Context:
On January 7, the United States announced its withdrawal from the International Solar Alliance (ISA), raising concerns about global climate cooperation and financing for developing nations.
Key Highlights:
- About ISA
- Established in 2015 (Paris Climate Conference).
- Initiative led by India and France.
- Over 120 member countries.
- Objective: Promote affordable solar energy deployment, especially in developing nations.
- U.S. Contribution
- Contributed approximately $2.1 million over three years (~1% of ISA funds).
- Withdrawal cited lack of alignment with U.S. interests.
- Impact on India
- Limited direct impact on India’s solar industry.
- India’s solar module manufacturing capacity: ~144 GW (2025).
- Solar cell manufacturing capacity: ~25 GW.
- Solar projects driven mainly by domestic demand and long-term contracts.
- Impact on Developing Countries
- Greater risk for African and small developing economies reliant on concessional finance.
- U.S. exit may make global lenders more cautious.
- China Factor
- India imported $1.7 billion worth of PV modules from China (FY25).
- China dominates high-efficiency solar module production.
Relevant Prelims Points:
- International Solar Alliance (ISA):
- Headquarters: Gurugram, India.
- Focus on tropical countries between Tropics of Cancer and Capricorn (initially).
- Photovoltaic (PV) Modules:
- Convert sunlight into electricity using semiconductor materials.
- Global South:
- Developing countries in Africa, Asia, Latin America.
- Solar energy:
- Renewable, non-conventional source.
- Key component of National Solar Mission under NAPCC.
Relevant Mains Points:
GS Paper 2 – International Relations
- ISA as instrument of India’s climate diplomacy and Global South leadership.
- U.S. withdrawal reflects weakening of multilateral climate cooperation.
- Emerging fragmentation in global environmental governance.
GS Paper 3 – Environment & Economy
- Renewable energy transition and climate finance gap.
- Need for stable financing mechanisms for developing countries.
- Strategic risk of overdependence on Chinese solar imports.
Strategic Implications for India
- Opportunity to strengthen leadership in ISA.
- Expand South-South cooperation.
- Boost domestic manufacturing under Atmanirbhar Bharat.
Way Forward:
- Diversify solar supply chains beyond China.
- Expand concessional green finance mechanisms.
- Strengthen ISA’s institutional capacity.
- Promote blended finance models for Africa and small island nations.
