Washing machines, showers, and tumble dryers account for a significant portion of the average energy bill, putting them at the top of our energy guzzling list. Anything that requires heating water up will use a lot of energy.

Choosing to wash your clothing at a lower temperature can help you conserve electricity. Use the Eco option if the appliance has one and try to start it only when it’s full.

Fridges and freezers are responsible for a large percentage of the average household’s energy cost. Because these appliances must be on at all times, they are constantly consuming electricity to maintain a steady temperature.

Because they will be on 24 hours a day, investing in an energy efficient one is a major advantage. When shopping for a new refrigerator or freezer, consider both the smallest model that matches your needs and the highest-rated one that you can afford.

What you use to cook can also affect your energy bills Kitchen appliances such as the oven, electric grill and the microwave consume about 4% of your energy bill. Microwaves are more efficient and cook faster than ovens because they only heat the food and not the air around it.

Electronic equipment like an LCD TV, games console and a computer consume energy even when they are turned off. If you keep your laptop plugged in after you’ve stopped using it, it will continue to drain energy.

Similarly, even in standby mode, your television and game console will consume energy.

consumer electronics

Other equipment, such as your internet router and modem, will also consume energy. As a result, unplugging your equipment while not in use can help you save money on your power bill.

Which appliances use the most electricity when turned off?

The top appliances that use electricity even when turned off are TVs, computers and phones because they don’t usually have the plugs taken out.  Most electrical and electronic appliances can safely be turned off at the plug without damaging their systems. 

Check the instructions on the appliance if you are not sure it can be turned off at the switch.

Ways to monitor and lower your electricity usage

There are a few ways to monitor your household electricity consumption:

Meter energy monitor

Domestic Energy Smart Meter Displaying Energy Usage in Real Time

If you have a smart meter installed, you will have been given an energy monitor that can be left on to give you consumption and cost date for the day, month, week or year.

Meter reading

If you don’t have an energy monitor, you can take a meter reading at regular intervals to give you a picture of how much you use.

Energy consumption analyzer app

This simple app by Cristoph Zens, available on Play Store,  helps you keep track of consumption by entering meter readings and usage over time is shown as graphs. Type the words as in the headline here and look for this logo.

Alexa energy monitoring for enabled devices

More home appliances are becoming interconnected now and Alexa has an energy monitoring function to show your energy usage for items connected to the hub.   

Plug power meters

These monitor electricity consumption of an appliance you plug into it.  The unit plugs into the wall socket and the appliance plug goes into this.

This is the traditional way to view consumption, usually over 3 months.
