How much electricity does a TV consume per hour?

Televisions appeared relatively recently, but have deservedly become necessary in everyday life. Every home now has this source of news, entertainment, political debates, scientific debates and sports shows. When purchasing, they usually take into account the newness of the model, weight, and diagonal size. But no one pays attention to the amount of energy consumed. But in vain, because the quantity can be quite large. Nowadays you can find devices that use electricity very economically.

How many watts does a TV consume per hour?

There are three types of “blue screens”, each of which consumes a different amount of kilowatts:

1. Plasma TV.
2. Liquid crystal devices.
3. Cathode ray tube devices.

Typically, TVs work for a long time, and they are not unplugged from the socket, leaving them in standby mode. Of course, on TV you can watch your favorite series, economic and medical programs, detective stories and concerts. The operating time of each TV is purely individual, depending on the needs and interests of the family. Some rarely come to the “blue screen” because they are very busy, others do not look away from it for days. You should approach information selectively, taking into account your lifestyle.

You can measure the electricity consumed yourself if you have a device called a wattmeter. It instantly takes power readings. It is best to use a household wattmeter that plugs into an outlet. It will measure, remember, and some will calculate the cost of consumed electricity. To do this, just enter data on 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 operating hours affect the invoice. As a rule, it takes about 5 hours to watch TV every day, and 150 hours in 30 days. If there are 31 days in a month, then there are 155 hours.

How much does plasma TV consume?

In some ways, plasma panels are considered one of the best achievements of modern technology. Indeed, image, sound, contrast, color are transmitted at a high, quality level. But the electricity consumption is quite high.

How much electricity does the TV consume per hour? The electricity consumption of a TV per hour, with a diagonal size exceeding 42 inches, is about 150–190 W/hour.

How many kilowatts does the 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 device is slowly becoming a thing of the past. Power consumption depends on screen size. For example, if the diagonal is less than 32 inches, then the power supply will be about 40–55 Watts/hour. Standby mode will consume 1 Watt. How many watts does the TV consume? Within a month the numbers will increase to 7–9 kW.

LED panels use electricity sparingly. This is a subtype of LCD that consumes 40% less power. In standby mode, 0.3 watts are consumed here. If the diagonal is 49 inches, then the energy consumption will be 100–150 Watt/hour. In a month, an LCD TV will “eat up” 15–23 kW.

Consumption of cathode ray tube TV

The energy consumption of a TV with a picture tube, which has a long service life, ranges from 60 to 100 watts per hour. In one day, such a device can “eat up” 0.5 kW. For a full month of using the device, electricity consumption will be 15 kW.

These TVs, whose power is quite high, were the first to appear on the market. Our grandmothers, grandfathers, great-grandmothers, great-grandfathers were the first to meet the then new models, along with radios and refrigerators. Back then these were technical innovations, a production miracle.

How many kilowatts does a TV consume per month?

How many kilowatts does the TV consume? The power supply of the device depends on its model, type, diagonal size, operating time, and losses in standby mode. Depending on the listed criteria, 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 cathode ray tubes “eat up” 16–18 kW.

Each brand also responds differently to market needs and the environmental picture. Therefore, indicators may also vary depending on this factor. Consumption of brands Samsung, LG, Alfa, Thoshiba, Sony may not be the same, but not very significant.

How much does the TV consume in standby mode?

How much does the TV consume in standby mode? Devices that are constantly plugged in are commonly called “home vampires.” In standby mode, each type incurs its own losses:

1. Plasma panels lose 0.5 Watt per day, 15–16 Watt per month.
2. Liquid crystal displays consume 1 Watt per day, per month - 30-35 (diagonal less than 32 inches) and approximately 5 and, respectively, 60 watts (with a screen size of 49 inches).
3. With a cathode ray tube, 2–3 Watts are consumed per day, and 62–93 per month.

How much electricity does the TV consume in standby mode? Recently, brands have begun to release new electrical appliances labeled “A”. This means the product is energy efficient. Pluses can be added to the letter: “A+”, “A++”, “A+++”. The more advantages, the more electricity is saved.

Environmentalists on the planet recommend saving energy. This can be achieved if:

• 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 the TV in a room with even lighting (brightness and contrast settings can be minimized and save 5%);
• Do not leave the device in standby mode (pull out the cord from the outlet).

A new range of products has appeared that have unique qualities.
