खालीलपैकी कोणता भारतातील अपरंपरागत उर्जास्त्रोत नाही ?

The correct answer is Option B (Agricultural waste).

Key Points:
• The correct option is (2).
• Classification of Energy Sources:
• Non-conventional (renewable) energy sources are clean, inexhaustible, and modern alternative sources developed primarily in recent decades. These include:
• Solar energy (सौर ऊर्जा)
• Wind energy (पवन ऊर्जा)
• Tidal and Wave energy (भरती-ओहोटी ऊर्जा)
• Geothermal energy (भू-औष्णिक ऊर्जा)
• Conventional sources are traditional energy forms in long-standing usage. Agricultural waste, crop residue, animal dung, and fuelwood have historically been classified in traditional rural energy audits as conventional biomass/combustion energy.
• As per the official MPSC key, agricultural waste is recognized as not belonging strictly to modern non-conventional energy sources.
• Key Takeaway: Solar, wind, and tidal are non-conventional renewable energy sources, whereas agricultural waste is treated as traditional/conventional.
