A subtle charge, but one that matters: standby power adds up—and it’s worth managing.
Mexico City, August 7, 2025 — Even when switched off, Smart TVs continue to draw a small amount of electricity if left plugged in. This so-called “phantom” or “standby” power averages between 1 and 3 watts per day on most modern models, while older units can reach up to 5 watts. Over a year, this translates into roughly 21 to 33 kilowatt-hours—about two euros annually in countries with energy prices similar to Spain’s. While the individual cost may seem minimal, the cumulative effect across multiple devices in a household can become significant.
Standby energy, often referred to as “vampire power,” represents more than a technical curiosity. In many homes, it accounts for between 5% and 10% of total annual electricity consumption, with some studies estimating an average of one hundred U.S. dollars per household per year in wasted energy. International efforts, such as the “One Watt Initiative” backed by the International Energy Agency, have pushed to limit standby draw to less than 1 watt per device, aiming to reduce both economic waste and environmental impact.
Today’s Smart TVs generally consume between 0.5 and 3 watts in standby mode, and rarely exceed 5 watts even in older configurations. This marks an improvement over models from a decade ago, which often used significantly more. European energy efficiency regulations now set even stricter limits, mandating a maximum of 0.5 watts for future-compliant devices. This adjustment could save up to 3.65 kilowatt-hours per TV annually, assuming the device remains plugged in but unused for around 20 hours per day.
The difference between active and standby consumption is stark. While in use, a television can draw anywhere from 30 watts to more than 200 watts, depending on its screen size, display technology, and brightness settings. This means that while standby power is far lower than active use, it still represents an unnecessary energy drain when multiplied across millions of homes.
Beyond televisions, the same silent consumption pattern appears in other electronics: routers, gaming consoles, set-top boxes, and even some kitchen appliances. In countries like Spain, a single television in standby can contribute between 7 and 15 kilowatt-hours to monthly energy bills, adding several euros over time. The combined load of multiple devices left in standby throughout the year can therefore result in both higher costs and avoidable carbon emissions.
Energy specialists recommend simple countermeasures: unplugging devices when not in use, especially before extended absences; using power strips to disconnect multiple electronics at once; or installing smart plugs that can automatically cut power after set periods of inactivity. These steps are not only beneficial for reducing standby waste but also help protect equipment from electrical surges and extend its lifespan.
Ultimately, turning off a TV at the button is not the same as disconnecting it from the grid. For households aiming to minimize their energy footprint, addressing standby power is an easy, low-cost first step. In the context of rising energy prices and global environmental concerns, eliminating this passive consumption is both a practical and symbolic act: it acknowledges that energy efficiency is no longer confined to industrial policy or large-scale infrastructure but begins at home, one plug at a time.
