Reducing our electricity costs


LatestChanging to a new electricity provider (2023) >>>


The Journey Begins

In 2007 we were belting through over 5000 kWh of electricity each three month billing period. As the cost of electricity increased, the cost of maintaining this level of consumption was unsustainable for our family.

At the time, we were using:

    • 5750 kwh of electricity per quarter;
    • at the rate of 63 kwh per day.

For the use of this electricity we paid:

    • $695.00 for the three month Spring period (Sept / Oct / Nov);
    • at the rate of 12c per kwh;
    • or $7.60 per day.

Then the cost of electricity began to skyrocket – if we continued to consume energy at this rate we would soon be paying over $1000 per quarter for our electricity.

In fact 12c/kWh quickly became 25c/kWh, and in 2023 rose to 34c/kWh. If we were still using 5750 kWh of grid electricity in 2023 we would be paying $1955 per quarter ($650/month) or $7820 a year..


Consumption Down, Costs Up

In an effort to balance our household energy budget we began reducing our energy consumption – we all took shorter showers (well, most of us), reduced washing machine cycles, returned unused parts of our home to darkness in the evenings, and wore more warm clothes on cold days rather than using heating.

While this certainly reduced our electricity consumption, it didn’t save us any money – the electricity supplier simply increased the unit cost.

So we had to take more drastic action to reduce our dependence on grid electricity, and the associated costs.

This site provides a diary summary of our efforts to address this issue over the past few years….


Finite reserves  

The Big Picture – Finite Reserves

At the rate we are burning through fossil fuels, one day it will all be gone. The lot. No more left to dig up.

2023Changing our Grid Supplier

The addition of an EV to our list of appliances powered by electricity has seen us change to a new energy supplier – one with an off-peak EV charging plan. And there are considerable savings.


EV charging  

2023 – Moving to an EV

Well, this isn’t going to save on the cost of electricity, but it is going to save a motza on the alternative fossil fuel energy being consumed for our daily transport. And we might even help save the environment!


Dollars vs kWh chart  

2023 – Suppliers scoop the $

We are all using less electricity – which can only mean one thing – the electricity companies will increase their rates to keep their bottom line looking healthy for shareholders and investors. The less you use, the more you pay!


Battery and solar  

2022 – Is a battery an option?

If you have enough ‘spare’ solar output, you can install a battery to store excess solar-generated electricity for use when the sun isn’t shining. 


Gas hot water  

2021 – Gas Hot Water

Our storage hot water was costing a bomb, even when we weren’t using it! And when we were using it we were running out of hot water. So we switched to instantaneous gas heating for our hot water.


Electricity dollars  

2017 – Suppliers strike back

Always looking after their bottom line, the electricity suppliers bumped up the cost of energy to compensate for our further-reduced consumption. Again.


Solar panels  

2015 – Going Solar

We reduced consumption, so suppliers increased the cost of the energy we were using. Our next step was to install solar panels to generate our own electricity and reduce our dependence on electricity from the grid.


Reducing consumption  

2007 – 2009: Reducing Consumption

Our first step to save money on energy costs was to use less energy – but the energy retailers were on to this!
