In the 1300’s in what is now the U.S. Southwest, the Hopi Indians used coal for cooking, heating and to bake the pottery made from clay. In 1673, coal was later rediscovered in the United States by explorers.
In the 1700s, the English found that coal could be burned hotter and cleaner than wood charcoal. However, coal’s dominant place as an energy source did not come about until the Industrial Revolution when new technologies demanded higher amounts of energy. Archeologists have also found evidence of coal use by the Romans in England in the second and third centuries (100-200 AD).
