India'S green fuel plans are turning hot. Cars in most parts of the country will soon be able to use Bharat III level fuels doped with ethanol. The government is planning to expand distribution of E5 petrol to 21 states, up from the initial 10. Oil companies are thus likely to buy almost two times more ethanol from sugar companies every year. India is the world's fourth largest producer of ethanol, behind the US, Brazil and China, with a total capacity of 2.6 billion litres.
