Televisions appeared relatively recently, but they have deservedly become necessary in everyday life. Every home now has this source of news, entertainment, political debate, academic debate, and sports shows. When buying, they usually take into account the novelty of the model, weight, diagonal size. But no one pays attention to the amount of energy consumed. But in vain, because the amount can be quite large. Now you can find such devices that are very economical in consuming electricity.
How many watts does the TV consume per hour
There are three varieties of "blue screens", each of which consumes a different number of kilowatts:
- Plasma TV.
- Liquid crystal devices.
- Devices with a cathode ray tube.
Typically, TVs work a lot of time, but they do not turn them off from the outlet, leaving in standby mode. Of course, on TV you can watch your favorite series, economic and medical programs, detectives and concerts. The operating time of each TV is purely individual, depending on the needs and interests of the family. Some rarely approach the “blue screen” because of strong employment, while others do not break away from it for days. Information should be approached selectively, given your lifestyle.
You can measure the consumed electricity yourself, if there is a device called a power meter. It instantly measures power readings. It is best to use a wattmeter for domestic use, which is inserted into a wall outlet. He will measure, remember, and some will calculate the cost of electricity consumed. To do this, just enter the current price per kilowatt.
You can also look at the technical specifications of your TV. The manufacturer informs about the amount of electricity consumption at maximum power, and in standby mode. The type of TV and the operating time affect the invoice issued on the invoice. As a rule, it takes about 5 hours a day to watch TV shows, and 150 hours for 30 days. If the month is 31 days, then 155 hours.
How much plasma TV consumes
In a sense, plasma panels are considered one of the best advances in modern technology. Indeed, the image, sound, contrast, color are broadcast at a high, quality level. But electricity consumption is quite large.
How much electricity does the TV consume per hour? Electricity consumption by the TV per hour, with a diagonal exceeding 42 inches, is about 150-190 W / hour.
How many kilowatts does a TV consume per month? Further calculations show that the plasma device consumes about 24.4 - 28 kW per month.
How much does LCD TV consume
How much energy does the TV consume per hour? This type of appliance is slowly falling into the category of the past. Power consumption depends on screen size. For example, if the diagonal is less than 32 inches, then the power will be about 40-55 watts / hour. Standby "eat" 1 watt. How many watts does the TV consume? In a month, the figures will increase to 7-9 kW.
LED panels are energy efficient. This is a subspecies of the LCD that consumes 40% less power. In standby mode, it takes 0.3 watts. If the diagonal is 49 inches, then the energy consumption will be 100-150 watts / hour. For a month, LCD TV "eat" 15-23 kW.
Cathode ray tube consumption
The power consumption of a television with a kinescope, which has a long service life, ranges from 60 to 100 watts per hour. In one day, such a device can "eat" 0.5 kW. For a full month of using the device, electricity consumption will be 15 kW.
These TVs, whose power is quite high, appeared first on the market. Our grandparents, great-grandmothers, great-grandfathers were the first to meet new models then, along with radio and refrigerators. Then it was a technical novelty, a manufacturing miracle.
How many kilowatts a TV consumes per month
How many kilowatts does the TV consume? The power of the device depends on its model, variety, diagonal size, operating time, standby losses. Depending on the listed criteria, the energy consumption is:
- plasma (if the diagonal is more than 42 inches, then 24 - 29 kW);
- liquid crystal (with a screen size of less than 32 inches, then 7-9 kW. With a diagonal of 49 inches, then 15-23 kW. LED devices are the most energy-saving);
- TVs with a cathode ray tube "eat" 16-18 kW.
Each brand also reacts in its own way to the needs of the market, the ecological picture. Therefore, indicators can also vary from this factor. Consumption of brands Samsung, LG, Alfa, Thoshiba, Sony may not coincide, but not very significantly.
How much does the TV consume in standby mode
How much does the TV consume in standby mode? Constantly plugged into a device is usually called "home vampires." In standby mode, each type has its own losses:
- Plasma panels lose 0.5 watts per day, 15-16 watts per month.
- Liquid crystals consume 1 Watt per day, 30-35 Watt per month (diagonal of less than 32 inches) and about 5 watts and 60 watts, respectively (with a screen size of 49 inches).
- With a cathode ray tube, 2-3 watts per day leave, per month 62-93 watts.
How much power does the TV consume in standby mode? Recently, brands began to produce new electrical appliances labeled "A". This means that the product is energy efficient. Pluses can be added to the letter: “A +”, “A ++”, “A +++”. The more advantages, the more electricity is saved.
Ecologists of the planet recommend saving energy. This can be achieved if:
- to purchase equipment with economy modes of TV power in watts;
- use devices equipped with presence sensors (if there are no organic creatures nearby, the device will simply turn off);
- install a TV in a room with uniform lighting (brightness and contrast settings can be minimized and save 5%);
- Do not leave the device in standby mode (pull the cord out of the socket).
A new range of products has appeared that has unique qualities.
