How much electricity does a TV use? Generally, TVs use between 50 to 200 watts (W) of electricity, depending on the model. Most TVs use less than one amp and connect to a 120-volt outlet. Older TVs that use technology such as Plasma and CRT are much less efficient compared to newer LED and LCD TVs.
First of all, you need to know how many watts your tv uses. If your tv uses 100 watts per hour and the electricity runs 12 cents per kilowatt hour then it costs 1.2 cents per hour to run. That's 28.8 cents per day or $8.64 per month to run it 24/7.
a 55-inch LCD TV typically uses around 180 watts, while an LED TV consumes about 80 watts. For an OLED TV, the usage is around 98 watts, whereas a plasma TV requires approximately 370 watts.
The short answer is that it depends on your kind of television and how big it is. It's also important to consider how long you're leaving your TV on each day. The more hours it's on, the more electricity it's using.
Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
Any appliance with an LCD, light, or clock, such as your DVD or DVR player, cable box, television, or microwave, consumes electricity even when turned off. Sleep or standby power mode devices are never entirely turned off; instead, they go into standby mode.
Most modern TVs consume between 50 and 200 watts on average. The power usage of a TV depends on its type, size, and how frequently it's used.
A home refrigerator's power consumption is typically between 300 to 800 watts of electricity, or between 3 and 6 amps and about 120 volts. Importantly, refrigerators generally have a much lower "running" wattage than their stated average wattage – this is because they cycle on and off throughout the day.
If you're not using your TV, the best practice is to simply turn it off! Of course, the longer you leave your TV on, the more power it ultimately consumes. If you leave your TV powered on, whether you're watching it or not, you might see an increase in your electricity bills.
Air conditioner usage varies based on the size of your AC. However, generally speaking, a central air conditioner will consume between 3000 and 3500 watts per hour. While window units use between 900 and 1440 watts per hour, portable units consume between 2900 and 4100.
On average, hair dryers use about 1,500 to 2,000 watts of electricity. Using a hair dryer for 10 minutes per day will use about 9.13 kilowatt-hours of electricity per month and 109.5 kilowatt-hours of electricity per year. A hair dryer costs an average of $1.30 to use for a month and $15.54 to use for a year.
Generally, you should aim to turn your TV off whenever it's not in use, not just overnight. Don't forget that your TV occasionally needs a break. Leaving your TV on 24/7 would lead to the components of the TV being overloaded. This will cause significant damage over time.
ENERGY USAGE
Depending on the size of the TV and how much you watch, you could use as much as 500 watts over the course of a year. That adds up to about $100 in power bill costs for your TV alone. A seemingly small portion of your total power bill, but it all adds up.
If you have electric heat, heating your home uses the most energy. This can account for more than 30% of your electricity consumption. And if you have air conditioning, this number rises even higher. All told, your efforts to stay comfortable can use between 40% and 50% of the electricity in your home.
Research shows that, on average, modern TVs use approximately 58.6 watts when they're “on” or in use, and approximately 1.3 watts in standby mode. This rate of usage is higher than appliances like refrigerators, washing machines, and clothes dryers.
If you have a 2100W (2.1 kW) washing machine and you run it for an hour, it'll use 2.1kWh of electricity in that hour. If electricity costs 34p per unit, multiply 2.1kWh by 34p and you get a grand total of 71p.
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
In other words, does leaving a plug socket on use electricity? An empty plug socket does not use any electricity, because the current has nowhere to flow unless there's a plug completing the circuit and an appliance switched on. So you do not have to go round turning every socket to the off position.
Unplug Your Appliances for Safety
Leaving appliances plugged in increases the risk of fires. Consumer Reports studies show that about half of appliance-related fires are due to issues with the appliances themselves. Often, this happens when an appliance has been recalled, but the owner isn't aware of the recall.
A switch breaks the circuit, so effectively the same as unplugging an appliance. But it may not stop a surge.
