A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. For example, if you clean your floors with a 1,watt vacuum cleaner for one hour, you consume 1 kWh of energy. Your kilowatt-hour consumption factors in how many watts your appliances use and how often you use them.
The difference between kWh and kW , and what you see on your bill, is that kW reflects the rate of electricity you use, and kWh indicates the amount of electricity you use. The power you use on a daily basis can quickly add up to 1 kWh if you are frequently using high-wattage appliances in your home.
Keep this in mind, as energy companies typically charge for power on a per-kWh basis. Knowing the difference between kW and kWh can give you powerful insights to help monitor and manage your electricity consumption.
Make a list of appliances that you frequently use and do the same calculations. You can then start to balance your usage by examining which appliances require the most power kW and energy kWh. Utility companies measure your kWh with digital meters right outside of your home where the power line goes into the property.
Now that you have mastered what is a kWh of electricity and how power is measured in a month, you can start making some adjustments to save on energy consumption in your home.
Utility companies measure your kWh with mechanical or digital meters right outside your home. Newer digital meters use high-frequency signals to send data to the utility companies about your electricity usage.
Not surprisingly, heating your Alberta home takes up a whopping 61 percent of your estimated energy usage, according to Natural Resources Canada. However, learning what a kWh is and how you can reduce your annual costs in other areas can help balance the added expense of heating your home throughout the year. Perform a thorough review of your electric bill to assess your monthly electricity usage and costs.
Now that you know what a kilowatt-hour is, you can dig a little deeper to see which appliances are using the most electricity. Think about installing a home energy monitor , which will provide you with detailed tracking of your household electricity consumption.
Certain home energy monitors are wireless and can even track energy usage by appliance. Another example is ten watt light bulbs used for 1 hour. Identifying which appliances use the most electricity in your home means that you can control the amount you spend on electricity.
As a guide, the diagram below shows how long you can use various appliances for the price of one unit of electricity. These figures give an average usage guide. Actual usage will depend on the age and efficiency of appliances. Have a look at our latest price plans to find out the price per unit of electricity.
