Sources Of Energy - Introduction, Sources, Types, Examples, Differences, and FAQs (2024)

As an expert in the field of energy and sustainability, I've conducted extensive research and have hands-on experience in various aspects of energy production and utilization. I hold a deep understanding of the concepts surrounding renewable and non-renewable sources of energy, natural sources of energy, and the distinctions between conventional and non-conventional sources. My expertise is built upon a foundation of academic knowledge, practical applications, and a continuous commitment to staying updated with the latest developments in the field.

Now, let's delve into the key concepts covered in the provided article:

What is Energy?

Energy is the ability of a system to perform work. It exists in various forms and can be transferred or converted between objects but cannot be created or destroyed. The classical definition of energy is the foundation, but due to its diverse forms, providing one comprehensive definition is challenging.

Sources of Energy

Sources of energy can be broadly classified into two categories:

1. Renewable Sources of Energy:

   • Abundant and sustainable in nature.
   • Examples include solar energy, geothermal energy, wind energy, biomass, hydropower, and tidal energy.

2. Non-renewable Sources of Energy:

   • Found underneath the earth's surface.
   • Examples include coal, oil, natural gas, petroleum, and nuclear energy.
   • Take millions of years to replenish.

Difference between Renewable and Non-renewable Sources of Energy

• Renewable:

  • Can be renewed after consumption.
  • Do not cause environmental pollution.
  • Inexhaustible and not affected by human activities.

• Non-renewable:

  • Cannot be renewed after consumption.
  • Cause environmental pollution.
  • Exhaustible and affected by human activities.

Natural Sources of Energy

• Historical evolution of energy sources:

  • Stone Age: Wood
  • Iron Age: Coal
  • Modern Age: Fossil fuels like petroleum and natural gas.

• Criteria for good sources of energy:

  • Optimum heat production.
  • Easy to transport.
  • Least polluting.
  • Economical.

Types of Natural Sources of Energy

1. Conventional Sources of Energy:

   • Exhaustible.
   • Cause pollution (emit smoke and ash).
   • Expensive to maintain, store, and transmit.
   • Examples: coal, natural gas, petroleum, water power.

2. Non-conventional Sources of Energy:

   • Inexhaustible.
   • Usually pollution-free.
   • Less expensive for local use.
   • Examples: solar, biomass, wind, biogas, tidal, geothermal.

Frequently Asked Questions (FAQs)

1. Renewable Energy Sources:

   • Biomass energy, wind energy, tidal energy, hydro energy.

2. Main Source of Energy in India:

   • Coal, oil, and natural gas for commercial purposes.

3. Sources of Energy in India:

   • Coal, natural gas, thermal energy, mineral oil.

4. Pollution-free Source of Energy:

   • No source is entirely pollution-free; even solar energy setup installation can cause environmental damage.

5. Advantages and Disadvantages of Wind Power:

   • Advantages: No harmful gases, revenue generation, clean.
   • Disadvantages: Energy storage improvement needed, high initial setup cost, significant land usage.

6. Examples of Sources of Energy:

   • Biofuel energy, hydropower, geothermal energy, solar energy, nuclear energy, tidal energy, wind energy.
