India's energy transition integrates solar growth and ethanol blending

India is navigating a complex energy transition that integrates decarbonization with industrial policy. As the nation aims for net-zero emissions by 2070, falling technology costs are shifting the focus toward the most cost-effective routes for economic development.

Solar energy has seen significant growth, with installed capacity exceeding 150 GW and solar tariffs dropping from approximately ₹17 per unit to below ₹2.50. Competitive bidding and long-term power purchase contracts have successfully attracted private capital to the sector with limited direct government subsidies.

Parallel to the shift toward renewables, ethanol blending serves as a critical tool for reducing oil import exposure. Government data indicates that ethanol blending has saved approximately ₹1.97 lakh crore in foreign exchange and substituted roughly 316 lakh metric tonnes of crude oil. At a 20% blending rate (E20), annual forex savings are estimated at ₹43,000 crore, while providing approximately ₹40,000 crore in annual income to farmers. However, despite these advancements, India’s absolute crude oil imports have continued to rise, with import dependence increasing to over 90% in the 2025–26 period.
