  • [22nd June 2026] The Hindu OpED: End the free rein of junk food advertising in India

    Mentor’s Comment

    India committed in 2017 to restrict the advertising of ultra-processed foods (UPFs) and foods high in fat, sugar and sodium (HFSS) foods under the National Multisectoral Action Plan, but that commitment remains unimplemented. In February 2026, the Supreme Court of India weighed in on the issue through a PIL on front-of-pack warning labels, and the Economic Survey 2025-26 called for stronger regulation of UPF advertising, bringing the policy gap into sharp focus.

    What has made UPF and HFSS advertising a public health concern?

    1. Rising exposure: Children and adolescents encounter UPF advertisements across television, social media, sports broadcasts and influencers.
    2. Misleading health claims: Advertisements highlight selective attributes such as “baked”, “multigrain” or “12-grain” and conceal high sugar, salt and fat content.
    3. Targeted marketing: Celebrity endorsements and child actors increase product appeal among vulnerable consumers.
    4. Demand creation: Advertising does not merely reflect demand. It actively shapes consumer preferences and consumption patterns.
    5. Scale of advertising expenditure: In 2024, three major transnational corporations spent USD 13.2 billion on UPF advertising globally. In India alone, more than two lakh junk food advertisements appeared in a single month, backed by an advertising expenditure of approximately ₹170 crore.

    Why are UPFs increasingly linked to adverse health outcomes?

    1. Industrial formulation: UPFs contain additives, flavour enhancers, emulsifiers and refined ingredients designed for high palatability.
    2. Overconsumption effect: Their design encourages repeated consumption and reduces satiety.
    3. Diet displacement: UPFs replace traditional and minimally processed foods.
    4. Disease burden: Scientific evidence links high UPF consumption to obesity, hypertension, diabetes and cardiovascular diseases.
    5. Rising NCD challenge: Growing UPF consumption coincides with increasing obesity rates globally and in India.

    Why are existing regulatory safeguards proving inadequate?

    1. Policy implementation gap: The National Multisectoral Action Plan (2017-2022) envisaged restrictions on HFSS advertising, but implementation remains incomplete.
    2. Weak disclosure norms: Advertisements can omit critical nutritional information and still remain legally compliant.
    3. Limited consumer protection: Existing rules focus more on product safety than marketing practices.
    4. Judicial concern: The Supreme Court has highlighted the need for stronger consumer information measures such as front-of-pack labelling.
    5. Reliance on self-regulation: Industry-led safeguards have not substantially reduced child-targeted advertising.

    What Is the Constitutional and Legal Basis for Restricting UPF and HFSS Advertising?

    1. State duty to protect vulnerable groups: Children are especially vulnerable to food marketing, requiring state intervention to safeguard public health.
    2. Existing policy commitment: The NMAP (2017-22) envisaged restrictions on HFSS food advertising, but implementation remains pending.
    3. Advertising law as the key instrument: The proposed solution is amendment of advertising laws, a measure already contemplated by the government.
    4. Supporting legal measures: The Supreme Court (2026) endorsed front-of-pack labelling, while MPs have advocated warning labels and taxation of UPFs.
    5. Right to health framework: Regulation of unhealthy food advertising flows from the constitutional right to health and is supported by the Economic Survey 2025-26.

    Does nutrition education alone solve the problem?

    1. Information asymmetry: Consumers receive nutrition advice but are simultaneously exposed to aggressive food marketing.
    2. Behavioural influence: Marketing exploits emotional triggers that often outweigh rational dietary choices.
    3. Children’s vulnerability: Children lack the capacity to critically assess persuasive advertising.
    4. Environmental constraint: Food choices are shaped by the surrounding commercial environment, not only by awareness levels.
    5. Public health limitation: Education programmes cannot fully offset continuous exposure to unhealthy food promotion.

    What do international experiences demonstrate about food advertising regulation?

    1. City of San Francisco lawsuit against UPF manufacturers: In 2024, San Francisco filed a lawsuit against 10 major UPF manufacturers alleging child-targeted marketing, highly compelling product formulations, and inadequate health risk disclosure. The suit sought prevention of deceptive marketing and corrective measures for past false advertising.
    2. Chile: Strong statutory restrictions on unhealthy food advertising reduced reliance on voluntary industry commitments.
    3. Mexico: Regulatory interventions demonstrated greater effectiveness than self-regulation mechanisms.
    4. Global evidence: International experience shows enforceable legal measures outperform voluntary compliance frameworks.
    5. Lancet Series evidence (November 2025): Three papers published in The Lancet in November 2025 presented scientific evidence linking UPF consumption to poorer diet quality, displacement of real foods, hypertension, cardiovascular disease, type 2 diabetes, obesity, and other non-communicable diseases. The series argued that policymaking should not wait for further evidence.

    Why is this ultimately a state responsibility rather than a market choice?

    1. Right to Health: The state has a constitutional duty to protect public health when harms are foreseeable.
    2. Child protection principle: Children constitute a vulnerable group requiring enhanced regulatory safeguards.
    3. Market failure: Consumers often lack complete information about nutritional risks.
    4. Externalities: Rising obesity and NCDs impose social and healthcare costs beyond individual consumers.
    5. Public interest regulation: Restrictions on harmful advertising are comparable to other public health interventions.

    What policy changes are required?

    1. Advertising restrictions: Prohibit or significantly restrict child-targeted advertising of UPFs and HFSS foods.
    2. Front-of-pack labelling: Introduce clear warning labels to improve informed choice.
    3. Digital platform regulation: Extend restrictions to social media, influencers and online advertising.
    4. Stronger enforcement: Replace voluntary compliance with statutory obligations and penalties.
    5. Healthy food promotion: Incentivise marketing of minimally processed and nutritious foods.

    Conclusion

    The central issue is not consumer ignorance but the commercial environment that shapes food choices. Nutrition education cannot succeed when aggressive marketing continuously promotes unhealthy foods. India’s public health response must move beyond awareness campaigns and regulate the advertising ecosystem that drives UPF consumption, especially among children.

  • Guardrails in AI growth to protect developing nations

    Why in the News?

    The United Nations General Assembly established a Global Dialogue on AI and an Independent International Scientific Panel on AI, marking the first attempt to create a global scientific body dedicated to this technology. This development has exposed a core tension: AI governance is simultaneously moving toward global coordination and fragmenting into competing national regulatory frameworks. The asymmetry between AI-capable and AI-dependent nations determines who controls both the risks and the benefits of this transition.

    What is the current global AI governance landscape and why is it structurally insufficient?

    1. Parallel and voluntary structures: Most existing frameworks have voluntary participation, varying legal force, and focus on specific aspects, safety, ethics, or standards, with no common binding floor.
    2. EU AI Act 2024: The most comprehensive binding framework to date. It prioritises safe, transparent, non-discriminatory, and environmentally friendly AI. Its extraterritorial reach is limited to EU-market participants.
    3. UN Global Dialogue on AI: UNGA invited every country to participate. An Independent Scientific Panel makes periodic assessments to inform the Dialogue. It lacks enforcement authority.
    4. Annual global AI summits: The most recent edition was held in New Delhi in February 2025. Outcomes remain consultative and have not produced enforceable international agreements.
    5. Regulatory fragmentation: Each country developing its own framework forces companies to satisfy differing requirements across geographies, creating pressure to favour permissive jurisdictions.
    6. Innovation slowdown risk: Companies may roll out services only in regulatory-friendly markets, deepening access inequality for developing nations.

    What makes global AI governance necessary?

    1. Cross-border technology: AI systems operate across jurisdictions and affect multiple countries simultaneously.
    2. Regulatory fragmentation: Different national regulations increase compliance costs and slow innovation.
    3. Unequal regulatory capacity: Many developing countries lack the expertise and institutions needed to regulate AI effectively.
    4. Global public impact: AI influences economic growth, governance, healthcare, education, and security.
    5. Need for common standards: Shared principles can improve safety, interoperability, and trust.

    How does regulatory fragmentation produce asymmetric harm for developing nations?

    1. Infrastructure concentration: A few countries already possess the computing, talent, and financial resources to support the entire AI ecosystem, before global rules are set.
    2. Regulatory capacity deficit: Many countries in Asia and Africa lack institutions to frame robust domestic AI regulations or protect their national interests in international negotiations.
    3. Data sovereignty trap: Insisting that all AI development remain within national boundaries accelerates power concentration rather than distributing it.
    4. Digital colonisation risk: Developing countries become consumers of AI systems designed elsewhere, with no input into their values, benchmarks, or constraints.
    5. Denial of transformative benefits: AI is a technology of the order of the steam engine. Excluding developing nations from its benefits is a disservice to humanity, not merely to affected countries.
    6. Minimum regulatory floor: A globally agreed set of minimum standards is the only mechanism that ensures developing countries benefit from AI advances without surrendering domestic policy space.

    Does global AI regulation resolve the equity problem or does it risk replicating the nuclear non-proliferation trap?

    The equity problem refers to the structural exclusion of predominantly the Global South from the economic benefits, decision-making processes, and capacity building surrounding artificial intelligence.

    1. Non-proliferation analogy: Global AI regulation could restrict unrestricted AI development to only certain countries or companies, creating a permanent hierarchy between technology producers and users.
    2. Nuclear regime parallel: This outcome embeds existing power differentials into binding international law, replicating a governance structure that legitimises asymmetry rather than correcting it.
    3. Biological and chemical weapons treaties: Existing international agreements already control dangerous dual-use technologies. Proposals may extend this logic to AI models and to the infrastructure required to build them.
    4. Logic of restriction: The case for restricting AI capable of enabling next-generation biological or chemical weapons is logically defensible. The risk is who draws the boundary and in whose interest.
    5. Political capture risk: “Responsible AI” defined by incumbent powers locks in first-mover advantage and treats developing nations as permanent recipients rather than co-producers of governance norms.

    What do international governance models demonstrate about the feasibility of a globally agreed AI floor?

    1. EU AI Act: binding regulatory precedent: Demonstrates that comprehensive, legally enforceable AI governance is achievable at supranational scale. Sets de facto global standards through market leverage.
    2. UN Global Dialogue: universalist participation model: Universal country invitation distinguishes it from club-based governance. Participatory architecture is its most relevant design feature for developing nations.
    3. Google AI Commons: private open-access precedent: Demonstrates that large AI actors can adopt open-access norms voluntarily. Lacks enforceable accountability.
    4. Trusted AI Commons: India-hosted hybrid model: A one-stop repository of tools, benchmarks, datasets, and protocols for testing AI deployment, with liberal licensing. Significant as a Global South-led governance mechanism.
    5. Limits of existing models: None produces a binding universal minimum floor. The EU Act covers only its market; the UN Dialogue lacks enforcement; Commons models are voluntary. The gap between architecture and enforceable standards remains open.

    What is the Trusted AI Commons and does it constitute an adequate institutional response to the governance deficit?

    1. Definition: A repository of tools, benchmarks, datasets, and protocols needed to develop and deploy AI systems safely and responsibly. Functions as a one-stop shop for AI testing and deployment support.
    2. Institutional origin: Main outcome of the New Delhi AI Impact Summit, February 2026. Hosted and managed by India through India’s AI Mission.
    3. Licensing design: Open, accessible, with liberal licensing. Aggregates tools already developed worldwide, including by IIT Madras, rather than commissioning new ones.
    4. Practical function (example): A country testing an AI system for agriculture can use the Commons to locate available tools, benchmarks, datasets, and protocols in one place, without needing domestic AI infrastructure to find or validate them.
    5. Adequacy gap: Addresses the access and deployment deficit. Does not create a binding minimum floor. Does not build regulatory capacity in developing nations. Necessary but insufficient.
    6. India’s strategic significance: Hosting the Commons positions India as a norm-setter rather than a norm-follower, consistent with its broader foreign policy of strategic autonomy: the ability to act independently of major power blocs in international affairs. 

    The Trusted AI Commons

    1. It is an open, federated, and voluntary global platform designed to serve as a consolidated repository for AI safety benchmarks, evaluation tools, standards, and deployment frameworks.
    2. The initiative was integrated into the New Delhi Declaration on AI Impact.

    Core Objectives & Utility: The platform is designed to act as a “one-stop shop” for developers, researchers, and regulators to access non-proprietary resources.

    1. Open Accessibility: Provides tools under liberal, open-source licensing to prevent safety mechanisms from being locked behind big-tech barriers.
    2. Standardised Evaluation: Hosts cross-jurisdictional benchmarks to test AI behavior against bias, misalignment, and operational errors before deployment.
    3. Global Interoperability: Fosters cross-border collaboration by mapping technical safety frameworks across different international standards.

    Hosting and Management

    1. Initial Leadership: The Trusted AI Commons is initially hosted and managed by India under the auspices of the Ministry of Electronics and Information Technology (MeitY) and the IndiaAI Mission.
    2. Collaborative Network: Rather than building every mechanism from scratch, it aggregates tools from leading global research bodies, such as the Centre for Responsible AI (IIT Madras), the UK AI Security Institute, and Mozilla

    Conclusion

    Fragmented national AI regulation concentrates power in AI-capable nations and denies developing countries both protection and access. A globally agreed minimum regulatory floor is the necessary condition for equity but if framed through non-proliferation logic, it encodes existing power hierarchies into international law. The Trusted AI Commons addresses the access deficit but does not substitute for binding global governance. The central unresolved precondition is universal participation in the design of global AI rules, not merely in their implementation.

  • Biochar offers a way to turn India’s farm smoke into black gold

    Why in the News?

    Punjab and Haryana burn over 20 million tonnes of paddy straw annually because no commercially viable alternative exists for farmers with short post-harvest windows. This mass burning releases greenhouse gases and fine particulate matter while destroying soil organic carbon that depleted soils urgently need. At this time, biochar can come as a solution to India’s twin challenges of stubble burning and declining soil health.

    Why does India’s biomass abundance produce soil poverty rather than soil wealth?

    1. Paradox of abundance: India generates large volumes of crop residue after each harvest. This biomass contains organic carbon that could restore depleted soils. Instead, it is burned in the field.
    2. Structural driver of burning: Short post-harvest intervals between kharif and rabi crops leave farmers with insufficient time to incorporate residue into soil. The absence of affordable alternatives makes open burning the default.
    3. Dual consequence of burning: Burning releases greenhouse gases and fine particulate matter. It also eliminates organic matter that would otherwise improve soil structure, water retention, and microbial activity.
    4. Soil organic carbon crisis: Agricultural soils across India suffer from low soil organic carbon, poor water-holding capacity, and rapid nutrient loss. Low organic carbon reduces crop productivity independently of fertiliser inputs.
    5. Climate vulnerability: Degraded soils with low water-holding capacity make crops more vulnerable to moisture stress. Soil health is therefore a climate adaptation variable, not only a productivity variable.

    What is biochar and what does it do to soil that conventional crop management does not?

    1. Definition: Biochar is the carbon-rich solid produced when organic material is heated at high temperature in a low-oxygen environment through pyrolysis: the thermal decomposition of material in the absence of oxygen.
    2. Persistence: Biochar resists biological decomposition and remains locked in soil for centuries. Conventional compost decomposes quickly, releasing carbon back into the atmosphere.
    3. Porous structure: Biochar is highly porous. This aggregates soil particles, increases water-holding capacity by 10% to 25%, and creates microhabitats for beneficial soil microorganisms.
    4. Productivity gains: Studies indicate biochar addition to degraded soils improves crop productivity by 10% to 30%, particularly in nutrient-poor soils.
    5. Field evidence from India: Biochar from maize stalks applied to black soils in Akola, Maharashtra improved soil organic carbon and overall soil fertility in field trials. Kerala research on coconut leaf stalk biochar showed improved soil quality across cropping systems.
    6. Integration pathway: Biochar can be incorporated into natural farming, soil health management, and carbon farming programmes without requiring farmers to change cropping systems.

    What problem does biochar seek to solve?

    1. Crop residue burning: Punjab and Haryana burn over 20 million tonnes of paddy straw annually due to short harvesting windows and limited alternatives.
    2. Air pollution: Residue burning releases greenhouse gases and fine particulate matter.
    3. Loss of soil nutrients: Burning destroys organic matter that could have been returned to agricultural soils.
    4. Declining soil quality: Many Indian soils suffer from low soil organic carbon, poor water retention, and nutrient depletion.
    5. Resource inefficiency: Agricultural biomass is treated as waste instead of being recycled into productive use.

    Why is biochar relevant for India’s climate and sustainability goals?

    1. Climate adaptation: Healthy soils improve resilience against droughts, heatwaves, and erratic rainfall.
    2. Reduced input dependence: Better nutrient retention lowers reliance on external inputs.
    3. Support for natural farming: Biochar complements natural farming and soil health initiatives.
    4. Carbon sequestration: It removes carbon from the atmosphere and stores it in soils.
    5. Circular economy: Agricultural waste is converted into a productive resource.

    How do carbon credits convert biochar from an agronomic input into an economic model for farmers and cooperatives?

    1. Carbon credit mechanism: Biochar sequesters carbon dioxide in stable form. Verified sequestration earns carbon credits tradeable on voluntary and compliance carbon markets.
    2. Rigorous eligibility of biochar carbon: Biochar carbon satisfies rigorous stability criteria for long-term sequestration. It is classifiable as persistent carbon dioxide removal under accepted accounting standards.
    3. Quantified yield per tonne: The VM0042 methodology from Verra quantifies both avoided emissions from residue burning and long-term soil carbon sequestration. Each tonne of certified biochar generates 2.2 to 2.8 tonnes of carbon dioxide-equivalent credits.
    4. Revenue pathway: Certified biochar can be sold on carbon markets at prevailing prices. This provides additional income for project developers, farmers, and cooperatives with no current economic return on residue management.
    5. Policy packaging: The government can package biochar production and carbon registry registration into a single programme. This creates a strong economic incentive for mass adoption among farmers who currently default to burning.
    6. KISAN kiln test case: The KISAN kiln developed at IIT-Kharagpur is being tested in projects that allow smallholder farmers to monetise farm waste through certified biochar production. This confirms the income model is operationally feasible at the farm level.

    What do international examples reveal about the conditions required for biochar to scale beyond pilot projects?

    1. Kenya: rice husk conversion: Kenya has turned rice husks into certified biochar that improves soil pH and phosphorus content. This shows locally available residue can generate internationally certifiable credits without high-cost imported technology.
    2. Thailand: national policy integration: Thailand has pushed biochar adoption through national initiatives linking soil rehabilitation to carbon management. This shows mass adoption requires government-coordinated demand creation, not supply-side technology promotion alone.
    3. Brazil: Embrapa sugarcane biochar: Brazil’s Embrapa Institute has reported high carbon retention and large yield gains from on-farm biochar generated from sugarcane bagasse. National carbon registry access created a direct policy-to-market pipeline sustaining farmer incentives.
    4. Common design feature: All three cases combine decentralised pyrolysis with strong MRV: measurement, reporting, and verification, the process of quantifying emissions reductions to qualify for carbon credits. No country achieved scale without certified MRV.
    5. Implication for India: India possesses similar feedstock diversity and agricultural scale. The gap is the absence of a certified MRV framework linking farm-level production to a national carbon registry accessible to smallholders.

    Why does biochar’s proven effectiveness at the plot level not automatically translate into national adoption?

    1. Pilot trap: Biochar in India remains confined to research trials and pilot projects and is alien to most farmers. A technically proven intervention can remain permanently at pilot scale when the economic incentive structure and delivery ecosystem are absent.
    2. Residue as disposal problem, not resource: Agricultural residues are seen only as a disposal problem in India. This framing prevents investment in the infrastructure needed to treat residue as a revenue-generating raw material.
    3. Carbon market access gap: Accessing carbon markets requires certified MRV, registry registration, and linkage to buyers. Smallholder farmers lack the institutional capacity to navigate this individually. Cooperative aggregators are necessary intermediaries that do not yet exist at scale.
    4. Market linkage absent: Carbon credit revenue requires market linkages, entrepreneurship, and cost-effective technology access. These supply-chain components are absent in most states. The value of biomass can only be realised through an integrated ecosystem linking innovation, investment, and markets simultaneously.
    5. Not a knowledge problem: Pyrolysis technology, carbon accounting methodology, and agronomic evidence all exist. The constraint is consistent failure to assemble the institutional and market infrastructure needed to execute at scale.

    How does expanding biochar feedstock to urban organic waste extend both the circular economy potential and the climate benefit?

    1. Urban feedstock volume: India generates around 62 million tonnes of municipal solid garbage per year. More than 50% is biodegradable. Sewage sludge and crop residues can also be converted into biochar.
    2. Circular economy rationale: Converting urban organic waste into biochar is consistent with circular economy: an economic model that keeps materials in use, regenerates natural systems, and designs out pollution. Waste diverted from landfills stops producing methane and becomes a useful product instead.
    3. Waste-stream conversion: Biochar production from urban organic waste turns large waste streams into a product with economic value. This reduces municipal waste management costs while providing soil amendment supply for agriculture.
    4. Climate mitigation contribution: Urban biochar production combines landfill methane avoidance with long-term soil carbon sequestration. Both effects are separately quantifiable and certifiable, adding to India’s climate mitigation commitments.

    Conclusion

    India’s parallel crises of air pollution and soil degradation share a single root: the treatment of biomass as waste rather than as a resource. Biochar resolves this at the technical level. The unresolved problem is institutional: no integrated ecosystem linking decentralised pyrolysis, certified carbon markets, national registry access, and farmer income pathways currently exists at scale. Even if pyrolysis technology proliferates and carbon credit prices appreciate, these gains cannot reach smallholder farmers without cooperative aggregation structures, state-backed MRV frameworks, and policy packaging that makes the full farm-to-market pipeline accessible. The next step is not more pilots. It is building the infrastructure that converts proven plots into national scale.

  • [20th June 2026] The Hindu OpED: India’s cheapest power is here, the grid must catch up

    PYQ Relevance[UPSC 2013] Write a note on India’s green energy corridor to alleviate the problem of conventional energy.
    Linkage: The question examines the role of transmission infrastructure in enabling large-scale renewable energy integration.The article shows that transmission bottlenecks, not generation capacity, have become the main constraint on India’s clean-energy transition, reinforcing the importance of the Green Energy Corridor.

    Mentor’s Comment

    India now produces some of the world’s cheapest solar and wind power, yet more than 50 GW of completed renewable capacity remains stranded not because projects are unfinished, but because grid connectivity and transmission is unavailable.

    Why Has Transmission Become the Binding Constraint in India’s Energy Transition?

    1. Cheapest Source of Power: Solar and wind have emerged as India’s lowest-cost electricity sources, with firm clean power available at around ₹3.5 per kWh when paired with storage.
    2. Rapid Renewable Expansion: India added over 45 GW of renewable capacity in 2025 and currently has about 250 GW installed, with another 100 GW under construction.
    3. Existing Base and Pipeline: India currently has about 250 GW of renewable capacity installed and another 100 GW under construction, indicating that transmission expansion is lagging generation growth.
    4. Stranded Renewable Capacity: More than 50 GW of completed renewable projects remain unable to evacuate power due to transmission shortages.
    5. Mismatch in Project Timelines: Renewable projects can be commissioned within 12-18 months, whereas transmission corridors often require 3-5 years.
    6. Future Scale Requirement: India may require nearly 2,000 GW of renewable capacity by 2050 to meet rising electricity demand and electrification goals.

    How Can Existing Grid Assets Unlock Nearly 1,000 GW of Additional Clean Energy?

    1. Storage at Renewable Sites: Batteries can store surplus daytime generation and supply power during evening peaks, significantly increasing utilisation of existing transmission lines.
    2. Reuse of Coal Corridors: Underutilised transmission infrastructure connected to coal plants can be shared with renewable projects, unlocking the equivalent of nearly 100 GW of clean-energy capacity.
    3. Leveraging Existing Substations: Available capacity at transmission substations can accommodate additional renewable connections and support battery integration, enabling another 100 GW equivalent.
    4. Reconductoring Existing Lines: Replacing older conductors with high-temperature, low-sag conductors can nearly double power-carrying capacity on the same towers.
    5. Combined Impact: Storage, shared infrastructure, and reconductoring together can unlock more than 1,000 GW of clean-energy potential within the existing transmission footprint.

    Does Better Grid Utilisation Solve the Problem or Merely Defer It?

    1. Fastest Short-Term Solution: Grid optimisation can be deployed within months and quickly connect stranded renewable projects.
    2. Not a Substitute for Expansion: Existing infrastructure alone cannot support India’s projected renewable requirement of 2,000 GW.
    3. Scale Limitation: Future renewable parks and industrial electrification will require entirely new transmission corridors.
    4. Sequencing Advantage: Optimisation provides immediate relief while larger transmission projects are planned and executed.
    5. Grid Expansion Imperative: India plans a 40% expansion of its transmission network over the next decade, costing more than $100 billion. New corridors must incorporate advanced conductors and storage compatibility to avoid recreating future bottlenecks.
    6. Core Tension: The cheapest and fastest solution is grid optimisation, but the durable solution remains large-scale transmission expansion. Both approaches are necessary.

    What Regulatory and Policy Changes Are Needed?

    1. Storage-Linked Renewable Planning: Regulators should promote greater integration of storage with renewable projects to improve grid utilisation.
    2. State-Level Implementation: States and distribution utilities must incorporate storage and grid-efficiency measures into procurement and planning decisions.
    3. Technology-Oriented Procurement: Procurement norms should reward advanced transmission technologies that expand capacity without requiring new corridors.
    4. Integrated Infrastructure Planning: Renewable energy zones and transmission corridors should be developed in a coordinated manner.
    5. Future-Proof Transmission Design: New transmission infrastructure should be designed for significantly higher renewable penetration from the outset.

    What Does International Experience Reveal About Transmission Bottlenecks?

    1. United States: Delays in connecting renewable projects to the grid have emerged as a major obstacle to the clean-energy transition.
    2. Europe: Several European countries face similar transmission constraints despite substantial renewable deployment.
    3. Common Lesson: Cheap renewable generation alone does not guarantee energy transition success unless transmission capacity keeps pace.
    4. India’s Advantage: A unified national grid and a strong record of transmission expansion provide India with an opportunity to avoid similar bottlenecks.

    Conclusion

    India’s energy transition has moved from a generation challenge to a transmission challenge. The fastest gains lie in optimising existing grid infrastructure through storage, shared transmission assets, and reconductoring, which together can unlock nearly 1,000 GW of additional clean-energy potential. However, optimisation only buys time; achieving India’s long-term renewable ambitions requires simultaneous investment in new, high-capacity transmission corridors. India’s success will depend on pursuing both tracks together.

  • The key hurdle to climate targets: Electrification

    Why in the News?

    At the Bonn climate talks, Turkey proposed raising the global electrification target to 35% by 2035, ahead of hosting COP31 in Antalya with Australia in November. Electricity meets only a small fraction of the world’s energy needs, and most of that electricity is itself generated from fossil fuels. This exposes a gap between rising clean electricity generation and the much slower pace at which economies actually switch their energy consumption to electricity.

    Where does electrification fit among existing global climate goals?

    1. Paris Agreement temperature targets: The 2015 Paris Agreement commits the world to limiting the rise in global temperatures within 2 degrees Celsius, preferably 1.5 degrees Celsius, from pre-industrial times.
    2. Renewable capacity target: Annual COP meetings have produced the goal of increasing the installed capacity of renewable energy.
    3. Net-zero target: COP meetings have also produced the goal of achieving a global net-zero emissions target.
    4. Climate finance target: Mobilising climate finance is a further goal that has emerged from COP meetings.
    5. Electrification as a new addition: The 35% electrification target, if agreed upon, would be one more addition to this existing set of climate-related global goals, all aimed at reducing the world’s dependence on fossil fuels and speeding up the energy transition.

    How is the progress of the energy transition measured?

    1. Total Primary Energy Supply (TPES): A measure of all energy available for use in an economy, including energy consumed in producing, transforming and transporting energy itself.
    2. Final Energy Consumption (FEC): A measure of energy ultimately used by end-consumers. It excludes energy burnt to produce electricity, energy used in refining petroleum, diesel burnt in transporting fuel, and transmission and distribution losses.
    3. Structural difference between fossil fuels and renewables: Fossil fuels are direct sources of energy and only require to be burnt to produce energy, whereas renewable sources such as solar, wind, nuclear or hydropower have to be converted into electricity before they can be put to use.
    4. Why electrification rate is the relevant metric: Because renewable sources require conversion into electricity before use, every final use of energy would have to be electrified for a complete transition away from fossil fuels to be possible.

    Why does electrification remain limited despite rising electricity demand?

    1. Slow movement in FEC share: Electricity’s share in FEC rose only from 17.7% in 2015 to 21% in 2025, a modest increase over a decade.
      1. Global electricity share in FEC: Electricity accounted for only 21% of total final energy consumption (TFEC) in 2025, according to the IEA.
      2. India’s electricity share in FEC: The corresponding figure for India is about 23%, according to government data.
    2. Rising generation volumes: Global electricity generation increased from about 24 terawatt-hours (TWh) in 2015 to over 32 TWh in 2025, a rise of nearly 33%.
    3. Generation growth has outpaced consumption-side electrification: Electricity output rose by a third over the decade while its share of final consumption rose by only about 3 percentage points.
    4. Hard-to-electrify sectors persist: Shipping, aviation, heavy-duty and long-haul trucks, high-temperature industrial processes in iron, steel, cement and ceramics, and many residential needs like heating remain largely unelectrified and cannot run on renewables.

    Which sectors remain difficult to electrify?

    1. Aviation: Long-distance air travel lacks commercially viable large-scale electric alternatives.
    2. Shipping: Heavy maritime transport depends on high-energy-density fuels.
    3. Heavy Industry: Steel, cement and chemicals require high-temperature industrial processes.
    4. Long-Haul Freight: Heavy trucks face battery and charging limitations.
    5. Energy-Intensive Manufacturing: Several production processes remain dependent on fossil fuels.

    Why does renewable energy success not automatically translate into climate success?

    1. Steady rise in clean generation share: The share of non-fossil sources (renewables, hydro and nuclear) in electricity generation rose from 33.6% in 2015 to 42.6% in 2025, according to the IEA.
    2. Electricity itself is still the majority fossil: In 2025, only about 42% of all electricity generated worldwide came from non-fossil sources, meaning most electricity generated is still fossil-based.
    3. Compounding effect on total energy use: Only 21% of total final energy consumption is met through electricity, and only about 42% of that electricity is clean.
    4. The reality-check figure: This means just over 8% of total energy consumed in the world is currently clean.
    5. Three decades of policy effort, limited consumption-side result: Nearly three decades of favourable policies, financial incentives and technology innovation to promote cleaner fuels have left more than 90% of current global energy use still dependent on fossil fuels.

    How ambitious is the proposed 35% electrification target?

    1. IRENA’s threshold for 1.5°C: The International Renewable Energy Agency states that a 35% electrification rate by 2035 is the minimum needed to keep any realistic hope of staying on the 1.5-degrees Celsius pathway.
    2. Investment requirement: Achieving that level of electrification requires about $1.2 trillion to be pumped into electricity systems every year.
    3. Accompanying requirements: Rapid expansion in renewables and battery storage systems must also happen alongside this investment.
    4. Scale of the gap from current trajectory: The IEA projects electricity’s share of global FEC will rise to only about 24% by 2030, against a target of 35% by 2035, even as non-fossil sources (renewables plus hydro and nuclear) are projected to supply nearly half of global electricity by 2030.

    What risks could derail even this limited trajectory?

    1. Geopolitical uncertainty: It is unclear how wars and geopolitical tensions will affect the pace of energy transition.
    2. Two opposing pressures: Greater uncertainty in fossil fuel supplies and rising oil prices may push some countries toward renewables, while the economic fallout of conflicts may squeeze budgets available for new technologies and infrastructure.
    3. Risk of reverting to convenient fuels: Countries may be tempted to use whatever energy source is easily available, regardless of its climate impact.

    What do international targets indicate about the future direction of climate policy?

    1. COP28 Consensus: Countries agreed to accelerate the global energy transition.
    2. IRENA Roadmap: The agency proposes raising electrification to 35% by 2035.
    3. Net-Zero Pathways: Most credible decarbonisation scenarios require major electrification gains.
    4. Renewables-Electrification Link: Renewable expansion and electrification must progress together.
    5. Long-Term Transition: Climate targets increasingly depend on transforming energy consumption patterns, not merely energy production.

    Conclusion

    Clean electricity generation has scaled steadily, but the constraint on climate targets has shifted to how much of total energy consumption is electrified, not how clean the electricity supply is. Only about 8% of global energy consumption is currently clean, and electricity’s FEC share is projected to reach just 24% by 2030 against a 35% by 2035 target. Hence, climate progress will remain limited unless transport, industry and buildings convert their direct fossil-fuel use to electricity at a much faster pace.
