Killing Vampires

I want to suck your power.

When I hear of vampire power, it doesn’t conjure up images of my appliances sucking the life blood out of our planet. Alas, that’s pretty much exactly what it means. Also known as standby power, this is the power used by your electrical devices when they are in standby mode. This wasted electricity doesn’t come cheap, costing Australians “a combined $860 million annually” and “almost 2.6 million tonnes of carbon dioxide emissions per year”.

Now, stabbing your appliances through the heart with a wooden stake might be fun, but it’s a challenge that could see you electrocuted if you aren’t careful. Happily, there is an easier way to tame these vampires so that you’re only using electricity when you’re, well, actually using electricity.

Introducing: the off switch at the wall.Power switch

This little switch is a nifty device that stops your devices from drawing electricity, and it was an astonishing discovery – for some people in this house – that once they are turned on you can actually turn them off again. It requires the Herculean effort of reaching over and flicking the switch so that the little red line isn’t showing. We’re lucky to have these switches in Australia, because poor unfortunates in other countries have to go to the trouble of actually pulling the plug out of the socket.

Once I discovered how much vampire power was costing us, I was on a mission to turn off everything at the wall. Microwave, computers, stereo, it was all powering down. The data from our smart meter shows that this has reduced our base hourly electricity consumption from 0.1kWh to 0.04kWh per hour. That might sound trivial, but over the course of a year this is a change of 525.6kWh or 0.48 tonnes of carbon emissions. Did I really need to have my exercise bike drawing power all the time? Since I didn’t even know it was plugged in until I checked the points, I suspect that I didn’t.

Turning things off at the wall has led to some unexpected changes. Our reliance on electronic devices for entertainment has dramatically reduced. The children are stuck playing with each other instead of watching the television because I’m too lazy to turn it on for them, and their relationship has dramatically improved. I tend to look things up on my mobile instead of powering up my energy guzzling PC. Even my partner has discovered that he doesn’t need perfect WiFi signal when it requires walking all the way into the next room and turning on our signal booster.

If you’re playing along at home…

… what can you turn off at the wall or unplug that doesn’t need to be running all of the time? Please share your suggestions in the comments below.
