Conventional and Non-Conventional Resources of Energy
What are Conventional Resources?
Conventional resources are traditional energy sources that have been used for a long time. They include:
- Fossil Fuels: Coal, oil, and natural gas.
- CNG (Compressed Natural Gas): Often used for vehicles.
Characteristics:
- Non-Renewable: They take millions of years to form and are finite.
- Environmental Impact: Burning these fuels releases greenhouse gases, contributing to pollution and climate change.
What are Non-Conventional Resources?
Non-conventional resources are newer and more sustainable energy sources. Examples include:
- Solar Energy: Harnessed from sunlight.
- Wind Energy: Generated using wind turbines.
- Hydro Energy: Produced from flowing water.
Characteristics:
- Renewable: They can be replenished naturally and are considered sustainable.
- Eco-Friendly: These sources produce little to no pollution, making them better for the environment.
Key Differences
| Feature | Conventional Resources | Non-Conventional Resources |
|---|---|---|
| Examples | Coal, oil, natural gas | Solar, wind, hydro |
| Renewability | Non-renewable | Renewable |
| Environmental Impact | High pollution and greenhouse gases | Minimal pollution |
| Availability | Limited and depleting | Abundant and sustainable |
In summary, while conventional resources are traditional and finite, non-conventional resources offer renewable options that are more environmentally friendly.

Gases that trap heat in the atmosphere are called greenhouse gases. The atmosphere that raise the surface temperature of planets such as the Earth distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect.The Earth is warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by greenhouse gases. Without greenhouse gases in therather than the present average of 15 °C (59 °F). atmosphere, the average temperature of Earth’s surface would be about −18 °C (0 °F),
Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials.Carbon dioxide is removed from the atmosphere it is absorbed by the plants as a part of biological carbon cycle.
Methane (CH4): Methane is emitted during the production and transport of coal, natural gas, and oil.
Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural, land use, and industrial activities; combustion of fossil fuels and solid waste; as well as during treatment of wastewater.
Each gas’s effect on climate change depends on three main factors.
Human activities increase the carbon dioxide by over 50%.It cause global warming.
