Coal: Past, Present and Future
The use of coal in the U.S. grew with surging electric demand, increasing by an average annual rate of 3% from 1960 through 1990. But it was not until 2007 that coal consumption peaked in the U.S. Since that time, coal use for electricity generation has decreased as natural gas and renewable energy sources have been deployed.

IEA: Global coal demand set to remain at record levels in 2023
Coal consumption in 2022 rose by 3.3% to 8.3 billion t, setting a new record, according to the IEA's mid-year Coal Market Update. In 2023 and 2024, small declines in coal-fired power generation are likely to be offset by rises in industrial use of coal, the report predicts, although there are wide variations between geographic regions.
