As reported in Energy Manager Today smartphone sales volumes in 2012 were estimated at 717 million retail shipments worldwide. This represents a 45 percent increase from 2011.
Smartphones are increasingly being used to do the things that used to be done on computers, televisions, and game consoles. Unlike computers, televisions and game consoles, smartphones require far less energy compared to these other electronic devices.
A study from Opower, Outlier’s parent company, the cost to charge an iPhone 5 is just $0.41 per year, and charging the Droid Galaxy SIII costs just $0.53.
Smartphones require a tiny fraction of the energy used by a PC or a TV. The Opower report indicates that a PC's energy usage is 20 times greater than a smartphone and the yearly electricity costs of a plasma TV is 100 times greater.
To generate these statistics Opower used energy data from 50 million homes and 75 utility partners. This data was cross-referenced with weather and demographic information to produce their analyses.
