It is important to note that the average power consumption in the un-developed world is under 400 watts of power or 3,471 kW-hours per year per household. Only in Europe, Australia, Middle East and North America do households consume more power than the world average. North America (USA) averaged home electricity use is approximately 2.5 kilowatts per hour X each 24 hour period (22,000 kilowatt hours per averaged household per year)
