Reply #25: As a 30 year electronics engineering tech, the losses/ savings estimate appears valid...... [View All]

those low voltage wall transformers kept plugged in all week for use for only 10 mins a week are hysteresis losses in the primary side, do they feel warm to the touch when the device is turned off, that is a energy loss in the off mode.

the low voltage power supply to keep the clock or display or remote control receiver in the microwave or vcr or programmable coffee maker etc. going could be considered a loss

the % of loss will vary with usage factors, the vcr I use once a year may approach the 25% loss number
