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.

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.

MNRE Secy Flags 42 GW RE Capacity Without PPAs, CERC Allows Exit Option for Developers

42 GW of renewable energy capacity is stranded without power purchase agreements (PPAs). High-tariff hybrid and vanilla solar projects are particularly struggling to find buyers among DISCOMs. The CERC has introduced a penalty-free exit option for developers, while MNRE pushes for polysilicon self-sufficiency (30 GW by 2030) and alternative battery technologies like vanadium flow.

Graham Bill Targets India for Russian Oil, US Fed Hikes by 25 bps, Himalayan Monal Alters Calls: UPSC Daily

The Indian Express UPSC Key for September 19, 2026, covers a wide range of high-yield topics: the Graham Bill authorising 100% tariffs on Russian oil buyers (including India), US Federal Reserve rate hike of 25 basis points, a Himalayan monal study showing call frequency change due to human noise, India-China thaw at BRICS, Tata Sons boardroom battle, stubble burning red entry rules, new CBFC guidelines with drug warnings, and India's first mainstream PHEV. Each segment directly aligns with UPSC Prelims/Mains syllabus.

Govt to Launch Lithium-Nickel Scheme; 4 States Identified for Critical Mineral Processing

India is launching a new scheme to process lithium and nickel, critical for EV batteries, with four states identified as hubs. The government has flagged the contradiction of exporting raw minerals while being 100% import-dependent on key minerals, signaling a strategic push toward self-reliance and value addition.

India Crosses 300 GW Non-Fossil Fuel Capacity, Targets 60% by 2035 Under Revised NDC

India has crossed 300 GW of non-fossil fuel electricity capacity (July 31, 2026), achieving 60% of its 500 GW target for 2030. The government has also revised its NDCs for 2035, targeting 60% non-fossil capacity and a 47% reduction in emissions intensity. This milestone is critical for UPSC Environment and Economy syllabus.
