial distribution of minerals and their link to industrialisation, energy security challenges, India's three-stage nuclear programme, and the renewable energy transition. Use maps and data tables in your answers.

Key Terms

Offshore Wind Energy

  • Definition: Offshore wind energy is electricity generated by wind turbines installed in seas and oceans — typically within a country's territorial waters or Exclusive Economic Zone (EEZ) — where stronger, steadier winds yield higher capacity factors than onshore wind farms.
  • Context: Turbines are either fixed-bottom (anchored to the seabed in shallow water) or floating (moored in deeper water beyond ~60 m). Offshore winds are faster and more consistent than over land, giving capacity factors of roughly 35-50% versus 25-35% for onshore wind. India notified its National Offshore Wind Energy Policy in 2015, naming the Ministry of New and Renewable Energy (MNRE) as the nodal agency and setting a target of 30 GW of offshore wind by 2030, drawing on an estimated ~70 GW potential off Gujarat and Tamil Nadu.
  • UPSC Relevance: This is a foundational geography and energy-resources concept that underpins UPSC questions on renewable energy, India's energy transition, climate commitments, and marine resource use within the EEZ. In Prelims it can be tested via the nodal ministry (MNRE), the EEZ extent (200 nautical miles), and policy/scheme facts such as the 2015 policy and the 2024 Viability Gap Funding scheme; in Mains (GS1 geography of resources, GS3 energy security and environment) it links to coastal wind regimes, the fixed-bottom vs floating distinction, and the challenges of scaling marine renewables. No direct PYQ is cited here; treat it as a foundation concept supporting the wind/renewable-energy question family.

Nuclear Power in India

  • Definition: Nuclear power in India is electricity generated from controlled nuclear fission in atomic reactors, operated mainly by the Nuclear Power Corporation of India Limited (NPCIL) under the Department of Atomic Energy, and built around Homi Bhabha's three-stage programme designed to exploit India's modest uranium and vast thorium reserves.
  • Context: India's atomic energy effort dates to the Atomic Energy Act, 1948 and the establishment of the Atomic Energy Commission, with Homi Bhabha articulating a three-stage closed fuel cycle in 1954. Constrained by limited domestic uranium, the strategy aims to ultimately tap India's large thorium deposits found in the monazite sands of the southern and eastern coasts. The 2008 India-US civil nuclear deal and the NSG waiver ended India's nuclear isolation, enabling imports of uranium and reactors. As of 2025-26 nuclear contributes only a small share (about 2-3%) of India's electricity, but the government has set sharply higher ambitions through the Nuclear Energy Mission.
  • UPSC Relevance: This is a foundational, high-yield topic that underpins questions across GS1 (energy resources and geography), GS3 (energy security, science and technology, indigenous innovation) and Prelims (reactor types, plant locations, three-stage programme). Prelims commonly tests factual recall such as PHWR vs FBR fuel and moderators, the role of thorium and plutonium-239, and the locations of plants like Tarapur, Kudankulam, Kakrapar and Kalpakkam. Mains framing typically links nuclear energy to climate commitments, net-zero by 2070, energy security and the public-private participation debate. No verified PYQ is cited here; treat reactor-type and fuel-cycle facts as the most exam-critical anchors.

Coal Gasification

  • Definition: Coal gasification is a thermo-chemical process that converts solid coal (or lignite) into a gaseous mixture called synthesis gas or "syngas" — chiefly carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and methane (CH4) — by reacting the coal at high temperature with a controlled amount of oxygen and/or steam. The syngas is then used as a feedstock to make fertilisers, methanol, synthetic natural gas, hydrogen and chemicals, rather than being simply burnt for power.
  • Context: India holds large coal reserves but imports most of its natural gas and downstream petrochemicals, making coal gasification an attractive route to substitute costly imports. Globally the technique exists in two broad forms — surface gasification in engineered plants and underground (in-situ) coal gasification of unmineable seams. India has placed gasification at the centre of its "clean coal" strategy, setting a National target to gasify 100 million tonnes (MT) of coal by 2030, while also acknowledging that the process is energy- and water-intensive and emits significant CO2 unless paired with carbon capture.
  • UPSC Relevance: This is a foundational GS3 concept that underpins questions on energy security, import substitution, clean-coal technology and the energy-environment trade-off. For Prelims, candidates should know that syngas is mainly CO + H2, the products derivable from it (urea, methanol, SNG, hydrogen), and the flagship Surface Coal/Lignite Gasification schemes. For Mains (GS3), it links to energy security, fertiliser/import dependence, and the climate critique that gasification can emit more CO2 than direct coal combustion, raising the need for CCUS. No verified UPSC PYQ exists for this exact term, so it is best deployed as supporting material in energy-security and clean-energy answers.

Rare Earth Elements

  • Definition: Rare Earth Elements (REEs) are a group of 17 chemically similar metallic elements — the 15 lanthanides plus scandium and yttrium — that, despite the name, are relatively abundant in the Earth's crust but rarely found in economically concentrated, easily mineable deposits.
  • Context: REEs are indispensable to modern high-technology and clean-energy supply chains, especially neodymium-iron-boron (NdFeB) permanent magnets used in electric-vehicle motors, wind turbines, smartphones and defence systems. China dominates the entire value chain — holding roughly 48% of global reserves and about 69% of mine output, and over 90% of refining and magnet-making capacity (USGS Mineral Commodity Summaries 2025; IEA). India holds the world's third-largest reserves (~6.9 million tonnes) but produces less than 1% of global supply, prompting the National Critical Mineral Mission (launched January 2025) to build a domestic value chain.
  • UPSC Relevance: REEs are a high-yield GS3 topic spanning economy (critical-mineral security, import dependence), science and technology (clean energy, electronics, defence applications) and geography (mineral resources, beach-sand placer deposits). The Prelims angle tests factual recall — the 17 elements, light vs heavy REEs, monazite as India's chief source, and bodies like IREL and the National Critical Mineral Mission. The Mains angle frames REEs through supply-chain vulnerability, China's near-monopoly and export controls, and India's strategy for self-reliance and resource diplomacy. This is a foundational concept underpinning questions on critical minerals, energy transition and strategic resource geopolitics.
