These are worldwide figures. 750 million each of desktop and laptop computers, 1 billion smart phones, 100 million each of servers and WiFi/LAN, 50 million Cloud. Worldwide power supply is ~5,000 GW. This suggests the internet used 3-6% of grid power in 2010. Their analysis assumes that desktops are switched on 1/2 the time and laptops 3/4, while 1/2 their on-time is devoted to internet use. Embodied power is energy required to make a device, divided by its lifetime. Devices are replaced.
