Setting a target for your electricity use (and sticking to it)

Have you heard this old truism?

“If you can’t measure it, you can’t manage it”

It is so, so true. If you only get your meter read every 3 months, how do you keep tab of your electric use on a daily or weekly basis?

And more to the point, how much electricity should you be using anyway?

Well first let’s talk about electricity use targets. A sensible target that is very achievable is 1000 kWh per person per year or 1500kWh per year if you live alone.

That’s 2.7kWh per person per day or 4kwh per day if you live alone.

This is very achievable if you have followed the advice in this series of emails.

The best way to track your energy use on a day-to-day basis is to install a real-time wireless electricity monitor. These consist of a sensor which is clipped onto the wire going into the electricity meter.

This sensor beams the real-time electricity reading to a digital display which you can put anywhere in the house, so you can see how much you are using at any time. Just by being aware of how much juice is being used, you will save 10-20% through changed behaviour.

But even more importantly, you can set yourself a daily electricity target and check that you are hitting it each day.

My favourite device is called a CurrentCost ENVI. I've got one and it even lets me log my energy use on my PC or upload it to a new Google service called Google Power Meter.

And if you get a solar system, it can track your energy generated by your solar panels too.

You can get through the link below for about $150:

Buy one, get it installed, and you’ll soon get a really good feel for where your electricity is going. Combine this with the measures that we’ve covered in the last 7 emails and you’ll soon be a world class energy miser!
