That coffee you’re drinking while gazing at your iPad? It cost more than all the electricity needed to run those games, emails, videos and news stories for a year.
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.
…assumed that users would charge up every other day.
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 year: just 38 cents.
