This hairdryer, used at full power, uses 2000 Watts (W) of electricity

1,000 Watts (W)  = 1 kilowatt (kW) ……….  So 2000 Watts (W)  = 2 kilowatts (kW)

We pay for the electricity we use in our homes in kilowatt hours (kWh) – the cost of using 1 kilowatt of electricity for 1 hour

The more kilowatts we use in an hour, the more kiloWatt hours we’ll have to pay for

Using our 2kW hairdryer for 1 hour will use 2 kilowatt hours (kWh) of electricity

Using our 2kW hairdryer for 2 hours will use 4 kilowatt hours (kWh) of electricity
