Every time you fill up your car or scooter in India today, there’s a good chance a portion of that fuel did not come from crude oil at all. It came from a field. As the country pushes hard to blend ethanol into petrol and biodiesel into diesel, a difficult question sits at the centre of this clean-energy transition: when farmland and crops are used to make fuel, what happens to the food on our plates? This is the heart of the fuel-food debate, a tension between two basic forms of human security, energy and food, that policymakers are still struggling to resolve.

What the fuel-food debate is really about
The fuel-food debate refers to the conflict that arises when crops, agricultural land, and water are used to produce biofuels instead of food. Biofuels are renewable fuels made from biological materials, most commonly bioethanol (blended into petrol) and biodiesel (blended into diesel). The appeal is obvious. They are domestically produced, they reduce dependence on imported oil, and they can lower harmful emissions.
The problem appears when the raw material for these fuels is something people could otherwise eat. Sugarcane, corn, and rice can all be converted into ethanol. When these crops are diverted to fuel tanks, less is available for the food supply, and prices can rise. According to the Food and Agriculture Organization, the diversion of crops to biofuels, along with climate change, ranks among the most significant long-term threats to food security. For a country where a large share of household income still goes towards food, even small price increases matter enormously.
Why India is pushing biofuels so hard
To understand the debate, you first need to understand the motivation. The case for biofuels here is strong and rooted in national strategy.
Cutting the oil import bill
India imports roughly 80% of the crude oil it consumes, which drains foreign exchange reserves and exposes the economy to global price shocks. Biofuels reduce this dependence. The government’s flagship goal has been to blend 20% ethanol into petrol, known as E20. According to NITI Aayog estimates, the E20 programme could cut the crude oil import bill by about $4 billion annually. For an energy-hungry, fast-growing economy, that is a powerful incentive.
Cleaner air and farmer incomes
Blending ethanol also reduces tailpipe pollution. NITI Aayog has noted that petrol blended with 20% ethanol can substantially cut carbon monoxide emissions from vehicles. There is a rural angle too. When farmers face a glut and prices crash, converting surplus grain or sugarcane into ethanol gives them an alternative buyer and helps stabilise prices. The National Policy on Biofuels, 2018 explicitly framed this as additional income for farmers, allowing the use of damaged or surplus food grains for ethanol production.
The food security cost
Here is where the trouble begins. The same crops that fuel the blending programme are food. When demand for ethanol grows, it pulls these resources away from the food system in three connected ways.
Diversion of food crops
Most ethanol blended in India today comes from first-generation (1G) sources, meaning food crops and sugar. The diversion is not hypothetical. In 2022, close to one million metric tonnes of rice fit for human consumption was sold from Food Corporation of India stocks at subsidised rates to make ethanol. Rice and maize that could feed people instead went into fuel. This directly undercuts the country’s nutritional security goals.
Pressure on land and water
Meeting the blending targets requires staggering volumes of feedstock. Analysts estimate that the 2025-26 ethanol target could demand around 275 million tonnes of sugarcane, 6.1 million tonnes of maize, and 5.5 million tonnes of rice, potentially using up to seven million hectares of cropland. Sugarcane is especially demanding because it is extremely water-intensive, and its cultivation is closely linked to groundwater depletion in regions that can least afford it.
The risk of relying on surplus
The government’s defence is that India currently produces a food surplus, so diverting some grain does no harm. But this is a fragile assumption. The current surplus may not last as climate change is projected to stagnate crop yields, and a population that is still growing will need more, not less, food. Critics argue that betting on a permanent surplus is a risky strategy because once food shortages appear, food security will inevitably take priority over fuel.
It is worth noting that the evidence on how much biofuels actually raise food prices is mixed. Some studies have found biofuel production to be a leading driver of rising food prices, while others conclude the effect has been relatively limited. The honest answer is that the impact depends heavily on which feedstock is used and how much land is diverted.
The way out: making fuel without taking food
The most promising response to the debate is simple in principle. If biofuels are made from materials that no one eats, the conflict largely disappears. This is the logic behind advanced, or second-generation (2G), biofuels.
Turning waste into fuel
Instead of food crops, 2G biofuels are produced from lignocellulosic biomass, the tough fibrous parts of plants. This includes agricultural residues, forestry waste, and municipal solid waste. The National Policy on Biofuels, 2018 defines advanced biofuels precisely as those produced from such feedstocks that do not compete with food crops for land use. India generates an enormous quantity of this material. Punjab and Haryana alone produce tens of millions of tonnes of rice straw each year, much of which is simply burned in fields, choking northern India with smoke each winter.
Converting this waste into ethanol solves several problems at once. It produces fuel without diverting food, it reduces stubble burning and the air pollution it causes, and it creates an income stream for farmers from material they previously discarded. The 2018 policy and its 2022 amendment offer financial incentives and viability gap funding specifically to push 2G technology from laboratories into commercial-scale biorefineries. Municipal solid waste is another large untapped resource, with India generating roughly 62 million tonnes of it annually that could be converted into drop-in fuels.
Biodiesel from used cooking oil and animal fats
On the diesel side, biodiesel can be made from used cooking oil and animal fat rather than fresh edible oil. This is significant because India already imports about half its edible oil, so using fresh oil for fuel would be neither affordable nor sensible. The Repurpose Used Cooking Oil (RUCO) initiative, launched in 2019, collects used cooking oil to make biodiesel, which has the added benefit of keeping repeatedly fried, unhealthy oil out of the food chain.
The jatropha experiment
One of the most discussed non-food solutions has been Jatropha curcas, a hardy, non-edible shrub. On paper, it looked like the perfect answer to the fuel-food conflict. Jatropha is drought-resistant, lives for around 50 years, and can grow on marginal and degraded land that is unsuitable for food crops. Because its seeds are poisonous and inedible, growing it does not directly take food away from anyone.
India launched the National Biodiesel Mission in the early 2000s with great enthusiasm, banking on the country’s vast stretches of so-called wasteland. The idea was that villagers could cultivate jatropha on non-farm land, generating rural income while reducing the diesel import bill, without touching a single acre meant for food.
Why the promise faltered
The reality proved more complicated. Jatropha yields on poor soils turned out to be disappointingly low, well below the optimistic projections, making it commercially unviable for many farmers. Worse, the dream of growing it only on barren land did not hold. When yields are low on marginal land, there is pressure to shift it onto better, irrigated land, which brings back the very competition with food crops it was meant to avoid. This is a crucial lesson: a non-food crop does not automatically escape the fuel-food trap if it ends up competing for the same productive land and water.
Balancing two kinds of security
Ultimately, the fuel-food debate is not a question of choosing fuel over food or abandoning biofuels altogether. Energy security and food security are both pillars of human security, and a sustainable path has to protect both. The Asian Development Bank’s analysis of India concluded that first-generation bioethanol generates limited economic benefit relative to its social cost, while a balanced mix of biodiesel expansion, improved energy efficiency, and higher food productivity could deliver better outcomes on all fronts at once.
The emerging consensus points in a clear direction. The future of biofuels lies in shifting away from edible crops and towards waste, residues, and genuinely non-food feedstocks grown on land that does not compete with agriculture. Just as an electric car running on coal-fired electricity is not truly clean, fuel produced at the cost of someone’s meal is not truly sustainable. The goal is fuel that adds to human security rather than trading one form of it for another.
What do you think? Should India press ahead with ambitious ethanol blending targets even while most of its ethanol still comes from food crops, or should the targets wait until waste-based 2G technology can supply them? And given that surplus food production may not last as the climate changes, how much risk to future food security is an acceptable price for energy independence today?
