The annual cost to charge an iPad is just $1.36, according to the
Electric Power Research Institute, a non-profit research and
development group funded by electric utilities. By comparison, a
60-watt compact fluorescent bulb costs $1.61, a desktop PC adds up
to $28.21 and a refrigerator runs you $65.72.
But there’s an even cheaper way to go than the iPad. EPRI
calculated the cost of power needed to fuel an iPhone 4 for a year:
just 38 cents.
If The New York Times had run this story, the headline would have been, “iPads Cost Four Times More to Charge Than iPhones”.
