As with the , contemporary New English observers noted the local climate changes in New England by the late 1700s, when the summers got hotter, the winters colder, and the land became more arid. Streams disappeared during the summer and flooded in the winter. In his classic study, William Cronon noted that New England became “sunnier, windier, hotter, colder, and drier” than before it was deforested. The eastern seaboard began turning to British coal soon after the American Revolution. , and early America relied on British coal. It was not until canals and railroads were built that the USA began to use its domestically mined coal. The anthracite mines of Pennsylvania turned Pittsburgh, Buffalo, Philadelphia, and other cities in the region into the heart of early American industry. Steam locomotives were , and is credited with building the first , after many years of effort. The opened for business in 1825, and the was built between Baltimore and the Ohio River in 1830, as Baltimore competed with the canals that serviced Philadelphia and New York. Railroads became humanity’s first low-energy transportation lanes that were not bodies of water (roads kind of qualified, but they were minor advances compared to railroads). Many American cites were not built on bodies of water but along rail lines and, later, roads traveled by cars and trucks.

England had nearly a century’s head start on the competition with its Industrial Revolution, which is why it became the world’s triumphant imperial power, to be later supplanted by its offspring and rival, the USA. Turning coal into an industrial fuel, for smelting iron and powering machines, initiated the Industrial Revolution, and the next big innovation was making machines to replace hands. English inventors , and the 1760s and 1770s were the golden age of spinning innovation, and the , , and were all invented. By the 1790s, people using such machines . I call one worker with a machine outperforming 150 people without one an energy-and-technology-leveraged human. Energy-powered technology allowed a person to vastly outperform humans without it. Was that person 150 times more dexterous? Smarter? Faster? Stronger? The machine did the work, not the person, and energy made it all happen, not the equipment. Without energy to run it, machinery is useless, but without human-made technology, the energy was unavailable. Such machines would never have been without the available energy to run them. Those early spinning machines ran on water power from the .
