The Challenge: Lower your computer monitor’s brightness to a comfortable level to conserve energy.
This simple action supports Sustainable Development Goal (SDG) 12: Responsible Consumption and Production, which encourages efficient use of resources and energy. By adjusting your monitor’s brightness, you can reduce electricity consumption and extend the lifespan of your device.
Why It Matters
Computer monitors can be significant energy consumers, especially when set to high brightness levels. Reducing brightness not only conserves energy but also lessens eye strain, promoting better health and productivity.
- A typical LCD monitor consumes about 20-30 watts per hour at full brightness.
- Lowering brightness by 30% can reduce energy consumption by up to 20%, depending on the monitor.
- Over time, this small adjustment can lead to noticeable energy savings, especially in environments with multiple monitors.
One Small Action You Can Take
- Access your computer’s display settings.
- Reduce the brightness to the lowest comfortable level for your eyes.
- Consider enabling automatic brightness adjustment features, if available, to optimize energy use based on ambient light.
Caution and Considerations
- Ensure that the brightness level remains sufficient to prevent eye strain.
- In well-lit environments, too low brightness may cause difficulty in viewing the screen; adjust accordingly.
Take the Challenge
Today, take a moment to adjust your monitor’s brightness. This minor tweak contributes to energy conservation and supports the goals of SDG 12 by promoting responsible consumption of electronic resources.
