Economics of E20

India’s ambitious E20 programme- the blending of 20 percent ethanol with petrol, was presented as an important step towards reducing the country’s dependence on imported crude oil, improving energy security and supporting domestic agriculture. It was also expected to bring wider economic and environmental benefits. However, the transition to E20 has run into several concerns, particularly over vehicle mileage, compatibility with older vehicles, the price of ethanol and, most importantly, why consumers are not seeing cheaper petrol at the pump. The government maintains that E20 has been extensively tested and that there is no evidence of widespread engine damage. However, the concern over fuel economy cannot simply be dismissed. Government and industry assessments acknowledge that some older vehicles designed for E10 can experience a 3 to 5 percent reduction in fuel efficiency. For motorists already paying high fuel prices, even a modest fall in mileage matters. The bigger question is the price benefit. Ethanol has a lower energy content than petrol, and its production cost is not necessarily lower. The government says that maize based ethanol, for example, is currently procured at about Rs.71.86 per litre before taxes, transportation, storage and handling. When crude oil prices are around $70 a barrel, E20 can actually cost more to produce than conventional petrol. Therefore, consumers should not be led to believe that a higher ethanol blend automatically means cheaper petrol. This does not mean the E20 policy should be abandoned. India imports a large share of its crude oil, and reducing that dependence is a legitimate national objective. The ethanol programme has also created a domestic market for agricultural produce and, according to the government, has already helped substitute large quantities of crude oil and save foreign exchange. What needs to change is the way the policy is implemented and explained. On the other hand, electric vehicles are cleaner at the point of use than E20 vehicles because they produce no tailpipe emissions and avoid petrol and ethanol blending altogether. However, their overall environmental benefit depends on how electricity is generated, battery manufacturing and disposal. E20 remains useful for reducing oil imports, but EVs offer greater long-term potential. There is need for more transparency on the actual economics of E20; revelation of long term data on mileage, maintenance costs and vehicle performance rather than relying mainly on official assurances. Then government should inform how ethanol production should not create pressure on food supplies or distort agricultural markets. Finally, the government must ensure that the benefits of the programme are shared by motorists, farmers and the wider economy, rather than allowing the transition to become another policy in which the costs are passed on to consumers. E20 may still be an important part of India’s energy strategy, but its success cannot be measured simply by how much ethanol is blended into petrol. It should be judged by whether it reduces oil imports, lowers the country’s energy vulnerability, benefits farmers, cuts emissions and, above all, provides value to the ordinary consumer. The government has achieved the 20 percent blending target, but the real test now is whether it can make the economics of E20 work for the people who ultimately pay for it.
