1700s - Coal Begins to Displace Use of Other Energies
"The great shift in population and industry that took place in the eighteenth century was due to the introduction of coal as a source of mechanical power, to the use of new means of making that power effective - the steam engine - and to new methods of smelting and working up iron.
