Finding the electricity hogs in your home
Your electricity bill shows your total consumption, but not which appliance is responsible for it. Once you identify the biggest consumers, you can make changes that really matter. This guide shows how to investigate systematically.
You will need
- Access to your electricity retailer’s or grid company’s consumption service
- A plug-in energy meter
- Notes or a spreadsheet
- Appliance rating plate details
Steps
Check your hourly consumption
Log in to your electricity or grid company’s service or Fingrid’s Oma Datahub service. Look at your consumption hour by hour: the base load at night shows what is used when nobody is using anything.
