Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“. Definitely worth a read…
Last week, The Age published a piece by its Economics Editor, Peter Martin, called Power down: What the Melbourne Cup can teach us about fighting climate change. It began with a pretty interesting observation about changes in electricity usage that happen as people down tools or computers or something and watch the Melbourne Cup. It wasn’t that long ago that I took the constancy of the electrical output at wall sockets for granted. Martin echos my own fascination at finding out a little of the black art, otherwise known as power engineering, that makes it happen. It’s not magic, people have to do stuff … sometimes on a minute by minute basis.
Martin turns this into an energy efficiency rant by somehow imagining that we consumers can, by collective action, conquer climate change in the same way that US consumers crushed the oil crisis in the 1970s by switching to 4-cylinder cars and insulating their houses. What? Is that what really happened or did Martin just make it up or repeat something he heard in the pub from somebody who heard it from a mate who knows Amory Lovins?
Let’s check. We can go to the International Energy Agency website and with a little hunting find a chart of US Oil use since 1972. Here it is.
Just looking at it is instructive. The standout decline is down the bottom. Fuel oil. None of the others look to contribute much on their own. Fuel oil’s use peaked around 1978 and then crashed. Print the image and measure. It’s down by almost 11 millimeters over the following decade on my printout … close on 100 million tonnes.
