Points to Remember:
- Conventional energy sources are those that have been used for a long time and are readily available.
- Renewable energy sources are replenished naturally and are sustainable.
- Non-renewable energy sources are finite and will eventually be depleted.
Introduction:
The question asks to identify a conventional source of energy from the given options. Conventional energy sources are traditionally used energy sources that have been harnessed for centuries to power industries, transportation, and homes. These sources are often contrasted with newer, renewable energy sources like solar and wind power. The key difference lies in their sustainability and impact on the environment. While renewable sources are replenished naturally, conventional sources are finite and often contribute significantly to pollution.

Defining Conventional Energy Sources:
Conventional energy sources are primarily fossil fuels (coal, oil, and natural gas) and nuclear energy. These sources have been the backbone of global energy production for decades, driving industrialization and economic growth. However, their use comes with significant environmental and social costs.
Analyzing the Options:
- (A) Wind energy: Wind energy is a renewable energy source, harnessed through wind turbines. It is not considered a conventional energy source.
- (B) Solar energy: Solar energy is another renewable energy source, utilizing sunlight to generate electricity. It is a relatively recent addition to the energy mix and is not considered conventional.
- (C) Coal: Coal is a fossil fuel, a readily available and historically significant energy source. It has been extensively used for electricity generation and industrial processes for centuries. Therefore, coal is a clear example of a conventional energy source.
- (D) Nuclear energy: Nuclear energy utilizes nuclear fission to generate electricity. While a relatively modern technology, its use is widespread and established, making it a conventional energy source.
Comparison of Conventional and Renewable Energy Sources:
| Feature | Conventional Energy (e.g., Coal) | Renewable Energy (e.g., Solar) |
|—————–|———————————|———————————|
| Availability | Finite, depleting resources | Continuously replenished |
| Environmental Impact | High pollution, greenhouse gases | Low pollution, sustainable |
| Cost | Relatively low (initially) | Higher initial investment, lower running costs |
| Sustainability | Unsustainable | Sustainable |
Conclusion:
In summary, while both coal and nuclear energy are conventional sources, the question specifically asks for a conventional source. Coal, due to its long history of use and widespread application, is a clear and readily identifiable example of a conventional energy source. Therefore, the correct answer is (C) Coal. However, it’s crucial to acknowledge the environmental consequences associated with the continued reliance on conventional energy sources. A transition towards a more sustainable energy mix, incorporating renewable sources, is essential for mitigating climate change and ensuring long-term energy security. This transition requires strategic policy interventions, investments in renewable energy technologies, and a global commitment to reducing greenhouse gas emissions. By embracing sustainable practices and prioritizing environmental protection, we can pave the way for a future powered by clean and renewable energy sources, ensuring a healthier planet for generations to come.
