Air Pollution Cuts India's Solar Power Output by 9.6% (15 TWh) in 2023, Global Average 5.8%: Nature Sustainability Study

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.

India Crosses 300 GW Non-Fossil Capacity, Targets 500 GW by 2030; Solar Leads at 164.59 GW

India has crossed 300 GW non-fossil fuel capacity (300.50 GW as of July 31, 2026), accounting for over 54% of total installed capacity. Solar power leads at 164.59 GW. The country is on track for 500 GW by 2030. Key schemes like PM Surya Ghar have benefited 19 lakh households with zero electricity bills. This milestone is crucial for exams on energy transition, climate policy, and government schemes.

131 GW Canal-Top Solar Potential: MNRE Pilot Scheme, PM Surya Sarovar Yojana Boost Land-Free Renewable Energy

India's vast canal network offers a land-free path to solar power via Canal-Top Photovoltaics (CTPV). With land acquisition for solar projects becoming expensive, CTPV saves land, reduces water evaporation, and improves panel efficiency. A 2024 assessment estimates 131 GW potential, but high costs and structural challenges limit deployment. The PM Surya Sarovar Yojana (floating solar) signals growing policy interest in land-neutral solar.

Amit Shah Flags Off India's First LNG-Powered Train: Dual-Fuel Tech to Cut Diesel Use by 40%

India's first LNG-powered train, flagged off by Amit Shah from Sabarmati, marks a major shift towards cleaner fuel in railways. The dual-fuel system can replace up to 40% of diesel, cutting emissions and saving Rs 23.9 lakh per year per rake. This is a key initiative for sustainable transportation and energy efficiency.

Climate Change Intensifies Clear Air Turbulence: 55% Rise in Severe CAT Over North Atlantic, DGCA Investigates Air India Incident

Climate change is making mid-flight turbulence, especially clear air turbulence (CAT), more frequent and severe. A 2023 study found severe CAT over the North Atlantic rose over 55% in four decades. For exam aspirants, this links climate change impacts to aviation safety, DGCA's regulatory role, and passenger safety protocols.

India’s First LNG-Diesel Dual-Fuel Train Launched by ICF; Compare with Hydrogen Train for UPSC

Indian Railways launched its first LNG-diesel dual-fuel train from Sabarmati on September 27, 2026, following the hydrogen train debut in July. This is a high-yield topic for UPSC Prelims (Science & Tech, Environment) and Mains (GS-3: infrastructure, alternative fuels). The article also explains Kavach (Automatic Train Protection system) – a recurring Prelims favourite.

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.

NPCIL Commences Fuel Loading at RAPP-8: 4th Indigenous 700 MWe PHWR in Fleet Mode

NPCIL has started initial fuel loading (IFL) at Unit 8 of Rajasthan Atomic Power Project (RAPP-8), a 700 MWe indigenous pressurised heavy water reactor (PHWR). This marks a major step in India's fleet-mode nuclear expansion, with commercial operation expected in 2026-27. For exams: understand PHWR technology, AERB's role, and the commissioning sequence (IFL → FAC → power generation).
