Appliance energy use

How to use it

1. 1Enter the electricity price from your bill (€/kWh including taxes).
2. 2Add each appliance with its power in watts (on its label), the hours a day it runs and the days a year.

How it calculates

• kWh per year = watts × hours per day × days per year / 1,000.
• Cost = kWh × price per kWh.

Verifiable example

With electricity at €0.18/kWh, a 150 W fridge 8 h a day, a 1,000 W washing machine 1 h on 150 days, a 2,000 W oven half an hour on 100 days and a 100 W TV 3 h a day add up to 797.5 kWh and €143.55 a year.

Limitations

• Appliances that switch on and off by themselves (fridge, air conditioning) use less than their maximum power all the time: use their real running hours or the annual consumption on the energy label.
• It doesn't include the capacity charge on the bill.
