For most of recorded history, energy meant biomass — wood for heat and smelting, water and wind for milling, animals and humans for muscle. Wealth meant land, because land grew the fuel and fed the workers. The first energy crisis in the Western world was a wood crisis: by the early 1600s, England had cut down so much of its forest for shipbuilding, charcoal, and heating that the kingdom was running short of trees. The cure forced upon them — burning the black rocks dug out of mines for warmth — would, within two centuries, rewrite the global ranking of nations.

Events in this era

1543

Henry VIII's shipbuilding timber crisis

By the time Henry VIII began his second war with France in 1543, English oak forests had been cut so heavily for warships, charcoal, and building timber that the Crown had to import shipbuilding wood from Baltic suppliers. England's surveyors estimated that the realm had less than half the mature oak it had held a century earlier. The Royal Navy, the foundation of every subsequent English ambition, was already constrained by an energy bottleneck — the trees that built ships and the charcoal that smelted iron came from the same forests, and there were not enough trees left for both.

England turns to coal as wood runs out

Through the early 17th century, English domestic and industrial use of coal — long known but considered a foul-smelling, peasant fuel — climbed sharply as firewood prices rose. London household coal consumption rose roughly tenfold between 1580 and 1680. Newcastle's coal exports to London expanded so much that the route became known as the 'Great Northern Coal Trade,' and the phrase 'carrying coals to Newcastle' entered English as a synonym for redundant labor. The shift was not a policy or a breakthrough — it was a forced substitution caused by a wood shortage. The fuel that would later power the Industrial Revolution started as the cheap second choice.

Coal becomes mainstream fuel out of necessity

1709

Abraham Darby smelts iron with coke

At Coalbrookdale in Shropshire, Abraham Darby figured out in 1709 how to use coke — coal baked at high temperature to drive off impurities — to smelt iron in a blast furnace. Charcoal had been the only viable fuel for iron-making for over two thousand years. Coke was abundant; charcoal required ever-shrinking forests. Darby's process let iron production scale with coal mining rather than with woodland regrowth. Within a century, British iron output had risen by a factor of forty, and every machine of the Industrial Revolution — steam engines, rails, ship hulls, factory frames — was built from coke-smelted iron. It is the moment fossil fuels enter heavy industry.

1712

Newcomen builds the atmospheric steam engine

Thomas Newcomen installed his first commercial steam engine in 1712 at a coal mine in Dudley, England. The engine pumped water out of the mine — a problem that had become acute as miners dug deeper to find more coal. The Newcomen engine was inefficient by later standards (about 1 percent thermal efficiency), but it solved the bottleneck that had been limiting coal output for a century. By 1733, more than 100 Newcomen engines were operating across British coal fields. Coal was now powering its own extraction, in a feedback loop that would scale for the next two centuries.
