It is a timely reminder to look around your home and check every device that is plugged in. Once checked, make sure to unplug any unwanted or unused electrical devices, as they could be adding to your energy bill.

While turning off energy-sapping devices every night may seem too time-consuming for some, the savings can be significant and there are ways to make the task a little less onerous. You could consider plugging multiple devices into one extension lead, meaning there is only one switch to turn off at night or alternatively you could invest in some smart plugs which will automate the process for you.
