Electricity Costs: DIY energy audit on your home

Electricity costs are on the rise.

Electricity costs are rising and with more people switching to solar and becoming less reliant on grid power it is likely they will continue to rise.

Household power consumption has also dramatically increased over the last few decades. Society has become more reliant on electrical products such as computers, televisions, dishwashers etc than ever before.

But how can you work out how much these appliances are costing you to run and how can you use this information to save money?

Conducting your own energy audit

Working out the energy use and electricity costs of an appliance is very simple and you can conduct your an energy audit yourself. All you need is a few pieces of paper, a calculator and a few spare hours. You will also need a recent copy of your electrical bill to identify the cost of your electricity per unit.

Start by doing a “stocktake” of all the electrical appliances in your house. Estimate the usage time for each appliance. For instance, kettles are generally used a few times per day for short periods. Televisions, however, are often for many hours during the day. Don’t forget to include things such as your lights, electric hot water system, fridge, oven etc.

Next, you need to determine the appliances rate of energy consumption. For example, a 1000w appliance will use 1000w for each hour of use.  Most appliances will have a sticker indicating the wattage of the device.

Once you have the wattage, you will need to convert it to kWh. To do this, simply divide the number of watts by 1000. For example, a 60w globe converts to 0.06 kWh.

Finally, multiply the kWh by the number of hours of use each day and multiply this by the cost per kWh as show on your electricity bill. Voila! You now know how much each particular appliance is costing you to run per day. You can then multiply that out to determine the weekly, monthly and annual costs too.

If you are finding your electricity costs are unusually high, try conducting your own energy audit. Otherwise, contact us and we can help you determine the cause.
