One important part of saving electricity is keeping an eye on your usage. One good idea is to get a smart monitor or similar device to keep a close eye on how much electricity you are using. Make it a regular practice to monitor it so you can work out how much electricity is being used. You can then examine by timeframe if there is a particular time or situation where more electricity is being used and work out how to adjust your usage accordingly.
You can also keep a manual record. Although it will be more difficult to identify appliances that consume more it will help prevent bill shock by knowing how many kw’s you have used.
