Roughly $80 Billion Wasted on Power for Networked Devices, Report Says

The world’s 14 billion online electronic devices, such as modems, printers, game consoles, and cable boxes, waste around $80 billion in electricity annually because of inefficient technology, according to a new reportby

the International Energy Agency (IEA). In 2013, networked devices consumed around 616 terawatt hours (TWh) of electricity, with most of that used in standby mode. Roughly 400 TWh — equivalent to the combined annual electricity consumption of the United Kingdom and Norway — was wasted because of inefficient technology. The problem will worsen by 2020, the agency projects, with an estimated $120 billion wasted as devices such as refrigerators, washing machines, and thermostats become networked. Much of the problem boils down to inefficient “network standby,” or maintaining a network connection while in standby mode. Most network-enabled devices draw as much power in this mode as when fully active, the report notes. Using today’s best technology could cut energy consumption by 65 percent, the IEA said.
