It turns out that it takes less energy to display the color black than it does to display other colors. The U.S. Department of Energy published its findings that monitors can consume up to 20% more power when they display white colors than when they display darker colors. Check out their findings here.
Is this true for all monitors? The power savings are more dramatic for CRT (cathode ray tube) monitors, ranging between 7 and 15 watts in savings depending on the size and model. LCDs, on the other hand, have mixed results. LCD screens employ a background light that remains on regardless of the color displayed. Some manufacturers have built intelligence into their displays that dim the light when the monitor primarily displays dark colors, which results in some small energy savings when a black background is used, however there are mixed studies on how effective this really is.
At Greenback Search, we believe that every small effort counts, which is why we've chosen to offer an eco-friendly color choice for whatever style of monitor you use. However, we don't stop there. When you use Greenback Search, you get the same Google search results, but we purchase carbon offsets on your behalf to help offset your carbon footprint. What could be easier? Learn more here
