So that encouraged the British to look for more coal. The only problem with coal mining, aside from it being, you know, like, deadly and everything, is that the coal mines flooded all the time. I guess coal mining is also a little problematic for, like, the health of, you know, the, like, the planet. But because there was all this incentive to get more coal out of the ground, steam engines were invented to pump water out of the mines. And because those early steam engines were super inefficient, they needed a cheap and abundant source of fuel in order to work, namely coal, which meant they were much more useful to the British than anyone else. So steam engines used cheap British coal to keep British coal cheap, and cheap British coal created the opportunity for everything from railroads to steel, which, like so much else in the Industrial Revolution, created a positive feedback loop. Because they run on rails, railroads need steel, and because it is rather heavy, steel needs railroads.
