Steam

Steam engines use coal to heat the engines which were full of water therefore creating steam. the pressure of that steam was used to move a piston. In 1786 a Scottish inventor named James Watt made big improvements to the design of the steam engine. he made so that it was more powerful and made it burn less fuel

By the 18th century charcoal was becoming scarce and expensive in 1784 Henry Cort invented a new way of making wrought iron in a huge coal fired furnace. So it became cheaper to make iron. Well made iron was essential for some machinery in the factories
