  • [28th January 2026] The Hindu OpED: Manufacturing woes: Capital support alone will not add to battery cell manufacturing capacity

    PYQ Relevance

    [UPSC 2017] Account for the failure of the manufacturing sector in achieving the goal of labor-intensive exports. Suggest measures for more labor-intensive rather than capital-intensive exports. 

    Linkage: This PYQ directly aligns with GS III (Industrial Policy, Manufacturing, Employment) by examining why India’s manufacturing remains capital-intensive despite policy support like PLI. 

    Mentor’s Comment

    This article is critical for GS Paper III (Energy, Infrastructure, Industrial Policy). It highlights structural limits of India’s PLI-driven manufacturing strategy, especially for technology-intensive green sectors, and questions the assumption that fiscal incentives alone can deliver strategic self-reliance.

    What Is the Strategic Objective Behind Non-Fossil PLI Schemes?

    1. Energy Transition Target: Supports installation of 500 GW non-fossil capacity by 2030.
    2. Industrial Deepening: Enables domestic manufacturing of solar and battery components.
    3. Import Substitution: Reduces reliance on imported green technologies.
    4. Global Integration: Positions India as a supplier in global clean-energy value chains.

    How Have PLI Schemes Performed Across the Value Chain?

    1. Downstream Assembly: Achieved 56% of target in solar module assembly by mid-2025.
    2. Upstream Manufacturing: Remains a bottleneck in both solar and batteries.
    3. Value Chain Imbalance: Assembly expanded faster than material and component production.

    Why Are Upstream Solar Manufacturing Segments Lagging?

    1. Polysilicon Manufacturing: Achieved only 14% of the target capacity.
    2. Wafer Manufacturing: Reached merely 10% of the planned capacity.
    3. Capital Intensity: Requires high upfront investment with long gestation.
    4. Technology Dependence: Relies on specialised global expertise and equipment.

    What Explains the Failure in Battery Cell Manufacturing?

    1. Target Capacity: 50 GWh of domestic battery cell production.
    2. Fiscal Outlay: ₹18,000 crore under PLI.
    3. Actual Commissioning: Only 1.4 GWh (2.8%) by late 2025.
    4. Domestic Value Addition Rules: Mandate 25% within two years and 60% within five years.
    5. Gigafactory Complexity: Requires advanced infrastructure and long-term R&D ecosystems.

    How Do Policy Design Constraints Affect Outcomes?

    1. Capital-Only Incentives: Assume finance can substitute for expertise.
    2. Skill Deficits: Ignore the need for decades of workforce training.
    3. Technology Transfer Limits: International transfers are capital-intensive and slow.
    4. Penalty Structure: Firms face steep fines for missing deadlines despite structural hurdles.

    What Role Do External Dependencies Play?

    1. Imported Raw Materials: Persistent reliance on foreign inputs.
    2. Specialised Expertise: Dependence on foreign technical experts.
    3. Visa Restrictions: Non-issuance of visas to Chinese technicians delayed factory setup.
    4. Supply Chain Risk: Increases vulnerability in strategic energy sectors.

    Why Has the Telecom PLI Succeeded While Green PLIs Struggle?

    1. Lower Technology Entry Barriers: Telecom manufacturing required fewer foundational innovations.
    2. Established Ecosystems: Global supply chains were already mature.
    3. Faster Market Realisation: Sales-linked incentives translated quickly into output.
    4. Green Tech Contrast: Solar and batteries require upstream industrial ecosystems, not just assembly.

    What Rethinking Does the Article Suggest for PLI Design?

    1. Expertise-Based Selection: Prioritises technical capability over net worth.
    2. Capital Risk-Sharing: Considers additional capital subsidies for upstream segments.
    3. Longer Timelines: Aligns targets with technology development cycles.
    4. Ecosystem Approach: Integrates R&D, skills, and industrial infrastructure.

    Conclusion

    Capital support alone cannot manufacture technological capability. India’s clean-energy ambitions require patient industrial policy, focused on skills, research, and ecosystem creation. Without recalibrating PLI design to reflect the realities of high-technology manufacturing, the gap between targets and outcomes is likely to persist.

  • Water Bankruptcy and Global Agriculture

    Why in the News?

    A recent UN report titled Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post Crisis Era, released by United Nations University Institute for Water, Environment and Health on 20 January 2026, warns that the world has entered a phase of global water bankruptcy, severely impacting agriculture and food security.

    What is Water Bankruptcy?

    • A condition where long term water use exceeds renewable inflows and safe depletion limits
    • Agriculture is no longer facing a temporary water crisis but operating beyond hydrological sustainability
    • Rivers, lakes, aquifers, wetlands, soils and glaciers damaged beyond realistic recovery

    Key Findings of the Report

    • Agriculture and Water Use: ~70 percent of global freshwater withdrawals used for agriculture.Expansion of agricultural land is no longer viable
    • Scale of Exposure:~3 billion people live in areas with declining or unstable water storage. More than half of global food production located in water stressed regions. 170 million hectares of irrigated cropland under high or very high water stress.
    • Land and Soil Degradation: Over 50 percent of global agricultural land moderately or severely degraded. Global salinisation has degraded. 82 million hectares of rainfed cropland. 24 million hectares of irrigated cropland. Accelerates desertification and reduces soil moisture retention.
    [2021] Among the following, which one is the least water efficient crop?
