So how much energy does the internet use?

September 28, 2007

If you’ve ever wondered that, here’s your answer:

I've estimated the electricity consumption for the internet as follows:

US: 350 billion kWh per year

World: 868 billion kWh per year


These numbers represent 9.4% of total US electricity consumption, and 5.3%
of global electricity consumption.


===========================================================

The breakout of the data is as follows:


Annual Electricity Use for the Internet--US and World


Category..........................US Consumption.......World Consumption
.....................................Billion kWh........Billion kWh

(1) Data Centers (includes cooling)......45.................112.5


(2) PCs&Monitors........................235.................588


(3) Modems/routers/etc...................67.................167


(4) Phone network.......................0.4...................1.0


TOTAL ELECTRICITY DEMAND ~350 billion kWh ~868 billion
OF THE INTERNET ........................U.S.................World

Crikey! That’s a lot of power! Time to look for better more sustainable power supplies for PC’s? Perhaps we could all sit at our desks pedaling while we surf…
