Small Changes In Your Daily Life Can Generate Great Energy Savings. Find Out How To Reduce Your Electricity Bill.
Even when turned off, Smart TVs and other electronics in our homes continue to consume electricity in standby mode. This invisible consumption can represent a significant part of the electricity bill at the end of the month, right? We will see tips to save energy.
According to the information released on the SEBRAE website, the sum of all appliances in standby in a household can represent up to 12% of the total consumption of electricity.
Considering an average of R$ 150 per month spent on the electricity bill, the cost without the consumption of appliances in standby could make the bill R$ 18 cheaper every month. In other words, an electricity bill with this value could have a discount of up to R$ 216 over 12 months.

What Are The Main Villains Of Electricity Consumption In Standby Mode?
Smart TVs are some of the main culprits for energy consumption in standby mode. Even when turned off, these televisions continue to consume electricity to keep certain functions active. Among these functionalities are:
- Internet connectivity for automatic software updates and app downloads;
- Quick activation capability through remote commands;
- Voice command detection from virtual assistants like Alexa and Google Assistant;
- Connection to other devices, such as game consoles and media players.
In addition to Smart TVs, there are other electronic devices that contribute to increased energy consumption even when not in use. Among the main villains of electricity consumption in standby, we can highlight:
- Sound systems: audio equipment often stays in 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 energy consumption;
- Cell phone chargers: even without the device connected, the charger continues to consume power;
- Desktop and notebook computers: desktops and laptops, when not completely turned off, consume energy in sleep mode;
- Video game consoles: current consoles remain connected to the internet for automatic updates and background downloads;
- Cable TV decoders: remain powered on even when the TV is turned off;
- Cooktops and ovens: many of these appliances have digital clocks and timers that constantly consume power;
- Microwaves: have digital clocks and standby lights that consume energy continuously;
- Wi-Fi routers: remain on all the time to keep the internet connection active;
- Wireless phones: charging bases consume power even when the device is fully charged.
How Much Does Each Electronic Device Consume In Standby?
Energy consumption in standby varies according to the type of device and its features. On average, these devices 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 year. A cell phone charger plugged into the outlet, even without the phone plugged in, can consume approximately 4.5 watts per hour.
If we consider continuous use, this consumption can represent a considerable impact on the electricity bill throughout the year.
Other examples of standby consumption include:
- A Wi-Fi router can consume between 5 and 10 watts per hour;
- TV decoders can consume between 10 and 20 watts per hour;
- Video game consoles can consume up to 50 watts per hour if not completely turned off.
How To Identify Electronics In Standby And Save Energy
To identify if a device is consuming energy in standby, just look for the presence of indicator lights on the device, such as LEDs in green, red, or blue. Additionally, digital clocks and lit displays are indicative 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, it indicates that energy consumption is occurring, even when not in use.
How To Save Energy – Up To R$ 216 Per Year On Your Electricity Bill
To avoid unnecessary energy consumption at home, it is important to adopt some simple practices, such as:
Unplugging devices: whenever possible, unplug electronics that are not in use;
Using power strips with switches: these devices allow you to turn off multiple appliances at once, facilitating consumption control;
Setting appliances to energy-saving mode: many devices have specific settings to reduce standby consumption;
Investing in LED bulbs: besides consuming less energy, they have a longer lifespan;
Using smart plugs: these smart plugs allow remote control of devices and cut the power supply when not in use.
Additional Tips To Reduce Your Electricity Bill
In addition to avoiding unnecessary consumption of electronics in standby, there are other strategies to reduce your electricity bill:
Installing curtains and blinds: help keep the environment cooler and reduce the need for air conditioning;
Adopting a solar heating system: reduces dependence on the electric shower, which is one of the biggest villains of the electricity bill;
Replacing old appliances with Procel A-rated models: these appliances ensure greater energy efficiency;
Avoiding the use of appliances during peak hours: hours between 6 PM and 9 PM usually have higher tariffs;
Preventive maintenance of appliances: poorly regulated devices can consume more energy than necessary;
Educating residents: teaching family members about good practices for savings can make a significant difference in the final bill.
The Act Of Saving Energy
The act of saving electrical energy at home is possible with small changes in habits and investments in efficient equipment.
By avoiding unnecessary consumption of electronics in standby, adjusting the timings of household appliance use, and adopting smart solutions like power strips and smart plugs, it is possible to significantly reduce electricity expenses.
