The original point is more that the original production wastes of making a computer are so nasty that any contributions towards making the running of the thing more environmentally friendly has no practical effect on the balance. The manufacturing and refining processes are so nasty that a PC would have to OUTPUT free, clean energy for hundreds of years to come out even.

Power is a big issue (Score:5, Insightful)
This applies even in the home. Here in California, land of the 14 cent kwh, a 100 watt PC running 24/7 costs $120 per year in power. In a 3 year life the power is more expensive than the CPU or any other major component except perhaps the monitor, sometimes more expensive than the whole PC.
This also plays big on ideas like getting an old computer and putting linux on it to act as a router or music player or other special functions. You are much better off buying a dedicated box like a WRT54G than making use of the "free" old hardware.
And yes, this does have environmental issues, but you can see the problem right away just by looking at costs.

PSU Needs Calculator [jscustompcs.com]
Using this calculator, a sample system I just made up only needed 319 watts of peak power. To get that, I needed to be running the 3gig barton chip, 2 sticks of ram, 2 hard drives, a Radeon X800, sound, NIC, with 3 fans fullblast and 2 cathode tubes, and a dvd player. Keep in mind that's PEAK power required, which means all of that has to be going top speed to get there, which means something along the lines of running 3D mark while copying a dvd from one drive to the other while playing sound while downloading a file over the internet while having all your fans and lights cranked up.

And using a geothermal heat pump is significantly more efficient than using an atmospheric heat pump. The former pumps heat to and from the 50 degree Farenheit ground while the latter tries to pump heat into the hot air during the summer and get heat out of the air during the winter.
Server farms using these type of pumps would save significant amounts of money using the same equipment.

Virtualization is the answer (Score:5, Interesting)
We wrote about the environmental benefits of virtualization on our site [openhosting.com] a while back. I even started a little thread [merit.edu] on Nanog about any numbers on relationship of server utilization and the energy cost, but it looked like few people cared. To see how underutilized your Linux server is, do:
# cat /proc/uptime
1122029.25 1101982.75
The first number is the system uptime in seconds, the second is the number of seconds it's been idle. The number above is from my laptop - 98% idle.
Virtualization is also going to be the way hardware vendors will keep the server price up - suddenly very powerful servers will start making sense. The questions is - who will win - Xen, UML or Linux VServer. We're banking on VServer. :-)

Back in the land of all things sane (i.e. Unix style OSes), I see no reason why NOT to run a billion services on one machine. As long as you've got spare system resources, why shouldn't you make use of them? Why do I NEED the domain controller, file server, mail server, and ftp server to all be different machines? One big Unix box does the job better, and for a lower up front (and longterm!) cost than lots of tiny Windows boxes!
Granted, there are still some issues that can't be overcome. But which really makes more sense, spending millions of dollars on tons of machines and an army of support staff, or spending a few hundred thousand on a couple of redundant machines and an admin or two to maintain them?

Enable PowerNOW! power management (current Linux distros like FC3 support it automagically, some BIOSes don't enable it by default). The CPU runs at 800MHz at 1.1V core while idle, jumping to full speed as needed (just like a notebook). Even at full speed power consumption is about half that of an Intel P4 blast furnace. Run 64-bit Linux and get even more work done per watt.
3) Avoid high-wattage video cards like the GeForce 6800 series in favor of 6600GT's. MASSIVE power consumption difference. Depending on how hard-core a gamer you are, the 6600GT's are good enough and a lot cheaper.
