Appliance Standby Power: How to Eliminate Waste

Autore: Francesco Zinghinì | Data: 7 Novembre 2025

The rising cost of energy is pushing us to find solutions to save on our utility bills. However, we often overlook a crucial aspect: the standby power consumption of appliancesEven when they seem to be off, many devices continue to draw power, impacting both our consumption and the environment. In this article, we’ll explore what standby is, how much it affects your bill, and how to eliminate waste with simple tips, like turning off appliances or using  power strips with switches.

What Is Standby and How Does It Work

Standby, or “sleep mode,” is a state where an appliance seems to be off but is actually ready to reactivate quickly. This means some components remain active, consuming energy. Think of your TV: even when turned off with the remote, the little red light stays on, indicating it’s in standby and ready to receive the signal to turn on.

Which appliances consume power in standby? Virtually all those with a display, a receiver, or a timer, such as:

  • Televisions
  • Decoders/Set-top boxes
  • DVD/Blu-ray players
  • Microwave ovens
  • Computers
  • Monitors
  • Printers
  • Video game consoles
  • Hi-Fi systems

How Much Power Do Appliances Consume in Standby?

Standby power consumption varies depending on the type of appliance, its model, and its age. In general, it’s estimated that each device consumes 1 to 4 watts per hour in standby. This may not seem like much, but when multiplied by the number of appliances in your home and the hours they remain unused, the consumption becomes significant.

According to ENEA (the Italian National Agency for New Technologies, Energy and Sustainable Economic Development), the average annual standby consumption for a household can reach 100 kWh, with a cost on the bill that can exceed $50.

To give you a clearer idea, here is a table with the average standby consumption of some appliances:

ApplianceAverage standby consumption (watts/hour)
Television2-3
Decoder/Set-top box1-2
Computer2-5
Monitor1-2
Microwave oven2-3
Printer1-3

How to Eliminate Standby Power Consumption

There are several solutions to eliminate or reduce standby power consumption:

  • Turn off appliances completely:  The most effective way is to turn off devices using their power button or, even better, unplug them when not in use for long periods.
  • Use power strips with switches: Power strips with switches allow you to cut power to multiple devices at once with a single flick. They are especially useful for devices connected to your TV (decoder, console, DVD player) or for your Hi-Fi system.
  • Unplug them: For appliances we don’t use frequently, like the microwave or printer, unplugging them is the most drastic but also the most effective solution.
  • Set up power-saving options: Many modern devices, like computers and TVs, offer power-saving options that allow you to reduce standby consumption or automatically turn the device off after a period of inactivity.

Benefits of Eliminating Standby Power

Eliminating standby power consumption offers numerous benefits:

  • Financial savings: Reducing standby power translates to direct savings on your utility bill.
  • Reduced environmental impact: Less consumption means fewer CO2 emissions and a smaller environmental footprint.
  • Greater home safety:  Unplugging appliances when not in use reduces the risk of fires or short circuits.
  • Longer appliance lifespan:  Avoiding component overheating helps extend the life of your devices.

Power Strips with Switches: Types and Features

There are several types of power strips with switches on the market:

  • Standard power strips: These are the simplest and most affordable, equipped with a master switch to turn all connected devices on or off.
  • Surge protectors:  They protect your devices from potential power surges, preventing damage to electronic components.
  • Timer power strips: They allow you to schedule the automatic turning on and off of connected devices.
  • “Smart” power strips: Controllable remotely via smartphone or voice assistants, they let you manage power to your appliances even from a distance.

When choosing a power strip, it’s important to consider the number of outlets needed, the cord length, the presence of additional protections, and the type of switch.

Other Tips for Saving Energy at Home

Besides eliminating standby power, there are other steps we can take to reduce energy consumption at home:

  • Choose high-efficiency appliances:  Opting for ENERGY STAR certified appliances ensures lower consumption during use.
  • Use LED bulbs: LED bulbs consume up to 80% less energy than traditional incandescent bulbs.
  • Optimize appliance use:  Running the washing machine and dishwasher with full loads, avoiding opening the oven while cooking, and regularly defrosting the refrigerator are just a few examples of good practices for saving energy.
  • Insulate your home:  Improving the thermal insulation of walls, windows, and the roof helps reduce heat loss, thus lowering heating and cooling costs.

Conclusion

Reducing standby power consumption is a small act that can make a big difference, both for our wallets and for the environment.  Turning off appliances when not in use, using power strips with switches, and adopting mindful energy consumption habits are simple yet effective actions to contribute to a more sustainable future.
