Describe the benefits of deriving electric energy from sunlight in contrast to the conventional energy generation. What are the initiatives offered by our Government for this purpose?

In short

Solar power is cheaper, cleaner, faster to build and more decentralised than coal-based generation, and the government backs it through the National Solar Mission, solar parks, PM-KUSUM, PM Surya Ghar and a manufacturing PLI. Solar tariffs fell from ₹6.17/kWh in 2014-15 to ₹2.15/kWh in 2024-25.

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
India's solar capacity rose from 2.82 GW in March 2014 to about 129 GW in 2025 (PIB). Photovoltaic cells turn sunlight directly into electricity with no fuel, turbine or smokestack.
Benefits of Solar Power over Conventional Generation
•

Cheaper electricity

Solar tariffs fell from ₹6.17/kWh in 2014-15 to ₹2.15/kWh in 2024-25 (PIB), below most new coal power, because the fuel is free.

•

Energy security

Every solar unit cuts coal and fuel imports and exposure to price shocks like the 2022 fuel crisis.

•

Power at the point of use

Rooftop panels and solar pumps avoid transmission losses and replace diesel and kerosene.

Government Initiatives for Solar Energy
•

Mission and alliance

The National Solar Mission (2010) set a 100 GW target, and India co-founded the International Solar Alliance at COP21 in 2015.

•

Parks and pumps

55 solar parks of 40 GW are sanctioned across 13 states, and PM-KUSUM has backed about 9.2 lakh solar pumps (PIB, 2025).

•

Rooftops

PM Surya Ghar (2024) reached nearly 24 lakh homes by December 2025 towards one crore.

•

Manufacturing

The PLI scheme for high-efficiency modules and the ALMM list doubled module capacity from 38 GW to 74 GW in a year (PIB, 2025).

Way Forward
•

Storage and supply chain

Only about 5.5 GW of storage backs 243 GW of renewables, and India has no polysilicon capacity (Standing Committee on Energy, 2025).

Conclusion
Solar gives India cheaper, cleaner and more secure power. With storage and a domestic supply chain, it can carry India towards energy independence and a Viksit Bharat by 2047.
