August 28 , 2025 16 hrs 0 min 9 0
  • India plans to increase ethanol blending in petrol to 27 percent by 2030 to boost energy security and reduce oil imports.
  • Ethanol blending has grown from 1.53 percent in 2014 to an expected 20 percent by 2025, saving foreign exchange and cutting emissions.
  • Ethanol reduces carbon monoxide emissions significantly but requires large water use, especially for sugarcane cultivation in water-stressed states.
  • Rising ethanol demand has contributed to maize shortages, affecting food security and causing inflation risks.
  • Vehicles may see reduced fuel efficiency with higher ethanol blends unless designed or modified for them.
  • Second-generation ethanol from crop residues and waste is critical to sustainable growth and reducing food crop dependency.
