How can you calculate the electricity a house consumes?
Electricity consumption is the volume of energy you use over a given period of time. It is usually measured in kWh, so this is the unit of measurement retailers use when invoicing.
To calculate electricity consumption you need to know the power for each of the appliances you use and the time they are used. The total for all these consumptions within the billing period is equivalent to the consumption for which your bill is calculated.
That is why you need to know the power for your appliances and lighting and take into account for how much time you use them. It is also advisable to be aware of your actual consumption at the moment. All this, together with being fully aware of your habits and being able to adjust them is the key to improving your energy efficiency, and to choosing the Endesa plan that best suits your routine to help you save on your bill.
With smart meters you can now immediately know how much you are consuming. There are also other advantages like:
- Actual reading of consumption on the bill.
- Possibility to consult consumption anywhere and at any time using a device.
- Reliable measurement.
Calculate the kW/h consumed by domestic appliances
We have spoken about how useful it is to know how much your appliances consume. With this in mind, we have prepared a list of the most common appliances and lighting, together with a range of power most common in these devices:
- Television: 100-400 W, which is equivalent to 0.1-0.4 kW.
- Air conditioning: 900-2,000 W, which is equivalent to 0.9-2 kW.
- Microwave: 900-1,500 W, which is equivalent to 0.9-1.5 kW.
- Fridge: 200-400 W, which is equivalent to 0.2-0.4 kW.
- Oven: 1,200-3,000 W, which is equivalent to 1.2-3 kW.
- Incandescent lamp: 30-80 W, which is equivalent to 0.03-0.08 kW.
- LED light bulb: 3-12 W, which is equivalent to 0.003-0.012 kW.
To calculate consumption, you multiply the power in kW by the hours you use the devices per day, per week or per month.
For example, let's examine the consumption at the home of Agnes and Roman:
The TV has a power of 200 W, that is, 0.2 kW. They have it on for 2 hours a day, so their daily consumption is 0.4kWh. If you want to know your monthly consumption, you just multiply the daily consumption by the number of days in the month, for example, 30. So you would have a monthly consumption of 12 kWh.
If you make the same calculation for the consumption of all the appliances in the house of Agnes and Roman, you would know their exact consumption.
This information is very useful not only to be able to control the use of appliances and use them efficiently, but it will also help you choose the most suitable appliances. You should remember that all appliances should be accompanied by the corresponding information on efficiency, as well as the technical specifications which should include the power.
