This strategic milestone is crucial for India's energy security, decarbonisation, and ambition to become a global leader in green hydrogen, navigating significant challenges in cost, infrastructure, and regulatory coordination.
Proposal to Accelerate the Development of Hydro Pumped-storage Projects (PSPs)
In News The Central Electricity Authority (CEA) has proposed a regulatory overhaul to accelerate the development of hydro pumped-storage projects (PSPs). Background Eco-sensitive zones (ESZs) protect fragile ecosystems, and currently PSPs and hydropower projects are banned within ESZs and a 10-km buffer around protected areas. Environmental concerns and local protests in states like Tamil Nadu, Karnataka, Rajasthan, and Maharashtra’s Western Ghats highlight risks to forests and wildlife.
Green Hydrogen to Reshape RE Sector in India
Context In the next five years, technologies like energy storage and green hydrogen would fundamentally reshape India’s renewable energy ecosystem. India’s Green Hydrogen Mission Green hydrogen has emerged as a clean, scalable fuel alternative that can decarbonize hard-to-abate sectors, reduce import dependence on fossil fuels, and support India’s goals for energy security. India targets 5 MMT of Green Hydrogen production annually by 2030.
India Unveils Major Global Solar Initiatives at ISA Assembly
Context India launched a set of flagship global initiatives to accelerate the world’s transition to clean, equitable, and circular solar energy systems at the Eighth session of the International Solar Alliance (ISA). Initiatives Launched The SUNRISE platform: The Solar Upcycling Network for Recycling will connect governments, industries, and innovators to unlock the value embedded in solar waste. By promoting recycling and upcycling, SUNRISE aims to make solar deployment truly sustainable.
India Reframes Its Renewable Revolution
Context India’s renewable energy sector is moving from rapid expansion to building a strong, stable, and resilient system to support its 500 GW non-fossil capacity target by 2030. About In the past decade, India’s installed renewable capacity (excluding large hydro) rose from under ~35 GW in 2014 to over ~197 GW today. India continues to add 15–25 GW of new renewable capacity annually — a rate that remains among the fastest in the world.
Gujarat’s Dhordo Becomes Fully Solar-Powered
Context Prime Minister Modi dedicated Dhordo as a “Solar Village” to the nation during the ‘Samudra Se Samriddhi’ programme in Bhavnagar, Gujarat. About Dhordo will become the fourth solar-powered village in the State, after Modhera in Mehsana, Sukhi in Kheda, and Masali in Banaskantha. It is a remote village in Gujarat’s Kutch internationally acclaimed as the ‘Best Tourism Village’ by the United Nations World Tourism Organisation (UNWTO).
MNRE Unveiled India's First National Policy on Geothermal Energy
Context Recently, the Union Ministry of New and Renewable Energy (MNRE) launched its first national policy on geothermal energy, joining a growing list of countries betting on subterranean heat to achieve net-zero emissions by 2070. Guidelines for States and Union Territories Allocation of geothermal blocks with exploration permits (3–5 years). Single-window clearance system for permits and approvals.
Impact of Ethanol Blending
In News India achieved 20% ethanol blending in petrol (E20) in 2025, five years earlier than the 2030 target set under the National Policy on Biofuels (2018). Way Forward Diversify Feedstock: Shift away from sugarcane to alternative sources such as maize, bamboo, and agricultural residues to reduce environmental impact. Consumer Protection: Implement tax incentives or compensation as recommended by NITI Aayog to address concerns over fuel efficiency drop.
China’s Green Energy Transformation
Context China’s transformation from the world’s largest polluter to a global clean energy superpower is the result of decades of strategic planning, massive state investment, and technological dominance across the renewable energy supply chain. About the Green Energy It has emerged as a cornerstone of sustainable development, as the world confronts the climate crisis. It refers to energy generated from natural, renewable sources that have minimal environmental impact and produce little to no gre
Discovering India's Solar Goldmine
There is a need for data-driven reassessment of India’s solar energy potential to unlock investment, drive innovation, and accelerate the transition to net-zero emissions by 2070.
Share of Clean Energy in India’s Electricity less than 30% despite 50% of installed Capacity
