Nowadays, having one or more televisions in our home or office is essential for entertainment and security in companies. However, the amount of watts of power they consume varies according to type and Screen size. So, how many watts does a TV use? The average is between 45 and 65 W and h in 20-inch LCD TVs. The 32-inch is between 115 and 160 W/h; the 37-inch with a consumption of 150 and 200 W/h.

In CTR or tube televisions, consumption varies between 50 and 60 W6/h for 21-inch and 70 and 130 W/h for 29-inch. On the other hand, a plasma screen TV consumes about 30% more electricity than LCD screens. On the other hand, the led tends to consume 40% less if we compare it with the LCD.

What is the Power Consumption of CRT TV versus LED TV in Watts?

There are cases of people who still use CRT televisions because they already have them or are resistant to change. Therefore, they do not believe it is necessary to replace it.

However, the consumption of a CRT TV compared to a LED is significant due to their different design structures and functionality. The CRT; is a system formed by cathode ray tubes containing vacuum and the electron. Thus, it requires a considerable amount of watts for optimum performance. On the other hand, the LED is made up of light-emitting diodes that work with the current flow, needing a minimum amount of watts. For example, a 19-inch LED TV consumes 300% less than a CRT TV of the same size.

If I turn on a 60-kilowatt bulb for 1 minute, have we used 1-kilowatt hour of electricity?

Do Appliances on Standby Consume Energy?

The standby cycle of any appliance generates a minimum energy consumption, which it needs to respond to the user’s call instantly, without waiting to charge all its functions. The difference when it is turned off is that all its functions are disconnected. In standby mode, on the other hand, they are in unnoticeable operation, waiting to be executed. In this way, a small charge is necessary to execute its functions instantly. This is generated by pressing any button on the device.
