PCs - Off or On?

In a commercial setting turning off PCs can save significant amounts of energy and hence carbon emissions, but it may not always be the most effective solution across an organisation.

Purdue University, Indiana, is trying to ensure its PCs are switched off, but when they're on and idle, even if just for a few minutes, they're used for other work such as research jobs. It means that the university's computer resources (more than 20,000 computers) are used more efficiently and reduces the number that are powered up at any one time.

It's achieved through open-source software, called Condor, which comes from the University of Wisconsin. Purdue is going to make the software available to all of its employees so they can also connect to the system.

A reminder that lateral thinking (or the oft cited 'holistic' approach) is needed to achieve Green goals effectively.
