During the total rise in the cost of utilities, ordinary townsfolk often ask themselves how much electricity they "devour" ordinary and such habitual household appliances: a refrigerator , a microwave oven, a washing machine, an iron, a computer. But, you see, the most popular device evokes special interest, the evening friend of many families - the TV. It's no secret that in many families the "blue screen" works from morning till evening / night. In addition, most homes do not even use one TV, but several: in the kitchen, in the bedroom.
It is worth mentioning that TVs have a parameter that characterizes the amount of electricity that the device uses per hour of continuous operation, it is energy consumption, or power consumption. So, we will tell you how much power the TV of different types consumes.
What is the power consumption of the TV?
It is quite logical that the power consumption of the TV depends on many characteristics. This, for example, the size of the device, its appearance, additional functions and options, as well as the brightness of the image exhibited by the owner.
By the way, the power of the TV is calculated in watts, or briefly W, multiplied by the operating time - W / h.
To a greater extent, power consumption is determined by the type of "blue device". A modern CRT with a cathode ray tube mainly consumes 60 to 100 watts per hour (depending on the kinescope diameter). If, for example, you watch such a TV every day for five hours a day, then the daily consumed by such a device will be 0.5 kW / h, and a month - 15 kW / h.
Now let's talk about other types of modern TVs.
Most of all from "thin" brothers the power of a plasma TV. Power consumption of the device with a large diagonal reaches 300-500 watts per hour. As you can see, a plasma screen consumes 1, 5-2.5 kW per day for five hours of viewing, and, correspondingly, 45-75 kW per month. Agree, a lot. But, the quality of color reproduction of plasma TV at the highest level!
If we talk about the power consumption of LCD TV , then this figure is much lower. The device with 20-21 diagonal consumes only 50-80 W per hour, and, accordingly, 0, 25 kW / h and 7.5 kW per month. Saving is obvious! However, devices with a large diagonal consume much more electricity - 200-250 watts per hour.
By the way, the power consumption of LED TV due to the use of diodes in backlight is usually 30-40% lower than that of conventional LCD TVs.
