Chapter 5: Minerals and Energy Resources
This chapter examines the non-renewable foundation of India's economy—minerals and energy resources—exploring their geological formation, uneven distribution, extraction challenges, and the critical transition toward sustainable energy alternatives. From iron ore mines to solar parks, we analyze how India's mineral wealth fuels industrialization while confronting environmental costs and energy security imperatives in a carbon-constrained world.
1. Minerals: Geological Wealth with Economic Consequences
Minerals are naturally occurring inorganic substances with definite chemical composition and physical properties, formed through geological processes over millions of years. India is endowed with significant mineral diversity, ranking among the world's top producers of several key minerals, yet facing critical challenges in sustainable extraction and value addition.
- The Mineral-Industry Nexus: Minerals form the raw material base for core industries—iron ore for steel, bauxite for aluminum, limestone for cement. India's industrial geography is heavily influenced by mineral location, creating growth poles like Jharkhand (minerals) versus Kerala (mineral-deficient).
- Geological Time vs Economic Time: Minerals form over geological timescales (millions of years) but are extracted in decades, creating fundamental non-renewability. India's high-grade iron ore reserves may last only 20-25 years at current extraction rates.
- The Royalty-Revenue Paradox: Mineral-rich states (Odisha, Jharkhand, Chhattisgarh) remain among India's poorest, highlighting the "resource curse" where extraction benefits corporations and central government more than local communities.
Critical Insight: India's mineral sector faces a triple imbalance: between reserves and production (abundant but underutilized), between extraction and value addition (exporting raw ores, importing finished goods), and between economic gain and environmental cost.
2. Historical Evolution of Mineral Extraction
India's relationship with mineral resources has evolved through distinct phases reflecting technological capacity and economic priorities:
- Ancient Craftsmanship (Pre-1500 CE): Small-scale mining for craft and construction. Iron pillars (Delhi, 4th century CE) demonstrate advanced metallurgy. Diamond mining in Golconda region famous worldwide.
- Colonial Exploitation (1757-1947): Systematic extraction for British industries. Coal for railways and steamships, iron ore for British steel plants, mica for electrical industry. Created India's first mining regions (Jharia coal fields, Singhbhum copper belt).
- Public Sector Dominance (1947-1990): Nationalization through MMDR Act 1957. Public sector giants: SAIL (steel), NMDC (iron ore), Coal India Limited. Focus on self-reliance but with inefficiencies and environmental neglect.
- Liberalization and Controversy (1991-Present): Private participation allowed, FDI in mining. Simultaneous growth of illegal mining, environmental movements (Niyamgiri), and policy reforms (MMDR Amendment 2015, 2021).
3. Energy Transition Milestones

| Dolomite | Odisha, Chhattisgarh, Andhra Pradesh | Bastar, Visakhapatnam | Steel flux, fertilizer, glass | Often occurs with limestone |
5. Energy Resources: Conventional vs Non-Conventional
A. Conventional Energy: The Fossil Fuel Triad
- Coal (53% of primary energy): India has world's 5th largest reserves (319 billion tons). Problems: 70% is poor quality (high ash), deep mining safety issues, Jharia fires burning for 100+ years. Transition to cleaner coal technologies (supercritical plants) ongoing.
- Petroleum (30% of energy, 85% imported): Mumbai High produces 40% domestic crude. Strategic vulnerability: price shocks affect economy, supply disruptions possible. Strategic petroleum reserves (5.3 MMT) provide 10-day buffer.
- Natural Gas (6% of energy): Krishna-Godavari basin major source. Cleaner alternative but infrastructure limited (15,000 km pipelines vs needed 30,000 km). City gas distribution networks expanding.
B. Non-Conventional Energy: The Sustainable Transition
- Solar Energy (Fastest growing): Installed capacity: 70 GW (2023). Advantages: India receives 5,000 trillion kWh/year solar insolation. Challenges: land acquisition, storage limitations. Bhadla Solar Park (Rajasthan) world's largest (2.2 GW).
- Wind Energy (Established technology): 42 GW capacity, mainly Tamil Nadu and Gujarat. Onshore potential: 302 GW at 120m hub height. Offshore wind policy (2019) targeting 30 GW by 2030.
- Hydropower (Clean but controversial): 47 GW installed, potential 148 GW. Large hydro (>25MW) reclassified as renewable (2019). Environmental and displacement concerns limit growth.
- Nuclear Energy (High potential): 7 GW from 22 reactors. Jaitapur (Maharashtra) to be world's largest (9.9 GW). Thorium reserves (12% of world) offer long-term potential via three-stage program.
The Energy Trilemma: India must balance three competing objectives: Energy Security (reliable supply), Energy Equity (affordable access), and Environmental Sustainability (low carbon). Current policy emphasizes renewable expansion while maintaining coal for base load, with natural gas as transition fuel.

8. Mining Issues and Environmental Justice
Major Mining Controversies:
- Niyamgiri Hills (Odisha): Vedanta's bauxite mining project opposed by Dongria Kondh tribe (2003-2013). Supreme Court's landmark decision (2013) upheld tribal rights under Forest Rights Act. Gram sabhas unanimously rejected mining.
- Bellary Iron Ore (Karnataka): Illegal mining scandal (2006-2011) involving ₹35,000 crore loss. Led to Supreme Court ban (2011), creation of monitoring committee. Highlighted politician-mining mafia nexus.
- Jharia Coal Fires (Jharkhand): Underground fires burning since 1916, affecting 42 square km. 70,000 families live in hazardous conditions. ₹10,000 crore master plan for relocation and fire control ongoing.
Environmental Safeguards and Challenges:
- District Mineral Foundation (DMF): Created under MMDR Amendment 2015. Mining companies contribute 10-30% royalty to DMF for local area development. Collected ₹49,000 crore (2015-2022) but implementation uneven.
- Mine Closure Framework: Mandatory mine closure plans with financial assurance. Scientific closure includes backfilling, soil stabilization, and monitoring for 5-10 years post-closure.
- Coal vs Renewables Dilemma: Despite renewable targets, coal production target: 1 billion tons by 2024 (currently 900 MT). Justification: energy security, employment (4 million in coal sector), and grid stability.
9. Essential Mineral and Energy Terminology
Ferrous vs Non-ferrous Minerals: Ferrous minerals contain iron (iron ore, manganese, chromite) and form backbone of metallurgical industries. Non-ferrous minerals contain no iron (bauxite, copper, gold) and are crucial for electrical, chemical, and jewelry industries.
Strategic Minerals: Minerals essential for economic development and national security where supply is vulnerable to disruption. India's list includes lithium, cobalt, rare earth elements (REE), tungsten. Currently 100% import-dependent for lithium (electric vehicle batteries).
Energy Intensity: Amount of energy required to produce one unit of GDP. India's energy intensity: 0.24 (2021), higher than global average 0.18 but declining due to efficiency improvements. Target: reduce 33-35% from 2005 levels by 2030.
Peak Load vs Base Load: Peak load is maximum electricity demand (usually evenings). Base load is minimum continuous demand. Coal/nuclear provide base load, while solar matches daytime peak. Energy storage crucial for renewable integration.
Mineral & Energy Revision Focus
Exam Strategy: For minerals, always mention state locations and industrial uses. For energy, balance current reality (coal dominance) with future transition (renewable growth). Use specific examples (Niyamgiri, Bhadla) to illustrate points.
Note: Minerals and energy questions often combine geography with current affairs (mining reforms, renewable targets) and environmental issues. Recent focus includes critical minerals for electric vehicles, offshore wind potential, and just transition for coal communities. Always update with latest capacity figures and policy changes.
