. Coal was the dominant power source in the United States in the late 1800s and early 1900s, and although in rapid decline it remains a significant source of energy in 2019.
Coal became the largest source of energy in the 1880s, when it overtook wood, and remained the largest source until the early 1950s, when coal was exceeded by petroleum. Coal provided more than half of the nation's energy from the 1880s to the 1940s, and from 1906 to 1920 provided more than three-quarters of US energy.

At the start of the 19th century, coal mining was almost all

. In 1810, 176,000 short tons of bituminous coal, and 2,000 tons of anthracite coal, were mined in the United States. American coal mining grew rapidly in the early 1820s, doubling or tripling every decade. Anthracite mining overtook bituminous coal mining in the 1840s; from 1843 through 1868, more anthracite was mined than bituminous coal. But the more limited deposits of anthracite could not satisfy the increasing demand for coal; from 1869, bituminous coal was the dominant grade of coal mined. Another reason for the decline in anthracite was the decline in its use in iron smelting, where it was displaced by
coke in blast furnaces after the Civil War. Coke stayed hard and porous and was able to support the heavy column of ore and fuel in the large blast furnaces it enabled.

was valued for household use because it burns cleanly with little ash. It was also used in the early foundries of Philadelphia, New York, Newark and Allentown. The rich Pennsylvania anthracite fields were close to the big eastern cities, and nearly every major railroad in the Eastern United States such as the
Reading Railroad, Lehigh & Erie, Central Railroad of New Jersey, Pennsylvania Railroad and
Delaware and Hudson Railroad, extended lines into the anthracite fields. Many railroads began as mining company shortline railroads. By 1840, annual hard coal output had passed the million-short ton mark, and then quadrupled by 1850, and as it grew it pushed railroad construction, mining and steel production in a synergistic symbiosis.

Mining history by state
Pennsylvania
* The first anthracite coal was mined in 1768 by Obadiah Gore, a blacksmith, in the Wyoming Valley (Kingston, PA). This was in the very early days of colonists settling in Northeastern Pennsylvania from Connecticut. The Susquehanna Company was an expedition that came into the Wyoming Valley and established the first 5 towns: Pittston, Plymouth, Wilkes-Barre, Nanticoke (later Hanover), and Forty Fort (later Kingston).
* Nicholas Scull, a famous colonial surveyor issued a map in Philadelphia in 1770 that showed the location of 5 coal mines all in Schuylkill County: York Farm (Pottsville), near Silverton Junction, near Llewellyn, and 2 more around Ashland.
* By 1807, fifty tons of coal was being sold by the Smith Brothers out of Plymouth, Pennsylvania. They exported it via barge on the Susquehanna River to Columbia, PA (Lancaster County).
* In February 1808, Wilkes-Barre resident, Jesse Fell, experimented with a successful open-air grate that kept anthracite burning in low-yield household fires. The Smiths seized on Fell's discovery and returned to Columbia with more coal and instructions for local blacksmiths on preparing the grates.
* Bituminous coal was first mined in Pennsylvania at "Coal Hill" (Mount Washington), just across the Monongahela River from the city of Pittsburgh. The coal was extracted from drift mines in the Pittsburgh coal seam, which outcrops along the hillside and transported by canoe to the nearby military garrison. By 1830, the city of Pittsburgh consumed more than 400 tons per day of bituminous coal for domestic and light industrial use.

In addition to the poor economic condition, safety in the mines was a great concern.

Employment
Coal-mining employment increased rapidly in the late 1800s and early 1900s, and peaked in 1923 at 798,000. Since then, the number of miners has fallen considerably since, due to mechanization. By 2019 it had fallen below 55,000.

's Kanawha field had to be escorted by armed guards. The same machine introduced at a mine in Illinois was operated at a slow speed because the superintendent feared labor troubles.
Despite resistance, mechanization replaced more and more laborers. By 1940, over 2/3 of coal loaded in the large West Virginia fields was done by machine. With the increase of mechanization came much higher wages for those still employed, but hard times for the former miners because there were very few other jobs in or near the camps. Most moved to the cities to find work, or back to the hills where they started.

In 1987 Wyoming became the largest coal producing state. As of 2014, all but one out of the 18 coal mines in Wyoming were strip mines. Wyoming's coal reserves total about 69.3 billion tons, or 14.2% of the U.S. coal reserve.
Coal is used primarily to generate electricity, but the rapid drop in natural gas prices after 2010 created severe competition.
