Common sense of life: the router is on all day! How many kwh of electricity is consumed a year?

The router is on all day. How many kwh of electricity is consumed a year? Now our cats and routers are basically turned on 24 hours a day. How many kWh do we consume every day?

Cats and routers are basically powered on for 24 hours. How many kWh do they consume every day? There is a test conducted by a special person. Let's take a look at the actual measurement of a special person:

Actual measurement: the cat and router are * * * 7.9W, so that 0.0079 times 24 times 30 is 5.688 kWh per month. Suppose 1 kwh is 50 cents, then multiplying 5.688 by 0.5 is 2.844 yuan per month. The annual electricity consumption is 2.844 times 12, which is equal to 34. 128 yuan.

Ordinary desktop computer

It was measured with the router during the test, so the actual power consumption of the computer should be 83.4-7.9 = 75.5 W.

Television box

Many people's TV boxes are also open 24 hours a day. What is its power consumption?

The power consumption of TV box is 6.6W, which is lower than that of cats and routers.

television

Since the set-top box has been measured, it is better to measure the power consumption of the TV set.

Tsinghua Tongfang,

42-inch TV refrigerator with power consumption 107.8W

Hisense 226 liter double-door refrigerator. The power consumption during cooling is 7 1.8W, and in general, it is 0W. Do you know why the refrigerator is not very power-hungry? )

Although the power consumption of household appliances is getting lower and lower now, the old urchin still advises everyone to turn off all unused household appliances.
