Coal — The Essentials

How much coal humanity has burned, how fast we're mining it, how much is left underground — and why it matters for climate.

All ~1,082 Billion Tonnes of Known Coal — Mined vs. Remaining
~16% Consumed
~84% Reserves
Consumed
Coal already burned throughout human history — primarily for electricity generation, steelmaking, and industrial heat.
~200 Bt historical
~200 billion tonnes
Total consumed
Mostly since 1900; ~40% of all CO2 from fossil fuels
8.82 billion tonnes
2024 output
China leads (~4.4 Bt, 50%), followed by India (~1.08 Bt)

Reserves
Coal still underground in economically recoverable deposits — including anthracite, bituminous, sub-bituminous, and lignite grades.

Mainly from reassessments in Indonesia (+4 Bt), India (+6 Bt) and others — driven by updated geological surveys & economic viability reclassification

But coal faces a different constraint: climate. Coal is responsible for ~40% of global energy-related CO2 emissions. The "120 years" figure assumes we keep burning — which physics says we can't.

Global coal demand hit an all-time high of ~8.77 billion tonnes in 2024. Unlike metals, coal is a consumable fuel — once burned, it's gone forever.

⚡ Power Generation ~5.7 Bt (65%)

Electricity and heat generation. Coal still supplies ~36% of global power — down from 40% in 2010, but stubbornly persistent in Asia.

🏭 Steel & Iron ~1.32 Bt (15%)

Metallurgical (coking) coal for steelmaking. No scalable commercial substitute exists yet — hydrogen-based steel is still ~2-3× more expensive.

🏗️ Cement & Industry ~1.05 Bt (12%)

Cement production, chemicals, and other industrial processes. Some substitution possible with biomass or waste fuels.

🏠 Residential & Other ~0.7 Bt (8%)

Home heating, small-scale industry, and other uses. Declining rapidly in developed countries but still significant in developing regions.
