Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.

High Quality Coal Releases A Lot of Heat. Anthracite coal burns efficiently with no odor or smoke and by heating water rather than air, a coalburning furnace loses less heat. To get an idea of how much highquality coal can produce, one ton of anthracite coal equals about 8,200kilowatt hours of electricity.

Coal has a bad name: Accidents in coal mines; mountaintop removal mining; acid rain; and, especially, global warming. Burning coal produces more greenhouse gases than other fossil fuels for the same amount of energy. But coal's supporters are quick to point out that there is no ready alternative. Coal provides nearly half of America's electricity.
