Apple iPad owners out there, do you know that it will cost only $1.36 a year to charge your favorite slate? Surprised? This has been revealed in a study conducted by the Electric Power Research Institute (EPRI) on the assumption that a user fully charges his iPad every other day.
The figure implies that an iPad consumes 12 kWh of electricity a year. This would mean that across the world, 590 gigawatt hours of energy is used to charge 67 million iPads already sold. It is estimated this number will triple in the next two years. Then the energy required to power the devices would equal two 250-megawatt power plants operating at 50 percent utilization.
EPRI’s study points out that though they consume power, more people are using such devices for various purposes like gaming, video consumption, and Web browsing. This, in turn, will effectively reduces the power load of higher-consuming products.
Mark McGranaghan, vice president of power delivery and utilization at EPRI opined that now the concern is about how the shifting reliance from desktop to laptop to mobile devices will change energy use and electricity requirements.
Well, what do you think? Will switching to slates be of any help?
