How To Make Your Monitor Eco Friendly.
Monitor is our “eyes” when we work with computer. Everything we typed or instructed, are viewed in the monitor. Millions of eyes around the world fix on the monitors for hours everyday, and unfortunately, it is the most energy-consuming part of a computer. It takes 2/3 of the electricity used on operating a computer set. Therefore efficiency in the monitor operation will help creating eco friendly computing. Here are some facts about the electricity consumption and the environmental impacts for your consideration in using your monitor.
Kinds of monitors and each benefits.
CRT (Cathode Ray Tube ) Monitors:
This is the traditional type of monitor that generate their own light by using their cathode rays. This type of monitor consumes more power than the newer type, LCD monitor. CRT monitors also contain substantial concentration of lead and phosphors, that The U.S. Environmental Protection Agency ( EPA) categorized the discarded CRT monitors as “ hazardous household waste”. Because of its shape, it takes more space in your desk whilst generates more heat when running. So if you still use this type of monitor, think of replacing it with a newer type, which is more eco friendly.
LCD ( Liquid Crystal Display ) Monitor :
This is the newer type of monitor that uses LCD panel. LCD monitors have several advantages over the CRT monitors :
Consume less energy ( according to the US EPA , the energy efficiency can be up to 66% ) The screen present lower intensity and constant light pattern that are friendlier to our eyes Smaller in size and weight. Generate less heat
Kinds of LCD monitors :
There are 2 kinds of LCD monitor, differs from the light source used as backlight of their display :
LCD monitors that use Cold-Cathode Fluorescent (CCF ) Bulb :
As mentioned above, LCD monitor is more eco friendly compared to the CRT type, yet their CCF bulb contain some amount of mercury.
LCD Monitor that uses Light Emitting Diodes (LED) Bulb:
This is the newest type of monitor with LCD technology which uses light emitting diodes ( LED) as backlight. Using LED lighting, this monitor consumes even lower energy than his cousin that using CCF bulb ( in some type, 40% lower energy consumption ); and it does not either contain mercury. So this LED type monitor become more eco friendly than of the one with CCF backlight . Another advantage LED based monitor presents a better display, with higher resolution and color accuracy.
So of the all the 3 kinds of available monitors, LED based monitor is the most eco friendly monitor which also can save you significant electricity consumption.
Tips to Make Your Monitor Eco Friendly.
Some other tips to save electricity consumption when computing is by setting your monitor efficiently, with following tips :
- Choose low- energy monitor, be sure to have products with Energy Star label, or one that meet Energy Star qualification. On average, monitors that have earned the ENERGY STAR are 20% more energy efficient than standard options.
If all displays sold in the U.S. were ENERGY STAR qualified, the energy savings would grow to about $1 billion each year and prevent greenhouse gas emissions equivalent to those from nearly 1.5 million vehicles.
- Consider using a smaller monitor. Smaller display consumes less energy, for example, a 14” monitor requires 40% electricity than a 17” one.
- Reduce the brightness on your monitor. The brighter the display, the more energy it consumes.
If you decide to go for a greener monitor, do not just throw away the old one . EPA estimates that 31.9 millions computer monitors - both flat panel and CRTs - were discarded in 2007. Imagine the pollution and emission they might generate if not properly discharged. Your old monitor too, might contain hazardous and toxic substance. Help our Earth, donate or recycle it.
