It’s relatively easy to work out the cost of using home appliances:
- Electricity is measured in Kilowatt hours (KWH).
- A KWH is the amount of electricity consumed in 1 hour by a 1-Kilowatt appliance.
- The average cost of 1 KWH is about 14p, but this will depend upon your supplier.
Take the power of the device (in Kilowatts), and multiply by the cost of 1 KWH, to calculate the rough cost per hour of the device.
Example 1
A Tumble Dryer will run at between 3 – 5 Kilowatts, so the running cost would be between 40p – 70p per hour.
Example 2
A 40 Watt Light Bulb running at only 0.4 of a Kilowatt would cost about 0.5p per hour.
