The report, More Data, Less Energy: Making Network Standby More Efficient in Billions of Connected Devices, shows that electricity demand of our increasingly digital economies is growing at an alarming rate. While data centre energy demand has received much attention, of greater cause for concern is the growing energy demand of billions of networked devices. In 2013, a relatively small portion of the world’s population relied on these devices to stay connected. But energy demand is increasing as a growing share of the world’s population becomes wired and as network connectivity spreads to devices and appliances that were previously not connected, such as washing machines, refrigerators, lights and thermostats.
