The units are kWh. DH gets this info through talks and seminars through work. It might only be for the average Perth household

43 units. wow! do use your dryer a lot? that's a very common culprit. Old appliances will also be a drag, and the a/c definitely.

We have solar hot water, gas oven/stove and other stuff is electricity (including evap a/c). We have ducted gas heating, but we didn't use last winter as it crapped out. We just go solar panels put on so looking forward to future bills...

ETA - m yparents have solar hot water, but evap a/c, big plasma tv (bills go up when my brother's around) and other usual stuff and their average is 20-something. They also have pumps for the water (from tanks)
