Coal mining in the United States is an industry in transition. Production in 2017 was down 33% from the peak production of 1, million tons (about million metric tonnes) in 2006. Employment of 50,000 coal miners is down from a peak of 883,000 in 1923.
Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.
The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained .
Uses: It is mainly used as a fuel in industries situated near coal processing plants. Earlier, it was used as a source of light. In the year 1820, it was used in London for the first time as street lighting. Now, it is more commonly used to provide heat for domestic and industrial purposes.
