How much does it cost to charge an iPad for a year?

NEW YORK — 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.

The group, known as EPRI, studied the power consumption of Apple Inc.’s iPad to determine the effect that the newly-popular devices might have on the nation’s electricity use.

The answer: not much.
If the number of iPads triples from the current 67 million, they would need the electricity from one small power plant operating at full strength.

But if people are using iPads instead of televisions to play video games, or ditching their desktop computers for iPads, the shift to tablets could mean lower overall power consumption.

A desktop computer uses 20 times more power than an iPad.
