There's an excellent post on the TechSoup blog about why you should choose a greener computer and a pointer to an online tool called The Electronic Product Environmental Assessment Tool (EPEAT) ― a project of the Environmental Protection Agency and the Green Electronics Council ― that can help you evaluate the environmental friendliness of more than 500 models of computers. (I wrote about this tool and an excellent how to purchase a green computer back on Earth Day in April)
There's a follow up discussion on the TechSoup discussion forums about nonprofits and green computing policies. It's here.
This gives me a good opportunity to do a green geekery dump of some links I've collected ...
