Coal is America’s most abundant energy source. The United States has more coal within its own borders than any other country – some 272 billion tons. That is approximately one quarter of the world’s known recoverable coal reserves.
The energy content of America’s coal is equivalent to a trillion barrels of oil – roughly comparable to the world’s entire known oil reserves. According to the U.S. Department of Energy, at the current rate of consumption, coal can meet America’s domestic demand for more than 200 years.
More than 120,000 people work to produce coal in 27 states, at almost 1,400 mines.
