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

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.
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.
Non-Conventional Energy’s Expansion
Solar capacity surged from 3 GW (2014) to 140 GW (2026); wind at 54.65 GW; PM Surya Ghar mission1 in Andhra Pradesh connects rural homes to solar power; National Action Plan on Climate Change2 and PAT scheme incentivize renewables. These efforts reduce carbon intensity and create rural employment opportunities.
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.
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.
