About ACAAs Production and Use Survey The American Coal Ash Association has conducted a survey quantifying the production and use of coal combustion products in the United States each year since 1966. Data is compiled by directly surveying electric utilities and utilizing additional data produced by the U.S. Energy Information Administration.
By 2030, the range of projected coal use in the United States broadens considerably, from about 70 percent above to 50 percent below current levels. At present, coal imports and exports represent small fractions of total U.S. coal production and use. Projections indicate that imports and exports are expected to remain relatively small.

Over the next 10 to 15 years (until about 2020), coal production and use in the United States are projected to range from about 25 percent above to about 15 percent below 2004 levels, depending on economic conditions and environmental policies.
Black coal is also used to produce coke (metallurgical or coking coals), which is mainly used in blast furnaces that produce iron and steel. Black coal is used also in other metallurgical applications, cement manufacturing, alumina refineries, paper manufacture and a range of industrial applications.
Coal mined in the Appalachian coal region is primarily used for steam generation for electricity, metal production, and for export. Interior Coal Region Texas is the largest coal producer in the Interior Coal Region, accounting for almost one-third of the regions coal production. Mid-sized surface mines. Mid- to large-sized companies.
Some power-generating companies not only use coal for electricity generation but also own coal mines or are involved in coal production themselves. Other companies generate electricity from purchased coal. International context. Global coal production in 2019 is estimated at 7.9 billion tonnes, increasing by 116 million tonnes from 2018.
Coal has been one of most valuable natural resources since the 1300s when the Hopi Indians used it for the first time. European settlers began to use coal in the late 1740s and as immigration to the US grew and energy demand increased, coal production quickly climbed from 9.3 million tons in 1850 to 750 million in 1918.
Metallurgical coal is an essential ingredient in the production of steel, one of the most widely used building materials on earth. It takes around 770 kilograms of coal to make one ton of steel with approximately 70 per cent of global steel produced in basic oxygen blast furnaces.
