Technology and bills, so you can count how much you’re spending: Here’s how to save –

Are you trying to reduce your consumption but the bill cost remains constant at the end of the month? Find out how to calculate the real consumption of your devices thanks to this formula.

In this period, with the increase in energy prices, Italians are increasingly interested in their consumption. Many try not to overuse household appliances in order to save money. But do we actually know how much our devices are consuming when we use them?

If you want to save and reduce your electric bill, it is recommended that you know how much electricity your home consumes and how many kilowatt-hours a refrigerator, washing machine or water heater consumes, to understand whether it is necessary to change appliances. Or simply your consumption habits.

It is useful to know the estimate of your electricity consumption to better understand how much you spend on the electricity bill, whether there are errors in the event of a suspicious bill and in the case of possible savings.

How do you calculate your consumption?

Depreciation varies mainly based on a few items: The number of people Living in the house The number and type of household appliances Present.

Consumption also changes according to the habits of the inhabitants, if we spend too much time at home we will consume more than one who works and is always away from home.

The type of appliances is important because, for example, the consumption of a new generation A + energy class refrigerator can be much lower than a 10-year-old refrigerator. Air conditioner and electric water heater are two devices that consume a lot in general and therefore can be an item that makes a difference in a household account.

Each device has a nameplate indicating the power that can be expressed in W or kW, which corresponds to thousands of W (1000 W). This is a measure of energy not to be confused with kilowatt-hour (kWh), which is the unit of measurement for energy consumed.

to reach consumption From which device you should Multiply the power by the hours it was run. For example, let’s say a 70W fan has been running for 8 hours at full speed. To find out how much electricity you will consume, the calculation is simple:

• 70 watts x 8 hours = 560 watts (0.56 kWh)

But the problem is that The device does not always run at full power, which is indicated on the label. During operation, the instantaneous power absorbed by the fan varies according to the set speed.

The washing machine and dishwasher absorb high energy at the beginning of the wash cycle, especially for heating the water, while the maximum speed requires less energy. On the other hand, the refrigerator motor does not run continuously, rather it turns on and off based on a sensor that measures the internal temperature.

If we want to measure the consumption of a single appliance accurately, there are devices available in the market which must be inserted between the appliance socket and the socket in the wall. these Electricity meters determine the flow of current Hence the electricity consumption. The latest models also have a practical display that indicates power and consumption, and they are available on the market at affordable prices (10-20 euros).

family consumption

there Expenditure on electricity for a family It depends primarily on its consumption. For the above reasons, an accurate calculation of the kilowatt-hours actually consumed is difficult and can only be achieved using a special meter.

The electronic meter measures kilowatt-hours from the house since its installation, remember that if you want to know the consumption, you need to calculate the difference between two readings in a certain period of time.

With the increase in the number of family members, Consumption is growing but not proportionately Because of the so-called economies of scale.

A family consisting of two components:

• the television
• Washing machine and dishwasher
• refrigerator
• the computer
• freezer
• Consumption 1660 kWh/year
• Electricity bill €275/year
• Average cost 0.165€/kWh

A family of 3/4 members:

• 2 TV
• Washing machine and dishwasher
• refrigerator
• 2 computers
• freezer
• 2 air conditioners
• Consumption 3300 kWh/year
• Electricity bill 695 euros / year
• Average cost 0.21€/kWh

Family of 6:

• 3 TVs
• Washing machine and dishwasher
• refrigerator
• 3 computers
• freezer
• 3 conditioners
• dryer
• Consumption 4,800 kWh/year
• The cost of the electricity bill is 1415 euros per year

Average cost 0.295 euros / kWh
