How much energy source consumption/ Co2 production is networking media worldwide responsible for?

I would like to know to what extent is the networking media of the whole world (i.e. internet media cables, wires, routers, switches etc.) contributes to the deterioration of worldwide energy sources. And, if possible, find out how much this affects global warming.How much energy source consumption/ Co2 production is networking media worldwide responsible for?
ooooh, now you speaka my language!





That's really a tough question to answer. We do know that these devices consume quite a bit of energy. The average router or switch will pull about 120-240W, depending on how many ports are used, and remember these are devices that are constantly powered on! Plus on top of what the actual networking devices consume, you have to look at how much energy is used to air condition all the network rooms in the world. Here's a good link about some of this:

More and more products are coming out though that are supposed to be a lot more efficient in their energy use, so as some of the older equipment gets replaced, hopefully these new devices get installed in their places. Industry leaders like google are concentrating a lot more on making their network rooms highly efficient too:

Don't know if this will answer your question completely, but I hope it helps.
