Solution
Renewable sources:
- These are the sources from which energy can be obtained continuously over a long period of time.
- They are non-conventional sources.
- These are the natural sources that will never get exhausted.
- These sources can be regenerated.
- Examples: Solar energy, wind energy, hydro-energy, geothermal energy, and nuclear energy.
Non-renewable sources:
- These are the sources from which energy can not be continuously obtained over a long period of time.
- They are conventional sources.
- These are natural sources, which would soon deplete.
- These sources cannot be regenerated.
- Examples: Coal, petroleum, and natural gas.
