Lets all admit it….Kilowatts are not the easiest thing to understand. Changeworker Daniel “Gannet” Johns (see previous posts) certainly needed some guidance. My task was to devise a simple way to help. Here is how the process went:

Stage One: It was necessary to find out what "The Gannet" did understand…being Australian his reply came as no surprise... “Sport and barbeques mate”

Stage Two: The only heating related aspect of his reply was the Barbie, so I asked what his favourite food was and the size of Barbie... “Prawns and 14.6kW whatever the heck that means”

Stage Three: The calculations commenced and the results were announced - one kilowatt hour will cook 450 King Prawns. The Gannet was delighted, but what does it mean? A typical household that uses around 22000kWh per year could have cooked 1 Million Prawns...

Here is a handy cut out and keep guide:

So my message to all down-underers is to remember every time you leave your computer or television unattended for an hour you could have cooked 45 prawns!!!!
