- These are examples. The energy for each use is our own round figure for a typical modern appliance, and how often it's used is a guess for an average home. Yours will differ, so use the watts on your appliance's label for your own sum.
- A cost is the energy in kWh times the unit rate. Watts divided by 1,000, times the hours it's on, gives kWh. The standing charge is left out, because you pay it whatever you run.
- Many appliances only draw their full power part of the time. A fridge freezer, oven or heater switches its element off when it reaches its set temperature, so the label's watts overstate a day's use. A plug-in energy monitor shows the real figure.
