The world’s 14 billion television decoders, printers, game consoles and other electronic devices waste $80 billion (R851bn) of power a year due to inefficient standby technology, according to the International Energy Agency. “Electricity demand of our increasingly digital economies is growing at an alarming rate,” the organisation said yesterday. By 2020, $120bn would be wasted annually. Networked devices globally used about 616 terawatt-hours of power last year, it said. Of that, 400 TWh was wasted. “Such devices could perform exactly the same tasks in standby while consuming 65 percent less power.” – Bloomberg
