According to the U.S. Department of Energy, coal has been used as a source of heat as far back as early humans walked the earth. It wasn't until the 1700s that the English discovered that coal could be used as a cleaner energy source compared to the wood charcoal that they were currently using. The Industrial Revolution in the 1700s brought coal to the forefront of energy supply with the endless amount of inventions that required coal to run.
