India’s Chief Economic Adviser, V Anantha Nageswaran, has joined the ethanol blending debate. He has called for bringing back E10 petrol for older vehicles. Notably, he wants it sold alongside E20 petrol. Moreover, he has urged caution before India moves beyond E20.
What Is Ethanol Blending?
Ethanol blending means mixing ethanol with petrol. For example, E10 has 10 per cent ethanol, while E20 has 20 per cent. India makes ethanol mainly from sugarcane, damaged grains and maize. Hence, blending cuts oil imports and helps farmers.
Why the CEA Wants E10 Petrol Back
Many older vehicles were not designed for high ethanol blends. Therefore, some owners worry about mileage and engine wear with E20. So, offering E10 petrol for these vehicles gives buyers a choice. In turn, it could ease public concern about the E20 shift.
Food, Fuel and Water Trade-Offs
The CEA also pointed to deeper trade-offs. First, ethanol from grains can compete with food needs. Second, sugarcane and maize need a lot of water. Third, heavy use of these crops can stress groundwater in some regions. Consequently, he advised caution before pushing blending well beyond E20.
India’s Ethanol Journey
India reached the E20 target in 2025, five years ahead of the original 2030 goal. As a result, the country saved foreign exchange and cut carbon emissions. However, the next step needs careful planning. For instance, flex-fuel vehicles and second-generation ethanol from crop waste could help.
The Wider Debate
Supporters say blending boosts energy security and farm incomes. Meanwhile, critics raise concerns about vehicles, water and food prices. Thus, a balanced policy may offer several blends for different vehicles.
Why E10 Petrol Matters for UPSC and UKPSC
Notably, ethanol blending links energy, agriculture and environment. So, remember the E20 timeline and the trade-offs raised by the CEA. Also, prepare points for and against higher blending.
