ribuck writes "Equipment powering the internet accounts for 9.4% of electricity demand in the U.S., and 5.3% of global demand, according to research by David Sarokin at online pay-for-answers service Uclue. Worldwide, that's 868 billion kilowatt-hours per year. The total includes the energy used by desktop computers and monitors (which makes up two-thirds of the total), plus other energy sinks including modems, routers, data processing equipment and cooling equipment."

The first place I would look to conserve energy is turning things off as opposed to standby. Televisions use 23% of their annual electricity while in standby, for VCRs that jumps to 50%. http://www.eere.energy.gov/buildings/info/documents/pdfs/lbnl-42393.pdf [energy.gov] So if we turned monitors and computers and wireless routers and printers etc, completely off when we were not using them the savings would likely be significant. As an added bonus your computer can't be a zombie spam bot when the power is turned off.

What is required is legislation to mandate that say standby can consume no more than 1W, then crank it down over the years. Another one would be legislation to for minimum levels of efficiency in power supplies, 85% would be a good starting point, and then crank it up over the years.

Already the case in most of Europe if you buy a dishwasher, fridge, washer, drier or lots of other household-appliances.
There's a grade for energy-efficiency, where the average for that kind of appliance is a "C" whereas an appliance that uses 30% less than average would earn an A, and an appliance that wastes 30% more energy than average earns an "F".
The stuff has been a huge success -- to the point where appliances that don't rate atleast a "B" are just not marketable at all.
The standard gets stricter automatically: As more and more people buy the energy-efficient appliances, the *average* efficiency improves, so the energy-usage for a "C" gets adjusted accordingly.
Works like a charm.
Some appliances have more than one grade, they grade efficiency on more than one scale. A dishwasher may have a note on it saying:
Energy consumption: A
Water consumption: B
Wash effectiveness: A
Drying effectiveness: A
So, I don't see why a modern TV couldn't be sold with; "Energy consumption: A", "Standby consumption: B".

Many things have changed since early 2000 lowering the amount of power needed for the average home PC to operate. Most users in early 2000 were using CRT monitors which use almost 3 times as much power than a modern LCD. If I took the time to research 2000-2002 vs components in the last two years I bet you will see the power consumption of average hardware is probably close to half as much.
And the average cpu uses a LOT more juice. So does the average video card. Who's buying all those 550 watt PSUs?

Power supplies don't just magically use power when they are on. It takes a load (video card, motherboard, cpu, etc) to be drawing that power.
Now there is a question of efficiency, but that has nothing to do with it's power rating. A 400w power supply with a 60% efficiency rating is going to piss away more electricity in the form of heat that a 550w that is rated at 85% efficiency.

And this will continue to change. People are becoming aware of resource scarcity, and want to insure themselves from rising prices. Witness the rise of cheap power meters such as the Kill-A-Watt. These took years to move over to 240V simply because they couldn't keep up with the demand for 110V items.
Something like a WRAP uses 5 Watts. Use it as a firewall/router/ADSL modem/traffic shaper, and it's going to be a cheaper and smaller solution than the typical 20+ Watt modem/router box.
Even CRTs have dropped in power usage compared to what they used to.
We are rapidly approaching the day when our computers will be fast enough for most tasks, the hard drive will be solid state, the system will be passively cooled and made from reliable parts that will last for decades, drawing minimal power. Any media that won't fit on the solid state hard drive can be stored on the spinning kind and plugged in as needed via USB/eSATA/firewire.
Intel probably doesn't want us to have these systems. AMD may or may not. Via certainly does, and you can bet that for pretty much everyone in the first world there is a market for several of these type of systems at a $300 price point or so. That may be a reduction in profitability for Intel, but it will be a massive new market for others, and getting easier to enter all the time.

Come on, unless they're somehow able to measure electricity used only while a computer user is actively viewing Internet content it's absurd to count desktop computers in the total. Or, alternatively, it's absurd to attribute the electricity usage to "the Internet". It would be valid to estimate the electricity usage of computers and/or data communications equipment, but to try to pin a number on "the Internet" and include multifunction equipment that serves non-Internet functions is just sloppy.
Come to think of it, there are probably lots of FT-2000s that carry some Internet circuits and some PSTN circuits, how do they account for that? What about the 5Es and DMSs that are carrying modem calls? Do they accurately attribute the percentage of the switch's electrical usage based on the percentage of modem vs voice calls?

If your entire employee cost (pay, bonus, worker's comp, medical, office-space, etc.) is only $60,000/year, an employee needs to save less than 10-minutes/week to break even.
One coder measured his own pretty high-end machine (including support for 3 monitors) at less than 140 watts when not doing heavy processing. This doesn't include the monitor which in most systems sleeps after a short period anyway. If we use 150 watts, a 9 hour day, and $100,000 employee cost then break-even happens by the time you have saved 2 minutes 15 seconds per week or less than 30 seconds per day.
Now if it takes 2 watts cooling per watt of usage then the benefits of shutting down are greater. But on the other hand, none of the office buildings where I've worked have metered power or cooling (except for custom auxiliary units) so from the tenant perspective, leaving the machine running has no impact on power or cooling costs.
Sure, for many, waiting for a computer to boot is part of the morning routine and provides an excuse to go fill the coffee cup. But if buildings metered power and cooling usage and if computers were made to save-state and swich off and back on like a light - or at least in just 1-2 seconds - people would be much more willing to power down not only at night but at lunch and whenever they aren't using the machine.

Why should a "desktop" computer crank out so much heat? My son's Mac Mini doesn't. His next computer won't either.
There are better ways to do this.
Besides, most of our energy use is for: lights (could use LED lighting for 1/20 the energy), washers (heating up all that water), and dryers (if we only got rid of those covenants that didn't let people line dry clothes), and machines that aren't even being used - look at that printer in the office, it's on 24/7 but after office hours, who is printing to it?
For that matter, why are our gigapop Internet networks running 24/7 in most places? Couldn't we have master switches and routers with key servers that were on 24/7, and have the "desktops" turn OFF their monitors and even computers when no one was using it? Turn off LAN segments that aren't in use automagically.

If we assume most traffic is one the backbone and that the backbone scales as the number of servers running it. Then we only have a few more years before the power consumed by the internet will be larger than todays total power budget. This seems impossible. Ergo the traffic must be out on the edges.
