I almost never post here, but there I thought I would start ..
I'll talk about Ecological PCs. There is already a lot of the ecolo label that has been created in addition to the European directives (RoHS and Weee).
In the first place, and you must know, the least consume is the laptop. In fact, a regular notebook will consume between 50 and 80% less power (depending on its characteristics) than a regular desktop and CRT monitor (Source Energy Star).
But in the jungle of laptops, you have to know how to find the right green lianne, and here you use the different eco-labels:
EPEAT (Electronic Product Environmental Assessment Tool), on their site there is a comparator of computer product based on ecological criteria. Next if the products meet the criteria (list available) here), the site awards them medals (Bronze, Silver, Gold)
Blue Angel, is a label awarded to different types of products, including computers (criteria for PCs are here
TCO, is a Swedish label that was previously awarded only to computer screens, but now it is spread over different products. We can search the different products according to the label on this page.
Energy Star: This label is one of the oldest, many screens have received this label. The site has a search engine to find products compliant with the Energy Star label
It should be noted that in the EPEAT criteria, the Energy Star label is integrated.
At the level of Portable PCs, there are only 2 who received the EAPEAT gold medal, it's the Dell Latitude 630
Otherwise some Asus notebooks have received the TCO'99 certification, these are the models: M6, M2E, L2D, L2C. But these do not seem to be available for sale anymore.
Basically in a laptop, there are the Dell (2e ranking tied on the ranking for a High Tech Head of GreenPeace (it's worth what it's worth ...))
If you really cannot leave the comfort of your Fixed PC, the same criteria allow you to find products that are a little more "green".
According to EPEAT, only 4 Desktops, were awarded the gold medal: the Dell OptiPlex 740, the Optiplex 745 the HP rp5700 and a Zonbu brand PC (unknown to the battalion)
If you take TCO 2005 certification, there are only Dell that are rewarded, Optiplex 320 and 745.
At the Blue Angel certification level, 3 manufacturers are award-winning, CHerry (Unknown), Fujuitsu for ESPRIMO E56XX, E57XX, E59XX and P56XX, P57XX, P59XX and Maxdata Favorit 1000,3000 and 5000.
If you want a fixed PC is that you are able to mount it yourself, look to take elements that consume as little as possible, which are RoHS compliant.
For the processor, take the models intended for laptop PCs (Intel Core 2 Duo TXXXX) for example, the hard drives also take the 2,5 "models, for the graphics card take one which is cooled without a fan (heatpipe), the more important is food, find food that complies with the label 80 Plus(I advise Fotron Green Power). For screens, check to see if they meet TCO and Energy Star standards.
If your PC is planned for desktop and movie playback, you can choose a VIA motherboard with a built-in processor. The VIA processor is the least energy-intensive, complies with RoHS standards. The VIA C7-D processor is the most environmentally friendly (carbon-reduced processor).
Finally some tips, put your PC in a ventilated place, it will heat less, the fans will turn less. Turn off your PC (unplug the same). Programs such as Folding @ home, or Decrypthon, certainly have a significant scientific scope but it is at the expense of electricity consumption (you choose).
That's it, I'll add links later ..
