Question

Differentiate between conventional and non-conventional energy resources. Explain their relevance in India's energy sector.

Ghissu Editorial · Accepted Answer

Conventional energy resources (coal, petroleum, natural gas, large hydro) are finite, high-emission and centralised, while non-conventional resources (solar, wind, biomass, small hydro, geothermal) are renewable, low-emission and can be decentralised. Coal still supplies about 69% of commercial electricity, but solar capacity rose from 3 GW (2014) to over 140 GW.

**Introduction**

India’s energy sector is transitioning to meet growing demand sustainably, guided by policies like the National Electricity Policy and climate commitments. This shift is crucial as India balances economic growth with environmental sustainability and energy security.

**Defining and Differentiating Energy Resources**

SKETCH: comparison | Conventional vs Non-Conventional Energy Resources
a: Conventional Energy Resources
b: Non-Conventional Energy Resources
- Origin :: Fossil fuels and large hydropower :: Solar, wind, biomass, geothermal
- Availability :: Finite and depletable :: Renewable and abundant
- Emissions :: High carbon emissions :: Low or zero emissions
- Infrastructure :: Large centralised plants :: Emerging, decentralised technologies

3. **Technological and Supply Differences**: Conventional energy relies on centralized, large-scale plants, while non-conventional energy enables decentralized generation, improving access in remote and rural areas.

**Relevance in India’s Energy Sector**

4. **Conventional Energy’s Role and Challenges**: Coal provides 69% of electricity; petroleum fuels transport; ==Andhra Pradesh’s coal plants and hydro stations like Srisailam Right Bank== show dependence; fossil fuel limits and pollution threaten security. Import dependence and environmental degradation further complicate reliance on conventional sources.  
5. **Non-Conventional Energy’s Expansion**: Solar capacity surged from 3 GW (2014) to 140 GW (2026); wind at 54.65 GW; ==PM Surya Ghar mission⟦1⟧ in Andhra Pradesh== connects rural homes to solar power; National Action Plan on Climate Change⟦2⟧ and PAT scheme incentivize renewables. These efforts reduce carbon intensity and create rural employment opportunities.

**Way Forward**

6. **Renewable Infrastructure and Decentralization**: Boost solar and wind in Andhra Pradesh’s coastal and Rayalaseema areas; expand off-grid renewables for rural electrification to reduce transmission losses and enhance energy access.  
7. **Innovation and Policy Support**: Invest in energy storage and fuel cells; align with National Green Hydrogen Mission; increase public awareness to encourage clean energy adoption and support sustainable growth.

**Conclusion**

Balancing conventional and non-conventional energy, backed by robust policies and local initiatives like those in ==Andhra Pradesh==, is key for India’s sustainable energy future and climate commitments. This integrated approach will ensure energy security while fulfilling global environmental responsibilities.
