Fujitsu Siemens has successfully come up with monitors that don't consume electricity from the main electrical supply when in standby mode. The technology is covered by six patents, and the first of these monitors are scheduled to go on sale next spring.
How do these monitors work? They use capacitors to store enough of a charge to flick it back on when the signal returns. The presence of solar panels also provide enough power to maintain this mode for up to five days. Beyond that, a regular power button can be used to bring the monitor out of standby.
Fujitsu Siemens showed two 22in widescreen test monitors with power meters attached at a press event in Augsburg, Germany. The display drew 0.6-0.9W when the monitor was switched off using its standby button and with an active video signal from a VGA cable present. When the display signal was switched off, the monitor drew zero power even though the standby/power button was not pressed.
This technology appears to come in handy when you consider estimates by the British Government that up to eight percent of all domestic electricity is consumed by devices in standby.
