Computers and other electronic devices are part of daily life. Although the consumption of each appliance can be relatively small, hours of use and the number of connected devices influence the total electricity bill.
With some adjustments you can reduce consumption without giving up the functions you need.
1. Activate power saving mode
Configure the computer to turn off the screen and go to sleep after a reasonable period of inactivity.
In Windows, macOS and other systems there are power options that allow you to adapt the equipment’s behavior to your habits.
2. Adjust the monitor brightness
A screen with brightness higher than necessary can consume more electricity, depending on the technology and model.
Reduce the brightness to a comfortable level for the room’s lighting. If you work many hours, also look for a configuration that avoids glare and visual fatigue.
3. Turn off equipment you do not need
If you are not going to use the computer for a prolonged period, you can turn it off instead of keeping it on unnecessarily.
The best option depends on your needs, the inactivity time and the tasks the equipment must perform.
4. Check the consumption of peripherals
Additional monitors, speakers, printers and other accessories also use electricity.
Turn off the ones you do not need and check if some can be disconnected when not in use, always following the manufacturer’s instructions.
5. Do not forget standby consumption
Some devices continue consuming energy when they remain connected even though they are not operating actively.
You can use a power strip with a switch to disconnect several compatible devices, but do not use it with appliances that must remain on or with loads that exceed its capacity.
6. Check if it is worth replacing a device
A newer computer does not always consume less in every situation. The expense depends on the processor, graphics card, screen, peripherals and workload.
Before buying new equipment, check the consumption of the current one and calculate how long it would take to recover the investment.
7. Calculate consumption easily
You can estimate the energy used with this formula:
Consumption in kWh = power in kW × hours of use
For example, a device that consumes 100 W for five hours would use, approximately, 0.5 kWh in that period if its power remains constant.
Real consumption can vary according to equipment activity. To measure it, you can use a compatible and safe energy meter.
8. Do not disconnect the router without assessing its functions
The router usually stays on to provide internet connection and allow other devices to work.
Turning it off when not needed can reduce its consumption, but it can also interrupt cameras, security systems, telephony or home automation. Assess which services depend on it before doing so.
The computer and the router are part of the home’s electricity consumption. To better understand what you pay on each bill, consult our guide on how to read your electricity bill and understand what you are paying.

Conclusion
Start by activating automatic sleep, adjusting brightness and turning off devices you do not use. They are simple changes that can reduce consumption without needing to replace equipment.
