[Power Saving Tips] 8 Electric Appliances that are Consuming More Energy Than You Think

  • Jan 14, 2022

Household electricity consumption is not low, especially if you have appliances that consume a high amount of energy, even when it is in standby mode. Let us share 8 electrical appliances that consume more energy than you thought!

No. 8: Washing machine

The unexpected power consumption of the washing machine is not its power, nor the power consumption during standby mode, but the different washing modes! The washing machine has different washing modes to cater to clothes with different washing requirements, and the “delicate washing” mode for washing the sweater has the most unexpected power consumption rate.

Because “delicate washing” needs to change the direction of rotation more times than “strong washing”, each time the direction of rotation changes, the machine must stop and restart. The restart current is more than the rated current, even up to 6 times. “Delicate washing” mode consumes more power than “strong washing” mode. If you want to save electricity, try to avoid using the “delicate washing” mode.

No. 7: Microwave

Microwave ovens, like washing machines, don’t consume much power during standby. Unexpected power consumption is actually on the food. Because the principle of the microwave oven is to heat the food by heating the water in the food. If the food is drier, the heating time will be longer and the electricity consumption will be higher.

You can try sprinkling a little bit of water when microwaving dry food, and adding a lid can shorten the heating time and reduce power consumption.

No. 6: Rice cooker

A rice cooker is a must-have appliance for Asian households. It is small in size, but its power consumption can be similar to that of a small air-conditioner! It consumes 1 kW of electricity in one hour of use. If you turn it into the heat preservation mode, it also consumes a lot of electricity. So, the rice cooker is definitely an unexpectedly high power-consuming appliance.

If you want to use a rice cooker without wasting electricity, you might as well soak the rice for 30 minutes before cooking. When the rice becomes soft, the cooking time can be reduced. In addition, heating water to cook rice can also save the time for the rice cooker to heat the frozen water, which can shorten the cooking time by 30% to 40%, and can reduce the electricity used by the rice cooker in a disguised form. Remember to turn off or unplug the rice cooker when you are not using it.

No. 5: Refrigerator

A refrigerator is an electrical appliance that needs to be turned on 24 hours a day. Of course, it consumes a lot of electricity, but in fact, the method of storing food will also affect the electricity consumption of the refrigerator. If you want to use the refrigerator to save electricity, there are two rules for storing food. First, the refrigerator (lower compartment) can only be 70% full, so that there is enough space for cold air to circulate in the refrigerator so that the refrigerator is not used. Use more electricity to keep the temperature cool.

No. 4: Induction cooker, electric ceramic cooker

Fireless cooking is the general trend, while electric stoves have become a cooking tool for most people. They cook with electricity, so they are also one of the electrical appliances that consume electricity. Generally, the plug of the induction cooker is also installed in the kitchen cabinet and few people will consider adding a switch. However, the induction cooker still consumes electricity in the standby state, so if you want to save electricity, you may wish to add a switch to allow you to turn it off when not in use to reduce power consumption.

In addition, the emerging electric ceramic stove also consumes more power than the induction cooker, because the principle of the electric ceramic stove is to heat the surface up, and then it takes time to transfer the heat to the cooking container. The operation of the induction cooker is relatively simple and direct, so if the power of both parties is the same. The induction cooker also saves more electricity than the electric ceramic cooker.

No. 3: Air Conditioner

Air-conditioners are definitely a big power-consuming appliance in summer. Here are some ways to use an air-conditioner in a power-saving way while keeping cool:

  1. Choose an inverter air conditioner, which automatically adjusts the output air conditioner, unlike the fixed frequency air conditioner that stops operating after reaching a certain temperature, and then restarts after a certain temperature. After all, every startup requires electricity, and it consumes the highest electricity when it is turned on and off. So, using an inverter air conditioner is a better option.
  2. Clean the filter regularly to avoid affecting the cooling effect, and then increase the cooling of the air-conditioning.
  3. When the air conditioner is turned on, the air outlet should face upward, and the fan or circulation fan can be used to accelerate the indoor cooling temperature drop.

No. 2: Electric water heater

Electric water heaters give you a warm hot bath that is refreshing, but on the other hand, it is a power-consuming appliance! The heating process power of the electric water heater can reach kilowatts, and it can use more than 1 kW in just 10-20 minutes. If it is turned on for a long time, it will consume a lot of electricity every day, so be sure to turn it off when it is not in use.

No. 1: Set-top box

The set-top box actually comes first on the list. It turns out that the operating power of this small appliance is almost the same as the standby power! Therefore, it is an electrical appliance that consumes electricity 24 hours a day like a refrigerator. It consumes 10 kW of electricity in one month. So, be sure to completely cut off the power supply of the set-top box when not in use.


The above are 8 unexpected power-consuming electrical appliances. If you don’t want to waste electricity unknowingly, you should completely cut off the power when you are not using the appliance.
