Apple's iPad costs precious little for you to charge it each year, according to a new study.

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.

The EPRI assumed that there are now 67 million iPads in the world and applied the average energy use to each device to arrive at a total of 590 gigawatt hours of overall usage. In the event the number of iPads worldwide triples over the next two years, the energy required to power the devices would equal two 250-megawatt power plants operating at 50 percent utilization, according to EPRI. A quadrupling in sales would require three plants.
