• Background on Solar Energy in India:

  • By 2024-25, India generated 1,08,494 GWh of solar energy, surpassing Japan (96,459 GWh), becoming the third-largest solar producer globally after China and the USA.
  • India’s solar module manufacturing capacity increased from 2 GW in 2014 to 100 GW in 2025 (Ministry of Renewable Energy).
  • Current domestically installed solar capacity is approximately 117 GW as of September 2025; the effective production capacity is around 85 GW.

• Climate Commitments:

  • As part of its climate commitments, India aims to source 50% of its power from non-fossil fuel sources by 2030, which translates to 500 GW total.
  • Of this, 250-280 GW is expected from solar, requiring an addition of about 30 GW annually, although recent actual additions have been only 17-23 GW per year.

• Economic Factors:

  • Domestically manufactured solar modules are 1.5 to 2 times more expensive than those imported from China due to the latter's superior production capacity and economies of scale.
  • India managed an export of around 4 GW of solar modules to the USA in 2024, significantly lower compared to China’s 236 GW annual export.

• Government Schemes:

  • PM Kusum: Aims to provide solar power to rural India, enhancing energy access.
  • PM Surya Ghar: Focuses on promoting rooftop solar installations in urban areas. Both schemes are essential for domestic adoption, although they need further advancements.

• International Initiatives:

  • India is positioning itself as a potential solar supplier to Africa through the International Solar Alliance. The continent, currently limited to effectively utilizing only 4% of its arable land for irrigation, presents an opportunity for solar-powered irrigation solutions.

• Challenges and Strategies:

  • Although India has substantial manufacturing plans, the domestic and export strategy requires development of new markets to ensure sustainability amidst competition from China.
  • India’s overtures towards Africa are a strategic move to enhance its solar industry viability and access new markets.

This summary encapsulates India’s solar power industry advancements, commitments, challenges in manufacturing, government initiatives, and international strategies, aligned with academic-focused examination requirements.

Green Crackers: An Overview

Definition and Development:

• Green Crackers: Developed by CSIR–NEERI to combat hazardous pollution caused by traditional firecrackers.
• Key Brands: SWAS (Safe Water Releaser), STAR (Safe Thermite Cracker), SAFAL (Safe Minimal Aluminium).
• Objective: Reduced smoke, noise, and harmful emissions associated with traditional fireworks.

Chemical Composition:

• Traditional firecrackers consist of potassium nitrate, barium nitrate, aluminum powder, sulfur, and charcoal, causing significant emissions (PM₂.₅, PM₁₀, SO₂, NOₓ).
• Green crackers reformulate chemical mixtures:
  • Reduction of Toxic Metals: Barium nitrate replaced with potassium nitrate or strontium salts.
  • Additives: Incorporates zeolite and iron oxide to suppress dust and capture soot.

Emission Reductions:

• Emission tests show that green crackers cut PM and gas emissions by 30-40% compared to traditional types (Source: Wankhede et al., Environmental Pollution 2023).
• Reduction in airborne PM₂.₅ and PM₁₀ by 30-60% due to lower barium content.

Environmental and Health Concerns:

• Presence of residual toxins: Emissions still contain trace amounts of aluminum, copper, and strontium.
• Soil contamination observed after firecracker burning; elevated levels of micronutrients in ash and soil (Source: Dubey & Rai, Journal of Laser Applications 2024).
• Health risks associated with metal-rich particulate matter; linked to respiratory, cardiovascular, and neurological issues (Source: Mehra et al., Pollution Research 2022).

Impact on Air Quality:

• Despite lower emissions, ultrafine particles (UFPs) have increased; detected UFP concentration rose by 138% post green cracker use in Delhi (Yadav et al., Journal of Environmental Management 2022).

Implementation Challenges:

• Green crackers carry a logo and QR code for authenticity verification.
• Counterfeit products have compromised the system's effectiveness in distinguishing genuine low-emission crackers.

Global Context:

• Other countries are exploring low-emission formulations without formal certification processes for "green" products.
• Countries, including China and EU member states, have imposed restrictions on fireworks to mitigate air quality issues.
• India is the only nation with a certified program for developing low-emission fireworks.

Conclusion:

• Green crackers represent an improvement in emissions but should not be considered a complete solution to pollution.
• Experts suggest a gradual transition towards cleaner alternatives, emphasizing the need for societal transformation towards sustainable practices.
• Acknowledged importance of broader changes in energy consumption, waste management, and transportation to combat climate change and air quality degradation.

Relevant Articles and Policies:

• Constitutional Framework: Right to a clean environment as part of the Right to Life under Article 21.
• Government Initiatives: CSIR-backed initiative for the development and certification of low-emission firecrackers as part of broader efforts to address air pollution.
• Net-Zero Goals: Aligning firework regulations with climate change mitigation strategies, contributing to international commitments for net-zero emissions.

Recommendations for Further Action:

• Continue developing cleaner cracker formulations while balancing cultural traditions with environmental responsibility.
• Advocate public awareness campaigns to highlight the impacts of air quality on health and promote responsible choices during celebrations.
