In our homes, filled with a growing number of electronic devices, a silent enemy of savings is lurking: standby power consumption. That small, seemingly harmless red light indicating a device is ready for use actually represents a constant and unnecessary drain of energy. This “phantom load,” multiplied by all the devices in a home, 24 hours a day, translates into significant waste that impacts both the electricity bill and the environment. Understanding this phenomenon is the first step to effectively combating it by adopting targeted strategies that combine established habits and innovative solutions.
The issue of standby power consumption is not negligible. According to various estimates, it can account for up to 10% of an average family’s energy bill. ENEA (the Italian National Agency for New Technologies, Energy and Sustainable Economic Development) calculates that a single device on standby can consume from 1 to 4 watts per hour. When you consider the number of televisions, set-top boxes, computers, video game consoles, and small appliances constantly plugged in, the annual waste becomes considerable, potentially costing up to 152 euros per year per household. This expense not only burdens household finances but also contributes to an increase in global CO2 emissions.
The Impact of Standby: From Kilowatt-hours to Euros
To understand the scale of this waste, it’s helpful to translate the data into concrete examples. A television left on standby for 21 hours a day can consume about 40% of the energy it would use if it were on for 3 hours. Even a simple PC monitor can waste up to 10 kWh per year, while a TV can reach 50 kWh. Appliances like a microwave oven, with its always-on digital display, can consume about 27 watts per hour continuously, and a set-top box can draw up to 10 watts in standby mode. Summing up the contributions of all devices, the average standby consumption per household in Europe is estimated to be around 305 kWh per year, equivalent to about 11% of a family’s total electricity consumption.
Awareness of this hidden cost is crucial. Many people don’t realize that even chargers left in the outlet, without a device connected, continue to draw power. This constant energy flow, though minimal for each individual appliance, generates a significant economic and environmental impact on a large scale. Tackling the problem requires a change in mindset and the adoption of new habits, a necessary step for concrete energy savings and for protecting the planet’s resources.
Practical Strategies to Eliminate Phantom Loads
Eliminating or drastically reducing standby consumption is easier than you might think and doesn’t necessarily require large investments. The most immediate strategy is to completely turn off appliances when not in use by physically unplugging them from the outlet. To simplify this, especially when dealing with multiple devices grouped together (like a TV corner with a set-top box, console, and sound system), using power strips with an on/off switch is a solution that is as inexpensive as it is effective. With a single flick of a switch, you can cut power to all connected devices, eliminating phantom loads.
Another important habit concerns kitchen appliances. Espresso machines, for example, are among the most power-hungry in standby mode and should always be turned off after use. Even dishwashers and washing machines, if left with the door open, can remain in a pre-start state that consumes energy in some models. It is good practice, therefore, to ensure they are completely turned off and closed. These small adjustments, integrated into daily routines, can lead to a significant reduction in waste at no additional cost.
Innovation and Technology for Savings
In addition to good habits, technology offers innovative solutions to combat energy waste. Smart plugs are an evolution of classic power strips. These devices, controllable via a smartphone app, not only allow you to turn appliances on and off remotely but also to schedule automatic shutdowns and monitor consumption in real time. This way, you can identify the most energy-intensive devices and manage power more efficiently, a step towards affordable and functional smart home automation.
There are also specific devices, such as “standby killers” or “standby stoppers,” that connect between the outlet and the appliance and automatically cut power when they detect the device has been put on standby via remote control. The market also offers new-generation appliances, often certified by standards like “Energy Star,” designed to have extremely low standby consumption. Investing in Class A appliances and high-energy-efficiency models is a choice that, in the long run, pays for itself through savings on your bill.
The European Context and Mediterranean Culture
The fight against energy waste is also a central theme at the regulatory level. The European Union, aware of the impact of standby consumption, has introduced increasingly stringent regulations on ecodesign. Starting May 9, 2025, new rules (EU Regulation 2023/826) will come into force, imposing even lower maximum consumption limits for devices in off, standby, and networked standby modes. For example, a device without a display will not be allowed to consume more than 0.50 watts on standby. These measures, extended to products like Wi-Fi routers and motorized furniture, aim to generate savings of about 4 TWh per year by 2030, with a reduction in CO2 emissions of 1.4 million tons.
In Italy, a country at the heart of the Mediterranean, the culture of saving has deep roots, historically linked to a wise use of resources. This tradition now blends with technological innovation. Initiatives like the “National Energy Saving Day” testify to a growing collective awareness. The Mediterranean approach to living, which favors materials and construction techniques that ensure natural thermal comfort, integrates perfectly with modern energy efficiency strategies. Eliminating standby power thus becomes a piece of a larger puzzle, combining the wisdom of the past with the opportunities of the future for a more sustainable lifestyle.

Frequently Asked Questions
What exactly is standby power consumption?
Standby power consumption, also known as “phantom load” or “vampire power,” is the electricity consumed by an electronic device when it is not in active use but is plugged into a power outlet. This mode allows the device to be reactivated quickly, for example, via a remote control. Typical examples include the red light on a television, the digital clock on a microwave oven, or set-top boxes that remain ready to receive signals. Although the consumption of a single device is low, the sum of all devices on standby in a home can account for up to 10% of the total bill.
Which appliances consume the most in standby mode?
Not all appliances consume the same amount in standby mode. Among the most energy-intensive are set-top boxes (both satellite and digital terrestrial), video game consoles, desktop computers (which can reach 10-15W), modems and Wi-Fi routers, and microwave ovens, whose displays can draw up to 27 watts per hour. These are followed by televisions, stereo systems, and coffee machines. Even smartphone and laptop chargers, if left plugged in after charging, continue to waste energy. It is important to pay attention to these devices to maximize savings.
How can I immediately reduce standby power consumption in my home?
There are several immediate and effective strategies. The simplest is to unplug appliances that you don’t use frequently. For devices used daily, like TVs and computers, a practical solution is to plug them into a power strip with an on/off switch: this way, you can turn them all off at once with a single gesture. Another good habit is to completely turn off appliances like the coffee machine and the Wi-Fi router overnight or when you’re away from home for long periods. Using programmable smart plugs can further automate this process, ensuring consistent savings without effort.
Will the new European regulations eliminate the standby problem?
The new European regulations, which will come into effect starting in May 2025, are a significant step towards drastically reducing the problem, but they will not eliminate it entirely. Regulation (EU) 2023/826 imposes much stricter consumption limits for new products placed on the market. For example, standby power consumption for devices without a display must not exceed 0.50 watts. While this will significantly reduce the waste from future appliances, it will not affect the millions of devices already in homes. Therefore, good habits and active saving strategies by consumers will remain essential to completely eliminate phantom loads.
