Q. 2025 marked the first year when the entire growth in global electricity demand was met by renewables. Critically analyse the implications of this milestone for India's energy security and climate commitments. (15 marks, 250-350 words)

Ember's Global Electricity Review 2026 records that clean generation rose by 887 TWh in 2025 against demand growth of 849 TWh, pushing renewables (~34%) past coal (~33%) for the first time in a century [1]. For India, this is a genuine structural opening — but one confined to the power sector.

Gains for energy security - The global fall was driven by India and China, where fossil generation declined together for the first time this century [1] — evidence that demand growth need not translate into import growth. - India added 44.5 GW of renewable capacity in 2025 (till November), nearly double the previous year, and crossed 50% non-fossil installed capacity in June 2025, five years ahead of its NDC [2]. - Domestically generated solar and wind are price- and geopolitics-insulated, unlike imported hydrocarbons.

Gains for climate commitments - Substitution, not demand destruction, validates the 500 GW non-fossil capacity by 2030 pathway [3]. - Flagship schemes — National Green Hydrogen Mission and PM Surya Ghar: Muft Bijli Yojana, the world's largest rooftop solar programme — extend the transition to industry and households [5]. - Falling coal burn yields co-benefits in PM2.5, SO₂ and NOₓ abatement.

Critical limits - The milestone covers electricity, not total energy. India's crude import dependence touched a record 88.7% in 2025-26 [4]; transport and petrochemicals remain untouched, so Strait of Hormuz-type shocks still bite. - Installed capacity ≠ generation: low capacity utilisation means coal still supplies the bulk of actual units. - Grid, storage and discom finances remain the binding constraints; without transmission and battery build-out, curtailment will cap gains.

The 2025 reversal proves that renewables can now carry incremental demand at scale, but India's advantage will be realised only when capacity converts into dispatchable generation. Prioritising storage, transmission corridors and discom reform — alongside green hydrogen for hard-to-abate sectors — would let India meet its Paris commitments while turning energy security from an import problem into a domestic manufacturing opportunity.
