Differentiate between conventional and non-conventional sources of energy with examples.

Difference between conventional and non-conventional sources of energy:

1. Conventional sources are mostly non-renewable sources of energy while non-conventional sources are renewable.

2. Conventional sources are not all sustainable in the long run while non-conventional sources are sustainable.

3. Example of conventional sources: Coal, Petroleum, Natural Gas

Example of non-conventional sources: Solar energy, Wind Power, Biogas

Explanation: Non-conventional sources of energy are more energy efficient, cost efficient as well as the best for sustainable development.
