📌 Key Points
- Iron ore major mineral - reserves concentrated in Odisha, Chhattisgarh, Jharkhand (60% of India's reserves)
- Coal third-largest reserves globally; found in Odisha, Chhattisgarh, Jharkhand; primary energy source in India
- Copper deposits in Madhya Pradesh; bauxite concentrated in Odisha; manganese, chromite also significant minerals
- Mining creates employment but causes severe environmental damage - deforestation, water pollution, air pollution
- Coal provides 70% of India's energy; thermal power plants major source of electricity using coal
- Petroleum and crude oil - India imports 80% of its crude oil needs; domestic reserves limited and declining
- Natural gas found with oil deposits and as coalbed methane; limited reserves; important for power and industry
- Hydropower provides 10-15% of electricity; dams on major rivers like Brahmaputra, Indus, Ganges, Narmada
- Industrial sector consumes 35% of energy; transport 20%, agriculture 20%, residential 25%
- Rising energy demand outpaces supply; power cuts common in many regions; peak demand hours face shortages
- Grid inefficiencies and transmission losses add to energy challenges; infrastructure needs upgrade
- Energy security concern due to import dependence of petroleum; fluctuating oil prices impact economy
- Solar power potential 300+ GW; increasing installations in southern and western India; cost declining rapidly
- Wind power concentrated in coastal and plateau regions; Gujarat and Tamil Nadu leading producers
- Biomass from agricultural waste potential energy source; geothermal potential in select regions
- Government target - 500 GW renewable energy capacity by 2030; requires huge investment
- Coal mining causes deforestation, destroys ecosystems, pollutes groundwater; ash disposal major problem
- Oil spills threat to marine ecosystems; Deepwater Horizon and similar incidents show ocean pollution risks
- Hydropower affects river ecosystems - changes water flow, impacts fish migration, affects downstream agriculture
- Thermal power plants cause thermal pollution in water bodies; coal mining generates greenhouse gases
📘 Important Definitions
⚠️ Common Mistakes
✗ Wrong: Thinking India has abundant petroleum reserves
✓ Correct: India imports 80% of crude oil; domestic reserves limited and declining; energy import dependence high.
✗ Wrong: Assuming coal mining only creates jobs without environmental cost
✓ Correct: Coal mining causes severe environmental damage - deforestation, water pollution; jobs temporary but damage permanent.
✗ Wrong: Believing hydropower is completely clean energy
✓ Correct: While renewable, large dams affect river ecosystems, fish migration, farming downstream; not impact-free.
✗ Wrong: Thinking renewable energy can immediately replace coal
✓ Correct: Transition takes time and investment; renewable intermittency requires storage technology; coal phase-out gradual.
✗ Wrong: Assuming minerals are distributed evenly across India
✓ Correct: Mineral deposits concentrated in specific regions - eastern India (coal, iron ore), uneven development.
✗ Wrong: Believing energy scarcity is only problem in power sector
✓ Correct: Infrastructure, inefficiency, transmission losses also major problems; not just shortage of energy.
✗ Wrong: Thinking petroleum independence not important for India
✓ Correct: Petroleum import dependence makes India vulnerable to global price shocks; strategic resource.
