“The growing number of devices in our daily lives means that we are consuming more and more electricity. This is something that worries lots of people, including me. A new study from a Palo Alto-based not-for-profit group takes a look at thte iPad’s energy consumption habits.”
We do not share the worries as expressed by the article, linked to below, at all! Every hour spent with an iPad is not spent in a car or behind a television or a laptop/desktop computer, all vastly outconsuming the little synmpathetic device as far as power is concerned. Consider that an iPad can replace a desktop, laptop, TV and yes even a car (e-shopping) then it becomes clear what a central role devices like these could play in a resource depleted society. The article assumes a yearly energy consumption of 12 kwh, costing $1,36 against current prices. Even this tiny amount is probably exagerated. Assuming a power consumption of 4 Watt and heavy daily use of 4 hours, this would mean a yearly power consumption of 4 * 4 * 365 = 5.8 kwh.
