We recently had the climate smart electrician here and the fifty dollars was well spent as you get the device to measure the amount used and the same monitor allows you to see what takes how much to run.You also get 4 remote power points (which also give surge protection).
the power hungry devices are the heaters (water, clothes ,space ,oven etc).
you will save heaps if you monitor and adjust your usage ,like only boiling the appropriate amount of water in the kettle,washing clothes in cold water,filling the oven instead of just one tray of biscuits, jumpers over heaters etc.The sparky told a story of one house in Noosa that had a wall of glass door fridges to house a six pack of beer and his power bill was three grand per quarter. I have a chest freezer with an added thermostat/control that holds two 19 lt kegs that only takes .4kw to run most of the savings comes from the fact that the door is on top so the cold doesn't pour out every time I get a beer.
the end of suffering comes from the living of joy!
