Explain briefly the ecological and economic benefits of solar energy generation in India with suitable examples.

Approach · directive: “explain”

What it asks · Set out, with Indian examples, how solar power helps the environment and the economy.

The question has 2 parts — answer each

  1. Explain the ecological benefits of solar energy generation in India, with examples
  2. Explain the economic benefits, with examples

Open with · With about 300 sunny days a year in much of the country, solar power has become the leading edge of India's energy transition.

Cover

  • Ecological: near-zero operating emissions; displaces coal and supports India's NDC and net-zero-by-2070 goal.
  • Ecological: cuts air pollution and saves water compared with thermal plants; canal-top and floating solar reduce land use and evaporation.
  • Economic: competitively bid tariffs lower power costs; less dependence on imported fuel improves energy security.
  • Economic: PM-KUSUM solar pumps cut farmers' diesel costs and let them sell surplus power; PM Surya Ghar supports rooftop solar for households.
  • Economic: jobs in installation and maintenance; PLI for high-efficiency modules builds domestic manufacturing; large parks such as Bhadla and Pavagada.
  • Social and strategic: electrification of remote areas; India's leadership of the International Solar Alliance.

Close with · Solar power aligns growth with climate goals; storage, grid integration and domestic supply chains are the next frontier.

Model answer · 210 words (UPSC limit 150) · Minimalist IAS

With roughly 300 sunny days a year over most of the country, India's installed solar capacity rose from 2.82 GW in 2014 to over 100 GW by January 2025, making solar the leading edge of its energy transition.

Ecological benefits

  • Near-zero operating emissions: every solar unit displaces coal power, advancing the NDC and the net-zero-by-2070 pledge; non-fossil sources reached 50% of installed capacity in July 2025.
  • Cleaner air and water: no smoke, ash ponds or fly ash, and negligible water use compared with thermal plants' cooling.
  • Land and water saved: canal-top and floating solar cut land take and curb evaporation; rooftops use no new land.

Economic benefits

  • Cheaper power: competitive bidding has pushed tariffs down, lowering costs for discoms and industry, while less imported fuel strengthens energy security.
  • Farm incomes: PM-KUSUM solar pumps replace diesel and let farmers sell surplus power; PM Surya Ghar subsidises household rooftops, cutting bills.
  • Jobs and industry: installation and maintenance employment; the PLI scheme for high-efficiency modules builds domestic manufacturing; mega-parks at Bhadla (Rajasthan) and Pavagada (Karnataka) anchor investment.
  • Strategic dividend: electrification of remote areas, and leadership of the International Solar Alliance brings diplomatic and export gains.

Solar aligns growth with climate goals; storage, grid integration and a home-grown supply chain are the next frontier.

Written by Minimalist IAS from facts checked at source (how we verify) — a little fuller than exam length, so every part of the question is covered; in the hall, keep the structure and trim the detail. UPSC publishes no model answers: compare your structure and coverage with this, then write your own.
