MP Board · Class 10 · Social Science · Geography: Minerals and Energy ResourcesDistinguish between conventional and non-conventional sources of energy. Give examples of each and explain why there is an urgent need to promote non-conventional energy resources in India.

Difference between Conventional and Non-Conventional Sources of Energy

\nEnergy is fundamental for the economic development of any nation. Sources of energy can be broadly classified into conventional and non-conventional categories based on their availability, usage, and environmental impact.

1. Conventional Sources of Energy\nConventional sources of energy are those that have been in common use for a long time. Most of these are exhaustible non-renewable resources, except for firewood and hydel power. Once depleted, they cannot be quickly replenished.

• Examples: Coal, petroleum, natural gas, firewood, cattle dung cake, and electricity (hydel and thermal).
• Characteristics: They cause severe environmental pollution (air pollution, greenhouse gas emissions), require heavy capital investment for extraction and transportation, and are unevenly distributed.

2. Non-Conventional Sources of Energy\nNon-conventional sources of energy, also known as renewable sources, have been developed in recent decades due to advanced technology and growing environmental concerns. They are inexhaustible, eco-friendly, and continuously replenished by natural processes.

• Examples: Solar energy, wind energy, tidal energy, geothermal energy, biogas, and atomic/nuclear energy.
• Characteristics: They are pollution-free, have low running costs once installed, are abundantly available in nature, and promote decentralized energy generation.

Urgent Need to Promote Non-Conventional Energy Resources in India\nIndia is a rapidly developing nation with a surging energy demand driven by industrialization, urbanization, and population growth. Promoting non-conventional energy is crucial due to the following reasons:

• Depletion of Fossil Fuels: Conventional resources like coal and petroleum are finite and fast depleting. Shifting to renewables ensures long-term energy security.
• Environmental Protection: Burning fossil fuels releases harmful carbon emissions contributing to global warming and climate change. Non-conventional sources are clean and sustainable.
• Import Dependency: India imports a massive share of its crude oil requirements. Developing domestic renewable resources reduces this economic and strategic vulnerability.
• Rural Electrification: Decentralized sources like solar and biogas can easily power remote, hilly, and isolated rural areas where extending conventional grid lines is economically unviable. \nIn conclusion, transitioning towards non-conventional energy resources is not just an alternative choice for India, but an absolute necessity for sustainable future growth.
