<<–2/”>a href=”https://exam.pscnotes.com/5653-2/”>p>Energy is a vital component for the development and functioning of modern societies. It powers industries, homes, transportation, and virtually every aspect of human life. There are two primary categories of energy sources: conventional and non-conventional. Conventional sources of energy, also known as traditional or non-RENEWABLE ENERGY sources, have been used for a long time and are typically derived from fossil fuels like coal, oil, and natural gas. Non-conventional sources of energy, often referred to as renewable or alternative energy sources, include solar, wind, geothermal, and Biomass/”>Biomass energy. These sources are considered more sustainable and environmentally friendly compared to their conventional counterparts.
| Aspect | Conventional Sources of Energy | Non-Conventional Sources of Energy |
|---|---|---|
| Definition | Energy sources that have been traditionally used and are non-renewable. | Energy sources that are alternative, renewable, and more sustainable. |
| Examples | Coal, oil, natural gas, Nuclear Energy. | Solar, wind, geothermal, biomass, hydropower. |
| Availability | Limited and depleting over time. | Abundant and naturally replenished. |
| Environmental Impact | High pollution and greenhouse gas emissions. | Minimal environmental impact and low emissions. |
| Cost | Initially lower but increasing due to scarcity. | Higher initial Investment but decreasing costs with technology improvements. |
| Technology | Well-established and widely used. | Emerging technologies with ongoing advancements. |
| Sustainability | Unsustainable due to finite Resources. | Sustainable and renewable over the long term. |
| Energy Security | Vulnerable to geopolitical tensions and resource depletion. | Enhanced security with diverse and locally available sources. |
| Operational Efficiency | Generally high, but depends on resource availability. | Varies widely; improving with technological advancements. |
| Energy Density | High energy density (more energy per unit). | Lower energy density; larger installations needed for the same output. |

1. What are conventional sources of energy?
Conventional sources of energy are traditional, non-renewable sources such as coal, oil, natural gas, and nuclear energy that have been used for many years to produce energy.
2. What are non-conventional sources of energy?
Non-conventional sources of energy are renewable and alternative energy sources such as solar, wind, geothermal, biomass, and hydropower that are more sustainable and environmentally friendly.
3. Why are non-conventional sources of energy considered better for the Environment?
Non-conventional sources of energy produce minimal pollution, have lower greenhouse gas emissions, and have a lesser environmental impact compared to conventional sources.
4. What are the main disadvantages of conventional energy sources?
The main disadvantages include environmental pollution, finite resource depletion, Health risks, and geopolitical tensions arising from fossil fuel dependency.
5. How does energy density differ between conventional and non-conventional sources?
Conventional sources typically have a higher energy density, meaning they produce more energy per unit of fuel compared to non-conventional sources which have lower energy density and often require larger installations.
6. Can non-conventional sources of energy fully replace conventional sources?
While non-conventional sources have the potential to significantly reduce dependence on conventional sources, complete replacement may require substantial advancements in technology, Infrastructure-2/”>INFRASTRUCTURE, and storage solutions.
7. What are the economic implications of transitioning to non-conventional sources of energy?
Transitioning involves high initial costs but can lead to long-term Savings, job creation in new industries, and reduced geopolitical risks associated with fossil fuel imports.
8. How do conventional and non-conventional sources contribute to energy security?
Conventional sources are vulnerable to depletion and geopolitical issues, while non-conventional sources enhance energy security through diversity and local availability of resources.
9. What role does technology play in the utilization of non-conventional energy sources?
Technology is crucial for harnessing, storing, and efficiently utilizing non-conventional energy sources, and ongoing advancements are making these sources more viable and cost-effective.
10. What are the main challenges associated with non-conventional energy sources?
The main challenges include high initial investment costs, intermittency of sources like solar and wind, land and space requirements, and technological and scalability issues.
By understanding the differences, advantages, disadvantages, and similarities of conventional and non-conventional energy sources, we can make informed decisions about our energy future and work towards a more sustainable and environmentally friendly energy system.
