Pretty interesting finding. If this is really the case then I’m using well less than half this amount as I only charge my iPad on the order of about once a week. iPhone? Different story. Wonder how much that uses.
The Electric Power Research Institute (EPRI) conducted a study recently to see how much the iPad costs in electricity if users fully charge it every other day. The research agency, which is funded by electric power companies, found that the iPad will cost owners $1.36 a year, thanks to its consumption of just 12 kWh of electricity each year.
