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.
In 2025, coal supplied 70.82% of India’s electricity, generating 1,474.15 TWh out of 2,082.82 TWh.

About this chart
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.
Why this chart This is the primary measure of coal dependence in the power sector.
How to read it Look at the percentage label for the latest bar and follow the share line across years.
Watch out Do not confuse a small drop in share with coal becoming unimportant, it still dominates.
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 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.

About this chart
This chart tracks the actual terawatt-hours of electricity generated from coal (ochre line) and from clean sources (black 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.
Why this chart It resolves the paradox of falling share with rising tonnage.
How to read it Watch the two trend lines; if the clean-sources line rises faster than the coal line, coal's share drops even if both increase.
Watch out Assuming that a falling share means coal generation is going down, it isn't.
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 dependencecoal dependenceReliance on coal as the main fuel for making electricity or running industries. It is measured by looking at the share of coal in the mix, the absolute amount of coal burned, and how much of that coal is imported. A country can be dependent even if its coal share is falling, provided the total amount keeps rising.This page answers exactly this question, examining dependence from several angles..

About this chart
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.
Why this chart It highlights import exposure as a dimension of dependence.
How to read it Compare the scale of the two lines and notice the steep rise in imports relative to their starting point.
Watch out Thinking imports are negligible, while small relative to production, they have grown by a factor of 400 and are an important part of the 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

About this chart
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.
Why this chart It widens the lens from electricity to the full economy.
How to read it Follow the line upward; the height at the end tells you the latest total coal burn.
Watch out Not confusing this with electricity generation, it includes all energy forms from coal.
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.

About this chart
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.
Why this chart It directly links coal dependence to climate change.
How to read it Observe the slope; a steeper rise means faster emissions growth.
Watch out Thinking this is total national emissions, it is only from coal and coke.
Tell me what this means, bro
Okay, but what does this actually mean, macha?
Think of India's electricity like a big thali. The largest roti on that plate is coal, and it isn't getting smaller. Even though we are adding solar panels and wind turbines at speed, the country's hunger for power is growing so fast that coal consumption keeps going up every year. Coal is not just for electricity; industries like steel and cement also use it, as reflected in the total coal consumption number. This scale is not about blame; it is about the size of the challenge. The data shows coal use is expanding across sectors, so reducing dependence will take sustained effort.
India's coal use is not shrinking, it is expanding across all sectors, making the clean-energy race a marathon, not a sprint.॥
Plain English concepts
terawatt-hour (TWh)
One terawatt-hour is a trillion watt-hours. Imagine a 1,000-megawatt power plant, like a big coal unit, running at full capacity for about 41 days; that produces roughly one TWh. It is the standard large unit for measuring annual electricity generation. A TWh does not tell you how many homes are lit; it tells you the total electrical energy produced.
All generation numbers on this page are in TWh, so we can compare coal with hydro, solar, and other sources directly.
coal dependence
Reliance on coal as the main fuel for making electricity or running industries. It is measured by looking at the share of coal in the mix, the absolute amount of coal burned, and how much of that coal is imported. A country can be dependent even if its coal share is falling, provided the total amount keeps rising.
This page answers exactly this question, examining dependence from several angles.
import dependency
The portion of a country's coal supply that comes from abroad. If many coastal power plants or steel mills rely on foreign coal because local mines cannot supply the right grade, then sudden global price spikes or shipping disruptions can hit the economy. A high import share adds a vulnerability layer to dependence.
Understanding how much coal India imports is a key part of understanding its overall coal dependence.
carbon intensity
The amount of carbon dioxide released for every unit of electricity generated, usually measured in grams of CO₂ per kilowatt-hour (gCO₂/kWh). Coal has the highest carbon intensity among fossil fuels, meaning it produces the most CO₂ per unit of energy. A high-carbon-intensity grid means that using more electricity directly adds more emissions.
While not charted directly, the concept underlies the link between coal dependence and emissions: coal's high carbon intensity means that more coal automatically means higher CO₂ output.
