I guess I never really cared noticed that personal computers gave off CO2, and could potentially lead to Global Warming. A UK taskforce is interested in bringing major attention to this issue, though, blaming computing for as much Global Warming as the airline industry. Their focus is to try and get companies to move their major use items, such as e-mail and internet usage, to huge, energy efficient servers, potentialy cutting down on resources by 75%. They may be British, but Al Gore certainly would be proud.
