This analysis is not correct, since the amount lost in wiring is generally a fraction of that used by the equipment itself. For example:In this webpage http://www.faqs.org/faqs/electrical-wiring/part2/section-11.htmlit says that '110 V loses 4 times more power in the house wiring than a 220V motor', so all those devices like fans, blenders (kitchen mixers), vacuum cleaner, driers consume 4 times more power and increases the bill unnecessarily for the consumer.
If a 110 V motor that uses 100 watts loses 2 watts in wiring (total 102 watts), where a 220 V motor would lose 1/2 watt (total 100.5 watts), the 110 V motor is only using about 1% more power, not four times more power.
