Dark mode, or dark mode, has become increasingly popular in recent years, and not only for a matter of style. According to a study conducted in 2021 by Purdue Universitythis function, when used on devices with a screen OLEDcan lead to considerable energy savingsthus contributing to the reduction of the environmental impact. In this article we will analyze the results of this research and see how the adoption of Dark Mode can be a small but significant step towards a more sustainable future.
Dark mode and drums: how much do you really save?
The use of dark mode has now spread on smartphones, computers and applications. But its impact on the battery life It is the most studied benefit. According to data collected by Purdue University, savings varies according to the brightness of the device:
- With brightness between 30% and 50%energy saving stands between the 3% and 9%.
- By increasing the brightness up to 100%savings can go up to 39-47%.
These results confirm that The use of dark mode becomes particularly effective with high brightnesswhile with low brightness the difference in consumption is less evident.
Why do the OLED screens benefit from Dark Mode?
To better understand the energy saving of the dark modeit is essential to consider the type of device screen. OLED screensunlike the LCD ones, they emit light only from active pixels. This means that when black is displayed, pixels come offspringdrastically reducing energy consumption.
The latest generation smartphones are often equipped with OLED screensand therefore the savings potential is greater than the devices with LCD displayin which the backlight remains constant regardless of the colors shown on the screen.
The initiative of Invisiblefarm to promote the use of the dark mode between one’s team shows how even small changes in digital habits can contribute to sustainability.
Reduce the energy consumption of devices, even if only a few percentage points, can have a positive environmental impactsince it lowers the demand for electricity, often generated by fossil fuels and other non -renewable sources. Consequentially, Carbon emissions are reduced And we can contribute to contrasting climate change.
Small changes make the difference
The adoption of the dark mode It is a simple but effective way for save energy and reduce the environmental impact. Although savings may seem minimal, every conscious choice in the use of technology can lead to concrete benefits. The Invisiblefarm initiative is an example of how the simpler daily actions can contribute to a more sustainable future.
In an era in which technology is an integral part of daily life, Every small decision matters. Choose the dark mode It is not only a question of visual style or comfort, but an option that can make the difference for both the autonomy of the device that for the environment.
