Ethanol Blending Is Dividing India's Auto Sector — Here's Why EVs Are Winning the Reliability Race

India's ethanol blending policy is back in the headlines — and not for the right reasons.

A recent report by India Today dropped a startling figure: producing just 1 litre of ethanol consumes up to 10,000 litres of water. The report came shortly after the government released a public policy document seeking opinions on pushing ethanol blending as high as 80–100%. The internet erupted. Old controversies resurfaced. And a minister called critics "anti-nationals."

We believe that understanding complex policy intersections — energy, agriculture, water, and technology — is essential for businesses and citizens navigating India's rapidly evolving landscape. So let's break this down clearly, one layer at a time.

What Is Ethanol Blending?

Ethanol is a type of alcohol produced from crops like sugarcane, corn, and surplus grains. Instead of being consumed as a beverage, it is refined into fuel and mixed with regular petrol before it reaches your vehicle.

This blended fuel burns cleaner than pure petrol. Because it comes from crops grown by farmers rather than extracted from underground oil reserves, it is widely described as a more renewable and eco-friendly energy source.

Ethanol blending simply refers to the practice of mixing this plant-based ethanol with standard petrol. When you fill your tank today, you may already be running on a blend — E10 means 10% ethanol and 90% petrol; E20 means 20% ethanol and 80% petrol.

The logic behind it is straightforward: cleaner fuel, reduced dependence on imported crude oil, and a new market for Indian farmers. In theory, it is like giving conventional fuel a greener upgrade without overhauling how vehicles work.

Why Did India Adopt Ethanol Blending?

Tackling Food Surplus in Government Warehouses

The Government of India amended its National Biofuel Policy in 2022 to introduce E20 fuel, partly as a solution to a growing problem: excess food accumulation.

Under the Minimum Support Price (MSP) scheme, the government guarantees purchase of around 22 crops including rice and wheat through the Food Corporation of India (FCI). Over time, this created a significant overstocking issue. While welfare schemes distribute roughly 40 lakh metric tonnes of rice annually, the FCI was procuring close to 310 lakh metric tonnes. Ethanol production offered a practical outlet for this surplus.

A New Market for Farmers

For farmers, ethanol policy opened an alternative revenue channel beyond APMC mandis. With no middlemen involved and a government-backed demand, it offered the possibility of better and more predictable income from their produce.

Reducing India's Import Bill

India is one of the world's largest importers of crude oil. Reducing petrol consumption through blending can ease the import burden, improve the balance of payments, and strengthen the broader economy over time.

The Real Problem: What the Controversy Is Actually About

The Hidden Water Cost of Ethanol

What sounds like a green policy comes with a significant hidden cost — water.

Anjal Prakash, a contributing author to the International Panel on Climate Change, stated that ethanol blending can worsen India's water crisis because the primary raw materials — sugarcane and increasingly maize — are among the most water-intensive crops to grow and process.

The government allocated 52 lakh tonnes of rice for ethanol production in 2024–25 and is now targeting 90 lakh tonnes in 2025–26. More concerning, this additional rice supply is reportedly being drawn in part from the share of broken rice that was previously distributed to poor households under the Public Distribution System — with that share proposed to fall from 25% to 10%.

The demand created by the ethanol policy is effectively channelling water-hungry crops — rice, sugarcane, maize — away from food systems and toward oil refineries. The policy, by simultaneously creating demand-side incentives and MSP-backed supply-side support, is constructing the conditions for large-scale, policy-induced water scarcity in already-stressed states like Maharashtra and Punjab.

Do We Even Have the Surplus?

Last year, India became a net corn importer for the first time in several years. The push toward corn-based ethanol had diverted maize from the poultry and animal feed sectors, exposing a critical supply gap.

The government's response has been to incentivise expansion of corn cultivation. Maize acreage increased from 83 lakh hectares to approximately 92 lakh hectares during the current kharif season due to stronger prices and ethanol demand. In other words, India did not have the agricultural surplus to support high ethanol blending — it is actively engineering one. If water scarcity results from this strategy, it will not be an accident. It will be a policy outcome.

The Political Controversy

No discussion of this policy is complete without acknowledging the political dimension. Nikhil Gadkari — son of Union Minister for Road Transport and Highways, Nitin Gadkari — serves as the Managing and Executive Director of CIAN Agro Industries & Infrastructure Limited, a company directly involved in manufacturing green ethanol.

When news agency Facttious questioned the minister about the water usage loophole in the policy, he responded by calling critics "anti-nationals." This response, combined with his son's commercial interests in the sector, has drawn widespread accusations of nepotism and significantly politicised what is genuinely an important environmental and economic debate.

The Smarter Path Forward: Why EVs Offer a More Sustainable Solution

Green Tree Digital's perspective is grounded in long-term systems thinking. Here is why electric vehicles represent a structurally sounder alternative to high-ratio ethanol blending.

Breaking the MSP–Overstocking Cycle

India's ethanol strategy is increasingly entangled with surplus food procurement under the MSP system. This creates a policy loop where excess agricultural production is indirectly encouraged to feed fuel demand. Electric vehicles require no food crops as an energy source, freeing agricultural policy to prioritise food security, rural nutrition, and genuine crop diversification.

EVs and E20 Are Not Mutually Exclusive

A balanced coexistence is more realistic and responsible than pushing ethanol toward E85 or E100. Maintaining E20 blending still gives farmers an alternative market outside traditional APMC mandis. But scaling EV adoption relieves agriculture from shouldering India's entire fuel transition — a burden it was never designed to carry.

Reducing Import Dependency Without Permanent Farm Pressure

EVs dramatically reduce crude oil imports. Critics often raise the concern of battery material dependency on China, but India has substantial reserves of rare earth and battery materials in Jammu and Kashmir, Odisha, Tamil Nadu, Karnataka, and Kerala — and active plans to develop these corridors. Unlike ethanol, EV infrastructure does not consume agricultural land and freshwater every single year as a recurring cost.

No Hidden Water Footprint

The most damaging criticism of the ethanol policy is its water cost — reportedly over 10,000 litres of water per litre of ethanol produced. Electric vehicles carry no such hidden environmental liability. And as India has already crossed 50% installed electricity generation capacity from non-fossil fuel sources, EVs will increasingly run on renewable energy rather than coal, making their environmental case stronger with each passing year.

The Balanced View

E20 blending can function as a sensible transitional policy — it reduces emissions modestly, supports farmers, and utilises genuine surplus. But scaling ethanol blending to E85 or E100 risks triggering food insecurity, water stress, and political capture of agricultural policy.

Electric mobility can absorb India's long-term fuel transition more efficiently, with fewer structural trade-offs and significantly less political baggage. At Green Tree Digital, we see EV adoption as not just an environmental choice but a strategic one — more stable, more scalable, and built on a foundation that does not compete with the food on your plate.

Frequently Asked Questions:

1. What is ethanol blending and how does it work in India?

Ethanol blending means mixing plant-derived ethanol with standard petrol before it reaches your fuel tank. In India, blends like E10 (10% ethanol) and E20 (20% ethanol) are currently in use. The policy was formalised under the National Biofuel Policy 2022, with the goal of reducing crude oil imports, cutting vehicle emissions, and creating additional income for farmers growing crops like sugarcane, maize, and rice.

2. Why is India's ethanol blending policy controversial in 2025–26?

The policy has drawn criticism on multiple fronts — most notably, the enormous water consumption required to grow ethanol crops like sugarcane and rice. A report citing IPCC author Anjal Prakash highlighted that producing 1 litre of ethanol can consume up to 10,000 litres of water. The diversion of rice meant for poor households under the PDS, combined with perceived conflicts of interest involving a minister's family, has intensified public scrutiny.

3. How does ethanol blending affect India's water crisis?

Sugarcane, maize, and rice — the primary crops used for ethanol production — are among the most water-intensive to cultivate and process. As the government scales ethanol targets (from 52 lakh tonnes of rice in 2024–25 to 90 lakh tonnes in 2025–26), the increased agricultural demand risks deepening water scarcity in already water-stressed regions like Maharashtra and Punjab. Crucially, this would be policy-induced scarcity rather than a naturally occurring one.

4. Are electric vehicles actually better than flex fuel or ethanol-blended vehicles?

For long-term sustainability, yes. EVs eliminate the recurring water and land footprint of crop-based fuel production, reduce dependence on both crude oil imports and MSP-driven agriculture, and become progressively cleaner as India's electricity grid shifts toward renewables. India has already crossed 50% non-fossil fuel installed power capacity, meaning EVs today are substantially cleaner than they were even five years ago.

5. Can India pursue both EV adoption and ethanol blending simultaneously?

Yes — and that is likely the most pragmatic approach. Maintaining E20 blending supports farmers and provides a useful transitional policy, while EV adoption gradually reduces the scale of ethanol demand required. The danger lies in pushing blending to E85 or E100, which would require sustained, large-scale diversion of food crops and water resources in ways that are difficult to justify given the availability of cleaner alternatives.

6. What is Green Tree Digital's position on India's energy transition?

Green Tree Digital believes that India's energy and transport transition must be grounded in systems thinking — accounting not just for emissions, but for water, food security, and long-term economic resilience. E20 as a transitional bridge makes sense. High-ratio ethanol blending as a permanent strategy does not. Scaling electric mobility, backed by India's growing renewable energy capacity and domestic battery material reserves, offers the most sustainable and politically neutral path forward.
