Guided story
How dependent is India on coal?
In 2025, coal generated 70.8% of India's electricity. But the real story is more than one number: absolute coal use keeps rising, imports matter, and the climate cost is growing.
How much of India’s electricity comes from coal?
In 2025, coal-fired power plants produced 1,474.15 terawatt-hours (TWh) of electricity. That was 70.82% of all electricity generated in India, which totalled 2,082.82 TWh. A terawatt-hour is a huge unit, one TWh is a trillion watt-hours. Think of it as the output of a 1,000-megawatt power plant running for about 41 days. Coal’s share in the generation mix is the most direct measure of dependence. Fossil fuels together supplied 73.35%, with gas adding just 2.33%. Clean sources, including hydro, nuclear, solar, and wind, made up the remaining 26.65%. While coal’s share edged down from somewhat higher levels earlier in the century, it remains utterly dominant. This single fuel still generates more than seven of every ten units of electricity that Indians use.
How much of India's electricity is coal

In 2025, coal supplied 70.82% of India’s electricity, generating 1,474.15 TWh out of 2,082.82 TWh.
The chart displays the share of coal in India’s annual electricity generation over the full available period. The most recent year shows a coal share of 70.82%, down from higher levels in earlier decades but still commanding. Electricity generation is measured in terawatt-hours (TWh), a unit that counts each unit of electrical energy produced. A high share means that for every 100 units of electricity you use at home, about 71 come from coal. The rest comes from hydro (8.55%), nuclear (2.59%), solar, wind, and gas. The visual makes it easy to see that coal, while slowly losing some share, remains the backbone.
How can coal’s share fall while total coal generation keeps rising?
A falling share can be deceiving. The absolute amount of coal-fired electricity has not dropped; it has grown. In 2025, coal plants generated 1,474.15 TWh, a number that, as the chart reveals, has risen over the years. What has changed is that clean generation grew even faster. Solar and wind additions, in particular, expanded total supply so rapidly that coal’s slice of a much larger pie got smaller, even though the slice itself got larger. In 2025, clean sources produced 554.81 TWh. The gap between coal and clean generation is still huge, but the trend matters: if electricity demand keeps climbing fast, coal output can rise for years even as its percentage share declines. The chart shows this dynamic, coal is not fading; it is being overtaken in growth by clean energy only in relative terms.
Coal generation keeps rising

While coal's share dips, the absolute amount of coal-fired electricity has kept increasing, reaching 1,474.15 TWh in 2025.
This chart tracks the actual terawatt-hours of electricity generated from coal (orange line) and from clean sources (green line) each year. It reveals that even as the percentage share of coal declined, the TWh output rose steadily. In 2025, clean generation reached 554.81 TWh, which is growing faster than coal, but coal is still more than double that figure. Because total electricity demand jumps every year, both lines can go up while the share shifts. The visual answers the puzzle: more renewables do not automatically mean less coal in absolute terms, they mean coal’s portion shrinks relative to a bigger whole.
Where does India get its coal?
Almost all the coal India burns comes from within its own borders. In 2024, domestic production stood at 1.01 million thousand metric tons. That is a huge leap from 1,10,224.87 thousand metric tons in 1980. Yet imports have grown even faster, from just 550 thousand metric tons in 1980 to 2,32,811.51 thousand metric tons in 2024. Though domestic output dwarfs imports, the imported portion is not trivial, it has grown by a factor of over 400 since 1980. The chart plots both lines, making the trend clear: India is producing more coal than ever, but it is also buying more abroad, adding a layer of import exposure to its coal dependence.
Coal: home production vs imports
2024 · latest point
India mines most of its own coal (1.01 million thousand metric tons in 2024), but imports have grown to 2,32,811.51 thousand metric tons.
Two lines show domestic coal production and coal imports over time, both in thousand metric tons. Domestic output has climbed steeply from 1,10,224.87 thousand metric tons in 1980 to over a million in 2024. Imports, though much smaller in absolute terms, have risen even more dramatically, from just 550 thousand metric tons in 1980 to 2,32,811.51 thousand metric tons in 2024. The data does not reveal why imports have grown so fast, but the contrast with domestic production is clear. The gap between the lines remains large, but the trend shows a growing role for foreign coal in India's supply.
How much coal does India use beyond electricity?
The electricity sector is the biggest burner of coal, but it is not the only one. Steelmaking, cement production, and other industries consume large volumes. The total energy consumption from coal, across all uses, reached 21.8 quadrillion British thermal units (Btu) in 2024. That is twelve times the 1.82 quadrillion Btu consumed in 1980. While Btu is an unfamiliar unit (one quadrillion Btu is enough to power about 10 million Indian homes for a year), the direction is what matters: total coal use has risen relentlessly. This broader coal footprint means that even if power-sector coal plateaus, overall dependence could persist. The chart shows this long climb, reminding us that coal is not just about electricity.
Total coal use, beyond just power

India's total coal consumption reached 21.8 quadrillion Btu in 2024, a twelve-fold rise from 1.82 quadrillion Btu in 1980.
This line chart shows the total primary energy consumption from coal, measured in quadrillion British thermal units. It captures all the coal burned, for power, steel, cement, and any other industrial use. The unit is large and unfamiliar: one quadrillion Btu is roughly the energy in 28 billion litres of petrol. The trend since 1980 is unmistakably upward. The 2024 value of 21.8 quadrillion Btu highlights that coal’s role extends well beyond the power sector. Even if India were to stop using coal for electricity tomorrow, industrial demand would keep the fuel in play.
What is the climate cost of India’s coal use?
Coal is the most carbon-intensive fossil fuel. In 2024, India’s coal and coke consumption emitted 2,117.06 million metric tonnes of CO₂, up from 175.18 million metric tonnes in 1980. That twelve-fold rise tracks the growth in coal use. Within the power sector alone, coal accounted for 95.92% of emissions, or 1,338.09 million metric tonnes out of total power-sector emissions of 1,394.95 million metric tonnes in 2025. The line in the chart rises steeply, a direct consequence of India’s coal dependence. For climate, the scale of this dependence means that even rapid renewable additions will struggle to bend the emissions curve downwards quickly.

Coal and coke emissions hit 2,117.06 million metric tonnes CO₂ in 2024, a near-twelve-fold jump from 175.18 million tonnes in 1980.
This chart traces the annual carbon dioxide emissions from the combustion of coal and coke in India. The line rises in lockstep with coal consumption: from 175.18 million metric tonnes in 1980 to 2,117.06 million metric tonnes in 2024. The power sector is the chief culprit, responsible for 1,338.09 million tonnes of that in 2025, about 95.92% of its own emissions. Coal is the most carbon-intensive fossil fuel, so the steep rise in emissions mirrors the growth in coal use. Any discussion of decarbonisation must confront this line.
