What are the main causes of electricity consumption in standby mode?
Smart TVs are one of the main culprits of energy consumption in standby mode. Even when turned off, these televisions continue to consume electricity to keep certain functions active. Among these features, the following stand out:
- Internet connectivity for automatic software updates and application downloads;
- Ability to quickly activate via remote commands;
- Detection of voice commands from virtual assistants such as Alexa and Google Assistant;
- Connection to other devices such as video game consoles and media players.
In addition to Smart TVs, there are other electronic devices that contribute to increased energy consumption even when they are not being used. Among the main culprits of standby electricity consumption, we can highlight:
- Sound equipment: audio equipment often remains on standby to respond quickly to remote commands;
- Virtual Assistants: devices like Alexa, Google Nest and Home Pod require constant power to always be ready to respond to voice commands;
- Coffee makers: many modern models have programmable functions that require continuous power consumption;
- Cell phone chargers: even without the device connected, the charger continues to consume energy;
- Desktop and notebook computers: desktops and laptops, when not completely turned off, consume power in sleep mode;
- Video game consoles: Current consoles remain connected to the internet for automatic updates and background downloads;
- Cable TV Set-Top Boxes: remain on even when the TV is turned off;
- Cooktop stoves and ovens: many of these appliances have digital clocks and timers that constantly consume energy;
- Microwave: have digital clocks and standby lights that consume energy continuously;
- Wi-Fi Routers: remain connected at all times to keep the internet connection active;
- Cordless phones: Charging docks consume power even when the device is fully charged.
How much does each electronic device consume on standby?
Standby power consumption varies depending on the type of appliance and its features. On average, these appliances can consume between 1 and 50 watts per hour, depending on their specifications and active functions.
For example, a modern Smart TV can consume up to 2 watts per hour when turned off, which represents about 17,5 kWh over the course of a year. A mobile phone charger plugged into a wall outlet, even without the phone plugged in, can consume approximately 4,5 watts per hour.
If we consider continuous use, this consumption can have a considerable impact on the electricity bill throughout the year.
Other examples of standby consumption include:
- A Wi-Fi router can consume 5 to 10 watts per hour;
- TV set-top boxes can consume 10 to 20 watts per hour;
- Video game consoles can consume up to 50 watts per hour if they are not turned off completely.
How to identify electronics on standby and save energy
To identify whether a device is consuming energy in standby mode, simply look for indicator lights on the device, such as green, red or blue LEDs. In addition, digital clocks and displays that are lit up are indicators that the device is in standby mode.
Another tip is to check the temperature of chargers and devices. If they are warm to the touch, this indicates that they are consuming energy, even when they are not in use.
