UPSC Previous Year Question | Mains GS3 | 2025

How can India achieve energy independence through clean technology by 2047? How can biotechnology can play a crucial role in this endeavour? (Answer in 150 words)

Answer

Introduction

Introduction

Energy independence requires reducing imported fossil fuels while expanding domestic, reliable and affordable clean-energy systems.

Clean Technology

Clean-technology pathway

  • Scale solar, wind, hydro, nuclear and green hydrogen with domestic manufacturing.
  • Modernise grids through storage, transmission, demand response and distributed renewable systems.
  • Electrify transport, industry and cooking; improve building and appliance efficiency.
  • Promote recycling, critical-mineral security, R&D and just transition for affected workers.

Biotechnology

Biotechnology’s role

  • Advanced biofuels from agricultural residues, algae and waste can decarbonise hard-to-electrify transport.
  • Biogas and biomethane convert organic waste into energy and reduce methane emissions.
  • Industrial enzymes, synthetic biology and bio-based materials reduce process energy and fossil inputs.
  • Biofertilisers and climate-resilient crops lower agriculture’s energy and emissions intensity.
