We read a lot in the press about global warming and the increasing amount of energy we use. Did you know that the proportion of the total energy we consume which is used to power IT is increasing too?

Most of us have access to cheap broadband and there are many low cost or free ways to do audio and video-conferencing over the internet. Obviously we want to see our family and friends in person but I suspect many of us make unnecessary business trips.
