How Green Was My PC?

Not very, it seems.

This report contrasts the amount of electricity consumed, and carbon dioxide generated, by two approaches to school computing: one based on conventional PCs, the other on thin clients running open source. The difference is startling:

The Green Model therefore represents a 89% saving in the cost of electricity and a 78% reduction carbon dioxide emissions when compared to the Conventional Model.

And it's going to get worse:

The stated aim of many authorities is to have one computer per child. In addition the exponential growth of the interactive whiteboard in all education sectors is set to achieve one in every classroom.

Bearing in mind that an interactive board runs from a conventional PC with a 600w projector and that there are over 50,000 primary schools in the UK we can predict a ten fold increase in power consumption with concomitant carbon increases over the next five years.

Serious stuff that merits thought and action, quickly.
