Those who may be a bit nervous about spending or using too much energy with their iPad and iPad accessories should take a look at a recent report from the Electric Power Research Institute. This report said charging a new iPad only costs about $1.36 per year, a meager offering compared with charging a desktop or a laptop.
Each model of the iPad uses less than 12 kilowatt hours of electricity per year, which is much less than a plasma 42-inch television which will consume 358 kWh of electricity per year, the EPRI report said. The average energy used by all iPads on the market, of which Apple said there is 67 million, is 590 gigawatt hours.
“As information technologies continue to change rapidly we see important implications for energy consumption,” said Mark McGranaghan, vice president of Power Delivery and Utilization at EPRI. “These results raise important questions about how the shifting reliance from desktop to laptop to mobile devices will change energy use and electricity requirements for the information age. At less than a penny per charge these findings bring new meaning to the adage, ‘A penny for your thoughts.’”
Those debating a laptop versus a tablet and iPad accessories should note that the EPRI report said laptops take up 72.3 kWh of electricity each year and cost $8.31.
