Conservation Of Minerals

1. Dependence on Minerals:

  • Industries and agriculture are heavily reliant on mineral deposits.
  • Workable mineral deposits form only 1% of the Earth’s crust.
  • Mineral resources are finite and non-renewable.
  • Geological processes of mineral formation are slow, making replenishment rates negligible.
  • Continuous extraction leads to higher costs and declining quality of ores.

2. Sustainable Use of Minerals:

  • Planned and sustainable resource usage is essential.
  • Technologies for using low-grade ores at reduced costs need to be developed.
  • Recycling metals and using substitutes conserve mineral resources.

3. Energy Resources:

  • Energy is essential for cooking, lighting, heating, transportation, and industrial machinery.
  • Energy sources are classified as:
    a. Conventional sources: Coal, petroleum, natural gas, firewood, cattle dung cake, hydel, and thermal electricity.
    b. Non-conventional sources: Solar, wind, tidal, geothermal, biogas, atomic energy.

4. Coal:

    b. Tertiary coal: Found in Meghalaya, Assam, Arunachal Pradesh, Nagaland.

5. Petroleum:

  • The second major energy source in India.
  • Provides fuel, lubricants, and raw materials for industries like textiles, fertilizers, and chemicals.
  • Petroleum occurrences:
    a. Found in anticlines, fault traps, and porous rocks (limestone/sandstone).
    b. Major production areas: Mumbai High, Gujarat, Assam.

6. Natural Gas:

  • Infrastructure: The HVJ pipeline links western and northern India.

7. Electricity:

  • Index of development due to wide applications.
  • Generated in two ways:
    a. Hydro electricity: Renewable, generated by flowing water.
    b. Thermal electricity: Generated using fossil fuels like coal, petroleum, and natural gas.

8. Non-Conventional Sources of Energy:

  • Importance due to fossil fuel shortages and environmental concerns.
  • Examples: Solar, wind, tidal, biomass, geothermal energy.

11. Wind Energy:

  • High potential in India.
  • Major wind farm clusters: Tamil Nadu, Gujarat, Karnataka, Maharashtra, Kerala, Lakshadweep.

12. Biogas:

  • Produced from organic waste; it is efficient compared to kerosene and dung cakes.
  • Gobar gas plants benefit farmers by providing energy and manure.

13. Tidal Energy:

  • Generated using oceanic tides with floodgate dams.
  • Potential sites: Gulf of Khambhat, Gulf of Kutch, Gangetic delta in Sunderbans.

14. Geothermal Energy:

  • Utilizes Earth’s internal heat.
  • High geothermal gradient areas: Parvati Valley (Himachal Pradesh), Puga Valley (Ladakh).

  • Twin strategies for sustainability:
    a. Energy conservation
    b. Increased use of renewable energy sources

3. Energy Efficiency in India:

  • India is among the least energy-efficient countries globally.
  • Judicious use of energy resources is critical due to their limited availability.

4. Citizen’s Role in Energy Conservation:
