Revision summary
India still imports most of its crude, so 2047 independence means much lower import intensity, not a sealed border. Clean electricity from solar, wind, storage and nuclear, plus green hydrogen and efficiency, are the main path. Electric mobility cuts oil only if the grid is cleaner. Biotechnology helps through biogas, second-generation ethanol from residue, industrial enzymes and less energy-intensive farming. Fuel-from-food is a poor version of that biotech role.
Model answer
Introduction
India still imports most of its crude oil and a large share of gas. That is a strategic bill as well as a trade bill. Energy independence by 2047, the hundredth year of independence, cannot mean that no tanker docks. It can mean that electricity, cooking and a growing slice of mobility no longer live or die by a Gulf strait. Clean technology is the tool. Biotechnology is one under-sold branch of that tool.
Body
The 2047 path
Independence here is lower import intensity plus secure electrons. Solar and wind, already the cheapest new bulk power in many auctions, must scale with storage (batteries, pumped hydro). Nuclear gives firm power; small modular talk is still talk until steel is poured. Green hydrogen can enter fertiliser and refining, where India now uses grey hydrogen from gas. Efficiency — buildings, motors, a modal shift to rail — is the cleanest “source”. EVs cut oil if the grid is cleaner. Coal will linger in the 2030s; independence is a direction of travel, not a 2047 fairy tale of zero coal overnight.
Biotechnology’s role
Biotech is not a solar panel. It is life as a factory. Compressed biogas from cattle dung and crop waste (SATAT) replaces LPG and CNG molecules. Second-generation ethanol from agri-residue, if it actually works at scale, cuts petrol without eating food the way first-generation cane ethanol can. Enzymes make industrial processes run at lower heat. Algal or microbial routes to fuels and to carbon use are still mostly labs, but they belong in a 2047 story. GM and gene-edited crops that need less water or fertiliser cut the energy hidden in agriculture (fertiliser is gas-heavy). Biosafety and land-use ethics remain.
A biotech path that only burns food grain is a bad independence. A path that turns waste methane into a fuel and cuts fertiliser energy is a real one.
2047 will still see some oil. The test is whether India owns the electrons and the bio-molecules that can grow.

Conclusion
Energy independence by 2047 means a grid and a fuel mix that lean far less on imported oil and gas. Solar, wind, storage, nuclear and hydrogen do the heavy lifting. Biotechnology adds biogas, residue ethanol and lower-energy farming, if it uses waste more than food.

Will India stop importing oil in 2047?
Unlikely in full. The honest target is a much smaller oil share in a bigger economy.

Is ethanol blending energy independence?
It can cut the petrol bill. If the ethanol is from food crops, it can raise food and water stress.

Distinguish between the Human Development Index (HDI) and the Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?
Inclusive Growth
HDI combines life expectancy, education and GNI per capita into one average. India’s recent HDI is in the medium band, around 0.64, with a rank still in the 130s. IHDI reduces that score for inequality; India has often lost about thirty per cent of HDI to uneven shares. Inclusive growth needs the extra income and services to reach the bottom, which HDI alone can hide. IHDI is therefore the better national test, alongside the multidimensional poverty index.

What are the challenges before the Indian economy when the world is moving away from free trade and multilateralism to protectionism and bilateralism? How can these challenges be met?
Indian Economy
The world is shifting from a single WTO bargain toward tariffs, subsidies, friend-shoring and carbon border taxes. India’s risks are weaker Western demand, costly Chinese intermediates, technology denial and rupee shocks. Goods exports in textiles, engineering and chemicals are exposed. Responses include wider FTAs, PLI with quality, destination diversification, forex buffers and a defence of WTO rules. A large domestic market is India’s shock absorber, not a reason to close the border entirely.
Q3 · UPSC Mains 2025 · GS III · 10 marks
Explain the factors influencing the decision of the farmers on the selection of high value crops in India.
Crops, Irrigation and Marketing
High-value crops are horticulture, spices, flowers and similar bets that can earn more than grain. Farmers weigh expected price and a real buyer against water, labour, credit and the chance of a price crash. MSP rice and wheat remain the safer default where they exist. Horticulture tonnage in India has already overtaken foodgrain, which shows the shift is underway. Policy must cut risk with storage, processing and insurance, not only cheer diversification.
