Steam-powered factories: Reconfiguring to adopt new technology
History is full of examples of innovation and new standards combining to solve problems. One notable example is the electrification of factories in the early 20th century. In the years before electric motors, the predominant way to power a factory was through coal-fired steam. In a steam-powered factory, a single, gigantic steam engine would power a huge, rotating drive shaft. The drive shaft would run the length of the factory, and all the machines were hooked up to it.1, 2
The steam-powered factory was a marvel of its time, but it had its drawbacks. The factory could run no faster than the drive shaft could spin, so no single worker could work ahead of the steam engine’s pace. To power even a single machine along the drive shaft, the entire steam engine had to be powered and running.
When electric motors came around, the technology came with the promise of greater productivity and efficiency at a lower cost. But there was a hitch: Factories had to be completely reconfigured to enjoy the advantages of adopting electricity. The few factory owners who replaced their steam-powered machines early on but retained the legacy configuration, found that their production output barely changed, and their cost savings were nominal.
The real benefit to electric power for factories was that they no longer were dependent on a single steam engine and rotating drive shaft. The entire operating model of factories could be more efficient, with multiple parallel production lines and the ability to run individual machines in isolation. Workers had the autonomy to produce at their own pace, and they could be paid more for greater productivity.
In order to completely realize the benefits of the new technology of the electric motor, however, factories had to reimagine their entire operations. That’s why it wasn’t until the early 20th century that factory owners broadly began to transition to electric motors, even though electric motors first appeared around 30 years prior.
