CBSE · Class 10 · Social Science · Geography: Minerals and Energy ResourcesDifferentiate between conventional and non-conventional sources of energy. Explain the significance of promoting non-conventional energy resources in India.

Difference Between Conventional and Non-Conventional Sources of Energy

\nEnergy resources are categorized into two primary types based on their usage, origin, and renewability:

1. Conventional Sources of Energy:

   • Definition: These are traditional sources of energy that have been in common use for a long time and are mostly non-renewable.
   • Examples: Firewood, cattle dung cake, coal, petroleum, natural gas, and electricity (both thermal and hydel).
   • Characteristics: They are exhaustible except for hydel power, cause high levels of environmental pollution, and require heavy capital investment for extraction and processing.

2. Non-Conventional Sources of Energy:

   • Definition: These are modern, renewable sources of energy that have been developed recently as alternatives to exhaustible fossil fuels.
   • Examples: Solar energy, wind energy, tidal energy, geothermal energy, biogas, and atomic/nuclear energy.
   • Characteristics: They are inexhaustible, eco-friendly, sustainable, and have lower recurring costs once the installation is complete.

Significance of Promoting Non-Conventional Energy in India

• Abundant Availability: India is a tropical country blessed with abundant sunlight, vast coastal lines for wind and tidal energy, and agricultural waste for biomass.
• Energy Security: Over-reliance on imported crude oil strains India's economy; non-conventional sources reduce dependence on foreign fossil fuels.
• Environmental Protection: They produce clean energy with negligible greenhouse gas emissions, helping India meet its international climate commitments.
• Rural Development: Decentralized systems like solar lighting and biogas plants uplift rural economies by providing reliable power for domestic cooking and agricultural pumping.
