Context
Economic Survey flags that expansion of ethanol blending—especially maize-based ethanol—is affecting food security.
Critical points
• Shift towards maize cultivation driven by ethanol demand
• Reduction in area under pulses and oilseeds
• Increased dependence on edible-oil imports
• Higher domestic food-price volatility
• Greater vulnerability during supply shocks
• Tension between energy self-reliance (ethanol) and food self-reliance
Ethanol blending gains (till Aug 2025)
• Forex savings: ₹1.44 lakh crore
• Crude oil substituted: ~245 lakh tonnes
Basics of ethanol
• Biofuel (alcohol) used for blending with petrol
• Produced via fermentation of biomass (sugar/starch-based)
• Blending reduces crude-oil imports and emissions
