Q. India achieved its E20 target five years ahead of schedule. Critically examine the trade-offs between biofuel-driven energy transition and food/water security concerns linked to feedstock diversion. (15 marks, 250-350 words)

Ethanol blending rose from under 1.5% in 2013-14 to 20% in 2025-26, meeting the E20 target five years ahead of the 2030 deadline [1]. This strengthens energy security, but scaling blending on sugarcane and food-grain feedstock carries food and water costs that must be weighed against those gains.

Gains from the biofuel transition - Energy security: ethanol substitutes imported crude, saving over ₹1.4 lakh crore in foreign exchange and cutting import dependence [1]. - Farm economy: assured offtake by public OMCs under a Cabinet-approved pricing mechanism converts surplus cane and grain into steady rural income [2]. - Environment: E20 is claimed to lower lifecycle carbon emissions by nearly 40% against pure petrol, aiding India's net-zero pathway [1]. - Capacity build-up: distillery capacity expanded from the 500-600 crore litre requirement of 2021 to roughly 1,200 crore litres available today [2].

Food and water security concerns - Water intensity: NITI Aayog estimated about 2,860 litres of water per litre of cane-based ethanol [3] — a heavy draw in already water-stressed Maharashtra, UP and Karnataka. - Feedstock diversion: the National Policy on Biofuels, 2018 opened maize and surplus grain to ethanol [2], creating fuel-versus-food and feed competition that can transmit into food inflation. - Cropping distortion: guaranteed ethanol demand incentivises water-guzzling cane monoculture over pulses and millets, weakening dietary diversity and soil health. - Equitable gains: benefits concentrate in irrigated belts and large distilleries, bypassing rainfed farmers.

Assessment: the trade-off is manageable, not fatal. NITI Aayog itself recommended incentivising less water-intensive feedstocks and second-generation ethanol from crop residue [3], a direction supported by PM JI-VAN Yojana.

On balance, E20 is a net gain for energy security that has outpaced its ecological safeguards rather than replaced them. Anchoring further blending in a water-and-food audit, feedstock diversification toward 2G and maize, and transparent public communication [4] would let India pursue SDG-7 on clean energy without conceding SDG-2 on zero hunger.
