How can India achieve energy independence through clean technology by 2047? How can biotechnology can play a crucial role in this endeavour?
Approach · directive: “how”
What it asks · Lay out a clean-technology pathway that replaces imported fossil fuels by 2047, and show specifically where biotechnology fits in it.
The question has 2 parts — answer each
- Explain how India can achieve energy independence through clean technology by 2047 — the pathway
- Explain the crucial role biotechnology can play in this endeavour
Open with · India imports most of its crude oil and a good part of its gas; energy independence by 2047 means replacing those imports with domestic clean energy, not merely adding capacity.
Cover
- Renewables at scale — solar, wind, hybrids with storage — with 500 GW of non-fossil capacity by 2030 as a milestone.
- Green hydrogen (National Green Hydrogen Mission) to replace grey hydrogen in refineries and fertilisers and to decarbonise steel.
- Electric mobility and railways, battery storage and critical-mineral security; nuclear expansion including small modular reactors.
- Biotechnology — fuels: 2G ethanol from crop residue, compressed biogas (SATAT), sustainable aviation fuel; building on 20% ethanol blending.
- Biotechnology — process: engineered microbes and enzymes to cut the cost of cellulosic ethanol; algal biofuels; biological hydrogen production.
- Biotechnology — materials: bio-manufacturing of chemicals and plastics now made from petroleum, and biological carbon capture, under the BioE3 policy.
- Constraints: food–fuel trade-off, water use, feedstock logistics, scale-up finance and grid integration.
Close with · Energy independence will come from a portfolio — renewables and storage for power, hydrogen for industry, and biotechnology to turn biomass and waste into fuels and chemicals.

- The BioE3 policy (approved by the Cabinet in August 2024) names bio-based chemicals, biopolymers, enzymes and carbon capture among its thematic sectors — the bridge between biotechnology and clean energy. PIB, Cabinet — BioE3 (Biotechnology for Economy, Environment and Employment) Policy (24 August 2024) ↗“high value bio-based chemicals, biopolymers & enzymes; smart proteins & functional foods; precision biotherapeutics; climate resilient agriculture; carbon capture & its utilization”

India imports most of its crude oil and a large part of its gas; energy independence by 2047 means replacing those imports with domestic clean energy, not merely adding capacity.
Clean-technology pathway to 2047
- Renewables at scale: solar, wind and hybrids with storage, with 500 GW of non-fossil capacity by 2030 as the first milestone.
- Green hydrogen under the National Green Hydrogen Mission to replace grey hydrogen in refineries and fertilisers and to decarbonise steel.
- Electric mobility and railways, battery storage and critical-mineral security; nuclear expansion, including small modular reactors, for firm power.
- Demand side: efficiency standards, smart grids and pumped storage so that variable power becomes reliable power.
Where biotechnology fits
- Fuels: 2G ethanol from crop residue, compressed biogas under SATAT and sustainable aviation fuel, building on 20% ethanol blending.
- Process: engineered microbes and enzymes to cut the cost of cellulosic ethanol; algal biofuels; biological hydrogen production.
- Materials and carbon: bio-manufacturing of chemicals and plastics now made from petroleum, and biological carbon capture, under the BioE3 policy (2024).
- Constraints: the food–fuel trade-off, water use, feedstock logistics, scale-up finance and grid integration.
Energy independence will come from a portfolio — renewables and storage for power, hydrogen for industry, and biotechnology to turn biomass and waste into fuels and chemicals.
Written by Minimalist IAS from facts checked at source (how we verify) — a little fuller than exam length, so every part of the question is covered; in the hall, keep the structure and trim the detail. UPSC publishes no model answers: compare your structure and coverage with this, then write your own.
