With better living standards and the addition of modern comforts, we have come a long way in making our lives easier. However, the prospect of living without our gadgets and appliances may seem like a nightmare to most people.

Lighting, heating, cooling, networking, and communication devices, and many such appliances require electric power to operate. Some of these may use more electricity compared to others.

The result reflected in your electricity bill may make you wonder which appliances use the maximum power in your home. As a result, you may wish to limit the use of these appliances to reduce the cost of electricity.

In this article, we will tell you about those appliances and devices that consume the most electricity in your home. So, come on, let’s get started!

How To Calculate Which Appliances Use The Most Electricity?

We use several devices in our daily lives that require electricity, some of which may consume more power than others. You can use several methods to determine the power consumption of your appliances. We have mentioned some of the ways below.

  • Use the power usage monitor to determine a device’s electricity consumption.
  • You can install a house energy monitoring system that will tell you how much electricity every appliance in your house uses. A professional electrician like Air Pro Heating, Air & Electric can help you install such a system.
  • You can also check the Energy Guide label on specific electronic devices that provides that appliance’s estimated power consumption.
  • By knowing the power wattage of your electronic devices, you can calculate their energy consumption using a simple formula. However, you need to know the estimated time for which you use the device before calculating the energy consumption. The formula is as follows:

  For daily energy consumption,

(The wattage of device x No. of hours used in a day) ÷ 1000

You will get the daily kilowatt-hour (kWh) energy consumption.

  For annual energy consumption,

Daily kWh consumption x number of days you used the device in a year

This will give you the annual energy consumption. Multiplying these values by the utility rate per kWh will give you the cost of usage of these appliances.

How To Tell Which Appliances Use The Most Electricity?

Using the formula discussed above, you can calculate the power consumption of every home electronic device.

The formula requires only two basic things: the wattage of the device and the number of hours you use it. You don’t have to calculate the energy consumption to know which electronic devices use the most electricity.

Most electronic devices have the wattage mentioned under their specification label. If the wattage mentioned on the label is high, it means the devices will consume more electricity to run efficiently.

Some devices also come with energy stars that help you figure out the energy consumption of different models of the same device.

Here are some of the devices that use the most electricity in your home.

Heating Devices

Appliances that provide heat use a lot of energy to function properly. Some of these heating devices include microwave ovens, home heating systems, electric irons, water heaters, hair dryers, induction cookers, and others.

In addition, some devices produce heat as a result of their constant use, which may lead to the wastage of electricity.

Air Conditioners And Refrigerators

Cooling systems and devices like air conditioners and refrigerators consume a large part of the total electricity in your home. They take up more than 30% of your electricity and lead to high electricity bills. In addition, they use the most power during the summer months.

Washer And Dryer

Using washers and dryers daily can lead to increased power consumption and electricity bills. Choosing energy-efficient devices can reduce the energy consumption of these appliances.

Depending on the type of lighting devices you use for your home, the energy consumption may vary widely. For example, incandescent light bulbs use the most electricity, while LEDs use the least. In fact, LEDs use 90% less energy compared to incandescent lamps.

Entertainment and Media Appliances

Devices like televisions, computers, video game consoles, set-top boxes, and home audio systems can take up a significant part of your home’s electricity. Since these devices are used for long hours and take up standby power, you will have to pay more for your utility bills.

How To Reduce Electricity Consumption In Your Home?

By limiting the usage of high energy consumption devices and systems, you can significantly reduce your electricity bills. Follow these simple tricks to reduce power consumption and save electricity and money.

  • Turn off lights when they are not in use. Switching to energy-efficient bulbs like LEDs can also help save electricity. You can rely on natural light during the day and not waste electricity unnecessarily by using electric lights.
  • Reduce your shower time. Takingshorter showers can help you save water, electricity, and money. It is also beneficial for your health, as long showers lead to skin and hair dryness.
  • Turn off and unplug devices when not needed. Keeping devices plugged in when they are not in use can take up standby electricity. You can save a lot if you choose to unplug devices.
  • Use air conditioning to lock windows and doors. Keeping windows and doors open can let in heat, and your air conditioner will have to work harder to cool your home and use up more energy. Hence, you should seal and lock your home to prevent heat from escaping inside.
  • Wash full loads and use cold water in your washers. Do not overfill the machine; use dry racks as much as possible. You should also clean the lint after every load.

Wrapping Up

Knowing how to calculate the power consumption of appliances in your home can help you save money on your electricity bill by reducing their use.

If you know the wattage of your device, you can tell how much electricity your appliances use. If the wattage is higher, the device uses more electricity. Following some simple tricks can help you reduce power consumption significantly.
