Ethanol Blending β Green Fuel or Hidden Cost? ππ±
In 2025, India hit a big fuel milestone β 20% ethanol in petrol (E20). On paper, itβs a triple win: cleaner fuel, lower oil imports, and better farmer incomes.
Ethanol, made from sugarcane or surplus grains, burns cleaner than petrol, cutting carbon monoxide emissions by up to 50%. Between 2014 and 2025, it saved India βΉ1.4 lakh crore in foreign exchange and put βΉ92,000 crore into farmersβ pockets. For sugar mills, it turned excess cane into profit.
But hereβs the catch. Ethanol gives 30% less energy than petrol, meaning lower mileage β a recent survey found over 10% drop for petrol vehicles. It also absorbs moisture, causing corrosion in engines. On the farm side, sugarcane-based ethanol is water-hungry, draining groundwater in drought-prone states like Maharashtra. And when maize is diverted to ethanol, poultry and cattle feed prices spike.
Infrastructure isnβt perfect either β ethanol supply is concentrated in a few states, storage is half of whatβs needed, and interstate movement still faces hurdles. Yet, India plans to go E30 by 2030 and push βflex-fuelβ cars running on blends as high as E85.
