The basic unit of electricity is the Kilowatt hour (kWh). In simple terms, 1 kWh is the amount of energy used by a 1kW (1000 watt) electric heater for 1 hour.
Check the rating of your appliance.
Brand new appliances aren’t cheap. But over time, the money you could save on your energy bills will offset the initial expense.
The important thing is to make sure you figure out what the biggest energy wasters are in your home. You can adjust your energy usage by unplugging or just using the device less often. The total electrical energy transmitted to an appliance is determined by its power and the extent of time it is turned on.
Electricity meters calculate the amount of units of electricity used in a home or other building. The more units used, the higher the cost of electricity.
The figures below are a general guide – ideally we’d recommend entering your actual annual usage in kilowatt hours.
