India's First Geothermal Wells Inaugurated at Puga Valley: 1 MW Pilot Project Under National Policy on Geothermal Energy 2025

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.

India's Next Energy Transition: Electrifying Industrial Heat for MSMEs, Manufacturing Competitiveness

India's next energy transition phase targets electrifying industrial heat, especially for MSMEs, to boost manufacturing competitiveness, energy security, and decarbonisation. The article draws a parallel with the solar PV revolution and calls for a coordinated ecosystem of policies, financing, and cluster-level planning to scale the transition.

Doppler Weather Radars: 51st DWR Inaugurated at Sambalpur Under Mission Mausam

India's 51st Doppler Weather Radar was inaugurated in Sambalpur, Odisha, boosting weather forecasting under Mission Mausam. This expansion enhances early warning systems for cyclones, thunderstorms, and heavy rainfall, a core exam topic for disaster management and science-tech.

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.

Cabinet Clears PM-SSY: ₹5,070 Cr for 5,000 MW Floating Solar with Mandatory Storage

The Union Cabinet has approved the Pradhan Mantri Surya Sarovar Yojana (PM-SSY) to build 5,000 MW of floating solar capacity on India's reservoirs with a ₹5,070 crore outlay. Each project must include a 2-hour energy storage system, addressing both land scarcity and grid curtailment issues. This is a high-exam-relevance scheme linking energy transition, climate pledges (500 GW non-fossil by 2030), and decentralized solar deployment.

ISRO Launches EOS-05: India's First Geosynchronous Earth-Imaging Satellite for Strategic & Disaster Monitoring

ISRO has successfully launched EOS-05, India's first earth-imaging satellite placed in geosynchronous orbit. Unlike polar-orbiting satellites, it can continuously observe the same area, making it invaluable for real-time disaster response (floods, cyclones, forest fires), agricultural monitoring, and strategic security applications. This marks a significant leap in India's space-based surveillance capabilities.

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.
