Until about 1910, plenty of entrepreneurs looked at the new electrical drive system and opted for good old-fashioned steam. Why? Because to take advantage of electricity, factory owners had to think in a very different way. They could, of course, use an electric motor in the same way as they used steam engines. It would slot right into their old systems.īut electric motors could do much more. Electricity allowed power to be delivered exactly where and when it was needed. Small steam engines were hopelessly inefficient but small electric motors worked just fine. It’s interesting to consider the before and after of the steam engine versus electricty: So a factory could contain several smaller motors, each driving a small drive shaft. Old factories were dark and dense, packed around the shafts. New factories could spread out, with wings and windows allowing natural light and air. In the old factories, the steam engine set the pace. In the new factories, workers could do so.įactories could be cleaner and safer – and more efficient, because machines needed to run only when they were being used.īut you couldn’t get these results simply by ripping out the steam engine and replacing it with an electric motor. You needed to change everything: the architecture and the production process.Īnd because workers had more autonomy and flexibility, you even had to change the way they were recruited, trained and paid.įactory owners hesitated, for understandable reasons. Of course they didn’t want to scrap their existing capital. But maybe, too, they simply struggled to think through the implications of a world where everything needed to adapt to the new technology.
