Many appliances continue to drain electricity even when they are turned off, by running in standby mode. This is sometimes referred to as phantom or vampire energy. Cable boxes, for example, spend their downtime updating cable guides and software, and their internal drives are constantly moving. To find out what is soaking up electricity, you can use a device that plugs into the same electrical outlet as your appliances to measure electricity usage. Alternatively, you can install a system that works with your meter to monitor usage in real time. For those with smart homes, smart plugs with built-in energy monitoring are also available.

What You'll Learn
Use a device like Kill-A-Watt to monitor appliance electricity usage
If you're looking to monitor your appliance electricity usage, a device like the Kill A Watt meter is a great option. This simple tool can help you identify power-wasting appliances and determine whether they're worth keeping plugged in.
To use the Kill A Watt meter, simply plug it into an outlet, and then plug any appliance into the device. It will then display how much energy the appliance is consuming in real time, allowing you to calculate its energy usage over different periods. The device measures various factors, including wattage, voltage, line frequency, current, and power factor. This information can help you identify any problems with your electrical system, such as loose wiring or faulty appliances.
The Kill A Watt meter is an excellent way to reduce your power bill and increase your awareness of energy consumption. It can help you decide if it's time to replace certain appliances, such as an old refrigerator or air conditioner, with more energy-efficient models.
You can purchase the Kill A Watt meter from Amazon for under $40, or you might be able to borrow one from your local library. It's a straightforward and budget-friendly solution to help you understand your energy usage and make more informed decisions about your appliance usage and purchases.

Compare power readings over a specific period of time
To compare power readings over a specific period, you can use a plug-in energy monitor. These devices are plugged into the electrical outlet and then you plug the appliance into the monitor. It will then display how many watts the device is using. You can leave it set up to see how many kilowatt-hours (kWh) of electricity the device uses over time. Some monitors will even calculate the cost of running the device based on your utility tariff.
You can also compare power readings by calculating the wattage and hours used per day, and then dividing by 1000 to get the daily kilowatt-hour (kWh) consumption. You can then multiply this figure by the number of days the appliance is used per year to get the annual energy consumption. Finally, multiply the annual energy consumption by the utility rate per kWh to get the annual cost of running the appliance.
For example, if you use a kettle for one hour every day, you can calculate the daily energy consumption with the formula: Wattage x Hours Used Per Day / 1000. Let's say the kettle has a wattage of 3000W. The daily energy consumption would be:
3000 x 1 / 1000 = 3 kWh
To get the annual energy consumption, multiply the daily consumption by the number of days the kettle is used per year. Assuming the kettle is used every day, the formula would be:
3 kWh x 365 = 1095 kWh
Finally, to get the annual cost, multiply the annual energy consumption by the utility rate per kWh. If the utility rate is $0.10 per kWh, the formula would be:
1095 kWh x $0.10 = $109.50
So, the annual cost of running the kettle for one hour every day is $109.50.
Another method to compare power readings is to use an ammeter to measure electricity in amperes (amps). You can then use the formula Watts = Amps x Volts to calculate wattage. For example, if the ammeter reading is 3 amps and the voltage is 120V, the wattage would be:
3 amps x 120V = 360W
You can also compare power readings by looking at standby power consumption. Many appliances continue to draw power when switched off, which is known as "phantom load" or "vampire energy". Cable boxes, for example, use standby power to update cable guides and software, and their internal drives are constantly moving. According to a study by the Natural Resources Defense Council (NDRC), cable box standby power usage averaged 16 watts.

Check your electric meter and service panel
To find out what's using the most electricity in your home, you can check your electric meter and service panel. Your meter keeps track of how much power you use over time in kilowatt-hours (kWh). A standard meter is a clock-like device that records the amount of electricity you use. Some meters have LCD displays, while others are mechanical.
Smart meters, such as the Landis+Gyr meter, securely capture and store energy-usage data using digital technology. They record and automatically send your energy use to your energy provider. Smart meters give customers better control over their energy usage and budgets.
To locate your main electrical service panel, look for a grey or metal box mounted on a wall in an area away from the main living spaces, such as a garage or the exterior of your house. The main electrical service panel is often called the breaker box. Inside the panel, you'll see multiple switches (circuit breakers). The main circuit breaker controls the electricity supply to your entire home and is usually at the top or bottom of the panel. It is often labelled "Main" or "Service Disconnect" and will have a number indicating the amperage (e.g. 100, 150, 200).
You can systematically turn off circuits at your electrical box while watching the effect on your meter. After locating the circuit pulling the most power, unplug devices from that circuit to discover which appliance is using the most electricity. You can also use an ammeter to measure electricity in amperes (amps).

Contact your electric company for advice
If you are concerned about high electricity usage, it is a good idea to contact your electric company for advice. They are best placed to advise you on how to check what is causing the high usage. For example, they may suggest that another property is hooked up through your meter, or that your meter is defective. They may also advise you to check your appliances to ensure none have gone haywire and are using more power than they should.
Your electric company may also be able to advise you on how to reduce your electricity usage. They may be able to conduct a home energy audit, sometimes for free, and identify ways to reduce your energy usage. They may suggest checking for faulty seals on windows and doors, or leaky ductwork, which could be draining energy. They may also be able to advise on rebates and assistance programs to help you cut costs.
If you are renting, it is worth checking your local laws to see if your landlord is required to include electricity in your rent. If you have access to your home's electric panel, you could also record the energy consumption over a long period of time, such as weeks or months, to check for errors in the meter.
If you are looking to reduce your electricity bill, there are several steps you can take. Firstly, you could look to improve your energy efficiency. This could include ensuring your dishwasher and washing machine are full before running them, and running your washing machine at a lower temperature. You could also avoid using your tumble dryer, which is one of the most expensive appliances to run, and instead use a drying rack or outdoor maiden.
Other ways to reduce your electricity bill include insulating your hot water cylinder, switching off standby mode, taking shorter showers, and switching to LED lighting. You could also use the energy saver mode on your devices and appliances, and enable power-saving features such as "auto power down".
