Q. How can India achieve energy independence through clean technology by 2047? How can biotechnology play a crucial role in this endeavour?
Introduction:
Energy independence by 2047 aligns with India’s net-zero vision, requiring a transition to clean, indigenous, and technology-driven energy systems.
Pathways for Energy Independence through Clean Technology
1. Renewable Energy Expansion
- Solar, wind, hydro → target 500 GW non-fossil capacity by 2030
- Rooftop solar, decentralised grids
2. Green Hydrogen Economy
- National Green Hydrogen Mission
- Use in refining, fertilisers, heavy transport
3. Electrification of Mobility
- EV push (FAME scheme)
- Reduce oil import dependence (~85% crude imported)
4. Energy Storage Solutions
- Battery storage (Li-ion, Na-ion)
- Pumped hydro storage for grid stability
5. Nuclear & Emerging Tech
- Expansion of nuclear energy
- Long-term: fusion (ITER participation)
6. Energy Efficiency
- PAT scheme, LED (UJALA) success
- Demand-side management
7. Domestic Manufacturing
- Solar PV, batteries under PLI schemes
- Reduce import dependence (China-centric supply chains)
Role of Biotechnology in Energy Independence
1. Biofuels Production
- Ethanol blending (E20 target by 2025–26)
- 2G ethanol from agri-residue (stubble → fuel)
2. Advanced Bioenergy
- Algae-based biofuels (high yield, low land use)
- Biodiesel from non-edible oils
3. Waste-to-Energy
- Biogas, compressed biogas (CBG) under SATAT
- Municipal/agri waste → energy + circular economy
4. Industrial Biotechnology
- Enzymes improving biofuel efficiency
- Biorefineries producing fuels + chemicals
5. Carbon Capture & Utilisation
- Microbial carbon capture technologies
- Bio-sequestration (enhanced carbon sinks)
6. Sustainable Agriculture Link
- Biofertilisers reducing fossil-fuel-based inputs
- Crop residue utilisation → energy feedstock
Supporting Policy & Institutional Framework
- NITI Aayog: roadmap for energy transition
- National Bio-Energy Mission
- National Policy on Biofuels (2018, amended)
- International Solar Alliance (ISA)
Challenges
- Intermittency of renewables
- High initial costs (storage, hydrogen)
- Technology gaps in advanced biofuels
- Land & water constraints
Way Forward
1. Integrated Energy Strategy
- Mix of renewables + bioenergy + storage
2. R&D Push
- Public-private investment in biotech & clean tech
3. Infrastructure Development
- Grid modernisation, EV charging, bio-refineries
4. Behavioural & Policy Support
- Incentives, carbon pricing, regulatory stability
Conclusion:
By synergising clean technologies with biotechnology innovations, India can achieve sustainable energy independence while ensuring economic growth and environmental security by 2047.
