The United Kingdom discovers the Jevons paradox.
As energy efficiency increased throughout the 20th century, so did energy consumption.
@blair_fix Also, it can be explained by market efficiencies resulting from higher sales volume, no? Assuming your claim is that efficiency results in more use. I imagine a similar graph can be made for car sales vs fuel efficiency.
@blair_fix I just don't see efficiency as a one way cause of increased consumption, I think they boost each other.

Yes, having more machines is part of the efficiency backfire.
