Minerals and Energy Resources

  • Haban observes vehicles and trains made of metals (iron, aluminum) powered by engines.
  • Daily life relies on various metal objects made from extracted minerals.
  • Earth's crust contains minerals from which metals are extracted.
  • Minerals are critical components in daily life - from tiny pins to large structures, machinery, and vehicles.
  • Food also contains minerals.
  • Toothpaste uses abrasive minerals (silica, limestone, aluminum oxide) and fluoride (from fluorite) for cleaning.
  • Titanium oxide (from rutile, ilmenite, and anatase) gives toothpaste its white color.
  • Mica provides sparkle in some toothpastes.
  • Toothpaste tubes and brushes use plastics derived from petroleum.

  • Copper: used in electrical wires and other industrial applications, reserves in Rajasthan, Madhya Pradesh, and Jharkand.
  • Bauxite: used in aluminum production, high resources in Odisha and Gujarat.
  • Coal: Important fuel source in India in various forms, notably the Damodar Valley in Jharkhand, Chhattisgarh.

Energy Resources

  • Conventional (Coal, petroleum, natural gas): Used in energy production.
  • Non-conventional (Solar, wind, hydropower, geothermal): Renewable energy sources.
  • Coal is India's most abundant fossil fuel, utilized for power generation, industrial use, and domestic purposes.
  • Petroleum is used in industries and for transportation.
  • Natural gas is becoming an important energy source for domestic use, industry and transportation.
  • Solar energy: India is a tropical country with significant solar resources.
  • Wind energy: India has large-scale potential for wind energy, notably in Tamil Nadu, Gujarat, and Karnataka.
