Q6.

Explain briefly the ecological and economic benefits of solar energy generation in India with suitable examples. (Answer in 150 words)

How to Approach

The approach should be to divide the answer into two distinct sections: Ecological Benefits and Economic Benefits, as asked. For each section, list 2-3 high-impact, concise points. Ensure the points are supported by relevant, specific examples or statistics gathered, such as major solar parks or schemes, to meet the UPSC standard of being fact-based and comprehensive within the word limit. The structure must be tight to fit the 150-word constraint.

Introduction

Solar energy generation is central to India's commitment to energy transition, aiming for 500 GW of non-fossil fuel capacity by 2030 and Net Zero by 2070. As a resource that leverages India's abundant solar insolation, it offers a dual dividend by substantially mitigating environmental impact while simultaneously fostering robust economic growth and enhancing energy security, which are critical imperatives for the nation's sustainable development trajectory.

Ecological Benefits

  • Climate Change Mitigation: Solar power is carbon-neutral during operation, directly reducing Greenhouse Gas (GHG) emissions by displacing coal-based power. Example: The Bhadla Solar Park in Rajasthan prevents millions of tonnes of $\text{CO}_2$ emissions annually.
  • Water Conservation: PV solar plants consume significantly less water compared to thermal power plants, a crucial advantage in water-stressed regions.
  • Air Quality Improvement: Reduced reliance on fossil fuels cuts down on harmful pollutants like $\text{SO}_2$ and $\text{NO}_\text{x}$, improving public health.

Economic Benefits

  • Energy Security & Forex Savings: Increased domestic solar generation directly reduces the massive import bill for fossil fuels, strengthening the trade balance.
  • Cost Competitiveness: Solar tariffs have plummeted, often becoming cheaper than thermal power, leading to lower electricity costs for consumers and industries.
  • Employment & Rural Empowerment: The sector generates green jobs in manufacturing, installation, and maintenance. Example: Schemes like PM-KUSUM empower farmers by providing solar pumps and additional income from land leasing.

Conclusion

Solar energy thus serves as a powerful lever for sustainable progress in India, simultaneously safeguarding the environment by decarbonizing the energy sector and stimulating economic activity through cost reduction, job creation, and enhanced energy independence. Continued focus on grid integration and domestic manufacturing under schemes like the PLI will be key to realizing its full potential.

Key Definitions

Solar Insolation
The measure of solar radiation energy received on a given surface area over a given time, critical for assessing a region's solar power potential in India.
Levelized Cost of Energy (LCOE)
The average net present cost of electricity generation for a power plant over its lifetime, which for solar in India has seen a significant decline, making it highly competitive.

Key Statistics

India's solar energy capacity reached approximately 94.17 GW by the end of 2024, with the country aiming for 500 GW of non-fossil fuel capacity by 2030.

Examples

Bhadla Solar Park, Rajasthan

One of the world's largest solar parks, it exemplifies utility-scale deployment, preventing millions of tonnes of $\text{CO}_2$ emissions annually and utilizing arid, non-agricultural land.

Floating Solar Projects

Projects like the one at Ramagundam, Telangana, optimize land use by being installed on water bodies, thus preserving terrestrial ecosystems and reducing water evaporation.

Frequently Asked Questions

How does solar energy address India's energy security?

By relying on domestic, indigenous sunlight rather than imported coal, oil, and gas, solar power drastically reduces India's dependence on volatile international energy markets.
