In the interactive chart here we see coal production by country. This has been converted into primary energy equivalents (i.e., terawatt-hours of energy) for comparability across our other data on energy. Note that this measures coal production, not consumption. Many countries consume energy from coal in their energy supply.

The chart to the left shows production for 2011 through 2021. The price per ton at the various sites depends on the quality of coal (heating value, moisture content, sulfur and ash content, etc.) but an average for the Fiscal Year 2020 was $20.33 per ton making the value of that coal just under $538 million.

Coal is a fossil fuel and has been generating electricity in Great Britain since the industrial revolution. But the decarbonisation of the grid will see it phased out by the end of 2024. In 1882, Thomas Edison's Holborn Viaduct coal plant started generating electricity for public use. It was the first power station of its kind, burning enough coal to provide energy to …
