The Jevons paradox

What is the Jevons paradox you ask? Well, its the observation that (I guess) someone called Jevon's made, that increasingly efficient technology does not lead to more the use of fewer resources. Quite the opposite in fact!

In fact, as efficiency increases, resource use also increases. For example according to this video, increasingly efficient cars means that the money people save by using more efficient cars then is sloshing around looking for something to do and gets spent (in this example) on more trips. This of course leads to an increased consumption of oil. We've seen the same effect with heat pumps in New Zealand. Installing heat pumps has led to an increase in electricity consumption because people can heat their homes better for less cost. The video points out that the only way to counter this is to increase leisure rather than increasing productivity. Looked at this way, going part time or taking more holidays is doing the planet a favour because we need to produce and consume less stuff if we are going to become sustainable. Any other ploys simply increase consumption, which is not the point.

So slow down, work less, enjoy more of the flowers, become more physically active and spend more time with those important others in your lives. Working long and hard is not sustainable and as others have pointed out, not many people regret that they haven't spent more time at work when they are on their deathbed!
