It Costs Less to Charge an iPad Annually Compared to a CFL Light Bulb [Report]

by on June 22nd, 2012

According to a report by the Electric Power Research Institute (EPRI), an independent nonprofit organization, their tests have revealed Apple’s iPad only costs consumers $1.36 to charge every year, for those that charge it every other day:

Consumers who fully charge their iPad tablet every other day can expect to pay $1.36 for the electricity needed annually to power the device, according to an assessment by the Electric Power Research Institute (EPRI).

The analysis shows that each model of the iPad consumes less than 12 kWh of [electricity] over the course of a year, based on a full charge every other day. By comparison, a plasma 42” television consumes 358 kWh of electricity a year.
year.

The EPRI conducted the tests at their labs in Knoxville, Tennessee. Of course, costs may vary depending on the price of electricity in your location. Here are other results from their charge/cost tests:

- Apple iPhone 3G consumes 2.2 kWh yearly; $.25 annual cost
- Laptop PCs consume 72.3 kWh yearly; $8.31 annual cost
- 60W CFL light bulb consumes 14kWh yearly; $1.61 annual cost

Interesting results, nonetheless, even though they were only conducted in the a specific part of the USA. It would be interesting to know what these numbers would be in Canada (anyone out there want to do the tests?!). How often do you charge your iPad?

    Since you know how much kWh it consumes over a year all you need to know is how much you are paying for electricity in your city to calculate the cost. The only there is no need to reproduce the test if they measured the amount of electricity used correctly.
