Global Coal Timeline 1760–2026: Industrial Revolution to Record Coal Demand

Solar panels are going up faster than ever. Wind farms keep expanding. Battery factories are multiplying across three continents. And yet in 2026, the International Energy Agency now expects global coal demand to reach roughly 8.94 billion tonnes — a new record, up 1.2% on the year, and a sharp reversal from forecasts that had expected demand to flatten out. That does not mean the energy transition has stalled. It means clean power and fossil power can both be growing at the same time, for reasons that have almost nothing to do with whether solar and wind “work.”

How can both be true? Because the energy transition has two separate jobs. Job one is supplying new energy demand with cleaner sources. Job two is replacing existing fossil-fuel generation and industrial use that is already running. If clean-energy growth is mostly absorbed by job one — covering new demand — there is little left over to do job two, and coal can stay high or even rise. Coal declines structurally only once low-carbon generation growth persistently outruns new demand by enough to start displacing existing coal output, not just matching it.

This is a conceptual relationship, not a complete power-system model — real grids also depend on hourly timing, transmission, storage duration and weather.

Coal is not one product with one use. The IEA and industry bodies split it into two broad categories with very different roles, markets and price benchmarks.

Decarbonising electricity and eliminating coal from steelmaking are two separate technical challenges, on different timelines, using different technologies. A country can make real progress on one while barely starting on the other.

1. Earlier outlook: renewables growth expected to hold coal demand flat
2. Middle East conflict disrupts Strait of Hormuz shipping
3. LNG supply tightens sharply
4. Natural-gas prices rise across Europe and Asia
5. Generators with spare coal capacity switch fuel toward coal
6. IEA revises 2026 coal forecast upward to a record 8.94 billion tonnes

Almost no coal itself moves through the Strait of Hormuz — it is a gas and oil chokepoint. The link to coal runs entirely through price: disrupted LNG shipments make gas scarcer and more expensive, so wherever a power system has both gas-fired and coal-fired plants with capacity to spare, coal generation becomes the cheaper option and runs more. That single mechanism, repeated across several gas-importing economies, was enough to turn an expected plateau into a fresh record.

This fuel-substitution chain explains 2026 far better than simply saying “the war increased coal demand.” It requires a country to already have both gas-fired and coal-fired generation capacity, and for coal plants to have room to run more without hitting emissions or capacity limits. Countries without that spare coal capacity see gas prices rise without any coal response at all.

China is both the world’s largest coal consumer and largest coal producer, and simultaneously the world’s largest builder of solar and wind capacity. In 2025 it added over 300 GW of solar and more than 100 GW of wind — both records for any country in history. Its electricity demand rose about 5% that year. Yet coal-fired electricity generation still fell 1.9%, the first annual decline since 2015, because the new demand was covered by wind, solar, nuclear and hydro rather than coal.

So how can China build record solar and still use so much coal overall? Because electricity generation is only part of China’s coal demand. Coal also feeds steel production, cement, and a fast-growing chemicals sector that converts coal into products normally made from oil or gas. In 2026, mine-safety shutdowns after the Shanxi accident cut Chinese production sharply, yet China still produced over 4.62 billion tonnes — more than half of global output. This is not a story of China “refusing” to transition; it is a story of new industrial demand, energy-security caution and system flexibility all existing alongside a genuinely fast renewable buildout.

India’s coal consumption is forecast to rise 4.2% in 2026 to roughly 1,353 million tonnes, with domestic production around 1,095 million tonnes as the country works to reduce import dependence. This growth is tied directly to India’s expanding economy, rising industrial output, growing air-conditioning demand during hot summers, and an electricity system still building out transmission and storage capacity. Monsoon strength also matters: a weak monsoon means less hydropower, pushing more generation onto thermal plants.

India is simultaneously one of the fastest-growing large markets for solar power and grid modernisation — see AiTimeline’s India Smart Grid Timeline for how the grid itself is being rebuilt to handle more renewables. Framing India as simply “refusing to quit coal” misses the point: it is balancing development, reliability, affordability and emissions commitments simultaneously, the same trade-off every industrialising economy has faced.

This is a common but misleading question. Solar panels generate electricity; conventional blast-furnace steelmaking needs coke — derived from metallurgical coal — for three things solar cannot directly provide: intense heat, structural support inside the furnace, and the chemical reduction reaction that strips oxygen from iron ore to leave metallic iron. Electricity alone does not perform that chemical step.

That does not mean coal is required for steel forever. Alternative routes exist and are scaling: recycled scrap steel melted in an electric-arc furnace (EAF), direct-reduced iron (DRI) made with natural gas, and emerging hydrogen-based DRI that could eventually run on renewable electricity via electrolysis. Carbon capture (CCUS) on conventional blast furnaces is another pathway under development. Roughly seven in ten tonnes of steel worldwide are still made via the traditional coke-based blast-furnace route, which is why steel decarbonisation is often slower and more capital-intensive than power-sector decarbonisation — a genuinely separate challenge from replacing coal in electricity generation.

The IEA currently expects 2026 global coal demand to hit a record while global coal production actually declines around 0.7% — a seeming contradiction that trade and inventories resolve. China’s Shanxi-driven mine shutdowns cut supply sharply in mid-2026, but global production is still projected to stay above 9 billion tonnes for a third consecutive year. The difference between what is mined and what is burned in any single year is absorbed by drawing down stockpiles and by international trade — production and consumption never have to move identically within one calendar year.

Coal demand moves with the weather, not just with policy. Hot summers push up air-conditioning load and electricity demand. Weak monsoon or dry seasons reduce hydropower output across parts of Asia, shifting generation onto thermal plants including coal. Strong hydro years can push coal generation down even without any new renewable capacity being added. Weak wind years mean other sources, sometimes coal, fill the gap. This is why year-to-year coal demand can swing even while the underlying clean-energy buildout is proceeding on a steady, structural upward path.

Coal combustion is the single largest source of global energy-related CO₂ emissions, ahead of oil and natural gas, because it emits more carbon dioxide per unit of energy released than either. Global energy-related CO₂ emissions reached a record of roughly 38.4 billion tonnes in 2025. Beyond CO₂, coal mining also releases methane, a potent greenhouse gas, and coal combustion contributes to local air pollution. These facts sit alongside, not against, everything else in this article: coal use can be high for structural economic reasons while also being the leading driver of energy emissions.
