You can find the wattage on the compliance label in the Tv(on the back). Calculate How much electricity does a Tv consume? using our Tv cost calculator.
How many kwh does a microwave oven use?
Let's take an example. Suppose your 32 inch Tv uses 50W for 5 hours a day.
So Daily Energy consumption of your Tv
50W × 5 hour= 250 watts.
Monthly Energy consumption of your Tv
So thus 50W × 5 hour × 30 days = 7,500 watts.
Divide by 1000 to convert watts into kilowatt.
250-watt/1000= .25 kWh
7500-watt / 1000 = 7.5 Kwh.
Let assume the electricity rate in your city is 10 cents per kilowatt-hour.
So thus
Daily cost is:- .25*.10=$.025
Monthly cost is:- 7.5*.10=$.75

If we talk about display technology, LCD (Liquid Crystal Display) and LED (Light Emitting Diode) screens dominate the market but the real question is which of these saves more energy? Let us know in detail about the energy consumption of LCD and LED screens to help you make good decisions for our green future.
You may not know, LCD screens use a backlighting system to illuminate the liquid crystals that make up the display and these backlights are usually fluorescent lamps, called CCFL (cold cathode fluorescent lamps), while latest screens also use LEDs but, even with LED backlighting, LCD screens can consume a lot of energy.
This means that whether you're looking at a dark image or something with a mostly black background, the backlight will continue to consume the same amount of energy, which is not a good thing.
On the other hand, LED displays, use LEDs as separate light sources, which emit light when an electric current passes through them. Unlike LCD, LED displays do not require a separate backlight layer, which means they can consume less energy.
LED displays offer greater energy efficiency due to their ability to automatically adjust brightness levels depending on the content being displayed, this feature is called 'local dimming', due to this, the LED brightness in those parts of the screen where black or dark content is. visible can be reduced or even turned off completely, thereby saving energy to a great extent.
Factors that affecting power consumption of Tv
TV Model: If your TV is of a very old model, then it can power 500 watts or more. New advance LED consume less power than LCD and shows good images.
Screen-Size of Tv: The most efficient TVs on the market consume less power.
For example, a 30-inch LED-lit screen as low as 40 watts, bringing your daily costs down to a negligible number. The larger the screen size of your TV, the more energy it will consume.
Refer to the below chart.
Screen type: The power consumption of LED is very low compared to LCD TV because LED TV uses energy efficiency. It saves at least 20-30% of electricity. while CRT and plasma screens typically use about three times more energy as compared to LED
Manufacturer and build quality: LCD screen is more energy-efficient and is considered safer than CRT.The low power consumption by the LCD also enables it to be used more efficiently in battery-powered electronic devices than the CRT.
LED TV is an advanced version of LCD, with its picture quality is much better. Its lifeline is also much more than LCD. The LED screen is more energy-efficient than an LCD.So the power consumption of your Tv also depends on the technology used by the manufacturer.
There are many types of TVs in the market and people get confused about which TV is the best and which TV should be bought.
If you know the difference between these TVs then you can choose the right TV for you. Many times people choose a shopkeeper or a friend to choose an LCD or LED because they do not understand which TV to buy.
People do not know much about LCD and LED. Here we are going to discuss some differences between them. Which will make you easier to understand.
LCD Tv
Let us tell you that the full name of LCD is liquid crystal display, is a flat panel display that utilizes the light modulating properties of a liquid crystal
Each crystal produces a small piece of the image. When all the crystals combine, we see a big image. Crystals are also commonly called pixels. It consumes less power as compared to a normal TV.
LCD is primarily a flat-panel display of a TV. It was discovered by George H. Heilmeier, an American electrical engineer. Both types of televisions work on this display.
In this technique, small liquid cells are used, from which light comes out and creates a picture.
Red, green and blue colors are used in LCDs. LCD is used in monitors, televisions, the panel of devices as well as many devices used in common life.
LED-backlit LCD, it is a kind of flat panel display.
Apart from TV, LED technology is being used in notebooks, mobile phones, DVD players and video games, etc. LED technology is considered many times better than LCD and CRT technology.
LED TVs consume less power than ordinary TVs and LCDs. Apart from this, its picture quality is strong and its life is also longer. The LED works on cold cathode technology.
Plasma TV
Plasma TV is also an alternative to CRT. It is a type of hypertension TV (HDTV). Plasma is a scientific term used to refer to gases such as neon and xenon.
It consists of thousands of small pixels. It uses red, blue and green colors.The display of the plasma is very flat so that it can be installed directly to the wall.
What is CRT Monitor?
CRT's full form is "
cathode-ray tube". Which is a vacuum tube that holds one or more electron guns and phosphorescent screen and is used to display the image.
It modulates, accelerates and deflects the electron beam on the screen to create an image. Images can represent electrical waveforms, pictures, radar targets, or other phenomena.

It is heavy and large. It takes a lot of electricity. Its color is black.
Difference between CRT and LCD
CRT and LCD are the types of Display Devices where CRT is used as a traditional Display Device while LCD is the more recent technology.
CRT integrates two processes light generation and light modulation and is also managed by a single set of components. In contrast, LCD separates two processes from each other which is light generation and modulation.
- The CRT consumes more power while the LCD consumes less power.
- CRT is Black while LCD is White.
- CRT does not have image retention whereas LCD does.
- The LCD monitor is a built-in new technology, now it replaces the all old CRT monitor in the market.
