Charging your iPad Costs US$1.36 Per Year
Have you ever wondered how much does it cost you every year to keep the third generation Apple iPad charged up? Well, the Electric Power Research Institute (EPRI) conducted a study recently and shows that you only need to fork out an average of US$1.36, which is lower than a 60-watt compact fluorescent lightbulb (not kept on all the time) that will cost you US$1.61.
Besides the iPad, the study also included other electronic devices in the house. Not surprisingly, the refrigerator is the most expensive item on the list which will set you back about US$65.72 per year. The average desktop PC consumes 20 times more power than the iPad at US$28.21. The study claims that if the number of iPads triples from the current 67 million, all we need is one small power plant operating at full capacity to supply sufficient power for each of the tablet to be charged up whenever necessary.
The study also states another interesting finding - if tablets are to replace notebooks and tablets in the near future, there is high possibility that there will be a sharp decline in power consumption. What about the Apple iPhone 4? You only need US$0.38 to keep it charged up.
While it is good to know that the new iPad doesn't cost you a bomb in keeping it charged up, it doesn't change the fact that you need an estimated five hours to fuel up the large 11,560mAh battery.
