How to Find What Is Driving Your Electricity Bill
Electricity use is measured in units (kWh). You can estimate any appliance with a simple formula: watts × hours used ÷ 1,000 = units.
Worked example
A 100-watt device that runs for 10 hours uses 1 unit (100 × 10 ÷ 1,000). A device that draws ten times as much power uses ten times as many units in the same time. Check the watt rating on the appliance label, then multiply by your daily hours and by 30 for a monthly figure. Your bill shows the rate per unit that your supplier charges.
Steps
- List your main appliances and their watt ratings.
- Estimate the hours each runs per day.
- Rank them by estimated monthly units. Air conditioners, water heaters and old refrigerators usually top the list.
- Cut hours on the top items first, then replace the oldest ones with efficient models. Look at the star label of the Bureau of Energy Efficiency when you buy.
- Compare your monthly bill before and after.
Common mistakes
- Leaving devices on standby all day.
- Never cleaning AC filters, which makes the unit work harder.
- Buying a cheap appliance with a poor energy rating that costs more to run over time.
