Coal Supplies 79 Percent of India's Domestic Energy Despite Renewable Expansion

Coal continues to account for nearly 79 per cent of India's domestic energy supply even as renewable energy capacity and generation grow rapidly, with heavy reliance on imported oil and gas exposing the country to global price volatility. Balancing energy security with climate targets is characterised as the defining challenge for India's energy sector in the coming decade.

India's energy demand is rising sharply, driven by rapid urbanisation, industrial expansion and growing household electricity consumption. Despite significant investment in renewable energy, coal remains the dominant fuel in the domestic energy mix, providing nearly 79 per cent of total energy supply. Solar and wind capacity have grown substantially, but the pace of clean energy expansion has not been sufficient to displace coal's structural role in baseload power generation, particularly as peak demand increases.

India's dependence on imported oil and natural gas creates persistent economic vulnerability to global energy price movements, as demonstrated by recent supply disruptions linked to geopolitical conflict in West Asia. Higher import costs translate directly into domestic fuel prices, inflation and current account pressures. The government has responded with short-term measures including excise duty cuts and fuel rationing, but structural energy security requires a faster transition to domestically sourced renewable power.

Analysts emphasise that India's energy trajectory in the 2025-2035 period will be critical in determining whether the country meets its Nationally Determined Contribution targets, including the commitment to achieve 60 per cent of installed electricity capacity from non-fossil sources by 2035. Accelerating coal-to-renewable substitution, expanding electricity storage, building cross-border power connectivity and developing demand response mechanisms are all identified as necessary components of a viable transition strategy.
