India's Ethanol Transition: Lessons from Brazil
India is trying to mix more ethanol with petrol, like Brazil did.
In Brazil, people can choose between different ethanol blends or pure petrol, and most cars can run on different mixes.
India is making E20 (20% ethanol) the default fuel, but many people are worried about lower mileage and vehicle compatibility.
Brazil's transition took a long time, with lots of testing and consumer trust.
India is moving faster, but experts say it should take more time to prepare vehicles and consumers for higher ethanol blends.
Brazil offers consumers the choice between different ethanol blends or pure petrol based on price and usage.
India has made E20 the default fuel across all fuel stations, with limited consumer choice.
Brazil built its system around flex-fuel vehicles, allowing drivers to choose their fuel based on price or environmental considerations.
India is moving towards E20 as the default petrol while flex-fuel vehicles remain rare.
Brazil's ethanol transition took decades, with rigorous testing, competitive prices, logistics, and consumer trust.
