Internet Uses 9.4% of U.S. Electricity, According to Uclue Research
September 27, 2007 (PRLEAP.COM) Technology NewsEquipment powering the internet accounts for 9.4% of electricity demand in the U.S., and 5.3% of global demand, according to new research from Uclue.com.
The annual energy demand of computers, monitors, networking, and transmission equipment for the internet amount to 350 billion kWh in the US — 9.4% of the 3.7 trillion kWh used in total. Similarly, world demand for the internet is 868 billion kWh, or 5.3% of total global electricity consumption of 16.33 trillion kWh.
The largest demand for internet-related energy use comes from desktop computers and monitors, which account for two-thirds of total use. Networking equipment such as modems and routers are another sizable draw, as are the substantial power demands for data processing and equipment cooling at data centers. Actual data transmission, on the other hand, chiefly over telephone lines, is a small component — approximately 0.1% — of overall energy demand.
"As far as we know, this is the first estimate of total internet electricity use," said David Sarokin, the Uclue researcher who compiled the data. "The raw numbers were all out there, but they hadn't been assembled in this way before."
