A new study shows the charging costs for various computing devices including the iPhone 5, iPhone 4S, Samsung Galaxy S III, and iPads. When compared to traditional laptops and desktops, mobile computing has significant energy cost savings year to year.
The collective annual electricity consumption of the iPhone 5’s sold within 12 months will be equivalent to the annual electricity usage of 54,000 US households (roughly equivalent to the size of Cedar Rapids – the second largest city in Iowa). That’s just for one smartphone model over one year.
When you consider the sharp rise of the smartphone and tablet industry compared to the bitter decline of the overall PC industry, energy cost savings are a nice little byproduct. Check out the entire report on Outlier (opower.com).
