How Much Electricity Do iPads Consume?

How much electricity do the worlds iPads consume? The Electric Power Research Institute (EPRI) came up with these intriguing statistics and comparisons.

The EPRI reports:

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

...each model of the iPad consumes less than 12 kWh of elelctricity 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.

...the average energy used by all iPads in the market is approximately 590 gigawatt hours (GWh). In a scenario where the number of iPads tripled over the next two years, the energy required would be nearly equivalent to two 250-megawatt (MW) power plants operating at a 50 percent utilization rate. A quadrupling of sales in two years would require energy generated by three 250-MW power plants. iPads will consume about 65 percent more electricity per year. What remains to be seen is how better batteries, better features and changing preferences will affect overall energy consumption by consumers as a whole.

...the Apple iPhone 3G consumes 2.2 kWh of electricity each year, which results in a power cost of $.25 annually.

Other products that were included in the analysis were laptop PCs, which consume 72.3 kWh of electricity each year and cost consumers $8.31...

The television cited consumes a lot more energy than a tablet, or even a computer monitor, because TVs are bigger and brighter for viewing by multiple people at a greater distance.
