As you know personal computers use a lot of power. In fact, with their printers and monitors, computers in the USA use each year as much electricity as the whole state of Oregon. Not to waste electricity, new ‘green’ computers are being developed by more than a hundred personal computer firms in the USA. When left on but unused for more than a few minutes, they go down to a standby, using 80 per cent less energy. At a command the PCs return to full power.
