India's crude oil consumption is estimated to be around 88.5% imported from abroad. This one single figure is also responsible for why ethanol has become both an economic strategy and fuel policy at the same time. In an economy like India, which depends so heavily on foreign oil, any increase in international prices of crude oil gets reflected in the foreign bill, in inflation and in the balance of payments. One of the few measures that India can undertake which will have a beneficial effect on all the three simultaneously is the blending of petrol with ethanol.

 

The statistics clearly indicate the rapid nature of the transition. The blending has gone up from less than 1.5% in 2013 to 20% in 2025. This is something that was expected to be accomplished by 2030 but was done five years earlier than planned. The production of ethanol went up from 38 crore liters in 2014 to 661.1 crore liters in June 2025 (Ministry of Petroleum and Natural Gas). It is also stated that India’s ethanol program has managed to save foreign exchange worth ₹1.9 lakh crore, reduce crude oil imports by 310 lakh metric tonnes, and also reduce carbon dioxide emissions by 93 lakh metric tonnes, while all fuel launches are subject to BIS tests to maintain safety. 

 

Rural India has been able to claim its rightful piece of the pie. The ethanol economy according to Ministry of Petroleum has been able to generate ₹1.66 lakh crore of income for farmers. The farmers who have been bearing the brunt of delayed payments for years due to the low periods of the sugar cycle, ethanol has provided an additional source to sell their crops. It has enabled sugar mills to get smoother cash flow as it used to be dependent only on the prices of sugar before. That is why the scheme has become an instance of rural development policy under the disguise of an energy policy. It now supports distilleries, transport operators, storage contractors, and a wide ancillary economy built around getting cane, grain, and ethanol to market.

 

More often overlooked is how fast capacity expansion has outpaced the mandate behind it. India now has approximately 500 distilleries for ethanol, and capacity has grown to be nearly twice as much as required by the current E20 blend. Distillery is an illiquid investment, and surplus capacity translates to increased fixed costs for a reduced quantity of goods produced compared to design capacity. As such, the only logical path forward is to increase the mandated ethanol blend, not because of efficiency and value-for-money from crops, but because it is the only way to ensure that hundreds of distilleries will stay afloat. Pricing trends for feedstock support this notion as maize-based ethanol has a procurement price of ₹71.86 per litre compared to ₹65.61 per litre of sugarcane and ₹60.32 per litre of rice.

The crop portfolio has progressed beyond the rhetoric of “feedstock diversification.” Maize provides nearly half of the nation’s ethanol production, damaged rice and other cereals contribute more than a fifth, while sugarcane, which the entire scheme has been designed for, contributes about one-quarter.

 

None of this comes free. This has been made clear by the experience of the 2023-24 season, during which drought conditions reduced the supply of sugar enough that the government felt compelled to put temporary limits on ethanol production from cane to preserve sugar supplies.

 

The problem of water is yet another consideration that is missing from the forex-saving headlines in this context. Sugarcane covers only about 3 percent of the total cropped area in India but uses around 20 percent of the nation’s irrigation water, and any further expansion of either sugarcane farming or water-hungry grain cultivation to meet ethanol production requirements poses additional strains on the groundwater in regions like Maharashtra and Karnataka, which are already suffering from stress on irrigation. There is also an energy content cost associated with this that is not often addressed in public discourse: ethanol contains considerably less energy content per liter than regular fuel, and this is something of a trade-off between mileage and energy security/rural incomes.

 

Industry analysts worry about capacity developed ahead of demand. India's distillery base has grown significantly, and some industry estimates say installed capacity exceeds the 20 percent blending rule. Distilleries are costly, illiquid assets, and idle capacity produces subtle institutional pressure to maintain raising the blending objective regardless of crop efficiency.

 

The third hidden cost is import substitution that results in creating yet another import need. Large-scale production of ethanol requires fertilizer, enzymes, and natural gas – some of them India imports from other countries, whereas increasing the cultivation area for maize and rice in order to produce ethanol would put pressure on areas producing pulses and edible oils, both of which categories are major import items for India. The programme may just be substituting import dependency on crude with fertilizers and edible oils.

 

The most promising way through this trade-off is second-generation ethanol, made from crop residue such as paddy straw and corn cobs rather than the grain or cane itself. India generates close to 500 million tonnes of agricultural residue a year, a large share of which is currently burned in fields and is a major contributor to the air pollution that blankets northern India every winter. Turning that residue into fuel converts a pollution problem into a feedstock, without asking the water table or the food buffer to absorb any more of the cost. This sidesteps the food-versus-fuel trade-off almost entirely.

 

International comparisons are worth using carefully here. Brazil has run ethanol blending for close to five decades, mandates around 27 percent today, and has flex-fuel vehicles in the large majority of its new car sales. The United States remains the world's largest producer, overwhelmingly from corn. 

 

None of this is in any way a case against ethanol. Reducing reliance on a single volatile, imported fuel is a legitimate hedge and rural India has a real, quantifiable share of the benefits. But a forex-savings number quoted in isolation, without the groundwater it drains, the food buffer it erodes in a bad monsoon, and the fertilizer and edible-oil imports it tacitly requires, is not the complete accounting of what the policy costs. The net import bill across oil, fertilizer and edible oil together would be a more useful figure to publish before committing to E27 or higher, rather than crude substituted. A water-use disclosure by feedstock would be desirable. That is the ledger a country with stressed groundwater in its major grain belts needs to see before the mandate climbs any higher.
