Kill-a-Watt Energy Meter

Back in 2006 I built up a Dick Smith kitset energy meter. It measures electricity usage for individual appliances.

• some data

In late 2008 I bought a more accurate Kill-aWatt (version 2) meter from Alternative Technology Association for AU$80. The old meter gave readings up to 10% wide of the same appliances with this new meter.

I use this to try to work out what I'm spending my power on - and therefore what options I have for reducing power usage.

Interesting:
