Q. Despite rapid growth in renewable energy potential, coal continues to dominate India's primary energy supply. Critically examine the reasons and policy implications. (15 marks, 250-350 words)

India's assessed renewable energy (RE) potential more than doubled to 47,04,043 MW as on 31 March 2025, yet coal's absolute energy supply rose from 3,87,761 KToE (FY 2015-16) to 5,52,315 KToE (FY 2024-25) within a Total Primary Energy Supply of 9,32,816 KToE growing at 2.95% [1][2]. Coal's persistence is structural, not accidental.

Reasons for continued coal dominance - Demand outpacing substitution: per-capita consumption rose from 15,296 MJ to 18,096 MJ (FY 2015-16 to FY 2024-25); RE additions largely meet incremental demand rather than displace coal [1]. - Potential is not capacity: against theoretical RE potential in millions of MW, installed RE stood at 274.68 GW — solar 150.26 GW, wind 56.09 GW [2]. - Intermittency and baseload: solar (~71% of potential) is variable; without storage, coal supplies round-the-clock reliability that kept power shortage at 0.03% [2][3]. - Geographic mismatch: over 70% of RE potential lies in six states — Rajasthan, Maharashtra, Gujarat, Andhra Pradesh, Karnataka, Madhya Pradesh — while demand centres lie elsewhere, requiring transmission build-out [2]. - Lock-in effects: sunk investments in plants, railway freight cross-subsidy and coal-linked livelihoods raise transition costs.

Policy implications - Financing: the 2026 edition's new "credit flow to energy sector" data enables targeted capital-flow monitoring for transition finance [1]. - Grid and storage: inter-state transmission corridors and battery/pumped storage become the binding constraint, not generation capacity. - Market reform: cost-reflective tariffs and open access, as proposed in the Electricity (Amendment) Bill, 2026, improve DISCOM capacity to absorb RE [3]. - Just transition: coal-bearing districts need diversification before capacity retirement. - Statistical governance: energy balance tables and Sankey diagrams enable evidence-based sectoral targeting [1].

Coal dominance reflects a transition in progress rather than a stalled one — RE is scaling faster than any comparable economy while coal underwrites reliability. Sequencing storage, transmission and distribution reform ahead of coal retirement, in step with the Net Zero 2070 pledge, converts abundant potential into dependable supply and secures energy justice alongside energy security.
