Question

Distinguish between conventional and non-conventional sources of energy.

Hint:

Conventional energy → Non-renewable and polluting.
Non-conventional energy → Renewable and eco-friendly.

Answer 1

Concept: Energy resources are broadly classified into conventional and non-conventional sources based on their availability and environmental impact.
Step 1: sources of energy.
Conventional sources of energy are traditional energy resources that have been used for a long time. These sources are generally non-renewable and may cause environmental pollution. Examples include:
• Coal
• Petroleum
• Natural Gas

Step 2: -conventional sources of energy.
Non-conventional sources of energy are renewable and environmentally friendly sources that are increasingly being used as alternatives to conventional fuels. Examples include:
• Solar Energy
• Wind Energy
• Biogas

Step 3: differences.

• Conventional sources are limited and polluting, while non-conventional sources are renewable and cleaner.
• Conventional energy has been widely used for centuries, whereas non-conventional energy is being developed and promoted in recent times.

Final Answer:
Conventional sources of energy are traditional, mostly non-renewable energy resources such as coal and petroleum, while non-conventional sources are renewable and environmentally friendly sources such as solar and wind energy.
