New approach to reducing standby power

摘要

US electricity usage is more than double what it was back in the mid 1970s, according to the Energy Information Administration. However, usage has started to plateau in recent years due to increasing awareness of energy efficiency and more stringent government regulations. One of the key areas where progress has been made is in trying to reduce the electricity consumed by the multitude of different power supplies found throughout the home for powering consumer electronic devices. In the past, the focus has been on improving active mode efficiency of the power supply. Now, many power supply manufacturers are taking notice of the energy consumed in standby mode.
