A NEW REPORT has shown that an Apple iPhone uses more energy in a year than a refrigerator. An average iPhone uses about 361 kilowatt-hours each year after factoring wireless connection, data usage and battery charging. While a medium-sized refrigerator with an energy star rating only uses about 322 KWH a year.
According to the report,the world's communication system use 1,500 terawatt hours - 10% of global energy and as much as Germany and Japan combined.Only one terawatt hour is enough to power roughly 90,0000 homes for a year.
Mobile internet and cloud computing require more energy than wired networks. BY 2035, only slightly less energy will be needed to power the cloud than for lights,the report estimated.
