Based on Exhaustibility:
Renewable – Non-exhaustible
Based on renewability, resources can be classified as renewable resources and non-renewable resources.
- Once consumed, it can be renewed with the passage of time.
- (e.g.) Air, Water, Sunlight.
- Misuse of such resources can also limit its available quantity.
- So, they should be used wisely.
Non-renewable – exhaustible
- Limited natural resources
- They become exhausted after use, and the time they take to replace does not match the life cycle.
- (e.g.) Coal, petroleum, natural gas and other minerals.
- Non-renewable resources are either scarce or absent.
- We are constantly taking up several new researches to find new resources.
- Research is done to confirm whether a substance is a resource or not.
- He tries to harness it and also searches the regions where it may be found.
- They are potential resources.
- Wind energy is one such example.
- The places where wind energy can be utilized are still unknown.
