Many appliances continue to use electricity even when they are shut off. The same goes for all those chargers, whether or not they are charging a smartphone. Everything you leave plugged into an outlet—appliances, computers, consoles, chargers, lamps, and more —draws energy even when not in use.
The average home has dozens of items plugged in at any given time. What's more, 75 per cent of the electricity these devices consume is used when they aren't even on. That's a lot of energy. In fact, all that phantom power can add up to 10 per cent of a home's energy costs.
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.
Your computer uses zero energy when "off." That's true only if it is unplugged. Otherwise, the PC utilizes "flea power," or about 2.3 watts, to maintain local-area network connectivity, among other things, McCall says. In "hibernate" mode, your PC uses the same 2.3 watts; in "sleep" mode, your PC uses about 3.1 watts.
All chargers will draw a small amount of electricity, even when a device is not connected.

Yes. Like most devices, your TV draws a small amount of electricity even when it's off. Most TVs use about 1.3 watts in standby mode, or about 2-5% of the wattage required when turned on. It's a small amount of power, but devices like TVs have a big impact nationwide.
Not all types of toasters have a phantom load. The old-fashioned ones, such as pop-up toasters that don't have clocks or LED displays, don't consume electricity after you've turned them off. However, if you have a fancy toaster with a timer or display, you'll need to unplug it if you want to turn it off completely.
The short answer: Yes. Even when devices are off or in standby mode, they still use power, known as “phantom loads” or “vampire electricity.” While unplugging many devices could help reduce your energy usage, not every electronic or small appliance in your home needs to be unplugged.
Heating and cooling: 45-50%
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.
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.
However, your microwave will always draw a little power even when it isn't in use. There are additional benefits to unplugging your devices. First, you can reduce the wear of the device by keeping it unplugged. This can extend the life of your appliances, so you don't have to buy new ones as often.
Just using the sockets on/off switch isn't safe because the switch could be broken. If left plugged-in, many appliances still have power flowing through them even though they look like they are off. The same is true of equipment in 'sleep mode' or on 'standby'.
Yes, appliances still draw electricity even when you think they're off! It's true! Even if an appliance is turned off, it's still using a small amount of power if it's plugged into an outlet. Believe it or not, even if you think an appliance is completely turned off, it may still be using a little bit of electricity.
Basically, a lamp does not consume electricity when it is switched off. However, it is different with lights in standby mode, which have a power consumption of about 0.50 watts per lamp even when switched off.
How much electricity do appliances use when turned off? Some device may take just a small amount of energy but it's always wise to unplug, especially older inefficient products. The average amount of energy consumed by gadgets on standby or in a non-active state between 9% and 16% of a home's total energy bill.
Electronic devices use power when they're plugged in, even if they're not turned on. Unplugging large appliances such as your refrigerator, range, and dishwasher would be unwise, and difficult to do as well, and anything with a clock that needs to be reset after a power outage should be left alone.
Energy-saving power strips stop devices from wasting electricity as they continue to draw power even when turned off.
Like other electronics, TVs remain in standby mode when not in use. This means that any device that is plugged in will continue to draw a small amount of electricity from the outlet because it is always ready to be turned on.
Your TV's components need plenty of time to rest in between uses. The best thing you can do for your TV is to turn it off when you're not using it!
According to the U.S. Consumer Product Safety Commission , “Unattended, plugged-in appliances may create an unnecessary risk of fire”.
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.
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.
