Smartphones, laptops, tablets, digital TV. You may not have considered it, but all those devices require a lot of energy to operate, and gobble it up even when they sit idle.
In fact, the iPhone uses more electricity than a refrigerator. A medium-sized, energy star fridge uses 322 kilowatts an hour each year. The average iPhone? 361.
That includes the WiFi connection, data usage and battery charging, according to a new study by the Digital Power Group.
But it's not just smartphones. Add up all the new technology we have, and they use about 10 percent of the world's energy pie.
To put that another way: All the new technology together uses 50 percent more energy than global aviation uses.
And analysts say our need for electricity will just keep growing. Because who knows how many devices or even what types of devices we'll have in 20 years. And we keep them on all the time.
Think about it. Lights and air conditioning you turn off, but not your phone or DVR box.
