If your trying to lower your monthly bill for electricity, make sure your iPad isn’t the first piece of technology you remove from the power outlet. Even with the large battery used to power the retina display the iPad still manages to use less power than the average light bulb yearly. This is based off an iPad charging every other day from its discharge state.
This information comes inclusively from the Electric Power Research Institute, who completed research finding Apples iPad could help lower the high power consumption experienced these days. Even with an every other day charge cycle the average cost is $1.36 per year for all the iPads charge cycles.
The third generation iPads 42.5-watt-hour battery was found to use less than 11.86 kilowatt hours of electricity per year. An HD 42″ Television itself uses 358 kWh, and it probably runs nearly around the same amount of time as an iPad charging. The only closest comparison to the iPad is a light bulb, using up an average of 14 kWh per year.
With that said, a tablet and phone are probably the most energy efficient products in your house. If you’re interested in saving money than try unplugging large products such as your television when they aren’t in use.
If you had to guess, what would you think an iPad would’ve costed to charge?
