Many appliances and electronics continue to consume electricity when turned off or left in "standby" mode. This idle energy draw is commonly called "phantom" or "vampire" power. These devices make up about 5% to 10% of a typical household's total electricity use.
Unplug appliances that generate heat (e.g., toasters, air fryers), are rarely used (e.g., blenders), or sit on standby and drain "phantom power" (e.g., TVs, gaming consoles). Prioritize unplugging items to prevent fire hazards and reduce standby energy consumption.
Your home's biggest energy drainer is your HVAC system (heating and cooling). However, if you are asking about individual plug-in devices, water heaters and clothes dryers dominate active energy use, while cable boxes and small kitchen appliances are the worst "phantom" energy vampires.
Water Heater – 14-18% of Energy Use
Heating water for showers, dishwashing, and laundry can be a major energy consumption. Did you know traditional water heaters continuously heat water, even when they are not in use, wasting your energy and money.
Appliances all over the home can draw phantom power. In some cases, such as with smart light bulbs, it's pretty minimal. Entertainment-related devices, like set-top boxes for recording TV shows and gaming consoles, can drain a lot of energy when they're just in standby mode.
Many appliances and electronics continue to consume electricity when turned off or left in "standby" mode. This idle energy draw is commonly called "phantom" or "vampire" power. These devices make up about 5% to 10% of a typical household's total electricity use.
To find out what is draining your battery, you need to identify whether the culprit is a malfunctioning app, a background process on your mobile device, or an electrical fault (parasitic draw) in your vehicle.
In most homes, heating and cooling (HVAC) runs up your electric bill the most, accounting for about 40% to 50% of your total energy use.
It is almost always cheaper to turn the TV off. Modern televisions use minimal power on standby (usually 0.5 to 3 watts), saving you money on your electricity bill compared to leaving the screen active.
Running an oven for 2 hours typically costs between $𝟎.𝟔𝟎 and $𝟏.𝟐𝟎 for electric, or about $𝟎.𝟒𝟎 to $𝟎.𝟖𝟎 for gas.
The biggest energy waster in your home is your HVAC system (heating and cooling). Because it has to condition massive volumes of air to keep your home comfortable, it accounts for nearly 40% to 50% of your entire household's energy consumption.
Idle Appliances
Common culprits include TVs, cable boxes, printers, phone chargers and kitchen appliances. Even when powered down, these idle appliances consume electricity that shows up on your energy bill.
1. Kitchen Countertop Appliances. Get into the habit of turning off kitchen countertop appliances, such as a toaster or electric kettle, before heading to bed.
The most expensive things to run in a house are heating and cooling systems (HVAC), which account for about 40–50% of your total energy consumption.
Yes, flipping the switch off at the wall achieves the exact same power-saving and safety results as physically unplugging the device. Both methods safely break the electrical circuit, stopping the flow of electricity and preventing devices from drawing standby "phantom" power.
The worst appliances to leave on standby are those that drain "vampire energy" (phantom power) or pose fire risks when unattended. The biggest culprits include televisions, microwaves, gaming consoles, and idle chargers.
To lower your electric bill, prioritize unplugging "vampire devices" that draw power even when turned off. Focus on idle kitchen appliances (like coffee makers and microwaves), entertainment centers (TVs, cable boxes, and game consoles), and unused chargers (phones, laptops, and electric toothbrushes).
The daytime soap opera Guiding Light lasted a combined 72 years across radio and television.
Your HVAC (Heating, Ventilation, and Air Conditioning) system is the appliance most likely to double your electricity bill. Accounting for nearly half of your home's energy consumption, drastic weather shifts can cause these systems to run constantly, easily doubling your costs in the summer or winter.
Running a standard fridge freezer typically costs between $0.15 and $0.50 for 24 hours, which equates to about $4.50 to $15 per month.
Set your thermostat to 68°F while awake, and drop it by 7° to 10°F (to about 58°–61°F) while sleeping or away. The Department of Energy estimates that lowering your thermostat by this much for 8 hours a day can cut up to 10% off your annual heating and cooling bill.
The most common parasitic draw is human error, specifically interior or exterior lights left on (like a dome, trunk, or glove box light). In modern vehicles, the most common mechanical or electrical culprit is incorrectly installed aftermarket accessories (e.g., dash cams, stereos, or alarms wired directly to a constant power source).
Ideally, you should charge your phone when its battery level drops to around 20-30% and unplug it once it reaches 80-90%. There's no specific number of times you should charge your phone in a day; it depends on your usage. Just avoid letting the battery drain completely and frequently charging it to 100%.
The biggest battery drains on a smartphone are its display and cellular connectivity. Specifically, high screen brightness, using mobile data in a low-signal area, heavy 3D gaming, and background apps using continuous location tracking consume power the fastest.
