Between about 5% and 10% of the average household’s total electricity use is attributed to standby power, according to estimates from the U.S. Department of Energy and other energy organizations. While it’s not a new problem, it’s a growing one as households add more connected and smart devices. Let’s explore what phantom loads are, how they affect your electrical consumption, and what you can do about them.
Understanding Phantom Electrical Loads
Phantom loads are electrical loads that occur when you think an appliance is off but it’s still drawing power. The industry also refers to this as standby power or vampire power. Televisions are a common example. When you turn a TV off with the remote, it typically enters standby mode rather than shutting down completely. It continues to draw a small amount of electricity to power features like remote sensing and quick startup. While the wattage per device is usually low, it can add up across the many electronics found in modern homes.
Monitoring Your Home’s Electricity Consumption
Homeowners should track their electricity consumption month to month and year to year. Keeping this record lets you identify sudden surges. In summer and winter, such increases can sometimes be early signs of HVAC inefficiency. Tracking usage also helps reveal the impact of adding new appliances or electronics. You can monitor electricity use through your utility’s online portal, a whole-home energy monitor, or smart panel technology that provides circuit-level data.
Which Devices in My Home Are Prone to Standby Electricity Usage?
Many common household devices use electricity when “turned off” or placed in standby mode. Notable examples include:
- Televisions
- Cable and satellite boxes
- Microwaves with digital displays
- Smart speakers and hubs
- Coffee makers with clocks
- Phone and laptop chargers (when plugged in)
- Streaming devices
- Video game consoles
- Monitors and printers
- Desktop computers
- Appliances with electronic controls
The Impact of Phantom Loads
Phantom loads can impact a household in several ways. They can increase your electric bills, contribute to unnecessary energy consumption, and modestly increase overall electrical demand in your home.
Higher Electric Bills
As mentioned, standby power can account for up to about 10% of total residential electricity use in some homes. Nationally, estimates suggest that standby power costs U.S. households billions of dollars annually, which can translate to roughly $100–$200 per year depending on usage patterns and local electricity rates.
Electrical System Demand
Devices that draw power in standby mode often do so continuously. While the impact of any single device is small, dozens of always-on electronics increase the overall electrical load in a home. In most modern electrical systems, this does not directly cause premature wiring failure, but reducing unnecessary load can still improve overall efficiency and reduce strain during peak usage periods.
Larger Environmental Impact
Standby power represents avoidable energy consumption. Although transportation and HVAC systems are typically larger contributors to household emissions, cutting unnecessary electricity use by even a small percentage can reduce a home’s overall carbon footprint over time.
Which Upgrades Can Help Reduce or Even Eliminate Phantom Loads?
Several devices and upgrades can help reduce standby energy use:
- Smart outlets and plugs
- ENERGY STAR-certified appliances
- Advanced or switched power strips
Smart Outlets and Plugs
Smart outlets and plugs are among the most convenient ways to curb phantom loads. They allow you to schedule power shutoff or remotely disconnect devices that don’t need to run continuously. Many also include energy monitoring features so you can see which devices consume the most standby power.
Power Strips With On/Off Switches
Power strips with built-in switches let you completely cut power to multiple devices at once. Advanced power strips can automatically shut off peripherals, such as gaming consoles or DVD players, when a primary device like a TV powers down. As always, power strips should not be used as a permanent substitute for properly installed outlets if your home lacks sufficient receptacles.
ENERGY STAR
ENERGY STAR is a program administered by the U.S. Environmental Protection Agency and the U.S. Department of Energy. Certified products meet strict efficiency guidelines and are designed to use less energy during operation and in standby mode compared to standard models. Depending on the appliance category, ENERGY STAR products may use 10% to 50% less energy than non-certified models.
LED Lighting
While not a phantom load, lighting upgrades can significantly reduce electricity use. LED bulbs use at least 75% less energy and last up to 25 times longer than traditional incandescent lighting, according to the Department of Energy. Combining LEDs with smart switches or timers can further reduce unnecessary energy waste.
Prep Your Home for Vacations
Many families use more energy than necessary while away from home. If you’ll be gone for 48 hours or more, adjust your thermostat settings appropriately for the season. In winter, keep temperatures high enough to prevent frozen pipes. Many modern water heaters include a vacation mode to reduce standby heating losses. You can also unplug nonessential electronics to eliminate standby consumption. Maintaining moderate indoor temperatures can help protect furnishings and appliances while avoiding excessive energy use.
Do I Need a New Electrical Panel?
Electrical panels don’t create phantom loads, but sufficient panel capacity is important for modern energy demands. Many homes today have 150- or 200-amp service, which is typical for newer single-family residences. You may need an upgrade if you’re adding major appliances, EV chargers, or additional circuits. Signs you may need a panel evaluation include:
- Flickering or dimming lights
- Frequent tripped breakers
- Buzzing sounds from the panel
- Visible corrosion or damage
- Insufficient capacity for planned upgrades
