Ethanol Blending Programme (EBP): Benefits, Challenges, Food Security and Water Concerns

Launch & Objective

• Initiated under the National Policy on Biofuels.

• Aim: Reduce crude oil imports, enhance energy security, promote cleaner fuels.

About EBP

• Ethanol (from sugarcane, maize, rice) blended with petrol.

• India achieved E20 target (20% ethanol blending) ahead of schedule.

Target Composition:

• 20% Ethanol + 80% Petrol

Benefits

• Reduce crude oil imports → Lower dependence on foreign oil.

• Save foreign exchange → Cuts dollar outflow, strengthens reserves.

• Support rupee stability → Reduced external vulnerability.

• Boost farmers’ income → Demand for sugarcane, maize, rice creates new markets.

Challenges

• Overproduction: Capacity >20 bn litres vs. need of 10–11 bn litres → surplus risk.

• Stranded assets: Underutilized ethanol plants due to excess supply.

• Policy push: Soft loans & subsidies led to rapid expansion.

Food Security Concerns

• Shift from pulses/oilseeds → higher imports of edible oils & pulses.

• Import dependence shifts from crude oil → natural gas (fertilizer production).

Environmental Concerns

Water Usage (per litre ethanol):

• Sugarcane → ~2,860 L

• Maize → ~493 L

• Rice → ~10,790 L

Example: Maharashtra

• Sugarcane = 10% cultivated area but consumes ~50% irrigation water.

• Expansion → worsens water stress.

CONCLUSION 

• Focus on water‑use efficiency, crop diversification, food security, resource management.

• Ensure fuel security does not compromise food security or water sustainability.

• Balanced approach: Cleaner fuels with sustainable agriculture.
