Wind energy’s high level irony in Knight’s airborne turbines cartoon
Wind is on the up as a renewable energy source but the wild weather across multiple states exposed a possible design flaw that had cartoonist Mark Knight imagining turbines taking off for real
READING LEVEL: GREEN
This week the eastern and southeastern states copped an absolute earful of wild, windy weather, hail and rain. I guess we should be used to weather with “attitude” these days. Apparently it’s all due to this thing called climate change* and many scientists predict that these severe weather events will become the norm.
In Victoria and Tasmania, gale force winds* lashed those two states for nearly a week, with trees down, roads blocked, homes damaged, power supplies cut off, internet and phone networks down and people told to stay home.
Generators* became the new status symbols* for neighbourhoods. Forget the BMW parked in the driveway; if you had a diesel generator revving away in the frontyard lighting up the house and keeping the fridge running, you were someone to be both admired and envied.
Anyway it can’t be all bad, I thought. It’s good weather for the wind energy business, the turbines* must be going flat stick pumping out tonnes of kilowatts of electricity with this constant supply of a brisk breeze.
It was then that I found out these gusts were at times too strong for wind turbines and that they were locked down in such extreme weather situations to prevent the rotating turbines from being damaged.
Sometimes cartoon ideas just flash inside my head when I read or hear something and this was one of those occasions.
I imagined a vista of rolling green hills in rural Victoria, planted-out with those majestic* white rotating wind turbines, harnessing the breeze from the southern ocean provided for us by Mother Nature and generating clean, renewable* electricity.
But Mother Nature can be a testy* type at times and this week the winds were so powerful, over 120 km/h, that I imagined not only trees and kids’ trampolines taking off, but our huge wind turbines being torn from their foundations. The cartoon shows the uprooted windmills soaring skyward, self-relocating, due to the cyclonic* conditions.
This is of course me being the typical cartoonist and using my cartoonist’s licence to exaggerate to make a point, but when the wind exceeds a designated* speed, the turbines stop spinning. Fair enough. They probably would take off if those blades were spinning freely in a 120 km/h breeze!

GLOSSARY
- climate change: long-term shifts in global temperatures and weather patterns
- gale force winds: strong winds of force between seven to 10 on the Beaufort scale – an empirical measure that relates wind speed to observed conditions at sea or on land – or from 45 to 90 km/h
- generators: machine that produces electrical power
- status symbols: something that a person has or owns that shows they have something of value or importance to others
- wind turbines: machines that converts kinetic energy from the wind into electricity
- majestic: impressive, magnificent, very beautiful or striking
- renewable: energy produced using natural resources that are constantly replaced and never run out
- testy: bad tempered, irritable, grumpy, easily provoked
- cyclonic: relating to a cyclone, refers to very wild or cyclone-like conditions
