How the exam will ask it
Prelims
- E20 petrol is a blend of about 20 per cent ethanol and 80 per cent petrol by volume.
- The Ethanol Blended Petrol programme is administered by the Ministry of Petroleum and Natural Gas, not the Ministry of Agriculture.
- Ethanol blending aims to reduce crude oil imports and support domestic biofuel production from feedstocks such as sugarcane and grain.
Mains
GS Paper 3 (Energy) and GS Paper 2 (Centre-State relations). Issue: a state's lab tests allege ethanol content above the E20 standard, which the Centre disputes. Policy: the Ethanol Blended Petrol programme and fuel-quality standards set by the Centre. Implication: consumer trust, engine and vehicle concerns, and a federal contest over whose testing counts. Way forward: independent, transparent third-party testing, clear dispute-resolution protocols and consumer redress.
