E85 Fuel (80–85% Ethanol) Launched for Flex-Fuel Vehicles, Priced at ₹82.12/Litre (~₹20 Cheaper) to Cut Emissions by 61%

India's E20 Fuel Mandate: 240 Million Legacy Vehicles Face Mileage Loss, Contamination Risks

India's nationwide E20 fuel mandate (20% ethanol blending) effective April 1, 2026, aims to reduce crude oil imports but raises serious concerns for 240 million legacy vehicles (pre-2023). Real-world mileage drops of over 10%, fuel system corrosion, phase separation, and contamination risks (chlorides up to 570 ppm, water up to 13,000 ppm) have sparked legal challenges and demands for consumer protection. This is a high-impact issue linking energy policy, automotive engineering, and consumer rights – a must-know for GS3 and GS2.

E20 Ethanol Fuel Used in 4 Crore Vehicles; Flex-Fuel Engines to End ₹22 Lakh Cr Fuel Imports

E20 ethanol-blended petrol is being used in 4 crore four-wheelers and 20 million two-wheelers without harming vehicles and with improved mileage. Union Minister Nitin Gadkari announced that automobile companies will produce flex-fuel engines capable of running on 100% ethanol, potentially saving ₹22 lakh crore in fuel imports and boosting farmers' income through higher maize prices.

BPCL Explores E10 Petrol for Older Vehicles as India Achieves 20% Ethanol Blending Target

India's achievement of 20% ethanol blending has sparked debate over older vehicle compatibility. BPCL is exploring offering E10 petrol alongside E20, backed by CEA's call for consumer choice. This could reshape fuel retail infrastructure and impact millions of two-wheeler owners.

Cabinet Approves Rs 23,731 Cr GOBARdhan Scheme; Rajya Sabha Clears Rs 54,067 Cr Appropriation Bill

GOBARdhan Scheme Approved with ₹23,731 Cr Outlay to Boost CBG Production Tenfold

Union Cabinet approves GOBARdhan, a National Circular Bioenergy Scheme with ₹23,731 crore outlay for 10 years to increase domestic compressed biogas (CBG) production by nearly 10-fold. The scheme aims to reduce natural gas imports, strengthen energy security, and create a commercially viable waste-to-energy ecosystem through assured offtake, administered pricing, capital subsidies, and pipeline infrastructure.

Kudankulam Nuclear Reactor Costs Surge 55%: Impact on India's Nuclear Expansion Plans

Cost of four under-construction nuclear reactors at Kudankulam has risen by 55% to ₹1,38,330 crore, driven by Russia-Ukraine war. This poses a challenge to India's ambitious nuclear expansion plans and could increase electricity tariffs, especially as the government opens the sector to private participation.

Ministry of Mines Notifies 2 Offshore Mineral Blocks Near Great Nicobar for Polymetallic Nodules

India has notified two offshore mineral blocks near Great Nicobar Island for polymetallic nodule and crust exploration, strengthening its critical minerals push under the blue economy framework. This connects directly to the Deep Ocean Mission, Samudra Manthan scheme, UNCLOS, and India's strategic need for deep-sea mineral security. For exams, remember the Act, the minerals, the contracts, and the institutional framework.

MNRE Proposes Polysilicon Incentive; Solar Cell Capacity to Triple to 100 GW

India is planning a support scheme to incentivize domestic polysilicon manufacturing, a key raw material for solar panels currently 100% imported. This move aims to deepen the solar value chain, with solar cell capacity expected to triple to 100 GW within a year. Additionally, renewable energy is helping reduce DISCOM power purchase costs, with RE-RTC tariffs matching nuclear power at Rs 5.25/unit.
