Coffee makers. Television sets. Washing machines. Practically every appliance and electronic device you have plugged in at home is using some electricity — and adding to your utility bill — even when it isn't in use or even turned on.
Electronic devices, such as a phone, tablet, TV, dishwasher or washing machine still use energy while on standby whatever the weather. Savings can be made just by remembering to unplug them. A saving of around £20 a year could be made if you switch off your set top box at the wall when it's not in use.
Everything that is connected to power will use some energy. Because it's so often connected with equipment in standby or inactive mode, standby electricity loss is also known as phantom or idle electricity.
But let's take a look at what happens when you leave something plugged in and switched on. According to the Energy Saving Trust, any switched on charger that is plugged in will still use electricity, regardless of whether the device is attached or not.
But many common household devices switch to “standby” mode instead of being actually OFF. TVs, game consoles, cookers, microwave ovens. In fact, a typical microwave oven uses more electricity each year to power its clock than it uses to cook food.
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.
How much electricity does a washing machine use? On average, a washing machine uses 400 to 1,400 watts (W) of electricity, depending on the model. Most washing machines use between 5 and 15 amps and connect to a 120-volt outlet.
Did you know that when your appliances or electronic devices are plugged in, they're draining energy – even if they're not in use? Phantom power, also called standby power, refers to the energy that's wasted around your home when devices are plugged in and using power, but you're not actively using them.
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.
Turning off your appliances at the wall won't magically cut your power bill in half, but it can help you further conserve energy and save on electricity. Every little bit counts!
A switch has two states Open or closed When a switch is open no current can flow through it. When a switch is closed current flows through it.
According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.

A switch breaks the circuit, so effectively the same as unplugging an appliance. But it may not stop a surge.
Standby Power Consumption
Research suggests that phone chargers typically consume around 0.1 to 0.5 watts of electricity when they are plugged in but not actively charging a phone. While this may seem like a negligible amount, the cumulative effect of multiple chargers consuming standby power can add up over time.
Standby power, sometimes referred to as phantom power, is energy consumed by appliances when they aren't technically 'on'. So, it might be a television that's turned off but could be fired up by pressing the remote. Or, a washing machine that isn't doing a load.
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.
An empty clothes dryer requires less energy output and doesn't pose any extra risks.
1. Washing Machines & Dryers. At eight loads of laundry a week, the average family uses both the washing machine and the dryer six hours each on average per week. Even with some of the more energy efficient models, the combined cost of doing laundry can add up to more than $115 a year for the electricity alone.
A single wash cycle of a fully-automatic washing machine electricity consumption can be around 1-1.5 units of electricity. Washing machine unit consumption per hour ranges from 0.5-1.5 kWh depending on the model, cycle, and load size. On average, your standard washing machine power consumption is 0.2-0.3 kWh per hour.
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.
Other high-power appliances are the water heater, the refrigerator, and the washer and dryer. These aren't appliances that you can unplug to save energy. Instead, you should look for energy-efficient models that consume less water and power.
Leaving your TV on standby is not likely to result in a fire hazard. However, in the interest of safety, it is strongly recommended to turn your TV off at the wall. Unplugging your TV between uses can help to save a lot of electricity. Even when in standby, a TV continues to consume electricity!
