Indeed, it's very easy to oversimplify. The combination of use patterns, utility and power consumption during standby must be considered. Computers are a case in point, in order to be power efficient they need to consume some standby power, in good systems the standby power is now in the order of 1W for off and 2W for standby (instant on). The fact is that people will be happier to set their power saving functionality to power down the system over a shorter period of non-activity if the unit will spring back into action at the touch of the keyboard or power button. I know I will hit the power button now when I walk away from my computer knowing that it will take mere seconds to reactivate. This type of system functionality and user behaviour will generally promote net savings in energy use over a day, so the standby power is worth the expenditure. Everyone should have or have access to a precision power meter so that they can analysis the power consumption of all their electrical equipment. Some items are surprisingly efficient others are woeful but without a proper means of assessment it's all a big guess. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
