MP Board · Class 10 · Social Science · Geography: Minerals and Energy ResourcesDifferentiate between conventional and non-conventional sources of energy. Give suitable examples of each and explain their significance in the modern world.

Introduction to Energy Sources\nEnergy is a fundamental requirement for the economic development of any country. Every sector of the national economy—agriculture, industry, transport, and domestic—needs inputs of energy. Energy resources are broadly classified into two categories: conventional and non-conventional sources.

1. Conventional Sources of Energy\nConventional sources of energy are those which have been in common use for a long time. Most of these are exhaustible non-renewable resources, meaning once they are consumed, they cannot be replaced easily.

• Examples: Coal, petroleum, natural gas, and electricity (both hydel and thermal).
• Significance & Drawbacks: They have powered the Industrial Revolution and continue to meet the bulk of global energy demands. However, their excessive usage leads to environmental pollution, greenhouse gas emissions, and depletion of natural reserves.

2. Non-Conventional Sources of Energy\nNon-conventional sources of energy are relatively new sources that are generally renewable, inexhaustible, and eco-friendly. With technological advancements, these sources are gaining immense popularity worldwide.

• Examples: Solar energy, wind energy, tidal energy, geothermal energy, and biogas.
• Significance & Advantages: They are inexhaustible, cause little to no environmental pollution, and help in reducing dependence on fossil fuels. They are particularly useful for decentralized power generation in remote and rural areas.

Detailed Differences

• Availability: Conventional sources are finite and depleting fast, whereas non-conventional sources are abundant and renewable.
• Environmental Impact: Conventional sources are major contributors to global warming and air pollution; non-conventional sources are clean and green.
• Cost & Technology: Conventional energy relies on established extraction and burning technologies. Non-conventional energy often requires high initial capital investment for advanced technology.

Conclusion\nIn the modern world, transitioning from conventional to non-conventional energy sources is imperative for achieving sustainable development and combating climate change.
